From dbbea6713d6096cd1c411cb453a6b71292c78b33 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 26 Feb 2008 14:34:06 +0100 Subject: mac80211: add documentation book Quite a while ago I started this book. The required kernel-doc patches have since gone into the tree so it is now possible to build the book in mainline. The actual documentation is still rather incomplete and not all things are linked into the book, but this enables us to edit the documentation collaboratively, hopefully driver authors can add documentation based on their experience with mac80211.

These devices have -been a problem for Linux users as there is no open-source driver -available. In addition, Broadcom has not released specifications -for the device, and driver availability has been limited to the -binary-only form used in the GPL versions of AP hardware such as the -Linksys WRT54G, and the Windows and OS X drivers. Before this project -began, the only way to use these devices were to use the Windows or -OS X drivers with either the Linuxant or ndiswrapper modules. There -is a strong penalty if this method is used as loading the binary-only -module "taints" the kernel, and no kernel developer will help diagnose -any kernel problems. - -Development ------------ - -This driver has been developed using -a clean-room technique that is described at -http://bcm-specs.sipsolutions.net/ReverseEngineeringProcess. For legal -reasons, none of the clean-room crew works on the on the Linux driver, -and none of the Linux developers sees anything but the specifications, -which are the ultimate product of the reverse-engineering group. - -Software --------- - -Since the release of the 2.6.17 kernel, the bcm43xx driver has been -distributed with the kernel source, and is prebuilt in most, if not -all, distributions. There is, however, additional software that is -required. The firmware used by the chip is the intellectual property -of Broadcom and they have not given the bcm43xx team redistribution -rights to this firmware. Since we cannot legally redistribute -the firmware we cannot include it with the driver. Furthermore, it -cannot be placed in the downloadable archives of any distributing -organization; therefore, the user is responsible for obtaining the -firmware and placing it in the appropriate location so that the driver -can find it when initializing. - -To help with this process, the bcm43xx developers provide a separate -program named bcm43xx-fwcutter to "cut" the firmware out of a -Windows or OS X driver and write the extracted files to the proper -location. This program is usually provided with the distribution; -however, it may be downloaded from - -http://developer.berlios.de/project/showfiles.php?group_id=4547 - -The firmware is available in two versions. V3 firmware is used with -the in-kernel bcm43xx driver that uses a software MAC layer called -SoftMAC, and will have a microcode revision of 0x127 or smaller. The -V4 firmware is used by an out-of-kernel driver employing a variation of -the Devicescape MAC layer known as d80211. Once bcm43xx-d80211 reaches -a satisfactory level of development, it will replace bcm43xx-softmac -in the kernel as it is much more flexible and powerful. - -A source for the latest V3 firmware is - -http://downloads.openwrt.org/sources/wl_apsta-3.130.20.0.o - -Once this file is downloaded, the command -'bcm43xx-fwcutter -w ' -will extract the microcode and write it to directory -. The correct directory will depend on your distribution; -however, most use '/lib/firmware'. Once this step is completed, -the bcm3xx driver should load when the system is booted. To see -any messages relating to the driver, issue the command 'dmesg | -grep bcm43xx' from a terminal window. If there are any problems, -please send that output to Bcm43xx-dev@lists.berlios.de. - -Although the driver has been in-kernel since 2.6.17, the earliest -version is quite limited in its capability. Patches that include -all features of later versions are available for the stable kernel -versions from 2.6.18. These will be needed if you use a BCM4318, -or a PCI Express version (BCM4311 and BCM4312). In addition, if you -have an early BCM4306 and more than 1 GB RAM, your kernel will need -to be patched. These patches, which are being updated regularly, -are available at ftp://lwfinger.dynalias.org/patches. Look for -combined_2.6.YY.patch. Of course you will need kernel source downloaded -from kernel.org, or the source from your distribution. - -If you build your own kernel, please enable CONFIG_BCM43XX_DEBUG -and CONFIG_IEEE80211_SOFTMAC_DEBUG.

The last remaining issue was support for ancient dual port SysKonnect fiber boards, and the skge driver now does these correctly (p.s. sk98lin was always broken on these old dual port boards anyway).

In particular, + PCI and I/O devices have been reinitialized and are + in a clean, consistent state. +-- As the dump is performed, the dumped memory becomes + immediately available to the system for normal use. +-- After the dump is completed, no further reboots are + required; the system will be fully usable, and running + in it's normal, production mode on it normal kernel. + +The above can only be accomplished by coordination with, +and assistance from the hypervisor. The procedure is +as follows: + +-- When a system crashes, the hypervisor will save + the low 256MB of RAM to a previously registered + save region. It will also save system state, system + registers, and hardware PTE's. + +-- After the low 256MB area has been saved, the + hypervisor will reset PCI and other hardware state. + It will *not* clear RAM. It will then launch the + bootloader, as normal. + +-- The freshly booted kernel will notice that there + is a new node (ibm,dump-kernel) in the device tree, + indicating that there is crash data available from + a previous boot. It will boot into only 256MB of RAM, + reserving the rest of system memory. + +-- Userspace tools will parse /sys/kernel/release_region + and read /proc/vmcore to obtain the contents of memory, + which holds the previous crashed kernel. The userspace + tools may copy this info to disk, or network, nas, san, + iscsi, etc. as desired. + + For Example: the values in /sys/kernel/release-region + would look something like this (address-range pairs). + CPU:0x177fee000-0x10000: HPTE:0x177ffe020-0x1000: / + DUMP:0x177fff020-0x10000000, 0x10000000-0x16F1D370A + +-- As the userspace tools complete saving a portion of + dump, they echo an offset and size to + /sys/kernel/release_region to release the reserved + memory back to general use. + + An example of this is: + "echo 0x40000000 0x10000000 > /sys/kernel/release_region" + which will release 256MB at the 1GB boundary. + +Please note that the hypervisor-assisted dump feature +is only available on Power6-based systems with recent +firmware versions. + +Implementation details: +---------------------- + +During boot, a check is made to see if firmware supports +this feature on this particular machine. If it does, then +we check to see if a active dump is waiting for us. If yes +then everything but 256 MB of RAM is reserved during early +boot. This area is released once we collect a dump from user +land scripts that are run. If there is dump data, then +the /sys/kernel/release_region file is created, and +the reserved memory is held. + +If there is no waiting dump data, then only the highest +256MB of the ram is reserved as a scratch area. This area +is *not* released: this region will be kept permanently +reserved, so that it can act as a receptacle for a copy +of the low 256MB in the case a crash does occur. See, +however, "open issues" below, as to whether +such a reserved region is really needed. + +Currently the dump will be copied from /proc/vmcore to a +a new file upon user intervention. The starting address +to be read and the range for each data point in provided +in /sys/kernel/release_region. + +The tools to examine the dump will be same as the ones +used for kdump. + +General notes: +-------------- +Security: please note that there are potential security issues +with any sort of dump mechanism. In particular, plaintext +(unencrypted) data, and possibly passwords, may be present in +the dump data. Userspace tools must take adequate precautions to +preserve security. + +Open issues/ToDo: +------------ + o The various code paths that tell the hypervisor that a crash + occurred, vs. it simply being a normal reboot, should be + reviewed, and possibly clarified/fixed. + + o Instead of using /sys/kernel, should there be a /sys/dump + instead? There is a dump_subsys being created by the s390 code, + perhaps the pseries code should use a similar layout as well. + + o Is reserving a 256MB region really required? The goal of + reserving a 256MB scratch area is to make sure that no + important crash data is clobbered when the hypervisor + save low mem to the scratch area. But, if one could assure + that nothing important is located in some 256MB area, then + it would not need to be reserved. Something that can be + improved in subsequent versions. + + o Still working the kdump team to integrate this with kdump, + some work remains but this would not affect the current + patches. + + o Still need to write a shell script, to copy the dump away. + Currently I am parsing it manually. -- cgit v1.2.3 From ecc6cd73b7ccfa10c1f07d017fc7f62fe78eaab5 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Tue, 26 Feb 2008 11:43:20 +1100 Subject: [POWERPC] Start removing linux,network-index in favour of aliases This patch alters the bootwrapper for a number of machines (roubhly all 4xx based cuboot or treeboot platforms) to use aliases instead of the linux,network-index hack to work out which MAC address to attach to which ethernet device node. The now obsolete linux,network-index properties are removed from the corresponding device trees. This won't break backwards compatiblity, because in cases where this fixup code is relevant, the device tree is part of the kernel image. The references to linux,network-index are removed from booting-without-of.txt. Not only is it now deprecated, but as a hack applicable only when the device tree blob and fixup code were in the same image, this property never belonged in booting-without-of.txt which describes the interface between the kernel and firmware or bootloaders which produce a device tree. By the time the device tree reaches the kernel, all the MAC addresses must be fully filled in.

Although router's job may be as simple as taking your local network -traffic, converting it to WAN format and piping it through the WAN link, these -devices are notoriously expensive, with prices as much as 2 - 5 times higher -then the price of a typical PC box. - -Alternatively, considering robustness and multitasking capabilities of Linux, -an internal router can be built (most routers use some sort of stripped down -Unix-like operating system anyway). With a number of relatively inexpensive WAN -interface cards available on the market, a perfectly usable router can be -built for less than half a price of an external router. Yet a Linux box -acting as a router can still be used for other purposes, such as fire-walling, -running FTP, WWW or DNS server, etc. - -This kernel module introduces the notion of a WAN Link Driver (WLD) to Linux -operating system and provides generic hardware-independent services for such -drivers. Why can existing Linux network device interface not be used for -this purpose? Well, it can. However, there are a few key differences between -a typical network interface (e.g. Ethernet) and a WAN link. - -Many WAN protocols, such as X.25 and frame relay, allow for multiple logical -connections (known as `virtual circuits' in X.25 terminology) over a single -physical link. Each such virtual circuit may (and almost always does) lead -to a different geographical location and, therefore, different network. As a -result, it is the virtual circuit, not the physical link, that represents a -route and, therefore, a network interface in Linux terms. - -To further complicate things, virtual circuits are usually volatile in nature -(excluding so called `permanent' virtual circuits or PVCs). With almost no -time required to set up and tear down a virtual circuit, it is highly desirable -to implement on-demand connections in order to minimize network charges. So -unlike a typical network driver, the WAN driver must be able to handle multiple -network interfaces and cope as multiple virtual circuits come into existence -and go away dynamically. - -Last, but not least, WAN configuration is much more complex than that of say -Ethernet and may well amount to several dozens of parameters. Some of them -are "link-wide" while others are virtual circuit-specific. The same holds -true for WAN statistics which is by far more extensive and extremely useful -when troubleshooting WAN connections. Extending the ifconfig utility to suit -these needs may be possible, but does not seem quite reasonable. Therefore, a -WAN configuration utility and corresponding application programmer's interface -is needed for this purpose. - -Most of these problems are taken care of by this module. Its goal is to -provide a user with more-or-less standard look and feel for all WAN devices and -assist a WAN device driver writer by providing common services, such as: - - o User-level interface via /proc file system - o Centralized configuration - o Device management (setup, shutdown, etc.) - o Network interface management (dynamic creation/destruction) - o Protocol encapsulation/decapsulation - -To ba able to use the Linux WAN Router you will also need a WAN Tools package -available from - - ftp.sangoma.com/pub/linux/current_wanpipe/wanpipe-X.Y.Z.tgz - -where vX.Y.Z represent the wanpipe version number. - -For technical questions and/or comments please e-mail to ncorbic@sangoma.com. -For general inquiries please contact Sangoma Technologies Inc. by - - Hotline: 1-800-388-2475 (USA and Canada, toll free) - Phone: (905) 474-1990 ext: 106 - Fax: (905) 474-9223 - E-mail: dm@sangoma.com (David Mandelstam) - WWW: http://www.sangoma.com - - -INSTALLATION - -Please read the WanpipeForLinux.pdf manual on how to -install the WANPIPE tools and drivers properly. - - -After installing wanpipe package: /usr/local/wanrouter/doc. -On the ftp.sangoma.com : /linux/current_wanpipe/doc - - -COPYRIGHT AND LICENSING INFORMATION - -This program is free software; you can redistribute it and/or modify it under -the terms of the GNU General Public License as published by the Free Software -Foundation; either version 2, or (at your option) any later version. - -This program is distributed in the hope that it will be useful, but WITHOUT -ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS -FOR A PARTICULAR PURPOSE.

Success of the WANPIPE -together with the next major release of Linux kernel in summer 1996 commanded -adequate changes to the WANPIPE code to take full advantage of new Linux -features. - -Instead of continuing developing proprietary interface tied to Sangoma WAN -cards, we decided to separate all hardware-independent code into a separate -module and defined two levels of interfaces - one for user-level applications -and another for kernel-level WAN drivers. WANPIPE is now implemented as a -WAN driver compliant with the WAN Link Driver interface. Also a general -purpose WAN configuration utility and a set of shell scripts was developed to -support WAN router at the user level. - -Many useful ideas concerning hardware-independent interface implementation -were given by Mike McLagan and his implementation -of the Frame Relay router and drivers for Sangoma cards (dlci/sdla). - -With the new implementation of the APIs being incorporated into the WANPIPE, -a special thank goes to Alan Cox in providing insight into BSD sockets. - -Special thanks to all the WANPIPE users who performed field-testing, reported -bugs and made valuable comments and suggestions that help us to improve this -product. - - - -NEW IN THIS RELEASE - - o Updated the WANCFG utility - Calls the pppconfig to configure the PPPD - for async connections. - - o Added the PPPCONFIG utility - Used to configure the PPPD daemon for the - WANPIPE Async PPP and standard serial port. - The wancfg calls the pppconfig to configure - the pppd. - - o Fixed the PCI autodetect feature. - The SLOT 0 was used as an autodetect option - however, some high end PC's slot numbers start - from 0. - - o This release has been tested with the new backupd - daemon release. - - -PRODUCT COMPONENTS AND RELATED FILES - -/etc: (or user defined) - wanpipe1.conf default router configuration file -

The next event is currently defined to be periodic, with its -period defined at compile time. The setup and selection of the event device -for various event driven functionalities is hardwired into the architecture -dependent code. This results in duplicated code across all architectures and -makes it extremely difficult to change the configuration of the system to use -event interrupt devices other than those already built into the -architecture. Another implication of the current design is that it is necessary -to touch all the architecture-specific implementations in order to provide new -functionality like high resolution timers or dynamic ticks. - -The clock events subsystem tries to address this problem by providing a generic -solution to manage clock event devices and their usage for the various clock -event driven kernel functionalities. The goal of the clock event subsystem is -to minimize the clock event related architecture dependent code to the pure -hardware related handling and to allow easy addition and utilization of new -clock event devices. It also minimizes the duplicated code across the -architectures as it provides generic functionality down to the interrupt -service handler, which is almost inherently hardware dependent. - -Clock event devices are registered either by the architecture dependent boot -code or at module insertion time. Each clock event device fills a data -structure with clock-specific property parameters and callback functions. The -clock event management decides, by using the specified property parameters, the -set of system functions a clock event device will be used to support. This -includes the distinction of per-CPU and per-system global event devices. - -System-level global event devices are used for the Linux periodic tick. Per-CPU -event devices are used to provide local CPU functionality such as process -accounting, profiling, and high resolution timers. - -The management layer assigns one or more of the following functions to a clock -event device: - - system global periodic tick (jiffies update) - - cpu local update_process_times - - cpu local profiling - - cpu local next event interrupt (non periodic mode) - -The clock event device delegates the selection of those timer interrupt related -functions completely to the management layer. The clock management layer stores -a function pointer in the device description structure, which has to be called -from the hardware level handler. This removes a lot of duplicated code from the -architecture specific timer interrupt handlers and hands the control over the -clock event devices and the assignment of timer interrupt related functionality -to the core code. - -The clock event layer API is rather small.

Such a design still led to rather large - timing inaccuracies. Cascading is a fundamental property of the timer - wheel concept, it cannot be 'designed out' without unevitably - degrading other portions of the timers.c code in an unacceptable way. - -- the implementation of the current posix-timer subsystem on top of - the timer wheel has already introduced a quite complex handling of - the required readjusting of absolute CLOCK_REALTIME timers at - settimeofday or NTP time - further underlying our experience by - example: that the timer wheel data structure is too rigid for high-res - timers. - -- the timer wheel code is most optimal for use cases which can be - identified as "timeouts". Such timeouts are usually set up to cover - error conditions in various I/O paths, such as networking and block - I/O. The vast majority of those timers never expire and are rarely - recascaded because the expected correct event arrives in time so they - can be removed from the timer wheel before any further processing of - them becomes necessary. Thus the users of these timeouts can accept - the granularity and precision tradeoffs of the timer wheel, and - largely expect the timer subsystem to have near-zero overhead. - Accurate timing for them is not a core purpose - in fact most of the - timeout values used are ad-hoc. For them it is at most a necessary - evil to guarantee the processing of actual timeout completions - (because most of the timeouts are deleted before completion), which - should thus be as cheap and unintrusive as possible. - -The primary users of precision timers are user-space applications that -utilize nanosleep, posix-timers and itimer interfaces. Also, in-kernel -users like drivers and subsystems which require precise timed events -(e.g. multimedia) can benefit from the availability of a separate -high-resolution timer subsystem as well. - -While this subsystem does not offer high-resolution clock sources just -yet, the hrtimer subsystem can be easily extended with high-resolution -clock capabilities, and patches for that exist and are maturing quickly. -The increasing demand for realtime and multimedia applications along -with other potential users for precise timers gives another reason to -separate the "timeout" and "precise timer" subsystems. - -Another potential benefit is that such a separation allows even more -special-purpose optimization of the existing timer wheel for the low -resolution and low precision use cases - once the precision-sensitive -APIs are separated from the timer wheel and are migrated over to -hrtimers. E.g. we could decrease the frequency of the timeout subsystem -from 250 Hz to 100 HZ (or even smaller). - -hrtimer subsystem implementation details ----------------------------------------- - -the basic design considerations were: - -- simplicity - -- data structure not bound to jiffies or any other granularity. All the - kernel logic works at 64-bit nanoseconds resolution - no compromises. - -- simplification of existing, timing related kernel code - -another basic requirement was the immediate enqueueing and ordering of -timers at activation time. After looking at several possible solutions -such as radix trees and hashes, we chose the red black tree as the basic -data structure. Rbtrees are available as a library in the kernel and are -used in various performance-critical areas of e.g. memory management and -file systems. The rbtree is solely used for time sorted ordering, while -a separate list is used to give the expiry code fast access to the -queued timers, without having to walk the rbtree. - -(This separate list is also useful for later when we'll introduce -high-resolution clocks, where we need separate pending and expired -queues while keeping the time-order intact.) - -Time-ordered enqueueing is not purely for the purposes of -high-resolution clocks though, it also simplifies the handling of -absolute timers based on a low-resolution CLOCK_REALTIME. The existing -implementation needed to keep an extra list of all armed absolute -CLOCK_REALTIME timers along with complex locking. In case of -settimeofday and NTP, all the timers (!) had to be dequeued, the -time-changing code had to fix them up one by one, and all of them had to -be enqueued again. The time-ordered enqueueing and the storage of the -expiry time in absolute time units removes all this complex and poorly -scaling code from the posix-timer implementation - the clock can simply -be set without having to touch the rbtree. This also makes the handling -of posix-timers simpler in general. - -The locking and per-CPU behavior of hrtimers was mostly taken from the -existing timer wheel code, as it is mature and well suited. Sharing code -was not really a win, due to the different data structures. Also, the -hrtimer functions now have clearer behavior and clearer names - such as -hrtimer_try_to_cancel() and hrtimer_cancel() [which are roughly -equivalent to del_timer() and del_timer_sync()] - so there's no direct -1:1 mapping between them on the algorithmical level, and thus no real -potential for code sharing either. - -Basic data types: every time value, absolute or relative, is in a -special nanosecond-resolution type: ktime_t. The kernel-internal -representation of ktime_t values and operations is implemented via -macros and inline functions, and can be switched between a "hybrid -union" type and a plain "scalar" 64bit nanoseconds representation (at -compile time). The hybrid union type optimizes time conversions on 32bit -CPUs. This build-time-selectable ktime_t storage format was implemented -to avoid the performance impact of 64-bit multiplications and divisions -on 32bit CPUs. Such operations are frequently necessary to convert -between the storage formats provided by kernel and userspace interfaces -and the internal time format.

The next event is currently defined to be periodic, with its +period defined at compile time. The setup and selection of the event device +for various event driven functionalities is hardwired into the architecture +dependent code. This results in duplicated code across all architectures and +makes it extremely difficult to change the configuration of the system to use +event interrupt devices other than those already built into the +architecture. Another implication of the current design is that it is necessary +to touch all the architecture-specific implementations in order to provide new +functionality like high resolution timers or dynamic ticks. + +The clock events subsystem tries to address this problem by providing a generic +solution to manage clock event devices and their usage for the various clock +event driven kernel functionalities. The goal of the clock event subsystem is +to minimize the clock event related architecture dependent code to the pure +hardware related handling and to allow easy addition and utilization of new +clock event devices. It also minimizes the duplicated code across the +architectures as it provides generic functionality down to the interrupt +service handler, which is almost inherently hardware dependent. + +Clock event devices are registered either by the architecture dependent boot +code or at module insertion time. Each clock event device fills a data +structure with clock-specific property parameters and callback functions. The +clock event management decides, by using the specified property parameters, the +set of system functions a clock event device will be used to support. This +includes the distinction of per-CPU and per-system global event devices. + +System-level global event devices are used for the Linux periodic tick. Per-CPU +event devices are used to provide local CPU functionality such as process +accounting, profiling, and high resolution timers. + +The management layer assigns one or more of the following functions to a clock +event device: + - system global periodic tick (jiffies update) + - cpu local update_process_times + - cpu local profiling + - cpu local next event interrupt (non periodic mode) + +The clock event device delegates the selection of those timer interrupt related +functions completely to the management layer. The clock management layer stores +a function pointer in the device description structure, which has to be called +from the hardware level handler. This removes a lot of duplicated code from the +architecture specific timer interrupt handlers and hands the control over the +clock event devices and the assignment of timer interrupt related functionality +to the core code. + +The clock event layer API is rather small.

Also, the +hrtimer functions now have clearer behavior and clearer names - such as +hrtimer_try_to_cancel() and hrtimer_cancel() [which are roughly +equivalent to del_timer() and del_timer_sync()] - so there's no direct +1:1 mapping between them on the algorithmical level, and thus no real +potential for code sharing either. + +Basic data types: every time value, absolute or relative, is in a +special nanosecond-resolution type: ktime_t. The kernel-internal +representation of ktime_t values and operations is implemented via +macros and inline functions, and can be switched between a "hybrid +union" type and a plain "scalar" 64bit nanoseconds representation (at +compile time). The hybrid union type optimizes time conversions on 32bit +CPUs. This build-time-selectable ktime_t storage format was implemented +to avoid the performance impact of 64-bit multiplications and divisions +on 32bit CPUs. Such operations are frequently necessary to convert +between the storage formats provided by kernel and userspace interfaces +and the internal time format. (See include/linux/ktime.h for further +details.) + +hrtimers - rounding of timer values +----------------------------------- + +the hrtimer code will round timer events to lower-resolution clocks +because it has to. Otherwise it will do no artificial rounding at all. + +one question is, what resolution value should be returned to the user by +the clock_getres() interface. This will return whatever real resolution +a given clock has - be it low-res, high-res, or artificially-low-res. + +hrtimers - testing and verification +---------------------------------- + +We used the high-resolution clock subsystem ontop of hrtimers to verify +the hrtimer implementation details in praxis, and we also ran the posix +timer tests in order to ensure specification compliance. We also ran +tests on low-resolution clocks. + +The hrtimer patch converts the following kernel functionality to use +hrtimers: + + - nanosleep + - itimers + - posix-timers + +The conversion of nanosleep and posix-timers enabled the unification of +nanosleep and clock_nanosleep. + +The code was successfully compiled for the following platforms: + + i386, x86_64, ARM, PPC, PPC64, IA64 + +The code was run-tested on the following platforms: + + i386(UP/SMP), x86_64(UP/SMP), ARM, PPC + +hrtimers were also integrated into the -rt tree, along with a +hrtimers-based high-resolution clock implementation, so the hrtimers +code got a healthy amount of testing and use in practice. + + Thomas Gleixner, Ingo Molnar diff --git a/Documentation/timers/timer_stats.txt b/Documentation/timers/timer_stats.txt new file mode 100644 index 000000000000..20d368c59814 --- /dev/null +++ b/Documentation/timers/timer_stats.txt @@ -0,0 +1,73 @@ +timer_stats - timer usage statistics +------------------------------------ + +timer_stats is a debugging facility to make the timer (ab)usage in a Linux +system visible to kernel and userspace developers.

Kale + + + + + This file is licensed under the terms of the GNU General Public License + version 2. This program is licensed "as is" without any warranty of any + kind, whether express or implied. + + + + + + + + Introduction + + kgdb is a source level debugger for linux kernel. It is used along + with gdb to debug a linux kernel. The expectation is that gdb can + be used to "break in" to the kernel to inspect memory, variables + and look through a cal stack information similar to what an + application developer would use gdb for. It is possible to place + breakpoints in kernel code and perform some limited execution + stepping. + + + Two machines are required for using kgdb. One of these machines is a + development machine and the other is a test machine. The kernel + to be debugged runs on the test machine. The development machine + runs an instance of gdb against the vmlinux file which contains + the symbols (not boot image such as bzImage, zImage, uImage...). + In gdb the developer specifies the connection parameters and + connects to kgdb. Depending on which kgdb I/O modules exist in + the kernel for a given architecture, it may be possible to debug + the test machine's kernel with the development machine using a + rs232 or ethernet connection. + + + + Compiling a kernel + + To enable CONFIG_KGDB, look under the "Kernel debugging" + and then select "KGDB: kernel debugging with remote gdb". + + + Next you should choose one of more I/O drivers to interconnect debugging + host and debugged target. Early boot debugging requires a KGDB + I/O driver that supports early debugging and the driver must be + built into the kernel directly. Kgdb I/O driver configuration + takes place via kernel or module parameters, see following + chapter. + + + The kgdb test compile options are described in the kgdb test suite chapter. + + + + + Enable kgdb for debugging + + In order to use kgdb you must activate it by passing configuration + information to one of the kgdb I/O drivers. If you do not pass any + configuration information kgdb will not do anything at all. Kgdb + will only actively hook up to the kernel trap hooks if a kgdb I/O + driver is loaded and configured. If you unconfigure a kgdb I/O + driver, kgdb will unregister all the kernel hook points. + + + All drivers can be reconfigured at run time, if + CONFIG_SYSFS and CONFIG_MODULES + are enabled, by echo'ing a new config string to + /sys/module/<driver>/parameter/<option>. + The driver can be unconfigured by passing an empty string. You cannot + change the configuration while the debugger is attached. Make sure + to detach the debugger with the detach command + prior to trying unconfigure a kgdb I/O driver. + + + Kernel parameter: kgdbwait + + The Kernel command line option kgdbwait makes + kgdb wait for a debugger connection during booting of a kernel. You + can only use this option you compiled a kgdb I/O driver into the + kernel and you specified the I/O driver configuration as a kernel + command line option. The kgdbwait parameter should always follow the + configuration parameter for the kgdb I/O driver in the kernel + command line else the I/O driver will not be configured prior to + asking the kernel to use it to wait. + + + The kernel will stop and wait as early as the I/O driver and + architecture will allow when you use this option. If you build the + kgdb I/O driver as a kernel module kgdbwait will not do anything. + + + + Kernel parameter: kgdboc + + The kgdboc driver was originally an abbreviation meant to stand for + "kgdb over console". Kgdboc is designed to work with a single + serial port as example, and it was meant to cover the circumstance + where you wanted to use a serial console as your primary console as + well as using it to perform kernel debugging. + + + Using kgdboc + + You can configure kgdboc via sysfs or a module or kernel boot line + parameter depending on if you build with CONFIG_KGDBOC as a module + or built-in. + + From the module load or build-in + kgdboc=<tty-device>,[baud] + + The example here would be if your console port was typically ttyS0, you would use something like kgdboc=ttyS0,115200 or on the ARM Versatile AB you would likely use kgdboc=ttyAMA0,115200 + + + From sysfs + echo ttyS0 > /sys/module/kgdboc/parameters/kgdboc + + + + + NOTE: Kgdboc does not support interrupting the target via the + gdb remote protocol. You must manually send a sysrq-g unless you + have a proxy that splits console output to a terminal problem and + has a separate port for the debugger to connect to that sends the + sysrq-g for you. + + When using kgdboc with no debugger proxy, you can end up + connecting the debugger for one of two entry points. If an + exception occurs after you have loaded kgdboc a message should print + on the console stating it is waiting for the debugger. In case you + disconnect your terminal program and then connect the debugger in + its place. If you want to interrupt the target system and forcibly + enter a debug session you have to issue a Sysrq sequence and then + type the letter g. Then you disconnect the + terminal session and connect gdb. Your options if you don't like + this are to hack gdb to send the sysrq-g for you as well as on the + initial connect, or to use a debugger proxy that allows an + unmodified gdb to do the debugging. + + + + kgdboc internals + + The kgdboc driver is actually a very thin driver that relies on the + underlying low level to the hardware driver having "polling hooks" + which the to which the tty driver is attached. In the initial + implementation of kgdboc it the serial_core was changed to expose a + low level uart hook for doing polled mode reading and writing of a + single character while in an atomic context. When kgdb makes an I/O + request to the debugger, kgdboc invokes a call back in the serial + core which in turn uses the call back in the uart driver. It is + certainly possible to extend kgdboc to work with non-uart based + consoles in the future. + + + When using kgdboc with a uart, the uart driver must implement two callbacks in the struct uart_ops. Example from drivers/8250.c: +#ifdef CONFIG_CONSOLE_POLL + .poll_get_char = serial8250_get_poll_char, + .poll_put_char = serial8250_put_poll_char, +#endif + + Any implementation specifics around creating a polling driver use the + #ifdef CONFIG_CONSOLE_POLL, as shown above. + Keep in mind that polling hooks have to be implemented in such a way + that they can be called from an atomic context and have to restore + the state of the uart chip on return such that the system can return + to normal when the debugger detaches. You need to be very careful + with any kind of lock you consider, because failing here is most + going to mean pressing the reset button. + + + + + Kernel parameter: kgdbcon + + Kgdb supports using the gdb serial protocol to send console messages + to the debugger when the debugger is connected and running. There + are two ways to activate this feature. + + Activate with the kernel command line option: + kgdbcon + + Use sysfs before configuring an io driver + + echo 1 > /sys/module/kgdb/parameters/kgdb_use_con + + + NOTE: If you do this after you configure the kgdb I/O driver, the + setting will not take effect until the next point the I/O is + reconfigured. + + + + + + IMPORTANT NOTE: Using this option with kgdb over the console + (kgdboc) or kgdb over ethernet (kgdboe) is not supported. + + + + + Connecting gdb + + If you are using kgdboc, you need to have used kgdbwait as a boot + argument, issued a sysrq-g, or the system you are going to debug + has already taken an exception and is waiting for the debugger to + attach before you can connect gdb. + + + If you are not using different kgdb I/O driver other than kgdboc, + you should be able to connect and the target will automatically + respond. + + + Example (using a serial port): + + + % gdb ./vmlinux + (gdb) set remotebaud 115200 + (gdb) target remote /dev/ttyS0 + + + Example (kgdb to a terminal server): + + + % gdb ./vmlinux + (gdb) target remote udp:192.168.2.2:6443 + + + Example (kgdb over ethernet): + + + % gdb ./vmlinux + (gdb) target remote udp:192.168.2.2:6443 + + + Once connected, you can debug a kernel the way you would debug an + application program. + + + If you are having problems connecting or something is going + seriously wrong while debugging, it will most often be the case + that you want to enable gdb to be verbose about its target + communications. You do this prior to issuing the target + remote command by typing in: set remote debug 1 + + + + kgdb Test Suite + + When kgdb is enabled in the kernel config you can also elect to + enable the config parameter KGDB_TESTS. Turning this on will + enable a special kgdb I/O module which is designed to test the + kgdb internal functions. + + + The kgdb tests are mainly intended for developers to test the kgdb + internals as well as a tool for developing a new kgdb architecture + specific implementation. These tests are not really for end users + of the Linux kernel. The primary source of documentation would be + to look in the drivers/misc/kgdbts.c file. + + + The kgdb test suite can also be configured at compile time to run + the core set of tests by setting the kernel config parameter + KGDB_TESTS_ON_BOOT. This particular option is aimed at automated + regression testing and does not require modifying the kernel boot + config arguments. If this is turned on, the kgdb test suite can + be disabled by specifying "kgdbts=" as a kernel boot argument. + + + + Architecture Specifics + + Kgdb is organized into three basic components: + + kgdb core + + The kgdb core is found in kernel/kgdb.c. It contains: + + All the logic to implement the gdb serial protocol + A generic OS exception handler which includes sync'ing the processors into a stopped state on an multi cpu system. + The API to talk to the kgdb I/O drivers + The API to make calls to the arch specific kgdb implementation + The logic to perform safe memory reads and writes to memory while using the debugger + A full implementation for software breakpoints unless overridden by the arch + + + + kgdb arch specific implementation + + This implementation is generally found in arch/*/kernel/kgdb.c. + As an example, arch/x86/kernel/kgdb.c contains the specifics to + implement HW breakpoint as well as the initialization to + dynamically register and unregister for the trap handlers on + this architecture. The arch specific portion implements: + + contains an arch specific trap catcher which + invokes kgdb_handle_exception() to start kgdb about doing its + work + translation to and from gdb specific packet format to pt_regs + Registration and unregistration of architecture specific trap hooks + Any special exception handling and cleanup + NMI exception handling and cleanup + (optional)HW breakpoints + + + + kgdb I/O driver + + Each kgdb I/O driver has to provide an configuration + initialization, and cleanup handler for when it + unloads/unconfigures. Any given kgdb I/O driver has to operate + very closely with the hardware and must do it in such a way that + does not enable interrupts or change other parts of the system + context without completely restoring them. Every kgdb I/O + driver must provide a read and write character interface. The + kgdb core will repeatedly "poll" a kgdb I/O driver for characters + when it needs input. The I/O driver is expected to return + immediately if there is no data available. Doing so allows for + the future possibility to touch watch dog hardware in such a way + as to have a target system not reset when these are enabled. + + + + + + If you are intent on adding kgdb architecture specific support + for a new architecture, the architecture should define + HAVE_ARCH_KGDB in the architecture specific + Kconfig file. This will enable kgdb for the architecture, and + at that point you must create an architecture specific kgdb + implementation. + + + There are a few flags which must be set on every architecture in + their <asm/kgdb.h> file. These are: + + + + NUMREGBYTES: The size in bytes of all of the registers, so + that we can ensure they will all fit into a packet. + + + BUFMAX: The size in bytes of the buffer GDB will read into. + This must be larger than NUMREGBYTES. + + + CACHE_FLUSH_IS_SAFE: Set to 1 if it is always safe to call + flush_cache_range or flush_icache_range. On some architectures, + these functions may not be safe to call on SMP since we keep other + CPUs in a holding pattern. + + + + + + There are also the following functions for the common backend, + found in kernel/kgdb.c, that must be supplied by the + architecture-specific backend unless marked as (optional), in + which case a default function maybe used if the architecture + does not need to provide a specific implementation. + +!Iinclude/linux/kgdb.h + + + Credits + + The following people have contributed to this document: + + Amit Kaleamitkale@linsyssoft.com + Tom Rinitrini@kernel.crashing.org + Jason Wesseljason.wessel@windriver.com + + + + + diff --git a/MAINTAINERS b/MAINTAINERS index e46775868019..3eceebb48c92 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -2319,6 +2319,12 @@ L: linux-kernel@vger.kernel.org L: kexec@lists.infradead.org S: Maintained +KGDB +P: Jason Wessel +M: jason.wessel@windriver.com +L: kgdb-bugreport@lists.sourceforge.net +S: Maintained + KPROBES P: Ananth N Mavinakayanahalli M: ananth@in.ibm.com diff --git a/include/linux/kgdb.h b/include/linux/kgdb.h index b0985b79b638..9757b1a6d9dc 100644 --- a/include/linux/kgdb.h +++ b/include/linux/kgdb.h @@ -22,31 +22,34 @@ struct pt_regs; -/* - * kgdb_skipexception - Bail out of KGDB when we've been triggered. +/** + * kgdb_skipexception - (optional) exit kgdb_handle_exception early * @exception: Exception vector number * @regs: Current &struct pt_regs. * - * On some architectures we need to skip a breakpoint exception when - * it occurs after a breakpoint has been removed. + * On some architectures it is required to skip a breakpoint + * exception when it occurs after a breakpoint has been removed. + * This can be implemented in the architecture specific portion of + * for kgdb. */ extern int kgdb_skipexception(int exception, struct pt_regs *regs); -/* - * kgdb_post_primary_code - Save error vector/code numbers. +/** + * kgdb_post_primary_code - (optional) Save error vector/code numbers. * @regs: Original pt_regs. * @e_vector: Original error vector. * @err_code: Original error code. * - * This is needed on architectures which support SMP and KGDB. - * This function is called after all the secondary cpus have been put - * to a know spin state and the primary CPU has control over KGDB. + * This is usually needed on architectures which support SMP and + * KGDB.

This is done to avoid LSM registration clashes in case of more than one bult-in module. User can choose a security module to enable at boot. If no security= boot parameter is specified, only the first LSM asking for registration will be loaded. An invalid security module name will be treated as if no module has been chosen. LSM modules must check now if they are allowed to register by calling security_module_enable(ops) first. Modify SELinux and SMACK to do so. Do not let SMACK register smackfs if it was not chosen on boot. Smackfs assumes that smack hooks are registered and the initial task security setup (swapper->security) is done.

In fact, in some architectures, the searching ranges on +events are limited in the same socket or node where the CPU locates, +while the load balance on tick searchs all. + +For example, assume CPU Z is relatively far from CPU X. Even if CPU Z +is idle while CPU X and the siblings are busy, scheduler can't migrate +woken task B from X to Z since it is out of its searching range. +As the result, task B on CPU X need to wait task A or wait load balance +on the next tick. For some applications in special situation, waiting +1 tick may be too long. + +The 'sched_relax_domain_level' file allows you to request changing +this searching range as you like.

Therefore you will +not be able to run realtime tasks as any user other than root until you have +done that, even if the user has the rights to run processes with realtime +priority! + + +2.3 Basis for grouping tasks +---------------------------- + +There are two compile-time settings for allocating CPU bandwidth. These are +configured using the "Basis for grouping tasks" multiple choice menu under +General setup > Group CPU Scheduler: + +a.

Future plans +=============== + +There is work in progress to make the scheduling period for each group +("/sys/kernel/uids//cpu_rt_period_us" or +"/cgroup//cpu.rt_period_us" respectively) configurable as well. + +The constraint on the period is that a subgroup must have a smaller or +equal period to its parent. But realistically its not very useful _yet_ +as its prone to starvation without deadline scheduling. + +Consider two sibling groups A and B; both have 50% bandwidth, but A's +period is twice the length of B's. + +* group A: period=100000us, runtime=10000us + - this runs for 0.01s once every 0.1s + +* group B: period= 50000us, runtime=10000us + - this runs for 0.01s twice every 0.1s (or once every 0.05 sec). + +This means that currently a while (1) loop in A will run for the full period of +B and can starve B's tasks (assuming they are of lower priority) for a whole +period. + +The next project will be SCHED_EDF (Earliest Deadline First scheduling) to bring +full deadline scheduling to the linux kernel. Deadline scheduling the above +groups and treating end of the period as a deadline will ensure that they both +get their allocated time. + +Implementing SCHED_EDF might take a while to complete.

Wysocki" Date: Wed, 12 Mar 2008 00:57:22 +0100 Subject: PM: Handle device registrations during suspend/resume Modify the PM core to protect its data structures, specifically the dpm_active list, from being corrupted if a child of the currently suspending device is registered concurrently with its ->suspend() callback. In that case, since the new device (the child) is added to dpm_active after its parent, the PM core will attempt to suspend it after the parent, which is wrong. Introduce a new member of struct dev_pm_info, called 'sleeping', and use it to check if the parent of the device being added to dpm_active has been suspended, in which case the device registration fails. Also, use 'sleeping' for checking if the ordering of devices on dpm_active is correct. Introduce variable 'all_sleeping' that will be set to 'true' once all devices have been suspended and make new device registrations fail until 'all_sleeping' is reset to 'false', in order to avoid having unsuspended devices around while the system is going into a sleep state. Remove pm_sleep_rwsem which is not necessary any more. Special thanks to Alan Stern for discussions and suggestions that lead to the creation of this patch. Signed-off-by: Rafael J.

The usual set of data exposed is: # for a in `find /sys/firmware/ibft/ -type f -print`; do echo -n "$a: "; cat $a; done /sys/firmware/ibft/target0/target-name: iqn.2007.com.intel-sbx44:storage-10gb /sys/firmware/ibft/target0/nic-assoc: 0 /sys/firmware/ibft/target0/chap-type: 0 /sys/firmware/ibft/target0/lun: 00000000 /sys/firmware/ibft/target0/port: 3260 /sys/firmware/ibft/target0/ip-addr: 192.168.79.116 /sys/firmware/ibft/target0/flags: 3 /sys/firmware/ibft/target0/index: 0 /sys/firmware/ibft/ethernet0/mac: 00:11:25:9d:8b:01 /sys/firmware/ibft/ethernet0/vlan: 0 /sys/firmware/ibft/ethernet0/gateway: 192.168.79.254 /sys/firmware/ibft/ethernet0/origin: 0 /sys/firmware/ibft/ethernet0/subnet-mask: 255.255.252.0 /sys/firmware/ibft/ethernet0/ip-addr: 192.168.77.41 /sys/firmware/ibft/ethernet0/flags: 7 /sys/firmware/ibft/ethernet0/index: 0 /sys/firmware/ibft/initiator/initiator-name: iqn.2007-07.com:konrad.initiator /sys/firmware/ibft/initiator/flags: 3 /sys/firmware/ibft/initiator/index: 0 For full details of the IBFT structure please take a look at: ftp://ftp.software.ibm.com/systems/support/system_x_pdf/ibm_iscsi_boot_firmware_table_v1.02.pdf [akpm@linux-foundation.org: fix build] Signed-off-by: Konrad Rzeszutek Cc: Mike Christie Cc: Peter Jones Cc: James Bottomley Cc: Ingo Molnar Cc: Thomas Gleixner Signed-off-by: Andrew Morton Signed-off-by: Greg Kroah-Hartman --- Documentation/ABI/testing/sysfs-ibft | 23 + arch/x86/kernel/setup_32.c | 3 + arch/x86/kernel/setup_64.c | 4 + drivers/firmware/Kconfig | 20 + drivers/firmware/Makefile | 2 + drivers/firmware/iscsi_ibft.c | 982 +++++++++++++++++++++++++++++++++++ drivers/firmware/iscsi_ibft_find.c | 84 +++ include/linux/iscsi_ibft.h | 50 ++ 8 files changed, 1168 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-ibft create mode 100644 drivers/firmware/iscsi_ibft.c create mode 100644 drivers/firmware/iscsi_ibft_find.c create mode 100644 include/linux/iscsi_ibft.h (limited to 'Documentation') diff --git a/Documentation/ABI/testing/sysfs-ibft b/Documentation/ABI/testing/sysfs-ibft new file mode 100644 index 000000000000..c2b7d1154bec --- /dev/null +++ b/Documentation/ABI/testing/sysfs-ibft @@ -0,0 +1,23 @@ +What: /sys/firmware/ibft/initiator +Date: November 2007 +Contact: Konrad Rzeszutek +Description: The /sys/firmware/ibft/initiator directory will contain + files that expose the iSCSI Boot Firmware Table initiator data. + Usually this contains the Initiator name. + +What: /sys/firmware/ibft/targetX +Date: November 2007 +Contact: Konrad Rzeszutek +Description: The /sys/firmware/ibft/targetX directory will contain + files that expose the iSCSI Boot Firmware Table target data. + Usually this contains the target's IP address, boot LUN, + target name, and what NIC it is associated with.

It allows userspace to get a consistent snapshot of kernel state and consume it with incremental reads and seeks. Now, if the file position is zero the kernel assumes userspace wants to see the new value. The application for this change is to allow a userspace RAID metadata handler to check the state of an array without causing any memory allocations. Thus not causing writeback to a raid array that might be blocked waiting for userspace to take action.

Copyright 2004 Intel Corporation + +3. What is the PCI Express Port Bus Driver + +A PCI Express Port is a logical PCI-PCI Bridge structure. There +are two types of PCI Express Port: the Root Port and the Switch +Port. The Root Port originates a PCI Express link from a PCI Express +Root Complex and the Switch Port connects PCI Express links to +internal logical PCI buses. The Switch Port, which has its secondary +bus representing the switch's internal routing logic, is called the +switch's Upstream Port. The switch's Downstream Port is bridging from +switch's internal routing bus to a bus representing the downstream +PCI Express link from the PCI Express Switch. + +A PCI Express Port can provide up to four distinct functions, +referred to in this document as services, depending on its port type. +PCI Express Port's services include native hotplug support (HP), +power management event support (PME), advanced error reporting +support (AER), and virtual channel support (VC). These services may +be handled by a single complex driver or be individually distributed +and handled by corresponding service drivers. + +4. Why use the PCI Express Port Bus Driver? + +In existing Linux kernels, the Linux Device Driver Model allows a +physical device to be handled by only a single driver. The PCI +Express Port is a PCI-PCI Bridge device with multiple distinct +services. To maintain a clean and simple solution each service +may have its own software service driver. In this case several +service drivers will compete for a single PCI-PCI Bridge device. +For example, if the PCI Express Root Port native hotplug service +driver is loaded first, it claims a PCI-PCI Bridge Root Port. The +kernel therefore does not load other service drivers for that Root +Port. In other words, it is impossible to have multiple service +drivers load and run on a PCI-PCI Bridge device simultaneously +using the current driver model. + +To enable multiple service drivers running simultaneously requires +having a PCI Express Port Bus driver, which manages all populated +PCI Express Ports and distributes all provided service requests +to the corresponding service drivers as required. Some key +advantages of using the PCI Express Port Bus driver are listed below: + + - Allow multiple service drivers to run simultaneously on + a PCI-PCI Bridge Port device. + + - Allow service drivers implemented in an independent + staged approach. + + - Allow one service driver to run on multiple PCI-PCI Bridge + Port devices. + + - Manage and distribute resources of a PCI-PCI Bridge Port + device to requested service drivers. + +5. Configuring the PCI Express Port Bus Driver vs. Service Drivers + +5.1 Including the PCI Express Port Bus Driver Support into the Kernel + +Including the PCI Express Port Bus driver depends on whether the PCI +Express support is included in the kernel config. The kernel will +automatically include the PCI Express Port Bus driver as a kernel +driver when the PCI Express support is enabled in the kernel. + +5.2 Enabling Service Driver Support + +PCI device drivers are implemented based on Linux Device Driver Model. +All service drivers are PCI device drivers. As discussed above, it is +impossible to load any service driver once the kernel has loaded the +PCI Express Port Bus Driver. To meet the PCI Express Port Bus Driver +Model requires some minimal changes on existing service drivers that +imposes no impact on the functionality of existing service drivers. + +A service driver is required to use the two APIs shown below to +register its service with the PCI Express Port Bus driver (see +section 5.2.1 & 5.2.2). It is important that a service driver +initializes the pcie_port_service_driver data structure, included in +header file /include/linux/pcieport_if.h, before calling these APIs. +Failure to do so will result an identity mismatch, which prevents +the PCI Express Port Bus driver from loading a service driver. + +5.2.1 pcie_port_service_register + +int pcie_port_service_register(struct pcie_port_service_driver *new) + +This API replaces the Linux Driver Model's pci_module_init API. A +service driver should always calls pcie_port_service_register at +module init. Note that after service driver being loaded, calls +such as pci_enable_device(dev) and pci_set_master(dev) are no longer +necessary since these calls are executed by the PCI Port Bus driver. + +5.2.2 pcie_port_service_unregister + +void pcie_port_service_unregister(struct pcie_port_service_driver *new) + +pcie_port_service_unregister replaces the Linux Driver Model's +pci_unregister_driver. It's always called by service driver when a +module exits. + +5.2.3 Sample Code + +Below is sample service driver code to initialize the port service +driver data structure. + +static struct pcie_port_service_id service_id[] = { { + .vendor = PCI_ANY_ID, + .device = PCI_ANY_ID, + .port_type = PCIE_RC_PORT, + .service_type = PCIE_PORT_SERVICE_AER, + }, { /* end: all zeroes */ } +}; + +static struct pcie_port_service_driver root_aerdrv = { + .name = (char *)device_name, + .id_table = &service_id[0], + + .probe = aerdrv_load, + .remove = aerdrv_unload, + + .suspend = aerdrv_suspend, + .resume = aerdrv_resume, +}; + +Below is a sample code for registering/unregistering a service +driver. + +static int __init aerdrv_service_init(void) +{ + int retval = 0; + + retval = pcie_port_service_register(&root_aerdrv); + if (!retval) { + /* + * FIX ME + */ + } + return retval; +} + +static void __exit aerdrv_service_exit(void) +{ + pcie_port_service_unregister(&root_aerdrv); +} + +module_init(aerdrv_service_init); +module_exit(aerdrv_service_exit); + +6. Possible Resource Conflicts + +Since all service drivers of a PCI-PCI Bridge Port device are +allowed to run simultaneously, below lists a few of possible resource +conflicts with proposed solutions. + +6.1 MSI Vector Resource + +The MSI capability structure enables a device software driver to call +pci_enable_msi to request MSI based interrupts. Once MSI interrupts +are enabled on a device, it stays in this mode until a device driver +calls pci_disable_msi to disable MSI interrupts and revert back to +INTx emulation mode. Since service drivers of the same PCI-PCI Bridge +port share the same physical device, if an individual service driver +calls pci_enable_msi/pci_disable_msi it may result unpredictable +behavior. For example, two service drivers run simultaneously on the +same physical Root Port. Both service drivers call pci_enable_msi to +request MSI based interrupts. A service driver may not know whether +any other service drivers have run on this Root Port. If either one +of them calls pci_disable_msi, it puts the other service driver +in a wrong interrupt mode. + +To avoid this situation all service drivers are not permitted to +switch interrupt mode on its device. The PCI Express Port Bus driver +is responsible for determining the interrupt mode and this should be +transparent to service drivers. Service drivers need to know only +the vector IRQ assigned to the field irq of struct pcie_device, which +is passed in when the PCI Express Port Bus driver probes each service +driver. Service drivers should use (struct pcie_device*)dev->irq to +call request_irq/free_irq. In addition, the interrupt mode is stored +in the field interrupt_mode of struct pcie_device. + +6.2 MSI-X Vector Resources + +Similar to the MSI a device driver for an MSI-X capable device can +call pci_enable_msix to request MSI-X interrupts. All service drivers +are not permitted to switch interrupt mode on its device.

Some of the more advanced +chipsets are able to deal with these errors; these include PCI-E chipsets, +and the PCI-host bridges found on IBM Power4 and Power5-based pSeries +boxes. A typical action taken is to disconnect the affected device, +halting all I/O to it. The goal of a disconnection is to avoid system +corruption; for example, to halt system memory corruption due to DMA's +to "wild" addresses. Typically, a reconnection mechanism is also +offered, so that the affected PCI device(s) are reset and put back +into working condition. The reset phase requires coordination +between the affected device drivers and the PCI controller chip. +This document describes a generic API for notifying device drivers +of a bus disconnection, and then performing error recovery. +This API is currently implemented in the 2.6.16 and later kernels. + +Reporting and recovery is performed in several steps. First, when +a PCI hardware error has resulted in a bus disconnect, that event +is reported as soon as possible to all affected device drivers, +including multiple instances of a device driver on multi-function +cards. This allows device drivers to avoid deadlocking in spinloops, +waiting for some i/o-space register to change, when it never will. +It also gives the drivers a chance to defer incoming I/O as +needed. + +Next, recovery is performed in several stages. Most of the complexity +is forced by the need to handle multi-function devices, that is, +devices that have multiple device drivers associated with them. +In the first stage, each driver is allowed to indicate what type +of reset it desires, the choices being a simple re-enabling of I/O +or requesting a hard reset (a full electrical #RST of the PCI card). +If any driver requests a full reset, that is what will be done. + +After a full reset and/or a re-enabling of I/O, all drivers are +again notified, so that they may then perform any device setup/config +that may be required. After these have all completed, a final +"resume normal operations" event is sent out. + +The biggest reason for choosing a kernel-based implementation rather +than a user-space implementation was the need to deal with bus +disconnects of PCI devices attached to storage media, and, in particular, +disconnects from devices holding the root file system. If the root +file system is disconnected, a user-space mechanism would have to go +through a large number of contortions to complete recovery. Almost all +of the current Linux file systems are not tolerant of disconnection +from/reconnection to their underlying block device. By contrast, +bus errors are easy to manage in the device driver. Indeed, most +device drivers already handle very similar recovery procedures; +for example, the SCSI-generic layer already provides significant +mechanisms for dealing with SCSI bus errors and SCSI bus resets. + + +Detailed Design +--------------- +Design and implementation details below, based on a chain of +public email discussions with Ben Herrenschmidt, circa 5 April 2005. + +The error recovery API support is exposed to the driver in the form of +a structure of function pointers pointed to by a new field in struct +pci_driver. A driver that fails to provide the structure is "non-aware", +and the actual recovery steps taken are platform dependent. The +arch/powerpc implementation will simulate a PCI hotplug remove/add. + +This structure has the form: +struct pci_error_handlers +{ + int (*error_detected)(struct pci_dev *dev, enum pci_channel_state); + int (*mmio_enabled)(struct pci_dev *dev); + int (*link_reset)(struct pci_dev *dev); + int (*slot_reset)(struct pci_dev *dev); + void (*resume)(struct pci_dev *dev); +}; + +The possible channel states are: +enum pci_channel_state { + pci_channel_io_normal, /* I/O channel is in normal state */ + pci_channel_io_frozen, /* I/O to channel is blocked */ + pci_channel_io_perm_failure, /* PCI card is dead */ +}; + +Possible return values are: +enum pci_ers_result { + PCI_ERS_RESULT_NONE, /* no result/none/not supported in device driver */ + PCI_ERS_RESULT_CAN_RECOVER, /* Device driver can recover without slot reset */ + PCI_ERS_RESULT_NEED_RESET, /* Device driver wants slot to be reset. */ + PCI_ERS_RESULT_DISCONNECT, /* Device has completely failed, is unrecoverable */ + PCI_ERS_RESULT_RECOVERED, /* Device driver is fully recovered and operational */ +}; + +A driver does not have to implement all of these callbacks; however, +if it implements any, it must implement error_detected(). If a callback +is not implemented, the corresponding feature is considered unsupported. +For example, if mmio_enabled() and resume() aren't there, then it +is assumed that the driver is not doing any direct recovery and requires +a reset. If link_reset() is not implemented, the card is assumed as +not care about link resets. Typically a driver will want to know about +a slot_reset(). + +The actual steps taken by a platform to recover from a PCI error +event will be platform-dependent, but will follow the general +sequence described below. + +STEP 0: Error Event +------------------- +PCI bus error is detect by the PCI hardware. On powerpc, the slot +is isolated, in that all I/O is blocked: all reads return 0xffffffff, +all writes are ignored. + + +STEP 1: Notification +-------------------- +Platform calls the error_detected() callback on every instance of +every driver affected by the error. + +At this point, the device might not be accessible anymore, depending on +the platform (the slot will be isolated on powerpc). The driver may +already have "noticed" the error because of a failing I/O, but this +is the proper "synchronization point", that is, it gives the driver +a chance to cleanup, waiting for pending stuff (timers, whatever, etc...) +to complete; it can take semaphores, schedule, etc... everything but +touch the device. Within this function and after it returns, the driver +shouldn't do any new IOs. Called in task context. This is sort of a +"quiesce" point. See note about interrupts at the end of this doc. + +All drivers participating in this system must implement this call. +The driver must return one of the following result codes: + - PCI_ERS_RESULT_CAN_RECOVER: + Driver returns this if it thinks it might be able to recover + the HW by just banging IOs or if it wants to be given + a chance to extract some diagnostic information (see + mmio_enable, below). + - PCI_ERS_RESULT_NEED_RESET: + Driver returns this if it can't recover without a hard + slot reset. + - PCI_ERS_RESULT_DISCONNECT: + Driver returns this if it doesn't want to recover at all. + +The next step taken will depend on the result codes returned by the +drivers. + +If all drivers on the segment/slot return PCI_ERS_RESULT_CAN_RECOVER, +then the platform should re-enable IOs on the slot (or do nothing in +particular, if the platform doesn't isolate slots), and recovery +proceeds to STEP 2 (MMIO Enable). + +If any driver requested a slot reset (by returning PCI_ERS_RESULT_NEED_RESET), +then recovery proceeds to STEP 4 (Slot Reset). + +If the platform is unable to recover the slot, the next step +is STEP 6 (Permanent Failure). + +>>> The current powerpc implementation assumes that a device driver will +>>> *not* schedule or semaphore in this routine; the current powerpc +>>> implementation uses one kernel thread to notify all devices; +>>> thus, if one device sleeps/schedules, all devices are affected. +>>> Doing better requires complex multi-threaded logic in the error +>>> recovery implementation (e.g. waiting for all notification threads +>>> to "join" before proceeding with recovery.)

There doesn't seem to be any other +>>> way of stopping a device driver that insists on spinning on I/O. + +STEP 2: MMIO Enabled +------------------- +The platform re-enables MMIO to the device (but typically not the +DMA), and then calls the mmio_enabled() callback on all affected +device drivers. + +This is the "early recovery" call. IOs are allowed again, but DMA is +not (hrm... to be discussed, I prefer not), with some restrictions. This +is NOT a callback for the driver to start operations again, only to +peek/poke at the device, extract diagnostic information, if any, and +eventually do things like trigger a device local reset or some such, +but not restart operations. This is callback is made if all drivers on +a segment agree that they can try to recover and if no automatic link reset +was performed by the HW. If the platform can't just re-enable IOs without +a slot reset or a link reset, it wont call this callback, and instead +will have gone directly to STEP 3 (Link Reset) or STEP 4 (Slot Reset) + +>>> The following is proposed; no platform implements this yet: +>>> Proposal: All I/O's should be done _synchronously_ from within +>>> this callback, errors triggered by them will be returned via +>>> the normal pci_check_whatever() API, no new error_detected() +>>> callback will be issued due to an error happening here. However, +>>> such an error might cause IOs to be re-blocked for the whole +>>> segment, and thus invalidate the recovery that other devices +>>> on the same segment might have done, forcing the whole segment +>>> into one of the next states, that is, link reset or slot reset. + +The driver should return one of the following result codes: + - PCI_ERS_RESULT_RECOVERED + Driver returns this if it thinks the device is fully + functional and thinks it is ready to start + normal driver operations again. There is no + guarantee that the driver will actually be + allowed to proceed, as another driver on the + same segment might have failed and thus triggered a + slot reset on platforms that support it. + + - PCI_ERS_RESULT_NEED_RESET + Driver returns this if it thinks the device is not + recoverable in it's current state and it needs a slot + reset to proceed. + + - PCI_ERS_RESULT_DISCONNECT + Same as above. Total failure, no recovery even after + reset driver dead. (To be defined more precisely) + +The next step taken depends on the results returned by the drivers. +If all drivers returned PCI_ERS_RESULT_RECOVERED, then the platform +proceeds to either STEP3 (Link Reset) or to STEP 5 (Resume Operations). + +If any driver returned PCI_ERS_RESULT_NEED_RESET, then the platform +proceeds to STEP 4 (Slot Reset) + +>>> The current powerpc implementation does not implement this callback. + + +STEP 3: Link Reset +------------------ +The platform resets the link, and then calls the link_reset() callback +on all affected device drivers. This is a PCI-Express specific state +and is done whenever a non-fatal error has been detected that can be +"solved" by resetting the link. This call informs the driver of the +reset and the driver should check to see if the device appears to be +in working condition. + +The driver is not supposed to restart normal driver I/O operations +at this point. It should limit itself to "probing" the device to +check it's recoverability status. If all is right, then the platform +will call resume() once all drivers have ack'd link_reset(). + + Result codes: + (identical to STEP 3 (MMIO Enabled) + +The platform then proceeds to either STEP 4 (Slot Reset) or STEP 5 +(Resume Operations). + +>>> The current powerpc implementation does not implement this callback. + + +STEP 4: Slot Reset +------------------ +The platform performs a soft or hard reset of the device, and then +calls the slot_reset() callback. + +A soft reset consists of asserting the adapter #RST line and then +restoring the PCI BAR's and PCI configuration header to a state +that is equivalent to what it would be after a fresh system +power-on followed by power-on BIOS/system firmware initialization. +If the platform supports PCI hotplug, then the reset might be +performed by toggling the slot electrical power off/on. + +It is important for the platform to restore the PCI config space +to the "fresh poweron" state, rather than the "last state". After +a slot reset, the device driver will almost always use its standard +device initialization routines, and an unusual config space setup +may result in hung devices, kernel panics, or silent data corruption. + +This call gives drivers the chance to re-initialize the hardware +(re-download firmware, etc.). At this point, the driver may assume +that he card is in a fresh state and is fully functional. In +particular, interrupt generation should work normally. + +Drivers should not yet restart normal I/O processing operations +at this point. If all device drivers report success on this +callback, the platform will call resume() to complete the sequence, +and let the driver restart normal I/O processing. + +A driver can still return a critical failure for this function if +it can't get the device operational after reset. If the platform +previously tried a soft reset, it might now try a hard reset (power +cycle) and then call slot_reset() again. It the device still can't +be recovered, there is nothing more that can be done; the platform +will typically report a "permanent failure" in such a case. The +device will be considered "dead" in this case. + +Drivers for multi-function cards will need to coordinate among +themselves as to which driver instance will perform any "one-shot" +or global device initialization. For example, the Symbios sym53cxx2 +driver performs device init only from PCI function 0: + ++ if (PCI_FUNC(pdev->devfn) == 0) ++ sym_reset_scsi_bus(np, 0); + + Result codes: + - PCI_ERS_RESULT_DISCONNECT + Same as above. + +Platform proceeds either to STEP 5 (Resume Operations) or STEP 6 (Permanent +Failure). + +>>> The current powerpc implementation does not currently try a +>>> power-cycle reset if the driver returned PCI_ERS_RESULT_DISCONNECT. +>>> However, it probably should. + + +STEP 5: Resume Operations +------------------------- +The platform will call the resume() callback on all affected device +drivers if all drivers on the segment have returned +PCI_ERS_RESULT_RECOVERED from one of the 3 previous callbacks. +The goal of this callback is to tell the driver to restart activity, +that everything is back and running. This callback does not return +a result code. + +At this point, if a new error happens, the platform will restart +a new error recovery sequence. + +STEP 6: Permanent Failure +------------------------- +A "permanent failure" has occurred, and the platform cannot recover +the device. The platform will call error_detected() with a +pci_channel_state value of pci_channel_io_perm_failure. + +The device driver should, at this point, assume the worst. It should +cancel all pending I/O, refuse all new I/O, returning -EIO to +higher layers. The device driver should then clean up all of its +memory and remove itself from kernel operations, much as it would +during system shutdown. + +The platform will typically notify the system operator of the +permanent failure in some way. If the device is hotplug-capable, +the operator will probably want to remove and replace the device. +Note, however, not all failures are truly "permanent". Some are +caused by over-heating, some by a poorly seated card. Many +PCI error events are caused by software bugs, e.g. DMA's to +wild addresses or bogus split transactions due to programming +errors. See the discussion in powerpc/eeh-pci-error-recovery.txt +for additional detail on real-life experience of the causes of +software errors. + + +Conclusion; General Remarks +--------------------------- +The way those callbacks are called is platform policy. A platform with +no slot reset capability may want to just "ignore" drivers that can't +recover (disconnect them) and try to let other cards on the same segment +recover. Keep in mind that in most real life cases, though, there will +be only one driver per segment. + +Now, a note about interrupts. If you get an interrupt and your +device is dead or has been isolated, there is a problem :) +The current policy is to turn this into a platform policy. +That is, the recovery API only requires that: + + - There is no guarantee that interrupt delivery can proceed from any +device on the segment starting from the error detection and until the +resume callback is sent, at which point interrupts are expected to be +fully operational. + + - There is no guarantee that interrupt delivery is stopped, that is, +a driver that gets an interrupt after detecting an error, or that detects +an error within the interrupt handler such that it prevents proper +ack'ing of the interrupt (and thus removal of the source) should just +return IRQ_NOTHANDLED. It's up to the platform to deal with that +condition, typically by masking the IRQ source during the duration of +the error handling. It is expected that the platform "knows" which +interrupts are routed to error-management capable slots and can deal +with temporarily disabling that IRQ number during error processing (this +isn't terribly complex). That means some IRQ latency for other devices +sharing the interrupt, but there is simply no other way. High end +platforms aren't supposed to share interrupts between many devices +anyway :) + +>>> Implementation details for the powerpc platform are discussed in +>>> the file Documentation/powerpc/eeh-pci-error-recovery.txt + +>>> As of this writing, there are six device drivers with patches +>>> implementing error recovery.

Structure of PCI drivers +~~~~~~~~~~~~~~~~~~~~~~~~~~~ +PCI drivers "discover" PCI devices in a system via pci_register_driver(). +Actually, it's the other way around. When the PCI generic code discovers +a new device, the driver with a matching "description" will be notified. +Details on this below. + +pci_register_driver() leaves most of the probing for devices to +the PCI layer and supports online insertion/removal of devices [thus +supporting hot-pluggable PCI, CardBus, and Express-Card in a single driver]. +pci_register_driver() call requires passing in a table of function +pointers and thus dictates the high level structure of a driver. + +Once the driver knows about a PCI device and takes ownership, the +driver generally needs to perform the following initialization: + + Enable the device + Request MMIO/IOP resources + Set the DMA mask size (for both coherent and streaming DMA) + Allocate and initialize shared control data (pci_allocate_coherent()) + Access device configuration space (if needed) + Register IRQ handler (request_irq()) + Initialize non-PCI (i.e. LAN/SCSI/etc parts of the chip) + Enable DMA/processing engines + +When done using the device, and perhaps the module needs to be unloaded, +the driver needs to take the follow steps: + Disable the device from generating IRQs + Release the IRQ (free_irq()) + Stop all DMA activity + Release DMA buffers (both streaming and coherent) + Unregister from other subsystems (e.g. scsi or netdev) + Release MMIO/IOP resources + Disable the device + +Most of these topics are covered in the following sections. +For the rest look at LDD3 or . + +If the PCI subsystem is not configured (CONFIG_PCI is not set), most of +the PCI functions described below are defined as inline functions either +completely empty or just returning an appropriate error codes to avoid +lots of ifdefs in the drivers. + + + +1. pci_register_driver() call +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +PCI device drivers call pci_register_driver() during their +initialization with a pointer to a structure describing the driver +(struct pci_driver): + + field name Description + ---------- ------------------------------------------------------ + id_table Pointer to table of device ID's the driver is + interested in. Most drivers should export this + table using MODULE_DEVICE_TABLE(pci,...). + + probe This probing function gets called (during execution + of pci_register_driver() for already existing + devices or later if a new device gets inserted) for + all PCI devices which match the ID table and are not + "owned" by the other drivers yet. This function gets + passed a "struct pci_dev *" for each device whose + entry in the ID table matches the device. The probe + function returns zero when the driver chooses to + take "ownership" of the device or an error code + (negative number) otherwise. + The probe function always gets called from process + context, so it can sleep. + + remove The remove() function gets called whenever a device + being handled by this driver is removed (either during + deregistration of the driver or when it's manually + pulled out of a hot-pluggable slot). + The remove function always gets called from process + context, so it can sleep. + + suspend Put device into low power state. + suspend_late Put device into low power state. + + resume_early Wake device from low power state. + resume Wake device from low power state. + + (Please see Documentation/power/pci.txt for descriptions + of PCI Power Management and the related functions.) + + shutdown Hook into reboot_notifier_list (kernel/sys.c). + Intended to stop any idling DMA operations. + Useful for enabling wake-on-lan (NIC) or changing + the power state of a device before reboot. + e.g. drivers/net/e100.c. + + err_handler See Documentation/PCI/pci-error-recovery.txt + + +The ID table is an array of struct pci_device_id entries ending with an +all-zero entry; use of the macro DEFINE_PCI_DEVICE_TABLE is the preferred +method of declaring the table. Each entry consists of: + + vendor,device Vendor and device ID to match (or PCI_ANY_ID) + + subvendor, Subsystem vendor and device ID to match (or PCI_ANY_ID) + subdevice, + + class Device class, subclass, and "interface" to match. + See Appendix D of the PCI Local Bus Spec or + include/linux/pci_ids.h for a full list of classes. + Most drivers do not need to specify class/class_mask + as vendor/device is normally sufficient. + + class_mask limit which sub-fields of the class field are compared. + See drivers/scsi/sym53c8xx_2/ for example of usage. + + driver_data Data private to the driver. + Most drivers don't need to use driver_data field. + Best practice is to use driver_data as an index + into a static list of equivalent device types, + instead of using it as a pointer. + + +Most drivers only need PCI_DEVICE() or PCI_DEVICE_CLASS() to set up +a pci_device_id table. + +New PCI IDs may be added to a device driver pci_ids table at runtime +as shown below: + +echo "vendor device subvendor subdevice class class_mask driver_data" > \ +/sys/bus/pci/drivers/{driver}/new_id + +All fields are passed in as hexadecimal values (no leading 0x). +The vendor and device fields are mandatory, the others are optional. Users +need pass only as many optional fields as necessary: + o subvendor and subdevice fields default to PCI_ANY_ID (FFFFFFFF) + o class and classmask fields default to 0 + o driver_data defaults to 0UL. + +Once added, the driver probe routine will be invoked for any unclaimed +PCI devices listed in its (newly updated) pci_ids list. + +When the driver exits, it just calls pci_unregister_driver() and the PCI layer +automatically calls the remove hook for all devices handled by the driver. + + +1.1 "Attributes" for driver functions/data + +Please mark the initialization and cleanup functions where appropriate +(the corresponding macros are defined in ): + + __init Initialization code. Thrown away after the driver + initializes. + __exit Exit code. Ignored for non-modular drivers. + + + __devinit Device initialization code. + Identical to __init if the kernel is not compiled + with CONFIG_HOTPLUG, normal function otherwise. + __devexit The same for __exit. + +Tips on when/where to use the above attributes: + o The module_init()/module_exit() functions (and all + initialization functions called _only_ from these) + should be marked __init/__exit. + + o Do not mark the struct pci_driver. + + o The ID table array should be marked __devinitconst; this is done + automatically if the table is declared with DEFINE_PCI_DEVICE_TABLE(). + + o The probe() and remove() functions should be marked __devinit + and __devexit respectively.

For an example, see drivers/net/tg3.c. + + o Do NOT mark a function if you are not sure which mark to use. + Better to not mark the function than mark the function wrong. + + + +2. How to find PCI devices manually +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +PCI drivers should have a really good reason for not using the +pci_register_driver() interface to search for PCI devices. +The main reason PCI devices are controlled by multiple drivers +is because one PCI device implements several different HW services. +E.g. combined serial/parallel port/floppy controller. + +A manual search may be performed using the following constructs: + +Searching by vendor and device ID: + + struct pci_dev *dev = NULL; + while (dev = pci_get_device(VENDOR_ID, DEVICE_ID, dev)) + configure_device(dev); + +Searching by class ID (iterate in a similar way): + + pci_get_class(CLASS_ID, dev) + +Searching by both vendor/device and subsystem vendor/device ID: + + pci_get_subsys(VENDOR_ID,DEVICE_ID, SUBSYS_VENDOR_ID, SUBSYS_DEVICE_ID, dev). + +You can use the constant PCI_ANY_ID as a wildcard replacement for +VENDOR_ID or DEVICE_ID. This allows searching for any device from a +specific vendor, for example. + +These functions are hotplug-safe. They increment the reference count on +the pci_dev that they return. You must eventually (possibly at module unload) +decrement the reference count on these devices by calling pci_dev_put(). + + + +3. Device Initialization Steps +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +As noted in the introduction, most PCI drivers need the following steps +for device initialization: + + Enable the device + Request MMIO/IOP resources + Set the DMA mask size (for both coherent and streaming DMA) + Allocate and initialize shared control data (pci_allocate_coherent()) + Access device configuration space (if needed) + Register IRQ handler (request_irq()) + Initialize non-PCI (i.e. LAN/SCSI/etc parts of the chip) + Enable DMA/processing engines. + +The driver can access PCI config space registers at any time. +(Well, almost. When running BIST, config space can go away...but +that will just result in a PCI Bus Master Abort and config reads +will return garbage). + + +3.1 Enable the PCI device +~~~~~~~~~~~~~~~~~~~~~~~~~ +Before touching any device registers, the driver needs to enable +the PCI device by calling pci_enable_device(). This will: + o wake up the device if it was in suspended state, + o allocate I/O and memory regions of the device (if BIOS did not), + o allocate an IRQ (if BIOS did not). + +NOTE: pci_enable_device() can fail! Check the return value. + +[ OS BUG: we don't check resource allocations before enabling those + resources. The sequence would make more sense if we called + pci_request_resources() before calling pci_enable_device(). + Currently, the device drivers can't detect the bug when when two + devices have been allocated the same range. This is not a common + problem and unlikely to get fixed soon. + + This has been discussed before but not changed as of 2.6.19: + http://lkml.org/lkml/2006/3/2/194 +] + +pci_set_master() will enable DMA by setting the bus master bit +in the PCI_COMMAND register. It also fixes the latency timer value if +it's set to something bogus by the BIOS. + +If the PCI device can use the PCI Memory-Write-Invalidate transaction, +call pci_set_mwi(). This enables the PCI_COMMAND bit for Mem-Wr-Inval +and also ensures that the cache line size register is set correctly. +Check the return value of pci_set_mwi() as not all architectures +or chip-sets may support Memory-Write-Invalidate. Alternatively, +if Mem-Wr-Inval would be nice to have but is not required, call +pci_try_set_mwi() to have the system do its best effort at enabling +Mem-Wr-Inval. + + +3.2 Request MMIO/IOP resources +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Memory (MMIO), and I/O port addresses should NOT be read directly +from the PCI device config space. Use the values in the pci_dev structure +as the PCI "bus address" might have been remapped to a "host physical" +address by the arch/chip-set specific kernel support. + +See Documentation/IO-mapping.txt for how to access device registers +or device memory. + +The device driver needs to call pci_request_region() to verify +no other device is already using the same address resource. +Conversely, drivers should call pci_release_region() AFTER +calling pci_disable_device(). +The idea is to prevent two devices colliding on the same address range. + +[ See OS BUG comment above. Currently (2.6.19), The driver can only + determine MMIO and IO Port resource availability _after_ calling + pci_enable_device(). ] + +Generic flavors of pci_request_region() are request_mem_region() +(for MMIO ranges) and request_region() (for IO Port ranges). +Use these for address resources that are not described by "normal" PCI +BARs. + +Also see pci_request_selected_regions() below. + + +3.3 Set the DMA mask size +~~~~~~~~~~~~~~~~~~~~~~~~~ +[ If anything below doesn't make sense, please refer to + Documentation/DMA-API.txt. This section is just a reminder that + drivers need to indicate DMA capabilities of the device and is not + an authoritative source for DMA interfaces. ] + +While all drivers should explicitly indicate the DMA capability +(e.g. 32 or 64 bit) of the PCI bus master, devices with more than +32-bit bus master capability for streaming data need the driver +to "register" this capability by calling pci_set_dma_mask() with +appropriate parameters. In general this allows more efficient DMA +on systems where System RAM exists above 4G _physical_ address. + +Drivers for all PCI-X and PCIe compliant devices must call +pci_set_dma_mask() as they are 64-bit DMA devices. + +Similarly, drivers must also "register" this capability if the device +can directly address "consistent memory" in System RAM above 4G physical +address by calling pci_set_consistent_dma_mask(). +Again, this includes drivers for all PCI-X and PCIe compliant devices. +Many 64-bit "PCI" devices (before PCI-X) and some PCI-X devices are +64-bit DMA capable for payload ("streaming") data but not control +("consistent") data. + + +3.4 Setup shared control data +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Once the DMA masks are set, the driver can allocate "consistent" (a.k.a. shared) +memory. See Documentation/DMA-API.txt for a full description of +the DMA APIs. This section is just a reminder that it needs to be done +before enabling DMA on the device. + + +3.5 Initialize device registers +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Some drivers will need specific "capability" fields programmed +or other "vendor specific" register initialized or reset. +E.g. clearing pending interrupts. + + +3.6 Register IRQ handler +~~~~~~~~~~~~~~~~~~~~~~~~ +While calling request_irq() is the last step described here, +this is often just another intermediate step to initialize a device. +This step can often be deferred until the device is opened for use. + +All interrupt handlers for IRQ lines should be registered with IRQF_SHARED +and use the devid to map IRQs to devices (remember that all PCI IRQ lines +can be shared). + +request_irq() will associate an interrupt handler and device handle +with an interrupt number. Historically interrupt numbers represent +IRQ lines which run from the PCI device to the Interrupt controller. +With MSI and MSI-X (more below) the interrupt number is a CPU "vector". + +request_irq() also enables the interrupt. Make sure the device is +quiesced and does not have any interrupts pending before registering +the interrupt handler. + +MSI and MSI-X are PCI capabilities. Both are "Message Signaled Interrupts" +which deliver interrupts to the CPU via a DMA write to a Local APIC. +The fundamental difference between MSI and MSI-X is how multiple +"vectors" get allocated. MSI requires contiguous blocks of vectors +while MSI-X can allocate several individual ones. + +MSI capability can be enabled by calling pci_enable_msi() or +pci_enable_msix() before calling request_irq(). This causes +the PCI support to program CPU vector data into the PCI device +capability registers. + +If your PCI device supports both, try to enable MSI-X first. +Only one can be enabled at a time. Many architectures, chip-sets, +or BIOSes do NOT support MSI or MSI-X and the call to pci_enable_msi/msix +will fail. This is important to note since many drivers have +two (or more) interrupt handlers: one for MSI/MSI-X and another for IRQs. +They choose which handler to register with request_irq() based on the +return value from pci_enable_msi/msix(). + +There are (at least) two really good reasons for using MSI: +1) MSI is an exclusive interrupt vector by definition. + This means the interrupt handler doesn't have to verify + its device caused the interrupt. + +2) MSI avoids DMA/IRQ race conditions. DMA to host memory is guaranteed + to be visible to the host CPU(s) when the MSI is delivered. This + is important for both data coherency and avoiding stale control data. + This guarantee allows the driver to omit MMIO reads to flush + the DMA stream. + +See drivers/infiniband/hw/mthca/ or drivers/net/tg3.c for examples +of MSI/MSI-X usage. + + + +4. PCI device shutdown +~~~~~~~~~~~~~~~~~~~~~~~ + +When a PCI device driver is being unloaded, most of the following +steps need to be performed: + + Disable the device from generating IRQs + Release the IRQ (free_irq()) + Stop all DMA activity + Release DMA buffers (both streaming and consistent) + Unregister from other subsystems (e.g. scsi or netdev) + Disable device from responding to MMIO/IO Port addresses + Release MMIO/IO Port resource(s) + + +4.1 Stop IRQs on the device +~~~~~~~~~~~~~~~~~~~~~~~~~~~ +How to do this is chip/device specific. If it's not done, it opens +the possibility of a "screaming interrupt" if (and only if) +the IRQ is shared with another device. + +When the shared IRQ handler is "unhooked", the remaining devices +using the same IRQ line will still need the IRQ enabled. Thus if the +"unhooked" device asserts IRQ line, the system will respond assuming +it was one of the remaining devices asserted the IRQ line. Since none +of the other devices will handle the IRQ, the system will "hang" until +it decides the IRQ isn't going to get handled and masks the IRQ (100,000 +iterations later). Once the shared IRQ is masked, the remaining devices +will stop functioning properly. Not a nice situation. + +This is another reason to use MSI or MSI-X if it's available. +MSI and MSI-X are defined to be exclusive interrupts and thus +are not susceptible to the "screaming interrupt" problem. + + +4.2 Release the IRQ +~~~~~~~~~~~~~~~~~~~ +Once the device is quiesced (no more IRQs), one can call free_irq(). +This function will return control once any pending IRQs are handled, +"unhook" the drivers IRQ handler from that IRQ, and finally release +the IRQ if no one else is using it. + + +4.3 Stop all DMA activity +~~~~~~~~~~~~~~~~~~~~~~~~~ +It's extremely important to stop all DMA operations BEFORE attempting +to deallocate DMA control data. Failure to do so can result in memory +corruption, hangs, and on some chip-sets a hard crash. + +Stopping DMA after stopping the IRQs can avoid races where the +IRQ handler might restart DMA engines. + +While this step sounds obvious and trivial, several "mature" drivers +didn't get this step right in the past. + + +4.4 Release DMA buffers +~~~~~~~~~~~~~~~~~~~~~~~ +Once DMA is stopped, clean up streaming DMA first. +I.e. unmap data buffers and return buffers to "upstream" +owners if there is one. + +Then clean up "consistent" buffers which contain the control data. + +See Documentation/DMA-API.txt for details on unmapping interfaces. + + +4.5 Unregister from other subsystems +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Most low level PCI device drivers support some other subsystem +like USB, ALSA, SCSI, NetDev, Infiniband, etc. Make sure your +driver isn't losing resources from that other subsystem. +If this happens, typically the symptom is an Oops (panic) when +the subsystem attempts to call into a driver that has been unloaded. + + +4.6 Disable Device from responding to MMIO/IO Port addresses +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +io_unmap() MMIO or IO Port resources and then call pci_disable_device(). +This is the symmetric opposite of pci_enable_device(). +Do not access device registers after calling pci_disable_device(). + + +4.7 Release MMIO/IO Port Resource(s) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Call pci_release_region() to mark the MMIO or IO Port range as available. +Failure to do so usually results in the inability to reload the driver. + + + +5. How to access PCI config space +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +You can use pci_(read|write)_config_(byte|word|dword) to access the config +space of a device represented by struct pci_dev *. All these functions return 0 +when successful or an error code (PCIBIOS_...) which can be translated to a text +string by pcibios_strerror. Most drivers expect that accesses to valid PCI +devices don't fail. + +If you don't have a struct pci_dev available, you can call +pci_bus_(read|write)_config_(byte|word|dword) to access a given device +and function on that bus. + +If you access fields in the standard portion of the config header, please +use symbolic names of locations and bits declared in . + +If you need to access Extended PCI Capability registers, just call +pci_find_capability() for the particular capability and it will find the +corresponding register block for you. + + + +6. Other interesting functions +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +pci_find_slot() Find pci_dev corresponding to given bus and + slot numbers. +pci_set_power_state() Set PCI Power Management state (0=D0 ... 3=D3) +pci_find_capability() Find specified capability in device's capability + list. +pci_resource_start() Returns bus start address for a given PCI region +pci_resource_end() Returns bus end address for a given PCI region +pci_resource_len() Returns the byte length of a PCI region +pci_set_drvdata() Set private driver data pointer for a pci_dev +pci_get_drvdata() Return private driver data pointer for a pci_dev +pci_set_mwi() Enable Memory-Write-Invalidate transactions. +pci_clear_mwi() Disable Memory-Write-Invalidate transactions. + + + +7. Miscellaneous hints +~~~~~~~~~~~~~~~~~~~~~~ + +When displaying PCI device names to the user (for example when a driver wants +to tell the user what card has it found), please use pci_name(pci_dev). + +Always refer to the PCI devices by a pointer to the pci_dev structure. +All PCI layer functions use this identification and it's the only +reasonable one. Don't use bus/slot/function numbers except for very +special purposes -- on systems with multiple primary buses their semantics +can be pretty complex. + +Don't try to turn on Fast Back to Back writes in your driver. All devices +on the bus need to be capable of doing it, so this is something which needs +to be handled by platform and generic code, not individual drivers. + + + +8. Vendor and device identifications +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +One is not not required to add new device ids to include/linux/pci_ids.h. +Please add PCI_VENDOR_ID_xxx for vendors and a hex constant for device ids. + +PCI_VENDOR_ID_xxx constants are re-used. The device ids are arbitrary +hex numbers (vendor controlled) and normally used only in a single +location, the pci_device_id table. + +Please DO submit new vendor/device ids to pciids.sourceforge.net project. + + + +9. Obsolete functions +~~~~~~~~~~~~~~~~~~~~~ + +There are several functions which you might come across when trying to +port an old driver to the new PCI interface. They are no longer present +in the kernel as they aren't compatible with hotplug or PCI domains or +having sane locking. + +pci_find_device() Superseded by pci_get_device() +pci_find_subsys() Superseded by pci_get_subsys() +pci_find_slot() Superseded by pci_get_slot() + + +The alternative is the traditional PCI device driver that walks PCI +device lists. This is still possible but discouraged. + + + +10. MMIO Space and "Write Posting" +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Converting a driver from using I/O Port space to using MMIO space +often requires some additional changes. Specifically, "write posting" +needs to be handled. Many drivers (e.g. tg3, acenic, sym53c8xx_2) +already do this. I/O Port space guarantees write transactions reach the PCI +device before the CPU can continue. Writes to MMIO space allow the CPU +to continue before the transaction reaches the PCI device. HW weenies +call this "Write Posting" because the write completion is "posted" to +the CPU before the transaction has reached its destination. + +Thus, timing sensitive code should add readl() where the CPU is +expected to wait before doing other work. The classic "bit banging" +sequence works fine for I/O Port space: + + for (i = 8; --i; val >>= 1) { + outb(val & 1, ioport_reg); /* write bit */ + udelay(10); + } + +The same sequence for MMIO space should be: + + for (i = 8; --i; val >>= 1) { + writeb(val & 1, mmio_reg); /* write bit */ + readb(safe_mmio_reg); /* flush posted write */ + udelay(10); + } + +It is important that "safe_mmio_reg" not have any side effects that +interferes with the correct operation of the device. + +Another case to watch out for is when resetting a PCI device. Use PCI +Configuration space reads to flush the writel(). This will gracefully +handle the PCI master abort on all platforms if the PCI device is +expected to not respond to a readl(). Most x86 platforms will allow +MMIO reads to master abort (a.k.a. "Soft Fail") and return garbage +(e.g. ~0). But many RISC platforms will crash (a.k.a."Hard Fail"). + diff --git a/Documentation/PCI/pcieaer-howto.txt b/Documentation/PCI/pcieaer-howto.txt new file mode 100644 index 000000000000..16c251230c82 --- /dev/null +++ b/Documentation/PCI/pcieaer-howto.txt @@ -0,0 +1,253 @@ + The PCI Express Advanced Error Reporting Driver Guide HOWTO + T.

PCI Express +defines two error reporting paradigms: the baseline capability and +the Advanced Error Reporting capability. The baseline capability is +required of all PCI Express components providing a minimum defined +set of error reporting requirements. Advanced Error Reporting +capability is implemented with a PCI Express advanced error reporting +extended capability structure providing more robust error reporting. + +The PCI Express AER driver provides the infrastructure to support PCI +Express Advanced Error Reporting capability. The PCI Express AER +driver provides three basic functions: + +- Gathers the comprehensive error information if errors occurred. +- Reports error to the users. +- Performs error recovery actions. + +AER driver only attaches root ports which support PCI-Express AER +capability. + + +2. User Guide + +2.1 Include the PCI Express AER Root Driver into the Linux Kernel + +The PCI Express AER Root driver is a Root Port service driver attached +to the PCI Express Port Bus driver. If a user wants to use it, the driver +has to be compiled. Option CONFIG_PCIEAER supports this capability. It +depends on CONFIG_PCIEPORTBUS, so pls. set CONFIG_PCIEPORTBUS=y and +CONFIG_PCIEAER = y. + +2.2 Load PCI Express AER Root Driver +There is a case where a system has AER support in BIOS. Enabling the AER +Root driver and having AER support in BIOS may result unpredictable +behavior. To avoid this conflict, a successful load of the AER Root driver +requires ACPI _OSC support in the BIOS to allow the AER Root driver to +request for native control of AER. See the PCI FW 3.0 Specification for +details regarding OSC usage. Currently, lots of firmwares don't provide +_OSC support while they use PCI Express. To support such firmwares, +forceload, a parameter of type bool, could enable AER to continue to +be initiated although firmwares have no _OSC support. To enable the +walkaround, pls. add aerdriver.forceload=y to kernel boot parameter line +when booting kernel. Note that forceload=n by default. + +2.3 AER error output +When a PCI-E AER error is captured, an error message will be outputed to +console. If it's a correctable error, it is outputed as a warning. +Otherwise, it is printed as an error.

Pls. refer to pci express specs for +other fields. + + +3. Developer Guide + +To enable AER aware support requires a software driver to configure +the AER capability structure within its device and to provide callbacks. + +To support AER better, developers need understand how AER does work +firstly. + +PCI Express errors are classified into two types: correctable errors +and uncorrectable errors. This classification is based on the impacts +of those errors, which may result in degraded performance or function +failure. + +Correctable errors pose no impacts on the functionality of the +interface. The PCI Express protocol can recover without any software +intervention or any loss of data. These errors are detected and +corrected by hardware. Unlike correctable errors, uncorrectable +errors impact functionality of the interface. Uncorrectable errors +can cause a particular transaction or a particular PCI Express link +to be unreliable. Depending on those error conditions, uncorrectable +errors are further classified into non-fatal errors and fatal errors. +Non-fatal errors cause the particular transaction to be unreliable, +but the PCI Express link itself is fully functional. Fatal errors, on +the other hand, cause the link to be unreliable. + +When AER is enabled, a PCI Express device will automatically send an +error message to the PCIE root port above it when the device captures +an error. The Root Port, upon receiving an error reporting message, +internally processes and logs the error message in its PCI Express +capability structure. Error information being logged includes storing +the error reporting agent's requestor ID into the Error Source +Identification Registers and setting the error bits of the Root Error +Status Register accordingly. If AER error reporting is enabled in Root +Error Command Register, the Root Port generates an interrupt if an +error is detected. + +Note that the errors as described above are related to the PCI Express +hierarchy and links. These errors do not include any device specific +errors because device specific errors will still get sent directly to +the device driver. + +3.1 Configure the AER capability structure + +AER aware drivers of PCI Express component need change the device +control registers to enable AER. They also could change AER registers, +including mask and severity registers. Helper function +pci_enable_pcie_error_reporting could be used to enable AER. See +section 3.3. + +3.2. Provide callbacks + +3.2.1 callback reset_link to reset pci express link + +This callback is used to reset the pci express physical link when a +fatal error happens. The root port aer service driver provides a +default reset_link function, but different upstream ports might +have different specifications to reset pci express link, so all +upstream ports should provide their own reset_link functions. + +In struct pcie_port_service_driver, a new pointer, reset_link, is +added. + +pci_ers_result_t (*reset_link) (struct pci_dev *dev); + +Section 3.2.2.2 provides more detailed info on when to call +reset_link. + +3.2.2 PCI error-recovery callbacks + +The PCI Express AER Root driver uses error callbacks to coordinate +with downstream device drivers associated with a hierarchy in question +when performing error recovery actions. + +Data struct pci_driver has a pointer, err_handler, to point to +pci_error_handlers who consists of a couple of callback function +pointers. AER driver follows the rules defined in +pci-error-recovery.txt except pci express specific parts (e.g. +reset_link). Pls. refer to pci-error-recovery.txt for detailed +definitions of the callbacks. + +Below sections specify when to call the error callback functions. + +3.2.2.1 Correctable errors + +Correctable errors pose no impacts on the functionality of +the interface. The PCI Express protocol can recover without any +software intervention or any loss of data. These errors do not +require any recovery actions. The AER driver clears the device's +correctable error status register accordingly and logs these errors. + +3.2.2.2 Non-correctable (non-fatal and fatal) errors + +If an error message indicates a non-fatal error, performing link reset +at upstream is not required. The AER driver calls error_detected(dev, +pci_channel_io_normal) to all drivers associated within a hierarchy in +question. for example, +EndPoint<==>DownstreamPort B<==>UpstreamPort A<==>RootPort. +If Upstream port A captures an AER error, the hierarchy consists of +Downstream port B and EndPoint. + +A driver may return PCI_ERS_RESULT_CAN_RECOVER, +PCI_ERS_RESULT_DISCONNECT, or PCI_ERS_RESULT_NEED_RESET, depending on +whether it can recover or the AER driver calls mmio_enabled as next. + +If an error message indicates a fatal error, kernel will broadcast +error_detected(dev, pci_channel_io_frozen) to all drivers within +a hierarchy in question. Then, performing link reset at upstream is +necessary. As different kinds of devices might use different approaches +to reset link, AER port service driver is required to provide the +function to reset link. Firstly, kernel looks for if the upstream +component has an aer driver. If it has, kernel uses the reset_link +callback of the aer driver. If the upstream component has no aer driver +and the port is downstream port, we will use the aer driver of the +root port who reports the AER error. As for upstream ports, +they should provide their own aer service drivers with reset_link +function. If error_detected returns PCI_ERS_RESULT_CAN_RECOVER and +reset_link returns PCI_ERS_RESULT_RECOVERED, the error handling goes +to mmio_enabled. + +3.3 helper functions + +3.3.1 int pci_find_aer_capability(struct pci_dev *dev); +pci_find_aer_capability locates the PCI Express AER capability +in the device configuration space.

But if the driver is not aware of +PCI Express, the device might not report its own errors to root +port. + +Q: What modifications will that driver need to make it compatible +with the PCI Express AER Root driver? + +A: It could call the helper functions to enable AER in devices and +cleanup uncorrectable status register.

Copyright 2004 Intel Corporation - -3. What is the PCI Express Port Bus Driver - -A PCI Express Port is a logical PCI-PCI Bridge structure. There -are two types of PCI Express Port: the Root Port and the Switch -Port. The Root Port originates a PCI Express link from a PCI Express -Root Complex and the Switch Port connects PCI Express links to -internal logical PCI buses. The Switch Port, which has its secondary -bus representing the switch's internal routing logic, is called the -switch's Upstream Port. The switch's Downstream Port is bridging from -switch's internal routing bus to a bus representing the downstream -PCI Express link from the PCI Express Switch. - -A PCI Express Port can provide up to four distinct functions, -referred to in this document as services, depending on its port type. -PCI Express Port's services include native hotplug support (HP), -power management event support (PME), advanced error reporting -support (AER), and virtual channel support (VC). These services may -be handled by a single complex driver or be individually distributed -and handled by corresponding service drivers. - -4. Why use the PCI Express Port Bus Driver? - -In existing Linux kernels, the Linux Device Driver Model allows a -physical device to be handled by only a single driver. The PCI -Express Port is a PCI-PCI Bridge device with multiple distinct -services. To maintain a clean and simple solution each service -may have its own software service driver. In this case several -service drivers will compete for a single PCI-PCI Bridge device. -For example, if the PCI Express Root Port native hotplug service -driver is loaded first, it claims a PCI-PCI Bridge Root Port. The -kernel therefore does not load other service drivers for that Root -Port. In other words, it is impossible to have multiple service -drivers load and run on a PCI-PCI Bridge device simultaneously -using the current driver model. - -To enable multiple service drivers running simultaneously requires -having a PCI Express Port Bus driver, which manages all populated -PCI Express Ports and distributes all provided service requests -to the corresponding service drivers as required. Some key -advantages of using the PCI Express Port Bus driver are listed below: - - - Allow multiple service drivers to run simultaneously on - a PCI-PCI Bridge Port device. - - - Allow service drivers implemented in an independent - staged approach. - - - Allow one service driver to run on multiple PCI-PCI Bridge - Port devices. - - - Manage and distribute resources of a PCI-PCI Bridge Port - device to requested service drivers. - -5. Configuring the PCI Express Port Bus Driver vs. Service Drivers - -5.1 Including the PCI Express Port Bus Driver Support into the Kernel - -Including the PCI Express Port Bus driver depends on whether the PCI -Express support is included in the kernel config. The kernel will -automatically include the PCI Express Port Bus driver as a kernel -driver when the PCI Express support is enabled in the kernel. - -5.2 Enabling Service Driver Support - -PCI device drivers are implemented based on Linux Device Driver Model. -All service drivers are PCI device drivers. As discussed above, it is -impossible to load any service driver once the kernel has loaded the -PCI Express Port Bus Driver. To meet the PCI Express Port Bus Driver -Model requires some minimal changes on existing service drivers that -imposes no impact on the functionality of existing service drivers. - -A service driver is required to use the two APIs shown below to -register its service with the PCI Express Port Bus driver (see -section 5.2.1 & 5.2.2). It is important that a service driver -initializes the pcie_port_service_driver data structure, included in -header file /include/linux/pcieport_if.h, before calling these APIs. -Failure to do so will result an identity mismatch, which prevents -the PCI Express Port Bus driver from loading a service driver. - -5.2.1 pcie_port_service_register - -int pcie_port_service_register(struct pcie_port_service_driver *new) - -This API replaces the Linux Driver Model's pci_module_init API. A -service driver should always calls pcie_port_service_register at -module init. Note that after service driver being loaded, calls -such as pci_enable_device(dev) and pci_set_master(dev) are no longer -necessary since these calls are executed by the PCI Port Bus driver. - -5.2.2 pcie_port_service_unregister - -void pcie_port_service_unregister(struct pcie_port_service_driver *new) - -pcie_port_service_unregister replaces the Linux Driver Model's -pci_unregister_driver.

Possible Resource Conflicts - -Since all service drivers of a PCI-PCI Bridge Port device are -allowed to run simultaneously, below lists a few of possible resource -conflicts with proposed solutions. - -6.1 MSI Vector Resource - -The MSI capability structure enables a device software driver to call -pci_enable_msi to request MSI based interrupts. Once MSI interrupts -are enabled on a device, it stays in this mode until a device driver -calls pci_disable_msi to disable MSI interrupts and revert back to -INTx emulation mode. Since service drivers of the same PCI-PCI Bridge -port share the same physical device, if an individual service driver -calls pci_enable_msi/pci_disable_msi it may result unpredictable -behavior. For example, two service drivers run simultaneously on the -same physical Root Port. Both service drivers call pci_enable_msi to -request MSI based interrupts. A service driver may not know whether -any other service drivers have run on this Root Port. If either one -of them calls pci_disable_msi, it puts the other service driver -in a wrong interrupt mode. - -To avoid this situation all service drivers are not permitted to -switch interrupt mode on its device. The PCI Express Port Bus driver -is responsible for determining the interrupt mode and this should be -transparent to service drivers. Service drivers need to know only -the vector IRQ assigned to the field irq of struct pcie_device, which -is passed in when the PCI Express Port Bus driver probes each service -driver. Service drivers should use (struct pcie_device*)dev->irq to -call request_irq/free_irq. In addition, the interrupt mode is stored -in the field interrupt_mode of struct pcie_device. - -6.2 MSI-X Vector Resources - -Similar to the MSI a device driver for an MSI-X capable device can -call pci_enable_msix to request MSI-X interrupts. All service drivers -are not permitted to switch interrupt mode on its device.

Some of the more advanced -chipsets are able to deal with these errors; these include PCI-E chipsets, -and the PCI-host bridges found on IBM Power4 and Power5-based pSeries -boxes. A typical action taken is to disconnect the affected device, -halting all I/O to it.

Typically, a reconnection mechanism is also -offered, so that the affected PCI device(s) are reset and put back -into working condition. The reset phase requires coordination -between the affected device drivers and the PCI controller chip. -This document describes a generic API for notifying device drivers -of a bus disconnection, and then performing error recovery. -This API is currently implemented in the 2.6.16 and later kernels. - -Reporting and recovery is performed in several steps. First, when -a PCI hardware error has resulted in a bus disconnect, that event -is reported as soon as possible to all affected device drivers, -including multiple instances of a device driver on multi-function -cards. This allows device drivers to avoid deadlocking in spinloops, -waiting for some i/o-space register to change, when it never will. -It also gives the drivers a chance to defer incoming I/O as -needed. - -Next, recovery is performed in several stages. Most of the complexity -is forced by the need to handle multi-function devices, that is, -devices that have multiple device drivers associated with them. -In the first stage, each driver is allowed to indicate what type -of reset it desires, the choices being a simple re-enabling of I/O -or requesting a hard reset (a full electrical #RST of the PCI card). -If any driver requests a full reset, that is what will be done. - -After a full reset and/or a re-enabling of I/O, all drivers are -again notified, so that they may then perform any device setup/config -that may be required. After these have all completed, a final -"resume normal operations" event is sent out. - -The biggest reason for choosing a kernel-based implementation rather -than a user-space implementation was the need to deal with bus -disconnects of PCI devices attached to storage media, and, in particular, -disconnects from devices holding the root file system. If the root -file system is disconnected, a user-space mechanism would have to go -through a large number of contortions to complete recovery. Almost all -of the current Linux file systems are not tolerant of disconnection -from/reconnection to their underlying block device. By contrast, -bus errors are easy to manage in the device driver.

On powerpc, the slot -is isolated, in that all I/O is blocked: all reads return 0xffffffff, -all writes are ignored. - - -STEP 1: Notification --------------------- -Platform calls the error_detected() callback on every instance of -every driver affected by the error. - -At this point, the device might not be accessible anymore, depending on -the platform (the slot will be isolated on powerpc). The driver may -already have "noticed" the error because of a failing I/O, but this -is the proper "synchronization point", that is, it gives the driver -a chance to cleanup, waiting for pending stuff (timers, whatever, etc...) -to complete; it can take semaphores, schedule, etc... everything but -touch the device.

(To be defined more precisely) - -The next step taken depends on the results returned by the drivers. -If all drivers returned PCI_ERS_RESULT_RECOVERED, then the platform -proceeds to either STEP3 (Link Reset) or to STEP 5 (Resume Operations). - -If any driver returned PCI_ERS_RESULT_NEED_RESET, then the platform -proceeds to STEP 4 (Slot Reset) - ->>> The current powerpc implementation does not implement this callback. - - -STEP 3: Link Reset ------------------- -The platform resets the link, and then calls the link_reset() callback -on all affected device drivers. This is a PCI-Express specific state -and is done whenever a non-fatal error has been detected that can be -"solved" by resetting the link. This call informs the driver of the -reset and the driver should check to see if the device appears to be -in working condition. - -The driver is not supposed to restart normal driver I/O operations -at this point. It should limit itself to "probing" the device to -check it's recoverability status. If all is right, then the platform -will call resume() once all drivers have ack'd link_reset(). - - Result codes: - (identical to STEP 3 (MMIO Enabled) - -The platform then proceeds to either STEP 4 (Slot Reset) or STEP 5 -(Resume Operations). - ->>> The current powerpc implementation does not implement this callback. - - -STEP 4: Slot Reset ------------------- -The platform performs a soft or hard reset of the device, and then -calls the slot_reset() callback. - -A soft reset consists of asserting the adapter #RST line and then -restoring the PCI BAR's and PCI configuration header to a state -that is equivalent to what it would be after a fresh system -power-on followed by power-on BIOS/system firmware initialization. -If the platform supports PCI hotplug, then the reset might be -performed by toggling the slot electrical power off/on. - -It is important for the platform to restore the PCI config space -to the "fresh poweron" state, rather than the "last state". After -a slot reset, the device driver will almost always use its standard -device initialization routines, and an unusual config space setup -may result in hung devices, kernel panics, or silent data corruption. - -This call gives drivers the chance to re-initialize the hardware -(re-download firmware, etc.). At this point, the driver may assume -that he card is in a fresh state and is fully functional. In -particular, interrupt generation should work normally. - -Drivers should not yet restart normal I/O processing operations -at this point. If all device drivers report success on this -callback, the platform will call resume() to complete the sequence, -and let the driver restart normal I/O processing. - -A driver can still return a critical failure for this function if -it can't get the device operational after reset. If the platform -previously tried a soft reset, it might now try a hard reset (power -cycle) and then call slot_reset() again. It the device still can't -be recovered, there is nothing more that can be done; the platform -will typically report a "permanent failure" in such a case. The -device will be considered "dead" in this case. - -Drivers for multi-function cards will need to coordinate among -themselves as to which driver instance will perform any "one-shot" -or global device initialization. For example, the Symbios sym53cxx2 -driver performs device init only from PCI function 0: - -+ if (PCI_FUNC(pdev->devfn) == 0) -+ sym_reset_scsi_bus(np, 0); - - Result codes: - - PCI_ERS_RESULT_DISCONNECT - Same as above. - -Platform proceeds either to STEP 5 (Resume Operations) or STEP 6 (Permanent -Failure). - ->>> The current powerpc implementation does not currently try a ->>> power-cycle reset if the driver returned PCI_ERS_RESULT_DISCONNECT. ->>> However, it probably should. - - -STEP 5: Resume Operations -------------------------- -The platform will call the resume() callback on all affected device -drivers if all drivers on the segment have returned -PCI_ERS_RESULT_RECOVERED from one of the 3 previous callbacks. -The goal of this callback is to tell the driver to restart activity, -that everything is back and running. This callback does not return -a result code. - -At this point, if a new error happens, the platform will restart -a new error recovery sequence. - -STEP 6: Permanent Failure -------------------------- -A "permanent failure" has occurred, and the platform cannot recover -the device. The platform will call error_detected() with a -pci_channel_state value of pci_channel_io_perm_failure. - -The device driver should, at this point, assume the worst. It should -cancel all pending I/O, refuse all new I/O, returning -EIO to -higher layers. The device driver should then clean up all of its -memory and remove itself from kernel operations, much as it would -during system shutdown. - -The platform will typically notify the system operator of the -permanent failure in some way. If the device is hotplug-capable, -the operator will probably want to remove and replace the device. -Note, however, not all failures are truly "permanent". Some are -caused by over-heating, some by a poorly seated card. Many -PCI error events are caused by software bugs, e.g. DMA's to -wild addresses or bogus split transactions due to programming -errors. See the discussion in powerpc/eeh-pci-error-recovery.txt -for additional detail on real-life experience of the causes of -software errors. - - -Conclusion; General Remarks ---------------------------- -The way those callbacks are called is platform policy. A platform with -no slot reset capability may want to just "ignore" drivers that can't -recover (disconnect them) and try to let other cards on the same segment -recover. Keep in mind that in most real life cases, though, there will -be only one driver per segment. - -Now, a note about interrupts. If you get an interrupt and your -device is dead or has been isolated, there is a problem :) -The current policy is to turn this into a platform policy. -That is, the recovery API only requires that: - - - There is no guarantee that interrupt delivery can proceed from any -device on the segment starting from the error detection and until the -resume callback is sent, at which point interrupts are expected to be -fully operational. - - - There is no guarantee that interrupt delivery is stopped, that is, -a driver that gets an interrupt after detecting an error, or that detects -an error within the interrupt handler such that it prevents proper -ack'ing of the interrupt (and thus removal of the source) should just -return IRQ_NOTHANDLED. It's up to the platform to deal with that -condition, typically by masking the IRQ source during the duration of -the error handling. It is expected that the platform "knows" which -interrupts are routed to error-management capable slots and can deal -with temporarily disabling that IRQ number during error processing (this -isn't terribly complex). That means some IRQ latency for other devices -sharing the interrupt, but there is simply no other way.

Most drivers should export this - table using MODULE_DEVICE_TABLE(pci,...). - - probe This probing function gets called (during execution - of pci_register_driver() for already existing - devices or later if a new device gets inserted) for - all PCI devices which match the ID table and are not - "owned" by the other drivers yet. This function gets - passed a "struct pci_dev *" for each device whose - entry in the ID table matches the device.

Each entry consists of: - - vendor,device Vendor and device ID to match (or PCI_ANY_ID) - - subvendor, Subsystem vendor and device ID to match (or PCI_ANY_ID) - subdevice, - - class Device class, subclass, and "interface" to match. - See Appendix D of the PCI Local Bus Spec or - include/linux/pci_ids.h for a full list of classes. - Most drivers do not need to specify class/class_mask - as vendor/device is normally sufficient. - - class_mask limit which sub-fields of the class field are compared. - See drivers/scsi/sym53c8xx_2/ for example of usage. - - driver_data Data private to the driver. - Most drivers don't need to use driver_data field. - Best practice is to use driver_data as an index - into a static list of equivalent device types, - instead of using it as a pointer. - - -Most drivers only need PCI_DEVICE() or PCI_DEVICE_CLASS() to set up -a pci_device_id table. - -New PCI IDs may be added to a device driver pci_ids table at runtime -as shown below: - -echo "vendor device subvendor subdevice class class_mask driver_data" > \ -/sys/bus/pci/drivers/{driver}/new_id - -All fields are passed in as hexadecimal values (no leading 0x). -The vendor and device fields are mandatory, the others are optional.

This allows searching for any device from a -specific vendor, for example. - -These functions are hotplug-safe. They increment the reference count on -the pci_dev that they return. You must eventually (possibly at module unload) -decrement the reference count on these devices by calling pci_dev_put(). - - - -3. Device Initialization Steps -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -As noted in the introduction, most PCI drivers need the following steps -for device initialization: - - Enable the device - Request MMIO/IOP resources - Set the DMA mask size (for both coherent and streaming DMA) - Allocate and initialize shared control data (pci_allocate_coherent()) - Access device configuration space (if needed) - Register IRQ handler (request_irq()) - Initialize non-PCI (i.e. LAN/SCSI/etc parts of the chip) - Enable DMA/processing engines. - -The driver can access PCI config space registers at any time. -(Well, almost. When running BIST, config space can go away...but -that will just result in a PCI Bus Master Abort and config reads -will return garbage). - - -3.1 Enable the PCI device -~~~~~~~~~~~~~~~~~~~~~~~~~ -Before touching any device registers, the driver needs to enable -the PCI device by calling pci_enable_device(). This will: - o wake up the device if it was in suspended state, - o allocate I/O and memory regions of the device (if BIOS did not), - o allocate an IRQ (if BIOS did not). - -NOTE: pci_enable_device() can fail! Check the return value. - -[ OS BUG: we don't check resource allocations before enabling those - resources. The sequence would make more sense if we called - pci_request_resources() before calling pci_enable_device(). - Currently, the device drivers can't detect the bug when when two - devices have been allocated the same range. This is not a common - problem and unlikely to get fixed soon. - - This has been discussed before but not changed as of 2.6.19: - http://lkml.org/lkml/2006/3/2/194 -] - -pci_set_master() will enable DMA by setting the bus master bit -in the PCI_COMMAND register. It also fixes the latency timer value if -it's set to something bogus by the BIOS. - -If the PCI device can use the PCI Memory-Write-Invalidate transaction, -call pci_set_mwi(). This enables the PCI_COMMAND bit for Mem-Wr-Inval -and also ensures that the cache line size register is set correctly. -Check the return value of pci_set_mwi() as not all architectures -or chip-sets may support Memory-Write-Invalidate. Alternatively, -if Mem-Wr-Inval would be nice to have but is not required, call -pci_try_set_mwi() to have the system do its best effort at enabling -Mem-Wr-Inval. - - -3.2 Request MMIO/IOP resources -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -Memory (MMIO), and I/O port addresses should NOT be read directly -from the PCI device config space. Use the values in the pci_dev structure -as the PCI "bus address" might have been remapped to a "host physical" -address by the arch/chip-set specific kernel support. - -See Documentation/IO-mapping.txt for how to access device registers -or device memory. - -The device driver needs to call pci_request_region() to verify -no other device is already using the same address resource. -Conversely, drivers should call pci_release_region() AFTER -calling pci_disable_device(). -The idea is to prevent two devices colliding on the same address range. - -[ See OS BUG comment above. Currently (2.6.19), The driver can only - determine MMIO and IO Port resource availability _after_ calling - pci_enable_device(). ] - -Generic flavors of pci_request_region() are request_mem_region() -(for MMIO ranges) and request_region() (for IO Port ranges). -Use these for address resources that are not described by "normal" PCI -BARs. - -Also see pci_request_selected_regions() below. - - -3.3 Set the DMA mask size -~~~~~~~~~~~~~~~~~~~~~~~~~ -[ If anything below doesn't make sense, please refer to - Documentation/DMA-API.txt. This section is just a reminder that - drivers need to indicate DMA capabilities of the device and is not - an authoritative source for DMA interfaces. ] - -While all drivers should explicitly indicate the DMA capability -(e.g. 32 or 64 bit) of the PCI bus master, devices with more than -32-bit bus master capability for streaming data need the driver -to "register" this capability by calling pci_set_dma_mask() with -appropriate parameters. In general this allows more efficient DMA -on systems where System RAM exists above 4G _physical_ address. - -Drivers for all PCI-X and PCIe compliant devices must call -pci_set_dma_mask() as they are 64-bit DMA devices. - -Similarly, drivers must also "register" this capability if the device -can directly address "consistent memory" in System RAM above 4G physical -address by calling pci_set_consistent_dma_mask(). -Again, this includes drivers for all PCI-X and PCIe compliant devices. -Many 64-bit "PCI" devices (before PCI-X) and some PCI-X devices are -64-bit DMA capable for payload ("streaming") data but not control -("consistent") data. - - -3.4 Setup shared control data -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -Once the DMA masks are set, the driver can allocate "consistent" (a.k.a. shared) -memory. See Documentation/DMA-API.txt for a full description of -the DMA APIs. This section is just a reminder that it needs to be done -before enabling DMA on the device. - - -3.5 Initialize device registers -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -Some drivers will need specific "capability" fields programmed -or other "vendor specific" register initialized or reset. -E.g. clearing pending interrupts. - - -3.6 Register IRQ handler -~~~~~~~~~~~~~~~~~~~~~~~~ -While calling request_irq() is the last step described here, -this is often just another intermediate step to initialize a device. -This step can often be deferred until the device is opened for use. - -All interrupt handlers for IRQ lines should be registered with IRQF_SHARED -and use the devid to map IRQs to devices (remember that all PCI IRQ lines -can be shared). - -request_irq() will associate an interrupt handler and device handle -with an interrupt number. Historically interrupt numbers represent -IRQ lines which run from the PCI device to the Interrupt controller. -With MSI and MSI-X (more below) the interrupt number is a CPU "vector". - -request_irq() also enables the interrupt. Make sure the device is -quiesced and does not have any interrupts pending before registering -the interrupt handler. - -MSI and MSI-X are PCI capabilities. Both are "Message Signaled Interrupts" -which deliver interrupts to the CPU via a DMA write to a Local APIC. -The fundamental difference between MSI and MSI-X is how multiple -"vectors" get allocated. MSI requires contiguous blocks of vectors -while MSI-X can allocate several individual ones. - -MSI capability can be enabled by calling pci_enable_msi() or -pci_enable_msix() before calling request_irq(). This causes -the PCI support to program CPU vector data into the PCI device -capability registers. - -If your PCI device supports both, try to enable MSI-X first. -Only one can be enabled at a time. Many architectures, chip-sets, -or BIOSes do NOT support MSI or MSI-X and the call to pci_enable_msi/msix -will fail. This is important to note since many drivers have -two (or more) interrupt handlers: one for MSI/MSI-X and another for IRQs. -They choose which handler to register with request_irq() based on the -return value from pci_enable_msi/msix(). - -There are (at least) two really good reasons for using MSI: -1) MSI is an exclusive interrupt vector by definition. - This means the interrupt handler doesn't have to verify - its device caused the interrupt. - -2) MSI avoids DMA/IRQ race conditions. DMA to host memory is guaranteed - to be visible to the host CPU(s) when the MSI is delivered. This - is important for both data coherency and avoiding stale control data. - This guarantee allows the driver to omit MMIO reads to flush - the DMA stream. - -See drivers/infiniband/hw/mthca/ or drivers/net/tg3.c for examples -of MSI/MSI-X usage. - - - -4. PCI device shutdown -~~~~~~~~~~~~~~~~~~~~~~~ - -When a PCI device driver is being unloaded, most of the following -steps need to be performed: - - Disable the device from generating IRQs - Release the IRQ (free_irq()) - Stop all DMA activity - Release DMA buffers (both streaming and consistent) - Unregister from other subsystems (e.g. scsi or netdev) - Disable device from responding to MMIO/IO Port addresses - Release MMIO/IO Port resource(s) - - -4.1 Stop IRQs on the device -~~~~~~~~~~~~~~~~~~~~~~~~~~~ -How to do this is chip/device specific. If it's not done, it opens -the possibility of a "screaming interrupt" if (and only if) -the IRQ is shared with another device. - -When the shared IRQ handler is "unhooked", the remaining devices -using the same IRQ line will still need the IRQ enabled. Thus if the -"unhooked" device asserts IRQ line, the system will respond assuming -it was one of the remaining devices asserted the IRQ line. Since none -of the other devices will handle the IRQ, the system will "hang" until -it decides the IRQ isn't going to get handled and masks the IRQ (100,000 -iterations later). Once the shared IRQ is masked, the remaining devices -will stop functioning properly. Not a nice situation. - -This is another reason to use MSI or MSI-X if it's available. -MSI and MSI-X are defined to be exclusive interrupts and thus -are not susceptible to the "screaming interrupt" problem. - - -4.2 Release the IRQ -~~~~~~~~~~~~~~~~~~~ -Once the device is quiesced (no more IRQs), one can call free_irq(). -This function will return control once any pending IRQs are handled, -"unhook" the drivers IRQ handler from that IRQ, and finally release -the IRQ if no one else is using it. - - -4.3 Stop all DMA activity -~~~~~~~~~~~~~~~~~~~~~~~~~ -It's extremely important to stop all DMA operations BEFORE attempting -to deallocate DMA control data. Failure to do so can result in memory -corruption, hangs, and on some chip-sets a hard crash. - -Stopping DMA after stopping the IRQs can avoid races where the -IRQ handler might restart DMA engines. - -While this step sounds obvious and trivial, several "mature" drivers -didn't get this step right in the past. - - -4.4 Release DMA buffers -~~~~~~~~~~~~~~~~~~~~~~~ -Once DMA is stopped, clean up streaming DMA first. -I.e. unmap data buffers and return buffers to "upstream" -owners if there is one. - -Then clean up "consistent" buffers which contain the control data. - -See Documentation/DMA-API.txt for details on unmapping interfaces. - - -4.5 Unregister from other subsystems -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -Most low level PCI device drivers support some other subsystem -like USB, ALSA, SCSI, NetDev, Infiniband, etc. Make sure your -driver isn't losing resources from that other subsystem. -If this happens, typically the symptom is an Oops (panic) when -the subsystem attempts to call into a driver that has been unloaded. - - -4.6 Disable Device from responding to MMIO/IO Port addresses -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -io_unmap() MMIO or IO Port resources and then call pci_disable_device(). -This is the symmetric opposite of pci_enable_device(). -Do not access device registers after calling pci_disable_device(). - - -4.7 Release MMIO/IO Port Resource(s) -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -Call pci_release_region() to mark the MMIO or IO Port range as available. -Failure to do so usually results in the inability to reload the driver. - - - -5. How to access PCI config space -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -You can use pci_(read|write)_config_(byte|word|dword) to access the config -space of a device represented by struct pci_dev *. All these functions return 0 -when successful or an error code (PCIBIOS_...) which can be translated to a text -string by pcibios_strerror. Most drivers expect that accesses to valid PCI -devices don't fail. - -If you don't have a struct pci_dev available, you can call -pci_bus_(read|write)_config_(byte|word|dword) to access a given device -and function on that bus. - -If you access fields in the standard portion of the config header, please -use symbolic names of locations and bits declared in . - -If you need to access Extended PCI Capability registers, just call -pci_find_capability() for the particular capability and it will find the -corresponding register block for you. - - - -6. Other interesting functions -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -pci_find_slot() Find pci_dev corresponding to given bus and - slot numbers. -pci_set_power_state() Set PCI Power Management state (0=D0 ... 3=D3) -pci_find_capability() Find specified capability in device's capability - list. -pci_resource_start() Returns bus start address for a given PCI region -pci_resource_end() Returns bus end address for a given PCI region -pci_resource_len() Returns the byte length of a PCI region -pci_set_drvdata() Set private driver data pointer for a pci_dev -pci_get_drvdata() Return private driver data pointer for a pci_dev -pci_set_mwi() Enable Memory-Write-Invalidate transactions. -pci_clear_mwi() Disable Memory-Write-Invalidate transactions. - - - -7. Miscellaneous hints -~~~~~~~~~~~~~~~~~~~~~~ - -When displaying PCI device names to the user (for example when a driver wants -to tell the user what card has it found), please use pci_name(pci_dev). - -Always refer to the PCI devices by a pointer to the pci_dev structure. -All PCI layer functions use this identification and it's the only -reasonable one. Don't use bus/slot/function numbers except for very -special purposes -- on systems with multiple primary buses their semantics -can be pretty complex. - -Don't try to turn on Fast Back to Back writes in your driver. All devices -on the bus need to be capable of doing it, so this is something which needs -to be handled by platform and generic code, not individual drivers. - - - -8. Vendor and device identifications -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -One is not not required to add new device ids to include/linux/pci_ids.h. -Please add PCI_VENDOR_ID_xxx for vendors and a hex constant for device ids. - -PCI_VENDOR_ID_xxx constants are re-used. The device ids are arbitrary -hex numbers (vendor controlled) and normally used only in a single -location, the pci_device_id table. - -Please DO submit new vendor/device ids to pciids.sourceforge.net project. - - - -9. Obsolete functions -~~~~~~~~~~~~~~~~~~~~~ - -There are several functions which you might come across when trying to -port an old driver to the new PCI interface. They are no longer present -in the kernel as they aren't compatible with hotplug or PCI domains or -having sane locking. - -pci_find_device() Superseded by pci_get_device() -pci_find_subsys() Superseded by pci_get_subsys() -pci_find_slot() Superseded by pci_get_slot() - - -The alternative is the traditional PCI device driver that walks PCI -device lists. This is still possible but discouraged. - - - -10. MMIO Space and "Write Posting" -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Converting a driver from using I/O Port space to using MMIO space -often requires some additional changes. Specifically, "write posting" -needs to be handled. Many drivers (e.g. tg3, acenic, sym53c8xx_2) -already do this. I/O Port space guarantees write transactions reach the PCI -device before the CPU can continue. Writes to MMIO space allow the CPU -to continue before the transaction reaches the PCI device. HW weenies -call this "Write Posting" because the write completion is "posted" to -the CPU before the transaction has reached its destination. - -Thus, timing sensitive code should add readl() where the CPU is -expected to wait before doing other work. The classic "bit banging" -sequence works fine for I/O Port space: - - for (i = 8; --i; val >>= 1) { - outb(val & 1, ioport_reg); /* write bit */ - udelay(10); - } - -The same sequence for MMIO space should be: - - for (i = 8; --i; val >>= 1) { - writeb(val & 1, mmio_reg); /* write bit */ - readb(safe_mmio_reg); /* flush posted write */ - udelay(10); - } - -It is important that "safe_mmio_reg" not have any side effects that -interferes with the correct operation of the device. - -Another case to watch out for is when resetting a PCI device. Use PCI -Configuration space reads to flush the writel(). This will gracefully -handle the PCI master abort on all platforms if the PCI device is -expected to not respond to a readl(). Most x86 platforms will allow -MMIO reads to master abort (a.k.a. "Soft Fail") and return garbage -(e.g. ~0). But many RISC platforms will crash (a.k.a."Hard Fail"). - diff --git a/Documentation/pcieaer-howto.txt b/Documentation/pcieaer-howto.txt deleted file mode 100644 index d5da86170106..000000000000 --- a/Documentation/pcieaer-howto.txt +++ /dev/null @@ -1,253 +0,0 @@ - The PCI Express Advanced Error Reporting Driver Guide HOWTO - T.

The baseline capability is -required of all PCI Express components providing a minimum defined -set of error reporting requirements. Advanced Error Reporting -capability is implemented with a PCI Express advanced error reporting -extended capability structure providing more robust error reporting. - -The PCI Express AER driver provides the infrastructure to support PCI -Express Advanced Error Reporting capability. The PCI Express AER -driver provides three basic functions: - -- Gathers the comprehensive error information if errors occurred. -- Reports error to the users. -- Performs error recovery actions. - -AER driver only attaches root ports which support PCI-Express AER -capability. - - -2. User Guide - -2.1 Include the PCI Express AER Root Driver into the Linux Kernel - -The PCI Express AER Root driver is a Root Port service driver attached -to the PCI Express Port Bus driver.

Enabling the AER -Root driver and having AER support in BIOS may result unpredictable -behavior. To avoid this conflict, a successful load of the AER Root driver -requires ACPI _OSC support in the BIOS to allow the AER Root driver to -request for native control of AER.

Developer Guide - -To enable AER aware support requires a software driver to configure -the AER capability structure within its device and to provide callbacks. - -To support AER better, developers need understand how AER does work -firstly. - -PCI Express errors are classified into two types: correctable errors -and uncorrectable errors. This classification is based on the impacts -of those errors, which may result in degraded performance or function -failure. - -Correctable errors pose no impacts on the functionality of the -interface. The PCI Express protocol can recover without any software -intervention or any loss of data. These errors are detected and -corrected by hardware. Unlike correctable errors, uncorrectable -errors impact functionality of the interface. Uncorrectable errors -can cause a particular transaction or a particular PCI Express link -to be unreliable. Depending on those error conditions, uncorrectable -errors are further classified into non-fatal errors and fatal errors. -Non-fatal errors cause the particular transaction to be unreliable, -but the PCI Express link itself is fully functional. Fatal errors, on -the other hand, cause the link to be unreliable. - -When AER is enabled, a PCI Express device will automatically send an -error message to the PCIE root port above it when the device captures -an error. The Root Port, upon receiving an error reporting message, -internally processes and logs the error message in its PCI Express -capability structure. Error information being logged includes storing -the error reporting agent's requestor ID into the Error Source -Identification Registers and setting the error bits of the Root Error -Status Register accordingly. If AER error reporting is enabled in Root -Error Command Register, the Root Port generates an interrupt if an -error is detected. - -Note that the errors as described above are related to the PCI Express -hierarchy and links. These errors do not include any device specific -errors because device specific errors will still get sent directly to -the device driver. - -3.1 Configure the AER capability structure - -AER aware drivers of PCI Express component need change the device -control registers to enable AER. They also could change AER registers, -including mask and severity registers. Helper function -pci_enable_pcie_error_reporting could be used to enable AER. See -section 3.3. - -3.2. Provide callbacks - -3.2.1 callback reset_link to reset pci express link - -This callback is used to reset the pci express physical link when a -fatal error happens. The root port aer service driver provides a -default reset_link function, but different upstream ports might -have different specifications to reset pci express link, so all -upstream ports should provide their own reset_link functions. - -In struct pcie_port_service_driver, a new pointer, reset_link, is -added. - -pci_ers_result_t (*reset_link) (struct pci_dev *dev); - -Section 3.2.2.2 provides more detailed info on when to call -reset_link. - -3.2.2 PCI error-recovery callbacks - -The PCI Express AER Root driver uses error callbacks to coordinate -with downstream device drivers associated with a hierarchy in question -when performing error recovery actions. - -Data struct pci_driver has a pointer, err_handler, to point to -pci_error_handlers who consists of a couple of callback function -pointers. AER driver follows the rules defined in -pci-error-recovery.txt except pci express specific parts (e.g. -reset_link). Pls. refer to pci-error-recovery.txt for detailed -definitions of the callbacks. - -Below sections specify when to call the error callback functions. - -3.2.2.1 Correctable errors - -Correctable errors pose no impacts on the functionality of -the interface. The PCI Express protocol can recover without any -software intervention or any loss of data. These errors do not -require any recovery actions. The AER driver clears the device's -correctable error status register accordingly and logs these errors. - -3.2.2.2 Non-correctable (non-fatal and fatal) errors - -If an error message indicates a non-fatal error, performing link reset -at upstream is not required. The AER driver calls error_detected(dev, -pci_channel_io_normal) to all drivers associated within a hierarchy in -question. for example, -EndPoint<==>DownstreamPort B<==>UpstreamPort A<==>RootPort. -If Upstream port A captures an AER error, the hierarchy consists of -Downstream port B and EndPoint. - -A driver may return PCI_ERS_RESULT_CAN_RECOVER, -PCI_ERS_RESULT_DISCONNECT, or PCI_ERS_RESULT_NEED_RESET, depending on -whether it can recover or the AER driver calls mmio_enabled as next. - -If an error message indicates a fatal error, kernel will broadcast -error_detected(dev, pci_channel_io_frozen) to all drivers within -a hierarchy in question. Then, performing link reset at upstream is -necessary. As different kinds of devices might use different approaches -to reset link, AER port service driver is required to provide the -function to reset link. Firstly, kernel looks for if the upstream -component has an aer driver. If it has, kernel uses the reset_link -callback of the aer driver. If the upstream component has no aer driver -and the port is downstream port, we will use the aer driver of the -root port who reports the AER error. As for upstream ports, -they should provide their own aer service drivers with reset_link -function. If error_detected returns PCI_ERS_RESULT_CAN_RECOVER and -reset_link returns PCI_ERS_RESULT_RECOVERED, the error handling goes -to mmio_enabled. - -3.3 helper functions - -3.3.1 int pci_find_aer_capability(struct pci_dev *dev); -pci_find_aer_capability locates the PCI Express AER capability -in the device configuration space.

If the -error is fatal, kernel will print out warning messages. Please refer -to section 3 for more information. - -Q: What happens if an upstream port service driver does not provide -callback reset_link? - -A: Fatal error recovery will fail if the errors are reported by the -upstream ports who are attached by the service driver. - -Q: How does this infrastructure deal with driver that is not PCI -Express aware? - -A: This infrastructure calls the error callback functions of the -driver when an error happens. But if the driver is not aware of -PCI Express, the device might not report its own errors to root -port. - -Q: What modifications will that driver need to make it compatible -with the PCI Express AER Root driver? - -A: It could call the helper functions to enable AER in devices and -cleanup uncorrectable status register.

This second list is sorted at boot time, in "BIOS" order, to try to remain compatible with older kernels (2.2 and earlier days). There was also a "nosort" option to turn this sorting off, to remain compatible with even older kernel versions, but that just ends up being what we have been doing from 2.5 days... Unfortunately, the second list of devices is not really ever used to determine the probing order of PCI devices or drivers[1]. That is done using the driver core list instead. This change happened back in the early 2.5 days. Relying on BIOS ording for the binding of drivers to specific device names is problematic for many reasons, and userspace tools like udev exist to properly name devices in a persistant manner if that is needed, no reliance on the BIOS is needed. Matt Domsch and others at Dell noticed this back in 2006, and added a boot option to sort the PCI device lists (both of them) in a breadth-first manner to help remain compatible with the 2.4 order, if needed for any reason. This option is not going away, as some systems rely on them. This patch removes the sorting of the internal PCI device list in "BIOS" mode, as it's not needed at all anymore, and hasn't for many years. I've also removed the PCI flags for this from some other arches that for some reason defined them, but never used them. This should not change the ordering of any drivers or device probing. [1] The old-style pci_get_device and pci_find_device() still used this sorting order, but there are very few drivers that use these functions, as they are deprecated for use in this manner. If for some reason, a driver rely on the order and uses these functions, the breadth-first boot option will resolve any problem.

It works by building a list of to be flushed IOTLB entries and a bitmap list of which DMAR engine they are from. After either a high water mark (250 accessible via debugfs) or 10ms the list of iova's will be reclaimed and the DMAR engines associated are IOTLB-flushed. This approach recovers 15 to 20% of the performance lost when using the IOMMU for my netperf udp stream benchmark with small packets. It can be disabled with a kernel boot parameter "intel_iommu=strict". Its use does weaken the IOMMU protections a bit.

It is generally unsafe to read this information through the existing interfaces to user-land because of stateful interfaces. This adds: - abstract operations for VPD access (struct pci_vpd_ops) - VPD state information in struct pci_dev (struct pci_vpd) - an implementation of the VPD access method specified in PCI 2.2 (in access.c) - a 'vpd' binary file in sysfs directories for PCI devices with VPD operations defined It adds a probe for PCI 2.2 VPD in pci_scan_device() and release of VPD state in pci_release_dev().

Code shared between /proc//mounts and /proc//mountinfo is extracted into separate functions. Thanks to Al Viro for the help in getting the design right.

To see which version of mount.nfs + you are using, type: + + > /sbin/mount.nfs -V + + If the version is less than 1.1.1 or the command does not exist, + then you will need to install the latest version of nfs-utils. + + Download the latest package from: + + http://www.kernel.org/pub/linux/utils/nfs + + Uncompress the package and follow the installation instructions. + + If you will not be using GSS and NFSv4, the installation process + can be simplified by disabling these features when running configure: + + > ./configure --disable-gss --disable-nfsv4 + + For more information on this see the package's README and INSTALL files. + + After building the nfs-utils package, there will be a mount.nfs binary in + the utils/mount directory. This binary can be used to initiate NFS v2, v3, + or v4 mounts. To initiate a v4 mount, the binary must be called mount.nfs4. + The standard technique is to create a symlink called mount.nfs4 to mount.nfs. + + NOTE: mount.nfs and therefore nfs-utils-1.1.1 or greater is only needed + on the NFS client machine. You do not need this specific version of + nfs-utils on the server. Furthermore, only the mount.nfs command from + nfs-utils-1.1.1 is needed on the client. + + - Install a Linux kernel with NFS/RDMA + + The NFS/RDMA client and server are both included in the mainline Linux + kernel version 2.6.25 and later. This and other versions of the 2.6 Linux + kernel can be found at: + + ftp://ftp.kernel.org/pub/linux/kernel/v2.6/ + + Download the sources and place them in an appropriate location. + + - Configure the RDMA stack + + Make sure your kernel configuration has RDMA support enabled. Under + Device Drivers -> InfiniBand support, update the kernel configuration + to enable InfiniBand support [NOTE: the option name is misleading. Enabling + InfiniBand support is required for all RDMA devices (IB, iWARP, etc.)]. + + Enable the appropriate IB HCA support (mlx4, mthca, ehca, ipath, etc.) or + iWARP adapter support (amso, cxgb3, etc.). + + If you are using InfiniBand, be sure to enable IP-over-InfiniBand support. + + - Configure the NFS client and server + + Your kernel configuration must also have NFS file system support and/or + NFS server support enabled. These and other NFS related configuration + options can be found under File Systems -> Network File Systems. + + - Build, install, reboot + + The NFS/RDMA code will be enabled automatically if NFS and RDMA + are turned on. The NFS/RDMA client and server are configured via the hidden + SUNRPC_XPRT_RDMA config option that depends on SUNRPC and INFINIBAND.

So instead of using an input source selector like on other ALC268 models, the mic automute automatically switch between captures.

These codecs can have multiple SPDIF devices, but currently we handle only one SPDIF. If any real devices with two SPDIF interfaces (likely one for SPDIF and one for HDMI), we'll fix this rightly. Otherwise, these codecs are pretty similar with AD1988.

This patch moves saa7134_tuner_callback to saa7134-cards, originally used only by tda8290 DVB-S boards. The callback was made more generic to support other tuners. Currently, it supports both tda8290 and xc2028/xc3028 tuners. Added also the basis for xc5000 tuner callback.

The card has sixteen (16) BNC video inputs, four of them on the board itself and twelve on three daughter-cards. It has a single bt878 chip, no tuner and what looks like and audio input. After doing some research I managed to get only eight channels working by forcing card=125 and those DID NOT match channels 0-7 on the card, and no audio. Based on what was working for card=125, I added the card definition block, added a specific muxsel routine and got the card working fully with xawtv, where the sixteen channels show up as Composite0 to Composite15, matching the channel labels in the card and daughter-cards. I have made no efforts yet to get audio working, but would appreciate any pointers.

This patch adds proper support for radio, video, s-video, composite and ATSC. However, support for radio and video depends on having s5h1409 i2c gate open, otherwise, xc30x8 chip won't be visible. For a better support, some rework is needed on cx88 driver, to allow adding xc30x8 to i2c bus without sending i2c 0 byte reading to 0xc2 address. Thanks to Vanessa Ezekowitz for helping to figure out the proper parameters for s5h1409 and the GPIO pins used by each configuration.

This has almost no effect, since those tags shouldn't be used; 2) DIBCOM52 were using a wrong IF. It should be 5200, instead of 5700; 3) seek_firmware were wanting an exact match for firmware type. This is wrong. As result, no SCODE firmware were loaded; 4) A few files were including the wrong file for seeking demod firmwares; 5) XC3028_FE_DEFAULT can be used, if user doesn't want to load a firmware. However, this weren't documentated. This feature require more testing.

These two kinds of +callbacks are completely independent of each other. Information on the +completion callback can be found in Documentation/usb/URB.txt. + +The callbacks defined in the driver structure are: + +1.

Device level operations: + + * @pre_reset: Called when the device is about to be reset. + * @post_reset: Called after the device has been reset + +The ioctl interface (2) should be used only if you have a very good +reason. Sysfs is preferred these days. The PM callbacks are covered +separately in Documentation/usb/power-management.txt. + +Calling conventions +=================== + +All callbacks are mutually exclusive. There's no need for locking +against other USB callbacks. All callbacks are called from a task +context. You may sleep. However, it is important that all sleeps have a +small fixed upper limit in time. In particular you must not call out to +user space and await results. + +Hotplugging callbacks +===================== + +These callbacks are intended to associate and disassociate a driver with +an interface. A driver's bond to an interface is exclusive. + +The probe() callback +-------------------- + +int (*probe) (struct usb_interface *intf, + const struct usb_device_id *id); + +Accept or decline an interface. If you accept the device return 0, +otherwise -ENODEV or -ENXIO. Other error codes should be used only if a +genuine error occurred during initialisation which prevented a driver +from accepting a device that would else have been accepted. +You are strongly encouraged to use usbcore'sfacility, +usb_set_intfdata(), to associate a data structure with an interface, so +that you know which internal state and identity you associate with a +particular interface. The device will not be suspended and you may do IO +to the interface you are called for and endpoint 0 of the device. Device +initialisation that doesn't take too long is a good idea here. + +The disconnect() callback +------------------------- + +void (*disconnect) (struct usb_interface *intf); + +This callback is a signal to break any connection with an interface. +You are not allowed any IO to a device after returning from this +callback. You also may not do any other operation that may interfere +with another driver bound the interface, eg. a power management +operation. +If you are called due to a physical disconnection, all your URBs will be +killed by usbcore. Note that in this case disconnect will be called some +time after the physical disconnection. Thus your driver must be prepared +to deal with failing IO even prior to the callback. + +Device level callbacks +====================== + +pre_reset +--------- + +int (*pre_reset)(struct usb_interface *intf); + +Another driver or user space is triggering a reset on the device which +contains the interface passed as an argument. Cease IO and save any +device state you need to restore. + +If you need to allocate memory here, use GFP_NOIO or GFP_ATOMIC, if you +are in atomic context. + +post_reset +---------- + +int (*post_reset)(struct usb_interface *intf); + +The reset has completed. Restore any saved device state and begin +using the device again. + +If you need to allocate memory here, use GFP_NOIO or GFP_ATOMIC, if you +are in atomic context. + +Call sequences +============== + +No callbacks other than probe will be invoked for an interface +that isn't bound to your driver. + +Probe will never be called for an interface bound to a driver. +Hence following a successful probe, disconnect will be called +before there is another probe for the same interface. + +Once your driver is bound to an interface, disconnect can be +called at any time except in between pre_reset and post_reset. +pre_reset is always followed by post_reset, even if the reset +failed or the device has been unplugged. + +suspend is always followed by one of: resume, reset_resume, or +disconnect. -- cgit v1.2.3 From f62220d3a9ccb879c3f90f845ae57b724b7bbb62 Mon Sep 17 00:00:00 2001 From: Andy Fleming Date: Fri, 18 Apr 2008 17:29:54 -0500 Subject: phylib: Add support for board-level PHY fixups Sometimes the specific interaction between the platform and the PHY requires special handling.

Only the host kernel runs in supervisor mode. +Executing privileged instructions in the guest traps into KVM (in the host +kernel), where we decode and emulate them. Through this technique, unmodified +440 Linux kernels can be run (slowly) as guests. Future performance work will +focus on reducing the overhead and frequency of these traps. + +The usual code flow is started from userspace invoking an "run" ioctl, which +causes KVM to switch into guest context. We use IVPR to hijack the host +interrupt vectors while running the guest, which allows us to direct all +interrupts to kvmppc_handle_interrupt(). At this point, we could either +- handle the interrupt completely (e.g. emulate "mtspr SPRG0"), or +- let the host interrupt handler run (e.g. when the decrementer fires), or +- return to host userspace (e.g. when the guest performs device MMIO) + +Address spaces: We take advantage of the fact that Linux doesn't use the AS=1 +address space (in host or guest), which gives us virtual address space to use +for guest mappings. While the guest is running, the host kernel remains mapped +in AS=0, but the guest can only use AS=1 mappings. + +TLB entries: The TLB entries covering the host linear mapping remain +present while running the guest. This reduces the overhead of lightweight +exits, which are handled by KVM running in the host kernel. We keep three +copies of the TLB: + - guest TLB: contents of the TLB as the guest sees it + - shadow TLB: the TLB that is actually in hardware while guest is running + - host TLB: to restore TLB state when context switching guest -> host +When a TLB miss occurs because a mapping was not present in the shadow TLB, +but was present in the guest TLB, KVM handles the fault without invoking the +guest. Large guest pages are backed by multiple 4KB shadow pages through this +mechanism. + +IO: MMIO and DCR accesses are emulated by userspace. We use virtio for network +and block IO, so those drivers must be enabled in the guest. It's possible +that some qemu device emulation (e.g. e1000 or rtl8139) may also work with +little effort. diff --git a/arch/powerpc/Kconfig b/arch/powerpc/Kconfig index 20f45a8b87e3..4e40c122bf26 100644 --- a/arch/powerpc/Kconfig +++ b/arch/powerpc/Kconfig @@ -803,3 +803,4 @@ config PPC_CLOCK config PPC_LIB_RHEAP bool +source "arch/powerpc/kvm/Kconfig" diff --git a/arch/powerpc/Kconfig.debug b/arch/powerpc/Kconfig.debug index a86d8d853214..807a2dce6263 100644 --- a/arch/powerpc/Kconfig.debug +++ b/arch/powerpc/Kconfig.debug @@ -151,6 +151,9 @@ config BOOTX_TEXT config PPC_EARLY_DEBUG bool "Early debugging (dangerous)" + # PPC_EARLY_DEBUG on 440 leaves AS=1 mappings above the TLB high water + # mark, which doesn't work with current 440 KVM. + depends on !KVM help Say Y to enable some early debugging facilities that may be available for your processor/board combination.

Provide a new sysfs field total_objects which shows the total objects that the allocated slabs of a slabcache could hold. Add a max field that holds the largest slab order that was ever used for a slab cache.

As the per-node zonelist is already being filtered based on a zone id, this patch adds a version of __alloc_pages() that takes a nodemask for further filtering. This eliminates the need for MPOL_BIND to create a custom zonelist. A positive benefit of this is that allocations using MPOL_BIND now use the local node's distance-ordered zonelist instead of a custom node-id-ordered zonelist. I.e., pages will be allocated from the closest allowed node with available memory.

In other areas, further inspection reveals that I botched the unref for interleave policies. A separate patch, suitable for upstream/stable trees, fixes up the known errors in the previous attempt to fix reference counting. This patch reworks the memory policy referencing counting and, one hopes, simplifies the code. Maybe I'll get it right this time. See the update to the numa_memory_policy.txt document for a discussion of memory policy reference counting that motivates this patch. Summary: Lookup of mempolicy, based on (vma, address) need only add a reference for shared policy, and we need only unref the policy when finished for shared policies. So, this patch backs out all of the unneeded extra reference counting added by my previous attempt. It then unrefs only shared policies when we're finished with them, using the mpol_cond_put() [conditional put] helper function introduced by this patch. Note that shmem_swapin() calls read_swap_cache_async() with a dummy vma containing just the policy. read_swap_cache_async() can call alloc_page_vma() multiple times, so we can't let alloc_page_vma() unref the shared policy in this case. To avoid this, we make a copy of any non-null shared policy and remove the MPOL_F_SHARED flag from the copy. This copy occurs before reading a page [or multiple pages] from swap, so the overhead should not be an issue here. I introduced a new static inline function "mpol_cond_copy()" to copy the shared policy to an on-stack policy and remove the flags that would require a conditional free. The current implementation of mpol_cond_copy() assumes that the struct mempolicy contains no pointers to dynamically allocated structures that must be duplicated or reference counted during copy.

Thus, there is no possibility + of a task or thread freeing a policy while another task or thread is + querying it. + +3) Page allocation usage of task or vma policy occurs in the fault path where + we hold them mmap_sem for read. Again, because replacing the task or vma + policy requires that the mmap_sem be held for write, the policy can't be + freed out from under us while we're using it for page allocation. + +4) Shared policies require special consideration. One task can replace a + shared memory policy while another task, with a distinct mmap_sem, is + querying or allocating a page based on the policy. To resolve this + potential race, the shared policy infrastructure adds an extra reference + to the shared policy during lookup while holding a spin lock on the shared + policy management structure. This requires that we drop this extra + reference when we're finished "using" the policy. We must drop the + extra reference on shared policies in the same query/allocation paths + used for non-shared policies. For this reason, shared policies are marked + as such, and the extra reference is dropped "conditionally"--i.e., only + for shared policies. + + Because of this extra reference counting, and because we must lookup + shared policies in a tree structure under spinlock, shared policies are + more expensive to use in the page allocation path. This is expecially + true for shared policies on shared memory regions shared by tasks running + on different NUMA nodes. This extra overhead can be avoided by always + falling back to task or system default policy for shared memory regions, + or by prefaulting the entire shared memory region into memory and locking + it down.

This causes any use of that policy to "fall back" to the next most specific policy scope. The only use of MPOL_DEFAULT to mean "local allocation" is in the system default policy. This requires extra checks/cases for MPOL_DEFAULT in many mempolicy.c functions. There is another, "preferred" way to specify local allocation via the APIs. That is using the MPOL_PREFERRED policy mode with an empty nodemask. Internally, the empty nodemask gets converted to a preferred_node id of '-1'. All internal usage of MPOL_PREFERRED will convert the '-1' to the id of the node local to the cpu where the allocation occurs. System default policy, except during boot, is hard-coded to "local allocation". By using the MPOL_PREFERRED mode with a negative value of preferred node for system default policy, MPOL_DEFAULT will never occur in the 'policy' member of a struct mempolicy. Thus, we can remove all checks for MPOL_DEFAULT when converting policy to a node id/zonelist in the allocation paths. In slab_node() return local node id when policy pointer is NULL. No need to set a pol value to take the switch default. Replace switch default with BUG()--i.e., shouldn't happen. With this patch MPOL_DEFAULT is only used in the APIs, including internal calls to do_set_mempolicy() and in the display of policy in /proc//numa_maps. It always means "fall back" to the the next most specific policy scope. This simplifies the description of memory policies quite a bit, with no visible change in behavior. get_mempolicy() continues to return MPOL_DEFAULT and an empty nodemask when the requested policy [task or vma/shared] is NULL. These are the values one would supply via set_mempolicy() or mbind() to achieve that condition--default behavior. This patch updates Documentation to reflect this change.

Because of the variable size of the mempolicy structure [based on size of nodemasks], the preferred_node may be in a different cacheline from the mode. This can result in accessing an extra cacheline in the normal case of system default policy. Suspect this is the cause of an observed 2-3% slowdown in page fault testing relative to kernel without this patch series. To alleviate this, use an internal mode flag, MPOL_F_LOCAL in the mempolicy flags member which is guaranteed [?] to be in the same cacheline as the mode itself. Verified that reworked mempolicy now performs slightly better on 25-rc8-mm1 for both anon and shmem segments with system default and vma [preferred local] policy.

The switch to the ACPI backlight mode in the firmware is designed to be safe to use only as an one way trapdoor. One is not to force the firmware to switch back to "DOS/bootloader" mode except by rebooting. The mode switch itself is performed by calling any of the ACPI _BCL methods at least once. When in ACPI mode, the backlight firmware just issues (standard) events for the brightness up/down hot key presses along with the non-standard HKEY events which thinkpad-acpi traps, and doesn't touch the hardware. thinkpad-acpi will: 1. Place the ThinkPad firmware in ACPI backlight control mode if one is available 2. Suppress HKEY backlight change notifications by default to avoid double-reporting when ACPI video is loaded when the ThinkPad is in ACPI backlight control mode 3. Urge the user to load the ACPI video driver The user is free to use either the ACPI video driver to get the brightness key events, or to override the thinkpad-acpi default hotkey mask to get them from thinkpad-acpi as well (this will result in duplicate events if ACPI video is loaded, so let's hope distros won't screw this up). Provided userspace is sane, all should work (and *keep* working), which is more that can be said about the non-ACPI mode of the new Lenovo ThinkPad BIOSes when coupled to current userspace and X.org drivers. Full guidelines for backlight hot key reporting and use of the thinkpad-acpi backlight interface have been added to the documentation.

We were using "tpacpi" in symbols already, but this shorthand was not visible to userland. Document that the driver will use tpacpi as a short hand where necessary, and use it to name the kernel thread for NVRAM polling (now named "ktpacpi_nvramd"). Also, register a module alias with the shorthand. One can refer to the module using the shorthand name.
