Zong Li <zong.li@sifive.com> says:
Since composable cache may be L3 cache if private L2 cache exists, we
should use its original name "composable cache" to prevent confusion.
This patchset contains the modification which is related to ccache, such
as DT binding and EDAC driver.
* b4-shazam-merge:
riscv: Add cache information in AUX vector
soc: sifive: ccache: define the macro for the register shifts
soc: sifive: ccache: use pr_fmt() to remove CCACHE: prefixes

There are no standard CSR registers to provide cache information, the
way for RISC-V is to get this information from DT. sysconf syscall
could use them to get information of cache through AUX vector.
The result of 'getconf -a|grep -i cache' as follows:
LEVEL1_ICACHE_SIZE 32768
LEVEL1_ICACHE_ASSOC 2
LEVEL1_ICACHE_LINESIZE 64
LEVEL1_DCACHE_SIZE 32768

Wrapping things in #ifdefs makes the code harder to read
while we also have IS_ENABLED() macros to do this in regular code
and the extension detection is not _that_ runtime critical.
So define a stub for riscv_noncoherent_supported() in the
non-CONFIG_RISCV_DMA_NONCOHERENT case and move the code to
us IS_ENABLED.

I don't think we can actually die() without a regs pointer, but the
compiler was warning about a NULL check after a dereference. It seems
prudent to just avoid the possibly-NULL dereference, given that when
die()ing the system is already toast so who knows how we got there.

Microchip RISC-V devicetrees for v6.1
Fixups, reference design changes and new boards:
- The addition of QSPI support for mpfs had a corresponding change to
the devicetree node.
- The v2022.{09,10} reference designs brought with them several memory
map changes which are not backwards compatible. The old devicetrees
from the v2022.08 and earlier releases still work with current
kernels.
- Two new devicetrees for a first-party development kit and for the
Aries Embedded M100FPSEVP kit.
- Corresponding dt-bindings changes for the above.

When CONFIG_CMDLINE_FORCE is enabled, cmdline provided by
CONFIG_CMDLINE are always used. This allows CONFIG_CMDLINE to be
used regardless of the result of device tree scanning.
This especially fixes the case where a device tree without the
chosen node is supplied to the kernel. In such cases,
early_init_dt_scan would return true. But inside
early_init_dt_scan_chosen, the cmdline won't be updated as there
is no chosen node in the device tree. As a result, CONFIG_CMDLINE
is not copied into boot_command_line even if CONFIG_CMDLINE_FORCE
is enabled. This commit allows properly update boot_command_line
in this situation.

- Tracepoint cleanups/fixes for nested VM-Enter and emulated MSR
accesses
- Drop eVMCS controls filtering for KVM on Hyper-V, all known
versions of Hyper-V now support eVMCS fields associated with
features that are enumerated to the guest
- Use KVM's sanitized VMCS config as the basis for the values of
nested VMX capabilities MSRs
- A myriad event/exception fixes and cleanups. Most notably, pending
exceptions morph into VM-Exits earlier, as soon as the exception is
queued, instead of waiting until the next vmentry. This fixed a
longstanding issue where the exceptions would incorrecly become
double-faults instead of triggering a vmexit; the common case of
page-fault vmexits had a special workaround, but now it's fixed for
good

git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi
Pull EFI updates from Ard Biesheuvel:
"A bit more going on than usual in the EFI subsystem. The main driver
for this has been the introduction of the LoonArch architecture last
cycle, which inspired some cleanup and refactoring of the EFI code.
Another driver for EFI changes this cycle and in the future is
confidential compute.
The LoongArch architecture does not use either struct bootparams or DT
natively [yet], and so passing information between the EFI stub and
the core kernel using either of those is undesirable. And in general,
overloading DT has been a source of issues on arm64, so using DT for
this on new architectures is a to avoid for the time being (even if we
might converge on something DT based for non-x86 architectures in the
future). For this reason, in addition to the patch that enables EFI
boot for LoongArch, there are a number of refactoring patches applied
on top of which separate the DT bits from the generic EFI stub bits.
These changes are on a separate topich branch that has been shared
with the LoongArch maintainers, who will include it in their pull
request as well. This is not ideal, but the best way to manage the
conflicts without stalling LoongArch for another cycle.
Another development inspired by LoongArch is the newly added support
for EFI based decompressors. Instead of adding yet another
arch-specific incarnation of this pattern for LoongArch, we are
introducing an EFI app based on the existing EFI libstub
infrastructure that encapulates the decompression code we use on other
architectures, but in a way that is fully generic. This has been
developed and tested in collaboration with distro and systemd folks,
who are eager to start using this for systemd-boot and also for arm64
secure boot on Fedora. Note that the EFI zimage files this introduces
can also be decompressed by non-EFI bootloaders if needed, as the
image header describes the location of the payload inside the image,
and the type of compression that was used. (Note that Fedora's arm64
GRUB is buggy [0] so you'll need a recent version or switch to
systemd-boot in order to use this.)
Finally, we are adding TPM measurement of the kernel command line
provided by EFI. There is an oversight in the TCG spec which results
in a blind spot for command line arguments passed to loaded images,
which means that either the loader or the stub needs to take the
measurement. Given the combinatorial explosion I am anticipating when
it comes to firmware/bootloader stacks and firmware based attestation
protocols (SEV-SNP, TDX, DICE, DRTM), it is good to set a baseline now
when it comes to EFI measured boot, which is that the kernel measures
the initrd and command line. Intermediate loaders can measure
additional assets if needed, but with the baseline in place, we can
deploy measured boot in a meaningful way even if you boot into Linux
straight from the EFI firmware.
Summary:
- implement EFI boot support for LoongArch
- implement generic EFI compressed boot support for arm64, RISC-V and
LoongArch, none of which implement a decompressor today
- measure the kernel command line into the TPM if measured boot is in
effect
- refactor the EFI stub code in order to isolate DT dependencies for
architectures other than x86
- avoid calling SetVirtualAddressMap() on arm64 if the configured
size of the VA space guarantees that doing so is unnecessary
- move some ARM specific code out of the generic EFI source files
- unmap kernel code from the x86 mixed mode 1:1 page tables"

Pull clk updates from Stephen Boyd:
"We have some late breaking reports that a patch series to rework clk
rate range support broke boot on some devices, so I've left that
branch out of this. Hopefully we can get to that next week, or punt on
it and let it bake another cycle. That means we don't really have any
changes to the core framework this time around besides a few typo
fixes. Instead this is all clk driver updates and fixes.
The usual suspects are here (again), with Qualcomm dominating the
diffstat. We look to have gained support for quite a few new Qualcomm
SoCs and Dmitry worked on updating many of the existing Qualcomm
drivers to use clk_parent_data. After that we have MediaTek drivers
getting some much needed updates, in particular to support GPU DVFS.
There are also quite a few Samsung clk driver patches, but that's
mostly because there was a maintainer change and so last release we
missed some of those patches.
Overall things look normal, but I'm slowly reviewing core framework
code nowadays and that shows given the rate range patches had to be
yanked last minute. Let's hope this situation changes soon.

- Support for Renesas VersaClock7 clock generator family
- Add Spreadtrum UMS512 SoC clk support
- New clock drivers for MediaTek Helio X10 MT6795

I have a Sipeed Lichee RV dock board which only has 512MB DDR, so
memory optimizations such as swap on zram are helpful. As is seen
in commit d0637c505f8a ("arm64: enable THP_SWAP for arm64") and
commit bd4c82c22c367e ("mm, THP, swap: delay splitting THP after
swapped out"), THP_SWAP can improve the swap throughput significantly.
Enable THP_SWAP for RV64, testing the micro-benchmark which is
introduced by commit d0637c505f8a ("arm64: enable THP_SWAP for arm64")
shows below numbers on the Lichee RV dock board:
swp out bandwidth w/o patch: 66908 bytes/ms (mean of 10 tests)
swp out bandwidth w/ patch: 322638 bytes/ms (mean of 10 tests)
Improved by 382%!

Pull ARM SoC updates from Arnd Bergmann:
"The main changes this time are for the organization of the Kconfig
files, introducing per-vendor top-level options on arm64 to match
those on arm32, and making the platform selection on arm32 more
uniform, in particular for the remaining StrongARM platforms that
still have a couple of special cases compared to the more recent ones.
I also did a cleanup of the old Footbridge platform, which was the
last holdout for the phys_to_dma()/dma_to_phys() interface that is now
completely gone from arm32, completing work started by Christoph
Hellwig"

Pull ARM devicetree updates from Arnd Bergmann:
"Most of the changes fall into one of three categories: adding support
for additional devices on existing machines, cleaning up issues found
by the ongoing conversion to machine-readable bindings, and addressing
minor mistakes in the existing DT data.
Across SoC vendors, Qualcomm and Freescale stick out as getting the
most updates, which corresponds to their dominance in the mobile phone
and embedded industrial markets, respectively.
There are 636 non-merge changeset in this branch, which is a little
lower than most times, but more importantly we only add 36 machine
files, which is about half of what we had the past few releases.
Eight new SoCs are added, but all of them are variations of already
supported SoC families, and most of them come with one reference board
design from the SoC vendor:
- Mediatek MT8186 is a Chromebook/Tablet type SoC, similar to the
MT65xx series of phone SoCs, with two Cortex-A76 and six Cortex-A55
cores.
- TI AM62A is another member of the K3 family with Cortex-A53 cores,
this one is targetted at Video/Vision processing for industrial and
automotive applications.
- NXP i.MX8DXL is another chip for this market in the ever-growing
i.MX8 family, this one again with two Cortex-A35 cores.
- Renesas R-Car H3Ne-1.7G (R8A779MB) and R-Car V3H2 (R8A77980A) are
minor updates of R8A77951 and R8A77980, respectively.
- Qualcomm IPQ8064-v2.0, IPQ8062 and IPQ8065 are all variants of the
IPQ8064 chip, with minimally different features.
The AMD Pensando Elba and Apple M1 Ultra SoC support was getting close
this time, but in the end did not make the cut.
The new machines based on existing SoC support are fairly uneventful:
- Sony Xperia 1 IV is a fairly recent phone based on Qualcomm
Snapdragon 8 Gen 1.
- Three Samsung phones based on Snapdragon 410: Galaxy E5, E7 and
Grand Max. These are added for both 32-bit and 64-bit kernels, as
they originally shipped running 32-bit code.
- Two new servers using AST2600 BMCs: AMD DaytonaX and Ampere Mt.
Mitchell
- Three new machines based on Rockchips RK3399 and RK3566: Anberic
RG353P and RG503, Pine64 Pinephone Pro, Open AI Lab
- Multiple NXP i.MX6/i.MX8 based boards: Kontron SL/BL i.MX8MM OSM-S,
i.MX8MM Gateworks GW7904, MSC SM2S-IMX8PLUS SoM and carrier board
- Two development boards in the Microchip AT91 family: SAMA5D3-EDS
and lan966x-pcb8290.
- Minor variants of existing boards using Amlogic, Broadcom, Marvell,
Rockchips, Freescale Layerscape and Socionext Uniphier SoCs"

When compat mode isn't supported(I believe this is the most case now),
kernel will emit somthing as:
[ 0.050407] riscv: ELF compat mode failed
This msg may make users think there's something wrong with the kernel
itself, replace "failed" with "unsupported" to make it clear. In fact
this is the real compat_mode_supported meaning. After the patch, the
msg would be:
[ 0.050407] riscv: ELF compat mode unsupported

Similar to the issue resolved by commit 0072dc1b53c3 ("arm64: avoid
BUILD_BUG_ON() in alternative-macros"), there is a circular include
dependency through <linux/bits.h> when CONFIG_LTO is enabled due to
<asm/rwonce.h> appearing in the include chain before the contents of
<asm/alternative-macros.h>, which results in ALTERNATIVE() not getting
expanded properly because it has not been defined yet.
Avoid this issue by including <vdso/bits.h>, which includes the
definition of the BIT() macro, instead of <linux/bits.h>, as BIT() is the
only macro from bits.h that is relevant to this header.

Pull networking updates from Jakub Kicinski:
"Core:
- Introduce and use a single page frag cache for allocating small skb
heads, clawing back the 10-20% performance regression in UDP flood
test from previous fixes.
- Run packets which already went thru HW coalescing thru SW GRO. This
significantly improves TCP segment coalescing and simplifies
deployments as different workloads benefit from HW or SW GRO.
- Shrink the size of the base zero-copy send structure.
- Move TCP init under a new slow / sleepable version of DO_ONCE().
BPF:
- Add BPF-specific, any-context-safe memory allocator.
- Add helpers/kfuncs for PKCS#7 signature verification from BPF
programs.
- Define a new map type and related helpers for user space -> kernel
communication over a ring buffer (BPF_MAP_TYPE_USER_RINGBUF).
- Allow targeting BPF iterators to loop through resources of one
task/thread.
- Add ability to call selected destructive functions. Expose
crash_kexec() to allow BPF to trigger a kernel dump. Use
CAP_SYS_BOOT check on the loading process to judge permissions.
- Enable BPF to collect custom hierarchical cgroup stats efficiently
by integrating with the rstat framework.
- Support struct arguments for trampoline based programs. Only
structs with size <= 16B and x86 are supported.
- Invoke cgroup/connect{4,6} programs for unprivileged ICMP ping
sockets (instead of just TCP and UDP sockets).
- Add a helper for accessing CLOCK_TAI for time sensitive network
related programs.
- Support accessing network tunnel metadata's flags.
- Make TCP SYN ACK RTO tunable by BPF programs with TCP Fast Open.
- Add support for writing to Netfilter's nf_conn:mark.
Protocols:
- WiFi: more Extremely High Throughput (EHT) and Multi-Link Operation
(MLO) work (802.11be, WiFi 7).
- vsock: improve support for SO_RCVLOWAT.
- SMC: support SO_REUSEPORT.
- Netlink: define and document how to use netlink in a "modern" way.
Support reporting missing attributes via extended ACK.
- IPSec: support collect metadata mode for xfrm interfaces.
- TCPv6: send consistent autoflowlabel in SYN_RECV state and RST
packets.
- TCP: introduce optional per-netns connection hash table to allow
better isolation between namespaces (opt-in, at the cost of memory
and cache pressure).
- MPTCP: support TCP_FASTOPEN_CONNECT.
- Add NEXT-C-SID support in Segment Routing (SRv6) End behavior.
- Adjust IP_UNICAST_IF sockopt behavior for connected UDP sockets.
- Open vSwitch:
- Allow specifying ifindex of new interfaces.
- Allow conntrack and metering in non-initial user namespace.
- TLS: support the Korean ARIA-GCM crypto algorithm.
- Remove DECnet support.
Driver API:
- Allow selecting the conduit interface used by each port in DSA
switches, at runtime.
- Ethernet Power Sourcing Equipment and Power Device support.
- Add tc-taprio support for queueMaxSDU parameter, i.e. setting per
traffic class max frame size for time-based packet schedules.
- Support PHY rate matching - adapting between differing host-side
and link-side speeds.
- Introduce QUSGMII PHY mode and 1000BASE-KX interface mode.
- Validate OF (device tree) nodes for DSA shared ports; make
phylink-related properties mandatory on DSA and CPU ports.
Enforcing more uniformity should allow transitioning to phylink.
- Require that flash component name used during update matches one of
the components for which version is reported by info_get().
- Remove "weight" argument from driver-facing NAPI API as much as
possible. It's one of those magic knobs which seemed like a good
idea at the time but is too indirect to use in practice.
- Support offload of TLS connections with 256 bit keys.

Currently, the range and default value of NR_CPUS is too restrictive
for high-end RISC-V systems with large number of HARTs. The latest
QEMU virt machine supports upto 512 CPUs so the current NR_CPUS is
restrictive for QEMU as well. Other major architectures (such as
ARM64, x86_64, MIPS, etc) have a much higher range and default
value of NR_CPUS.
This patch increases NR_CPUS range to 2-512 and default value to
XLEN (i.e. 32 for RV32 and 64 for RV64).
