tools headers: Sync x86 cpufeatures.h with the kernel sources

2018-05-07T18:23:45+00:00

The 912413057395 ("x86/cpufeatures: Enumerate cldemote instruction")
doesn't requires changes in the tools, just copy it to silence this
warning:

  Warning: Kernel ABI header at 'tools/arch/x86/include/asm/cpufeatures.h' differs from latest version at 'arch/x86/include/asm/cpufeatures.h'

tools/headers: Synchronize kernel ABI headers, v4.17-rc1

2018-04-17T12:47:39+00:00

Sync the following tooling headers with the latest kernel version:

  tools/arch/arm/include/uapi/asm/kvm.h
    - New ABI: KVM_REG_ARM_*

  tools/arch/x86/include/asm/required-features.h
    - Removal of NEED_LA57 dependency

  tools/arch/x86/include/uapi/asm/kvm.h
    - New KVM ABI: KVM_SYNC_X86_*

  tools/include/uapi/asm-generic/mman-common.h
    - New ABI: MAP_FIXED_NOREPLACE flag

  tools/include/uapi/linux/bpf.h
    - New ABI: BPF_F_SEQ_NUMBER functions

  tools/include/uapi/linux/if_link.h
    - New ABI: IFLA tun and rmnet support

  tools/include/uapi/linux/kvm.h
    - New ABI: hyperv eventfd and CONN_ID_MASK support plus header cleanups

  tools/include/uapi/sound/asound.h
    - New ABI: SNDRV_PCM_FORMAT_FIRST PCM format specifier

  tools/perf/arch/x86/entry/syscalls/syscall_64.tbl
    - The x86 system call table description changed due to the ptregs changes and the renames, in:

	d5a00528b58c: syscalls/core, syscalls/x86: Rename struct pt_regs-based sys_*() to __x64_sys_*()
	5ac9efa3c50d: syscalls/core, syscalls/x86: Clean up compat syscall stub naming convention
	ebeb8c82ffaf: syscalls/x86: Use 'struct pt_regs' based syscall calling for IA32_EMULATION and x32

Also fix the x86 syscall table warning:

  -Warning: Kernel ABI header at 'tools/arch/x86/entry/syscalls/syscall_64.tbl' differs from latest version at 'arch/x86/entry/syscalls/syscall_64.tbl'
  +Warning: Kernel ABI header at 'tools/perf/arch/x86/entry/syscalls/syscall_64.tbl' differs from latest version at 'arch/x86/entry/syscalls/syscall_64.tbl'

None of these changes impact existing tooling code, so we only have to copy the kernel version.

tools headers: Synchronize x86's cpufeatures.h

2018-04-02T10:57:37+00:00

Due to these commits:

  1da961d72ab0 ("x86/cpufeatures: Add Intel Total Memory Encryption cpufeature")
  7958b2246fad ("x86/cpufeatures: Add Intel PCONFIG cpufeature")

To silence this perf build warning:

  Warning: Kernel ABI header at 'tools/arch/x86/include/asm/cpufeatures.h' differs from latest version at 'arch/x86/include/asm/cpufeatures.h'

Nothing in those csets requires changes in tools/perf/, so just
sync it to silence the build.

tools headers: Sync x86's cpufeatures.h

2018-03-05T15:07:52+00:00

The changes in dd84441a7971 ("x86/speculation: Use IBRS if available
before calling into firmware") don't need any kind of special treatment
in the current tools/perf/ codebase, so just update the copy to get rid
of the perf build warning:

tools/headers: Synchronize kernel ABI headers, v4.16-rc1

2018-02-15T13:01:46+00:00

Sync the following tooling headers with the latest kernel version:

  tools/arch/powerpc/include/uapi/asm/kvm.h
  tools/arch/x86/include/asm/cpufeatures.h
  tools/include/uapi/drm/i915_drm.h
  tools/include/uapi/linux/if_link.h
  tools/include/uapi/linux/kvm.h

All the changes are new ABI additions which don't impact their use
in existing tooling.

tools headers: Synchoronize x86 features UAPI headers

2018-02-02T20:22:12+00:00

Sync tools/arch/x86/include/asm/{cpu,disabled-,required-}features.h with
the changes in:

  20ffa1caecca ("x86/speculation: Add basic IBPB (Indirect Branch Prediction Barrier) support")

tools include arch: Grab a copy of errno.h for arch's supported by perf

2018-01-23T12:51:37+00:00

For each arch in tools/perf/arch, grab a copy of errno.h.

This is a pre-req to generate an architecture specific mapping of errno
numbers to their names.  This errno mapping can be used by perf trace to
support cross-architecture trace reports and to get rid of the
audit-libs dependency.

tools headers: Synchronize kernel <-> tooling headers

2018-01-10T15:46:54+00:00

Two kernel headers got modified recently due to meltdown/spectre, in:

  a89f040fa34e ("x86/cpufeatures: Add X86_BUG_CPU_INSECURE")

which are used by tooling as well:

  arch/x86/include/asm/cpufeatures.h
  arch/x86/include/asm/disabled-features.h

None of those changes have an effect on tooling, so do a plain copy.

Two x86 headers got modified in this merge window:

 arch/x86/include/asm/cpufeatures.h
