From 8e552c36d90c03d2cabf5373788998966751b609 Mon Sep 17 00:00:00 2001 From: Andres Salomon Date: Mon, 12 May 2008 21:46:29 -0400 Subject: power_supply: add CHARGE_COUNTER property and olpc_battery support for it This adds PROP_CHARGE_COUNTER to the power supply class (documenting it as well). The OLPC battery driver uses this for spitting out its ACR values (in uAh). We have some rounding errors (the data sheet claims 416.7, the math actually works out to 416.666667, so we're forced to choose between overflows or precision loss. I chose precision loss, and stuck w/ data sheet values), but I don't think anyone will care that much.

Interrupt-remapping must be enabled before enabling x2apic, this is needed to ensure that IO interrupts continue to work properly after the cpu mode is changed to x2apic(which uses 32bit extended physical/cluster apic id). On systems where apicid's are > 255, BIOS can handover the control to OS in x2apic mode. Or if the OS handover was in legacy xapic mode, check if it is capable of x2apic mode. And if we succeed in enabling Interrupt-remapping, then we can enable x2apic mode in the CPU.

Some of its options are also +relevant to the boot loader itself, see "special command line options" +below. + +The kernel command line is a null-terminated string. The maximum +length can be retrieved from the field cmdline_size. Before protocol +version 2.06, the maximum was 255 characters. A string that is too +long will be automatically truncated by the kernel. + +If the boot protocol version is 2.02 or later, the address of the +kernel command line is given by the header field cmd_line_ptr (see +above.) This address can be anywhere between the end of the setup +heap and 0xA0000. + +If the protocol version is *not* 2.02 or higher, the kernel +command line is entered using the following protocol: + + At offset 0x0020 (word), "cmd_line_magic", enter the magic + number 0xA33F. + + At offset 0x0022 (word), "cmd_line_offset", enter the offset + of the kernel command line (relative to the start of the + real-mode kernel). + + The kernel command line *must* be within the memory region + covered by setup_move_size, so you may need to adjust this + field. + + +**** MEMORY LAYOUT OF THE REAL-MODE CODE + +The real-mode code requires a stack/heap to be set up, as well as +memory allocated for the kernel command line. This needs to be done +in the real-mode accessible memory in bottom megabyte. + +It should be noted that modern machines often have a sizable Extended +BIOS Data Area (EBDA). As a result, it is advisable to use as little +of the low megabyte as possible. + +Unfortunately, under the following circumstances the 0x90000 memory +segment has to be used: + + - When loading a zImage kernel ((loadflags & 0x01) == 0). + - When loading a 2.01 or earlier boot protocol kernel. + + -> For the 2.00 and 2.01 boot protocols, the real-mode code + can be loaded at another address, but it is internally + relocated to 0x90000. For the "old" protocol, the + real-mode code must be loaded at 0x90000. + +When loading at 0x90000, avoid using memory above 0x9a000. + +For boot protocol 2.02 or higher, the command line does not have to be +located in the same 64K segment as the real-mode setup code; it is +thus permitted to give the stack/heap the full 64K segment and locate +the command line above it. + +The kernel command line should not be located below the real-mode +code, nor should it be located in high memory. + + +**** SAMPLE BOOT CONFIGURATION + +As a sample configuration, assume the following layout of the real +mode segment: + + When loading below 0x90000, use the entire segment: + + 0x0000-0x7fff Real mode kernel + 0x8000-0xdfff Stack and heap + 0xe000-0xffff Kernel command line + + When loading at 0x90000 OR the protocol version is 2.01 or earlier: + + 0x0000-0x7fff Real mode kernel + 0x8000-0x97ff Stack and heap + 0x9800-0x9fff Kernel command line + +Such a boot loader should enter the following fields in the header: + + unsigned long base_ptr; /* base address for real-mode segment */ + + if ( setup_sects == 0 ) { + setup_sects = 4; + } + + if ( protocol >= 0x0200 ) { + type_of_loader = ; + if ( loading_initrd ) { + ramdisk_image = ; + ramdisk_size = ; + } + + if ( protocol >= 0x0202 && loadflags & 0x01 ) + heap_end = 0xe000; + else + heap_end = 0x9800; + + if ( protocol >= 0x0201 ) { + heap_end_ptr = heap_end - 0x200; + loadflags |= 0x80; /* CAN_USE_HEAP */ + } + + if ( protocol >= 0x0202 ) { + cmd_line_ptr = base_ptr + heap_end; + strcpy(cmd_line_ptr, cmdline); + } else { + cmd_line_magic = 0xA33F; + cmd_line_offset = heap_end; + setup_move_size = heap_end + strlen(cmdline)+1; + strcpy(base_ptr+cmd_line_offset, cmdline); + } + } else { + /* Very old kernel */ + + heap_end = 0x9800; + + cmd_line_magic = 0xA33F; + cmd_line_offset = heap_end; + + /* A very old kernel MUST have its real-mode code + loaded at 0x90000 */ + + if ( base_ptr != 0x90000 ) { + /* Copy the real-mode kernel */ + memcpy(0x90000, base_ptr, (setup_sects+1)*512); + base_ptr = 0x90000; /* Relocated */ + } + + strcpy(0x90000+cmd_line_offset, cmdline); + + /* It is recommended to clear memory up to the 32K mark */ + memset(0x90000 + (setup_sects+1)*512, 0, + (64-(setup_sects+1))*512); + } + + +**** LOADING THE REST OF THE KERNEL + +The 32-bit (non-real-mode) kernel starts at offset (setup_sects+1)*512 +in the kernel file (again, if setup_sects == 0 the real value is 4.) +It should be loaded at address 0x10000 for Image/zImage kernels and +0x100000 for bzImage kernels. + +The kernel is a bzImage kernel if the protocol >= 2.00 and the 0x01 +bit (LOAD_HIGH) in the loadflags field is set: + + is_bzImage = (protocol >= 0x0200) && (loadflags & 0x01); + load_address = is_bzImage ? 0x100000 : 0x10000; + +Note that Image/zImage kernels can be up to 512K in size, and thus use +the entire 0x10000-0x90000 range of memory. This means it is pretty +much a requirement for these kernels to load the real-mode part at +0x90000. bzImage kernels allow much more flexibility. + + +**** SPECIAL COMMAND LINE OPTIONS + +If the command line provided by the boot loader is entered by the +user, the user may expect the following command line options to work. +They should normally not be deleted from the kernel command line even +though not all of them are actually meaningful to the kernel. Boot +loader authors who need additional command line options for the boot +loader itself should get them registered in +Documentation/kernel-parameters.txt to make sure they will not +conflict with actual kernel options now or in the future. + + vga= + here is either an integer (in C notation, either + decimal, octal, or hexadecimal) or one of the strings + "normal" (meaning 0xFFFF), "ext" (meaning 0xFFFE) or "ask" + (meaning 0xFFFD). This value should be entered into the + vid_mode field, as it is used by the kernel before the command + line is parsed. + + mem= + is an integer in C notation optionally followed by + (case insensitive) K, M, G, T, P or E (meaning << 10, << 20, + << 30, << 40, << 50 or << 60). This specifies the end of + memory to the kernel. This affects the possible placement of + an initrd, since an initrd should be placed near end of + memory. Note that this is an option to *both* the kernel and + the bootloader! + + initrd= + An initrd should be loaded. The meaning of is + obviously bootloader-dependent, and some boot loaders + (e.g. LILO) do not have such a command. + +In addition, some boot loaders add the following options to the +user-specified command line: + + BOOT_IMAGE= + The boot image which was loaded. Again, the meaning of + is obviously bootloader-dependent. + + auto + The kernel was booted without explicit user intervention. + +If these options are added by the boot loader, it is highly +recommended that they are located *first*, before the user-specified +or configuration-specified command line. Otherwise, "init=/bin/sh" +gets confused by the "auto" option. + + +**** RUNNING THE KERNEL + +The kernel is started by jumping to the kernel entry point, which is +located at *segment* offset 0x20 from the start of the real mode +kernel. This means that if you loaded your real-mode kernel code at +0x90000, the kernel entry point is 9020:0000. + +At entry, ds = es = ss should point to the start of the real-mode +kernel code (0x9000 if the code is loaded at 0x90000), sp should be +set up properly, normally pointing to the top of the heap, and +interrupts should be disabled. Furthermore, to guard against bugs in +the kernel, it is recommended that the boot loader sets fs = gs = ds = +es = ss. + +In our example from above, we would do: + + /* Note: in the case of the "old" kernel protocol, base_ptr must + be == 0x90000 at this point; see the previous sample code */ + + seg = base_ptr >> 4; + + cli(); /* Enter with interrupts disabled! */ + + /* Set up the real-mode kernel stack */ + _SS = seg; + _SP = heap_end; + + _DS = _ES = _FS = _GS = seg; + jmp_far(seg+0x20, 0); /* Run the kernel */ + +If your boot sector accesses a floppy drive, it is recommended to +switch off the floppy motor before running the kernel, since the +kernel boot leaves interrupts off and thus the motor will not be +switched off, especially if the loaded kernel has the floppy driver as +a demand-loaded module! + + +**** ADVANCED BOOT LOADER HOOKS + +If the boot loader runs in a particularly hostile environment (such as +LOADLIN, which runs under DOS) it may be impossible to follow the +standard memory location requirements. Such a boot loader may use the +following hooks that, if set, are invoked by the kernel at the +appropriate time. The use of these hooks should probably be +considered an absolutely last resort! + +IMPORTANT: All the hooks are required to preserve %esp, %ebp, %esi and +%edi across invocation. + + realmode_swtch: + A 16-bit real mode far subroutine invoked immediately before + entering protected mode. The default routine disables NMI, so + your routine should probably do so, too. + + code32_start: + A 32-bit flat-mode routine *jumped* to immediately after the + transition to protected mode, but before the kernel is + uncompressed. No segments, except CS, are guaranteed to be + set up (current kernels do, but older ones do not); you should + set them up to BOOT_DS (0x18) yourself. + + After completing your hook, you should jump to the address + that was in this field before your boot loader overwrote it + (relocated, if appropriate.) + + +**** 32-bit BOOT PROTOCOL + +For machine with some new BIOS other than legacy BIOS, such as EFI, +LinuxBIOS, etc, and kexec, the 16-bit real mode setup code in kernel +based on legacy BIOS can not be used, so a 32-bit boot protocol needs +to be defined. + +In 32-bit boot protocol, the first step in loading a Linux kernel +should be to setup the boot parameters (struct boot_params, +traditionally known as "zero page"). The memory for struct boot_params +should be allocated and initialized to all zero. Then the setup header +from offset 0x01f1 of kernel image on should be loaded into struct +boot_params and examined. The end of setup header can be calculated as +follow: + + 0x0202 + byte value at offset 0x0201 + +In addition to read/modify/write the setup header of the struct +boot_params as that of 16-bit boot protocol, the boot loader should +also fill the additional fields of the struct boot_params as that +described in zero-page.txt. + +After setupping the struct boot_params, the boot loader can load the +32/64-bit kernel in the same way as that of 16-bit boot protocol. + +In 32-bit boot protocol, the kernel is started by jumping to the +32-bit kernel entry point, which is the start address of loaded +32/64-bit kernel. + +At entry, the CPU must be in 32-bit protected mode with paging +disabled; a GDT must be loaded with the descriptors for selectors +__BOOT_CS(0x10) and __BOOT_DS(0x18); both descriptors must be 4G flat +segment; __BOOS_CS must have execute/read permission, and __BOOT_DS +must have read/write permission; CS must be __BOOT_CS and DS, ES, SS +must be __BOOT_DS; interrupt must be disabled; %esi must hold the base +address of the struct boot_params; %ebp, %edi and %ebx must be zero. diff --git a/Documentation/x86/i386/boot.txt b/Documentation/x86/i386/boot.txt deleted file mode 100644 index 147bfe511cdd..000000000000 --- a/Documentation/x86/i386/boot.txt +++ /dev/null @@ -1,900 +0,0 @@ - THE LINUX/x86 BOOT PROTOCOL - --------------------------- - -On the x86 platform, the Linux kernel uses a rather complicated boot -convention.

For -zImage or old bzImage kernels, which need data written into the -0x90000 segment, the boot loader should make sure not to use memory -above the 0x9A000 point; too many BIOSes will break above that point. - -For a modern bzImage kernel with boot protocol version >= 2.02, a -memory layout like the following is suggested: - - ~ ~ - | Protected-mode kernel | -100000 +------------------------+ - | I/O memory hole | -0A0000 +------------------------+ - | Reserved for BIOS | Leave as much as possible unused - ~ ~ - | Command line | (Can also be below the X+10000 mark) -X+10000 +------------------------+ - | Stack/heap | For use by the kernel real-mode code. -X+08000 +------------------------+ - | Kernel setup | The kernel real-mode code. - | Kernel boot sector | The kernel legacy boot sector. -X +------------------------+ - | Boot loader | <- Boot sector entry point 0000:7C00 -001000 +------------------------+ - | Reserved for MBR/BIOS | -000800 +------------------------+ - | Typically used by MBR | -000600 +------------------------+ - | BIOS use only | -000000 +------------------------+ - -... where the address X is as low as the design of the boot loader -permits. - - -**** THE REAL-MODE KERNEL HEADER - -In the following text, and anywhere in the kernel boot sequence, "a -sector" refers to 512 bytes.

For boot protocols 2.02 or earlier, this - field is not present, and the maximum address is 0x37FFFFFF. (This - address is defined as the address of the highest safe byte, so if - your ramdisk is exactly 131072 bytes long and this field is - 0x37FFFFFF, you can start your ramdisk at 0x37FE0000.) - -Field name: kernel_alignment -Type: read (reloc) -Offset/size: 0x230/4 -Protocol: 2.05+ - - Alignment unit required by the kernel (if relocatable_kernel is true.) - -Field name: relocatable_kernel -Type: read (reloc) -Offset/size: 0x234/1 -Protocol: 2.05+ - - If this field is nonzero, the protected-mode part of the kernel can - be loaded at any address that satisfies the kernel_alignment field. - After loading, the boot loader must set the code32_start field to - point to the loaded code, or to a boot loader hook. - -Field name: cmdline_size -Type: read -Offset/size: 0x238/4 -Protocol: 2.06+ - - The maximum size of the command line without the terminating - zero. This means that the command line can contain at most - cmdline_size characters. With protocol version 2.05 and earlier, the - maximum size was 255. - -Field name: hardware_subarch -Type: write (optional, defaults to x86/PC) -Offset/size: 0x23c/4 -Protocol: 2.07+ - - In a paravirtualized environment the hardware low level architectural - pieces such as interrupt handling, page table handling, and - accessing process control registers needs to be done differently. - - This field allows the bootloader to inform the kernel we are in one - one of those environments. - - 0x00000000 The default x86/PC environment - 0x00000001 lguest - 0x00000002 Xen - -Field name: hardware_subarch_data -Type: write (subarch-dependent) -Offset/size: 0x240/8 -Protocol: 2.07+ - - A pointer to data that is specific to hardware subarch - This field is currently unused for the default x86/PC environment, - do not modify. - -Field name: payload_offset -Type: read -Offset/size: 0x248/4 -Protocol: 2.08+ - - If non-zero then this field contains the offset from the end of the - real-mode code to the payload. - - The payload may be compressed.

This is used to define a more extensible boot - parameters passing mechanism. The definition of struct setup_data is - as follow: - - struct setup_data { - u64 next; - u32 type; - u32 len; - u8 data[0]; - }; - - Where, the next is a 64-bit physical pointer to the next node of - linked list, the next field of the last node is 0; the type is used - to identify the contents of data; the len is the length of data - field; the data holds the real payload. - - This list may be modified at a number of points during the bootup - process. Therefore, when modifying this list one should always make - sure to consider the case where the linked list already contains - entries. - - -**** THE IMAGE CHECKSUM - -From boot protocol version 2.08 onwards the CRC-32 is calculated over -the entire file using the characteristic polynomial 0x04C11DB7 and an -initial remainder of 0xffffffff. The checksum is appended to the -file; therefore the CRC of the file up to the limit specified in the -syssize field of the header is always 0. - - -**** THE KERNEL COMMAND LINE - -The kernel command line has become an important way for the boot -loader to communicate with the kernel. Some of its options are also -relevant to the boot loader itself, see "special command line options" -below. - -The kernel command line is a null-terminated string. The maximum -length can be retrieved from the field cmdline_size. Before protocol -version 2.06, the maximum was 255 characters. A string that is too -long will be automatically truncated by the kernel. - -If the boot protocol version is 2.02 or later, the address of the -kernel command line is given by the header field cmd_line_ptr (see -above.) This address can be anywhere between the end of the setup -heap and 0xA0000. - -If the protocol version is *not* 2.02 or higher, the kernel -command line is entered using the following protocol: - - At offset 0x0020 (word), "cmd_line_magic", enter the magic - number 0xA33F. - - At offset 0x0022 (word), "cmd_line_offset", enter the offset - of the kernel command line (relative to the start of the - real-mode kernel). - - The kernel command line *must* be within the memory region - covered by setup_move_size, so you may need to adjust this - field. - - -**** MEMORY LAYOUT OF THE REAL-MODE CODE - -The real-mode code requires a stack/heap to be set up, as well as -memory allocated for the kernel command line. This needs to be done -in the real-mode accessible memory in bottom megabyte. - -It should be noted that modern machines often have a sizable Extended -BIOS Data Area (EBDA). As a result, it is advisable to use as little -of the low megabyte as possible. - -Unfortunately, under the following circumstances the 0x90000 memory -segment has to be used: - - - When loading a zImage kernel ((loadflags & 0x01) == 0). - - When loading a 2.01 or earlier boot protocol kernel. - - -> For the 2.00 and 2.01 boot protocols, the real-mode code - can be loaded at another address, but it is internally - relocated to 0x90000. For the "old" protocol, the - real-mode code must be loaded at 0x90000. - -When loading at 0x90000, avoid using memory above 0x9a000. - -For boot protocol 2.02 or higher, the command line does not have to be -located in the same 64K segment as the real-mode setup code; it is -thus permitted to give the stack/heap the full 64K segment and locate -the command line above it. - -The kernel command line should not be located below the real-mode -code, nor should it be located in high memory. - - -**** SAMPLE BOOT CONFIGURATION - -As a sample configuration, assume the following layout of the real -mode segment: - - When loading below 0x90000, use the entire segment: - - 0x0000-0x7fff Real mode kernel - 0x8000-0xdfff Stack and heap - 0xe000-0xffff Kernel command line - - When loading at 0x90000 OR the protocol version is 2.01 or earlier: - - 0x0000-0x7fff Real mode kernel - 0x8000-0x97ff Stack and heap - 0x9800-0x9fff Kernel command line - -Such a boot loader should enter the following fields in the header: - - unsigned long base_ptr; /* base address for real-mode segment */ - - if ( setup_sects == 0 ) { - setup_sects = 4; - } - - if ( protocol >= 0x0200 ) { - type_of_loader = ; - if ( loading_initrd ) { - ramdisk_image = ; - ramdisk_size = ; - } - - if ( protocol >= 0x0202 && loadflags & 0x01 ) - heap_end = 0xe000; - else - heap_end = 0x9800; - - if ( protocol >= 0x0201 ) { - heap_end_ptr = heap_end - 0x200; - loadflags |= 0x80; /* CAN_USE_HEAP */ - } - - if ( protocol >= 0x0202 ) { - cmd_line_ptr = base_ptr + heap_end; - strcpy(cmd_line_ptr, cmdline); - } else { - cmd_line_magic = 0xA33F; - cmd_line_offset = heap_end; - setup_move_size = heap_end + strlen(cmdline)+1; - strcpy(base_ptr+cmd_line_offset, cmdline); - } - } else { - /* Very old kernel */ - - heap_end = 0x9800; - - cmd_line_magic = 0xA33F; - cmd_line_offset = heap_end; - - /* A very old kernel MUST have its real-mode code - loaded at 0x90000 */ - - if ( base_ptr != 0x90000 ) { - /* Copy the real-mode kernel */ - memcpy(0x90000, base_ptr, (setup_sects+1)*512); - base_ptr = 0x90000; /* Relocated */ - } - - strcpy(0x90000+cmd_line_offset, cmdline); - - /* It is recommended to clear memory up to the 32K mark */ - memset(0x90000 + (setup_sects+1)*512, 0, - (64-(setup_sects+1))*512); - } - - -**** LOADING THE REST OF THE KERNEL - -The 32-bit (non-real-mode) kernel starts at offset (setup_sects+1)*512 -in the kernel file (again, if setup_sects == 0 the real value is 4.) -It should be loaded at address 0x10000 for Image/zImage kernels and -0x100000 for bzImage kernels. - -The kernel is a bzImage kernel if the protocol >= 2.00 and the 0x01 -bit (LOAD_HIGH) in the loadflags field is set: - - is_bzImage = (protocol >= 0x0200) && (loadflags & 0x01); - load_address = is_bzImage ? 0x100000 : 0x10000; - -Note that Image/zImage kernels can be up to 512K in size, and thus use -the entire 0x10000-0x90000 range of memory. This means it is pretty -much a requirement for these kernels to load the real-mode part at -0x90000. bzImage kernels allow much more flexibility. - - -**** SPECIAL COMMAND LINE OPTIONS - -If the command line provided by the boot loader is entered by the -user, the user may expect the following command line options to work. -They should normally not be deleted from the kernel command line even -though not all of them are actually meaningful to the kernel. Boot -loader authors who need additional command line options for the boot -loader itself should get them registered in -Documentation/kernel-parameters.txt to make sure they will not -conflict with actual kernel options now or in the future. - - vga= - here is either an integer (in C notation, either - decimal, octal, or hexadecimal) or one of the strings - "normal" (meaning 0xFFFF), "ext" (meaning 0xFFFE) or "ask" - (meaning 0xFFFD). This value should be entered into the - vid_mode field, as it is used by the kernel before the command - line is parsed. - - mem= - is an integer in C notation optionally followed by - (case insensitive) K, M, G, T, P or E (meaning << 10, << 20, - << 30, << 40, << 50 or << 60). This specifies the end of - memory to the kernel. This affects the possible placement of - an initrd, since an initrd should be placed near end of - memory. Note that this is an option to *both* the kernel and - the bootloader! - - initrd= - An initrd should be loaded. The meaning of is - obviously bootloader-dependent, and some boot loaders - (e.g. LILO) do not have such a command. - -In addition, some boot loaders add the following options to the -user-specified command line: - - BOOT_IMAGE= - The boot image which was loaded. Again, the meaning of - is obviously bootloader-dependent. - - auto - The kernel was booted without explicit user intervention. - -If these options are added by the boot loader, it is highly -recommended that they are located *first*, before the user-specified -or configuration-specified command line. Otherwise, "init=/bin/sh" -gets confused by the "auto" option. - - -**** RUNNING THE KERNEL - -The kernel is started by jumping to the kernel entry point, which is -located at *segment* offset 0x20 from the start of the real mode -kernel. This means that if you loaded your real-mode kernel code at -0x90000, the kernel entry point is 9020:0000. - -At entry, ds = es = ss should point to the start of the real-mode -kernel code (0x9000 if the code is loaded at 0x90000), sp should be -set up properly, normally pointing to the top of the heap, and -interrupts should be disabled. Furthermore, to guard against bugs in -the kernel, it is recommended that the boot loader sets fs = gs = ds = -es = ss. - -In our example from above, we would do: - - /* Note: in the case of the "old" kernel protocol, base_ptr must - be == 0x90000 at this point; see the previous sample code */ - - seg = base_ptr >> 4; - - cli(); /* Enter with interrupts disabled! */ - - /* Set up the real-mode kernel stack */ - _SS = seg; - _SP = heap_end; - - _DS = _ES = _FS = _GS = seg; - jmp_far(seg+0x20, 0); /* Run the kernel */ - -If your boot sector accesses a floppy drive, it is recommended to -switch off the floppy motor before running the kernel, since the -kernel boot leaves interrupts off and thus the motor will not be -switched off, especially if the loaded kernel has the floppy driver as -a demand-loaded module! - - -**** ADVANCED BOOT LOADER HOOKS - -If the boot loader runs in a particularly hostile environment (such as -LOADLIN, which runs under DOS) it may be impossible to follow the -standard memory location requirements. Such a boot loader may use the -following hooks that, if set, are invoked by the kernel at the -appropriate time. The use of these hooks should probably be -considered an absolutely last resort! - -IMPORTANT: All the hooks are required to preserve %esp, %ebp, %esi and -%edi across invocation. - - realmode_swtch: - A 16-bit real mode far subroutine invoked immediately before - entering protected mode. The default routine disables NMI, so - your routine should probably do so, too. - - code32_start: - A 32-bit flat-mode routine *jumped* to immediately after the - transition to protected mode, but before the kernel is - uncompressed. No segments, except CS, are guaranteed to be - set up (current kernels do, but older ones do not); you should - set them up to BOOT_DS (0x18) yourself. - - After completing your hook, you should jump to the address - that was in this field before your boot loader overwrote it - (relocated, if appropriate.) - - -**** 32-bit BOOT PROTOCOL - -For machine with some new BIOS other than legacy BIOS, such as EFI, -LinuxBIOS, etc, and kexec, the 16-bit real mode setup code in kernel -based on legacy BIOS can not be used, so a 32-bit boot protocol needs -to be defined. - -In 32-bit boot protocol, the first step in loading a Linux kernel -should be to setup the boot parameters (struct boot_params, -traditionally known as "zero page").

I think that per-device dma_mapping_ops support would be also helpful for KVM people to support PCI passthrough but Andi thinks that this makes it difficult to support the PCI passthrough (see the above thread). So I CC'ed this to KVM camp. Comments are appreciated. A pointer to dma_mapping_ops to struct dev_archdata is added. If the pointer is non NULL, DMA operations in asm/dma-mapping.h use it. If it's NULL, the system-wide dma_ops pointer is used as before. If it's useful for KVM people, I plan to implement a mechanism to register a hook called when a new pci (or dma capable) device is created (it works with hot plugging). It enables IOMMUs to set up an appropriate dma_mapping_ops per device. The major obstacle is that dma_mapping_error doesn't take a pointer to the device unlike other DMA operations. So x86 can't have dma_mapping_ops per device. Note all the POWER IOMMUs use the same dma_mapping_error function so this is not a problem for POWER but x86 IOMMUs use different dma_mapping_error functions. The first patch adds the device argument to dma_mapping_error. The patch is trivial but large since it touches lots of drivers and dma-mapping.h in all the architecture. This patch: dma_mapping_error() doesn't take a pointer to the device unlike other DMA operations. So we can't have dma_mapping_ops per device. Note that POWER already has dma_mapping_ops per device but all the POWER IOMMUs use the same dma_mapping_error function. x86 IOMMUs use device argument.

useful for early logging Allows one to create and use a channel with no associated files. Files can be initialized later. This is useful in scenarios such as logging in early code, before VFS is up. Therefore, such channels can be created and used as soon as kmem_cache_init() completed. This is needed by kmemtrace to do tracing in early kernel code.

This filesystem module enables people to access files on these devices. This patch: OMFS is a proprietary filesystem created for the ReplayTV and also used by the Rio Karma. It uses hash tables with unordered, unbounded lists in each bucket for directories, extents for data blocks, 64-bit addressing for blocks, with up to 8K blocks (only 2K of a given block is ever used for metadata, so the FS still works with 4K pages).

Currently, even if you pass model=intel-mac-v3 as a module parameter to snd_hda_intel, the function patch_stac922x (patch_sigmatel.c) will still try to auto-detect the model type. This is a problem on my MacBook Pro 1st generation, which needs intel-mac-v3, but sometimes incorrectly reports 0x00000100 as subsystem id, which causes the switch in patch_stac922x to select intel-mac-v4. To fix this, I added a new model called intel-mac-auto, so in case no module parameter is passed, and an Intel Mac board is detected, the model will be automatically detected, while no detection will be done if the model is forced to intel-mac-v3. This problem has been around for quite a while, and I used to fix it by moving the case statement for 0x00000100 in patch_stac922x so that intel-mac-v3 is chosen. Another way to fix the problem would be to check if a module parameter was set directly in patch_stac922x, using something like this: if (spec->board_config == STAC_INTEL_MAC_V3 && !codec->bus->modelname) { But I think it is less elegant (if you prefer that way, I can prepare a patch).

Otherwise, the kernel may crash as - soon as you start any threads or processes due to VM collisions - in the kernel or user process space. - - - Details from Dan Malek on 10/29/1999: - - The user application virtual space consumes the first 2 Gbytes - (0x00000000 to 0x7FFFFFFF). The kernel virtual text starts at - 0xC0000000, with data following. There is a "protection hole" - between the end of kernel data and the start of the kernel - dynamically allocated space, but this space is still within - 0xCxxxxxxx. - - Obviously the kernel can't map any physical addresses 1:1 in - these ranges. - - - Details from Dan Malek on 5/19/2000: - - During the early kernel initialization, the kernel virtual - memory allocator is not operational. Prior to this KVM - initialization, we choose to map virtual to physical addresses - 1:1. That is, the kernel virtual address exactly matches the - physical address on the bus. These mappings are typically done - in arch/ppc/kernel/head.S, or arch/ppc/mm/init.c. Only - absolutely necessary mappings should be done at this time, for - example board control registers or a serial uart. Normal device - driver initialization should map resources later when necessary. - - Although platform dependent, and certainly the case for embedded - 8xx, traditionally memory is mapped at physical address zero, - and I/O devices above physical address 0x80000000. The lowest - and highest (above 0xf0000000) I/O addresses are traditionally - used for devices or registers we need to map during kernel - initialization and prior to KVM operation. For this reason, - and since it followed prior PowerPC platform examples, I chose - to map the embedded 8xx kernel to the 0xc0000000 virtual address. - This way, we can enable the MMU to map the kernel for proper - operation, and still map a few windows before the KVM is operational. - - On some systems, you could possibly run the kernel at the - 0x80000000 or any other virtual address. It just depends upon - mapping that must be done prior to KVM operational. You can never - map devices or kernel spaces that overlap with the user virtual - space. This is why default IMMR mapping used by most BDM tools - won't work. They put the IMMR at something like 0x10000000 or - 0x02000000 for example. You simply can't map these addresses early - in the kernel, and continue proper system operation. - - The embedded 8xx/82xx kernel is mature enough that all you should - need to do is map the IMMR someplace at or above 0xf0000000 and it - should boot far enough to get serial console messages and KGDB - connected on any platform. There are lots of other subtle memory - management design features that you simply don't need to worry - about. If you are changing functions related to MMU initialization, - you are likely breaking things that are known to work and are - heading down a path of disaster and frustration.

Constraints exist at three levels: + + Regulator Level: This is defined by the regulator hardware + operating parameters and is specified in the regulator + datasheet. i.e. + + - voltage output is in the range 800mV -> 3500mV. + - regulator current output limit is 20mA @ 5V but is + 10mA @ 10V. + + Power Domain Level: This is defined in software by kernel + level board initialisation code. It is used to constrain a + power domain to a particular power range. i.e. + + - Domain-1 voltage is 3300mV + - Domain-2 voltage is 1400mV -> 1600mV + - Domain-3 current limit is 0mA -> 20mA. + + Consumer Level: This is defined by consumer drivers + dynamically setting voltage or current limit levels. + + e.g. a consumer backlight driver asks for a current increase + from 5mA to 10mA to increase LCD illumination. This passes + to through the levels as follows :- + + Consumer: need to increase LCD brightness. Lookup and + request next current mA value in brightness table (the + consumer driver could be used on several different + personalities based upon the same reference device). + + Power Domain: is the new current limit within the domain + operating limits for this domain and system state (e.g. + battery power, USB power) + + Regulator Domains: is the new current limit within the + regulator operating parameters for input/ouput voltage. + + If the regulator request passes all the constraint tests + then the new regulator value is applied. + + +Design +====== + +The framework is designed and targeted at SoC based devices but may also be +relevant to non SoC devices and is split into the following four interfaces:- + + + 1. Consumer driver interface. + + This uses a similar API to the kernel clock interface in that consumer + drivers can get and put a regulator (like they can with clocks atm) and + get/set voltage, current limit, mode, enable and disable. This should + allow consumers complete control over their supply voltage and current + limit. This also compiles out if not in use so drivers can be reused in + systems with no regulator based power control. + + See Documentation/power/regulator/consumer.txt + + 2. Regulator driver interface. + + This allows regulator drivers to register their regulators and provide + operations to the core. It also has a notifier call chain for propagating + regulator events to clients. + + See Documentation/power/regulator/regulator.txt + + 3. Machine interface. + + This interface is for machine specific code and allows the creation of + voltage/current domains (with constraints) for each regulator. It can + provide regulator constraints that will prevent device damage through + overvoltage or over current caused by buggy client drivers. It also + allows the creation of a regulator tree whereby some regulators are + supplied by others (similar to a clock tree). + + See Documentation/power/regulator/machine.txt + + 4. Userspace ABI. + + The framework also exports a lot of useful voltage/current/opmode data to + userspace via sysfs. This could be used to help monitor device power + consumption and status. + + See Documentation/ABI/testing/regulator-sysfs.txt -- cgit v1.2.3 From 6392776d262fcd290616ff5e4246ee95b22c13f0 Mon Sep 17 00:00:00 2001 From: Liam Girdwood Date: Wed, 30 Apr 2008 17:19:02 +0100 Subject: regulator: documentation - consumer interface This adds documentation describing the consumer device interface.

Consumer Regulator Access (static & dynamic drivers) +======================================================= + +A consumer driver can get access to it's supply regulator by calling :- + +regulator = regulator_get(dev, "Vcc"); + +The consumer passes in it's struct device pointer and power supply ID. The core +then finds the correct regulator by consulting a machine specific lookup table. +If the lookup is successful then this call will return a pointer to the struct +regulator that supplies this consumer. + +To release the regulator the consumer driver should call :- + +regulator_put(regulator); + +Consumers can be supplied by more than one regulator e.g. codec consumer with +analog and digital supplies :- + +digital = regulator_get(dev, "Vcc"); /* digital core */ +analog = regulator_get(dev, "Avdd"); /* analog */ + +The regulator access functions regulator_get() and regulator_put() will +usually be called in your device drivers probe() and remove() respectively. + + +2. Regulator Output Enable & Disable (static & dynamic drivers) +==================================================================== + +A consumer can enable it's power supply by calling:- + +int regulator_enable(regulator); + +NOTE: The supply may already be enabled before regulator_enabled() is called. +This may happen if the consumer shares the regulator or the regulator has been +previously enabled by bootloader or kernel board initialization code. + +A consumer can determine if a regulator is enabled by calling :- + +int regulator_is_enabled(regulator); + +This will return > zero when the regulator is enabled. + + +A consumer can disable it's supply when no longer needed by calling :- + +int regulator_disable(regulator); + +NOTE: This may not disable the supply if it's shared with other consumers. The +regulator will only be disabled when the enabled reference count is zero. + +Finally, a regulator can be forcefully disabled in the case of an emergency :- + +int regulator_force_disable(regulator); + +NOTE: this will immediately and forcefully shutdown the regulator output. All +consumers will be powered off. + + +3. Regulator Voltage Control & Status (dynamic drivers) +====================================================== + +Some consumer drivers need to be able to dynamically change their supply +voltage to match system operating points. e.g. CPUfreq drivers can scale +voltage along with frequency to save power, SD drivers may need to select the +correct card voltage, etc. + +Consumers can control their supply voltage by calling :- + +int regulator_set_voltage(regulator, min_uV, max_uV); + +Where min_uV and max_uV are the minimum and maximum acceptable voltages in +microvolts. + +NOTE: this can be called when the regulator is enabled or disabled. If called +when enabled, then the voltage changes instantly, otherwise the voltage +configuration changes and the voltage is physically set when the regulator is +next enabled. + +The regulators configured voltage output can be found by calling :- + +int regulator_get_voltage(regulator); + +NOTE: get_voltage() will return the configured output voltage whether the +regulator is enabled or disabled and should NOT be used to determine regulator +output state. However this can be used in conjunction with is_enabled() to +determine the regulator physical output voltage. + + +4. Regulator Current Limit Control & Status (dynamic drivers) +=========================================================== + +Some consumer drivers need to be able to dynamically change their supply +current limit to match system operating points. e.g. LCD backlight driver can +change the current limit to vary the backlight brightness, USB drivers may want +to set the limit to 500mA when supplying power. + +Consumers can control their supply current limit by calling :- + +int regulator_set_current_limit(regulator, min_uV, max_uV); + +Where min_uA and max_uA are the minimum and maximum acceptable current limit in +microamps. + +NOTE: this can be called when the regulator is enabled or disabled. If called +when enabled, then the current limit changes instantly, otherwise the current +limit configuration changes and the current limit is physically set when the +regulator is next enabled. + +A regulators current limit can be found by calling :- + +int regulator_get_current_limit(regulator); + +NOTE: get_current_limit() will return the current limit whether the regulator +is enabled or disabled and should not be used to determine regulator current +load. + + +5. Regulator Operating Mode Control & Status (dynamic drivers) +============================================================= + +Some consumers can further save system power by changing the operating mode of +their supply regulator to be more efficient when the consumers operating state +changes. e.g. consumer driver is idle and subsequently draws less current + +Regulator operating mode can be changed indirectly or directly. + +Indirect operating mode control. +-------------------------------- +Consumer drivers can request a change in their supply regulator operating mode +by calling :- + +int regulator_set_optimum_mode(struct regulator *regulator, int load_uA); + +This will cause the core to recalculate the total load on the regulator (based +on all it's consumers) and change operating mode (if necessary and permitted) +to best match the current operating load. + +The load_uA value can be determined from the consumers datasheet. e.g.most +datasheets have tables showing the max current consumed in certain situations. + +Most consumers will use indirect operating mode control since they have no +knowledge of the regulator or whether the regulator is shared with other +consumers. + +Direct operating mode control. +------------------------------ +Bespoke or tightly coupled drivers may want to directly control regulator +operating mode depending on their operating point. This can be achieved by +calling :- + +int regulator_set_mode(struct regulator *regulator, unsigned int mode); +unsigned int regulator_get_mode(struct regulator *regulator); + +Direct mode will only be used by consumers that *know* about the regulator and +are not sharing the regulator with other consumers. + + +6. Regulator Events +=================== +Regulators can notify consumers of external events. Events could be received by +consumers under regulator stress or failure conditions. + +Consumers can register interest in regulator events by calling :- + +int regulator_register_notifier(struct regulator *regulator, + struct notifier_block *nb); + +Consumers can uregister interest by calling :- + +int regulator_unregister_notifier(struct regulator *regulator, + struct notifier_block *nb); + +Regulators use the kernel notifier framework to send event to thier interested +consumers. -- cgit v1.2.3 From e8695ebe5568921c41c269f4434e17590735865c Mon Sep 17 00:00:00 2001 From: Liam Girdwood Date: Wed, 30 Apr 2008 17:20:11 +0100 Subject: regulator: documentation - regulator driver This adds documentation describing the regulator driver interface.

When this option is on, a breakpoint cannot be written into any readonly memory page. When an external debugger requests a breakpoint to get set, the kgdb_validate_break_address() was only checking to see if the address to place the breakpoint was readable and lacked a write check. This patch changes the validate routine to try reading (via the breakpoint set request) and also to try immediately writing the break point. If either fails, an error is correctly returned and the debugger behaves correctly. Then an end user can make the descision to use hardware breakpoints. Also update the documentation to reflect that using CONFIG_DEBUG_RODATA will inhibit the use of software breakpoints.

The only users who have reported that they were still using this parameter, needed it to switch the chip from automatic fan speed control back to manual mode.
