tools headers: Sync x86 kvm and cpufeature headers with the kernel

2024-12-04T22:34:49+00:00

To pick up the changes in this cset:

  dcb988cdac85bad1 ("KVM: x86: Quirk initialization of feature MSRs to KVM's max configuration")

This addresses these perf build warnings:

  Warning: Kernel ABI header differences:

Merge tag 'x86_cpu_for_v6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

2024-11-19T20:27:19+00:00

Pull x86 cpuid updates from Borislav Petkov:

 - Add a feature flag which denotes AMD CPUs supporting workload
   classification with the purpose of using such hints when making
   scheduling decisions

 - Determine the boost enumerator for each AMD core based on its type:
   efficiency or performance, in the cppc driver

 - Add the type of a CPU to the topology CPU descriptor with the goal of
   supporting and making decisions based on the type of the respective
   core

 - Add a feature flag to denote AMD cores which have heterogeneous
   topology and enable SD_ASYM_PACKING for those

 - Check microcode revisions before disabling PCID on Intel

 - Cleanups and fixlets

perf cap: Add __NR_capget to arch/x86 unistd

2024-10-28T16:04:52+00:00

As there are duplicated kernel headers in tools/include libc can pick
up the wrong definitions. This was causing the wrong system call for
capget in perf.

x86/cpufeatures: Rename X86_FEATURE_FAST_CPPC to have AMD prefix

This feature is an AMD unique feature of some processors, so put
AMD into the name.

tools arch x86: Sync the msr-index.h copy with the kernel sources

2024-10-24T13:27:59+00:00

To pick up the changes from these csets:

  dc1e67f70f6d4e33 ("KVM VMX: Move MSR_IA32_VMX_MISC bit defines to asm/vmx.h")
  d7bfc9ffd58037ff ("KVM: VMX: Move MSR_IA32_VMX_BASIC bit defines to asm/vmx.h")

  e7e80b66fb242a63 ("x86/cpu: KVM: Add common defines for architectural memory types (PAT, MTRRs, etc.)")

That cause no changes to tooling:

  $ tools/perf/trace/beauty/tracepoints/x86_msr.sh > before
  $ cp arch/x86/include/asm/msr-index.h tools/arch/x86/include/asm/msr-index.h
  $ tools/perf/trace/beauty/tracepoints/x86_msr.sh > after
  $ diff -u before after
  $

To see how this works take a look at this previous update:

  https://git.kernel.org/torvalds/c/174372668933ede5

  174372668933ede5 ("tools arch x86: Sync the msr-index.h copy with the kernel sources to pick IA32_MKTME_KEYID_PARTITIONING")

Just silences this perf build warning:

That don't change functionality in tools/perf, as no new ioctl is added
for the 'perf trace' scripts to harvest.
