commit ecad3312111798d84dac1ce6a853e0ac9de8d505
category: bugfix

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=ecad3312111798d84dac1ce6a853e0ac9de8d505

--------------------------------

New pahole (version 1.24) generates by default new BTF_KIND_ENUM64 BTF tag,
which is not supported by stable kernel.

As a result the kernel with CONFIG_DEBUG_INFO_BTF option will fail to
compile with following error:

  BTFIDS  vmlinux
FAILED: load BTF from vmlinux: Invalid argument

New pahole provides --skip_encoding_btf_enum64 option to skip BTF_KIND_ENUM64
generation and produce BTF supported by stable kernel.

Adding this option to scripts/pahole-flags.sh.

This change does not have equivalent commit in linus tree, because linus tree
has support for BTF_KIND_ENUM64 tag, so it does not need to be disabled.

--------------------------------

commit a0b8200d upstream.

[small context changes due to missing floats support in 5.10]

Commit "mm/page_alloc: convert per-cpu list protection to local_lock" will
introduce a zero-sized per-CPU variable, which causes pahole to generate
invalid BTF.  Only pahole versions 1.18 through 1.21 are impacted, as
before 1.18 pahole doesn't know anything about per-CPU variables, and 1.22
contains the proper fix for the issue.

Luckily, pahole 1.18 got --skip_encoding_btf_vars option disabling BTF
generation for per-CPU variables in anticipation of some unanticipated
problems.  So use this escape hatch to disable per-CPU var BTF info on
those problematic pahole versions.  Users relying on availability of
per-CPU var BTFs would need to upgrade to pahole 1.22+, but everyone won't
notice any regressions.

--------------------------------

commit ff2e6efd upstream.

[backported for dependency, skipped Makefile.modfinal change,
because module BTF is not supported in 5.10]

The ccache tool can be used to speed up cross-compilation, by calling the
compiler and binutils through ccache. For example, following should work:

    $ export ARCH=arm64 CROSS_COMPILE="ccache aarch64-linux-gnu-"

    $ make M=drivers/gpu/drm/rockchip/

but pahole fails to extract the BTF info from DWARF, breaking the build:

      CC [M]  drivers/gpu/drm/rockchip//rockchipdrm.mod.o
      LD [M]  drivers/gpu/drm/rockchip//rockchipdrm.ko
      BTF [M] drivers/gpu/drm/rockchip//rockchipdrm.ko
    aarch64-linux-gnu-objcopy: invalid option -- 'J'
    Usage: aarch64-linux-gnu-objcopy [option(s)] in-file [out-file]
     Copies a binary file, possibly transforming it in the process
    ...
    make[1]: *** [scripts/Makefile.modpost:156: __modpost] Error 2
    make: *** [Makefile:1866: modules] Error 2

this fails because OBJCOPY is set to "ccache aarch64-linux-gnu-copy" and
later pahole is executed with the following command line:

    LLVM_OBJCOPY=$(OBJCOPY) $(PAHOLE) -J --btf_base vmlinux $@

which gets expanded to:

    LLVM_OBJCOPY=ccache aarch64-linux-gnu-objcopy pahole -J ...

instead of:

    LLVM_OBJCOPY="ccache aarch64-linux-gnu-objcopy" pahole -J ...

[backported for dependency only extra_paholeopt variable setup and

generate the information about the floating-point types [1].

Adjust link-vmlinux.sh to pass this flag to pahole in case it's
supported, which is determined using a simple version check.

intel_idle: add Emerald Rapids Xeon support
commit 74528edf upstream.
Emerald Rapids (EMR) is the next Intel Xeon processor after Sapphire
Rapids (SPR).

EMR C-states are the same as SPR C-states, and we expect that EMR
C-state characteristics (latency and target residency) will be the
same as in SPR. Therefore, add EMR support by using SPR C-states table.

[Description]​
SPR: EDAC driver enhance for driver decode and 2LM

Current i10nm_edac only supports firmware decoder (ACPI DSM methods) for Sapphire Rapids. So add the driver decoder(decoding DDR memory errors via extracting error information from the IMC MC error codes) for Sapphire Rapids for better decoding performance.
Enhance the SPR HBM EDAC driver to decode errors from the 1st level memory (the fast "near" memory as cache) of the 2-level memory system.

It will be valuable to avoid SMI triggered to call firware decoder, especially when CE (Correctable Error) triggered frequently on DDR memory.

6e8746cb EDAC/skx_common: Enable EDAC support for the "near" memory.
221aa03f EDAC/i10nm: Add driver decoder for Sapphire Rapids server.

(v6.2-rc4) 69ced416 perf/x86/msr: Add Emerald Rapids

The four 6.2 patches above use a macro "INTEL_FAM6_EMERALDRAPIDS_X", which is introduced by:
(v6.1-rc1) 7beade0d x86/cpu: Add several Intel server CPU model numbers
This patch is already included in another PR:
https://gitee.com/openeuler/kernel/pulls/469

Note: this PR for PMU must be merged AFTER PR-469, otherwise there will be kernel compiling error complaining for missing definition of macro "INTEL_FAM6_EMERALDRAPIDS_X".

Test:
1. platform dependent core PMU event works with perf, like "L1-dcache-loads".
2. platform dependent uncore PMU event works with perf, like "uncore_imc_0/event=0x1/".
3. offcore event works with perf.
3. PEBS works with perf.
4. topdown works with perf.
With this PR(along with the patch from PR469) applied to kernel OLK-5.10, all tests above PASS on EMR.

Running Average Power Limit (RAPL) is an interface for reporting accumulated energy consumption of various system-on-chip (SoC) power domains. The RAPL energy reporting feature has been available for many generations on Intel SoC products.

To enable perf collecting RAPL events on future Intel Xeon platform Emerald Rapids, below upstream commit is needed:
(v6.2-rc3)  57512b57 perf/x86/rapl: Add support for Intel Emerald Rapids

This patch uses a macro "INTEL_FAM6_EMERALDRAPIDS_X" which is introduced with upstream commit:
(v6.1-rc1) 7beade0d x86/cpu: Add several Intel server CPU model numbers
which has been backported to OLK-5.10 earlier with this PR(under review, not merged yet):
https://gitee.com/openeuler/kernel/pulls/469
So here setting PR-469 as a dependency of this RAPL backport.

Note: this PR must be merged AFTER PR-469, otherwise there will be kernel compiling error complaining for missing definition of macro "INTEL_FAM6_EMERALDRAPIDS_X".

Intel-Kernel Issue:
https://gitee.com/openeuler/intel-kernel/issues/I6YGL6

Test:
With the patches in this PR included, running command below will list energy-psys events on EMR:

sysfs node. The user space can get the device isolated state by 'isolate'
sysfs node. If the number of device errors exceeds the configured error
threshold, the device will be isolated. It means the uacce device is
unavailable.

category: feature
bugzilla: https://gitee/com/openeuler/kernel/issues/16VW8E
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=00bef64ac3c95ab0f73b5d352743bf2bd6f5fc99

-------------------------------------------------------------------

While reviewing dependencies in some Kconfig files, I noticed the redundant
dependency "depends on PCI && PCI_MSI". The config PCI_MSI has always,
since its introduction, been dependent on the config PCI. So, it is
sufficient to just depend on PCI_MSI, and know that the dependency on PCI
is implicitly implied.

Reduce the dependencies of configs CRYPTO_DEV_HISI_SEC2,
CRYPTO_DEV_HISI_QM, CRYPTO_DEV_HISI_ZIP and CRYPTO_DEV_HISI_HPRE.

No functional change and effective change of Kconfig dependendencies.

category: bugfix
bugzilla: https://gitee/com/openeuler/kernel/issues/16VW8E
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=2ae6feb1a1f6678fe11864f1b6920ed10b09ad6a

-------------------------------------------------------------------

Commit d2825fa9 ("crypto: sm3,sm4 - move into crypto directory") moves
the SM3 and SM4 stand-alone library and the algorithm implementation for
the Crypto API into the same directory, and the corresponding relationship
of Kconfig is modified, CONFIG_CRYPTO_SM3/4 corresponds to the stand-alone
library of SM3/4, and CONFIG_CRYPTO_SM3/4_GENERIC corresponds to the
algorithm implementation for the Crypto API. Therefore, it is necessary
for this module to depend on the correct algorithm.

In function 'hisi_qm_resume', if the device fails to be started,
directly returning error code will cause the device to be unavailable.
However, the failure may be caused by device error, which will be
reported to the driver, and driver can reset and restart device.
Therefore, check device status instead of returning error code
directly. Returns 0 if device error has occurred, otherwise returns
error code.

Here is the typical case that priority inversion will caused occasionally
by SMT expelling: Assuming that there are two SMT cores-cA and cB,
online tasks are running on cA while offline tasks on cB. With SMT
expelling, online task will drives off offline tasks to occupy all SMT
cores exclusively, which, in turn, will starve the offline task to release
the related resources other tasks with higher priority need.

Hence, this patch will introduce another mechanism to alleviate this
situation. For all offline tasks, one metric of profiling the maximum task
expelling duration is set up and the default value is 5 seconds, if
such offline task exsits, all offline tasks will be allowed to run into
one small sleep(msleep) loop in kernel before they goes into
usermode; and further, if the two SMT cores(such as cA and cB) are
idle or don't get any online tasks to run, for these offline tasks, they
will continue to run in usermode for the next schedule.

This PR is to enable support for Intel new fast rep string operation performance enhancement.

Starting with Golden Cove microarchitecture (SPR and Alderlake), Intel CPU support some rep string
operation performance enhancement, which include the following features:
- fast zero-length MOVSB
- fast short STOSB
- fast short CMPSB, SCASB

More information see section 3.8 of "Intel® 64 and IA-32 Architectures Optimization Reference Manual".

## Intel-Kernel Issue
#I6YPV0

## Test
Launch VM and run cpuid, we can see following cpu features are true:
```
fast zero-length MOVSB                   = true
fast short STOSB                         = true
fast short CMPSB, SCASB                  = true
```
Without this patchset, these features are false.

## Known Issue
N/A

## Default Config Change
N/A
