tools headers powerpc: Remove unistd.h

2019-01-10T13:42:08+00:00

We use syscall.tbl to generate system call table on powerpc.

The unistd.h copy is no longer required now. Remove it.

powerpc/perf: Update perf_regs structure to include SIER

2018-12-20T09:53:11+00:00

On each sample, Sample Instruction Event Register (SIER) content
is saved in pt_regs. SIER does not have a entry as-is in the pt_regs
but instead, SIER content is saved in the "dar" register of pt_regs.

Patch adds another entry to the perf_regs structure to include the "SIER"
printing which internally maps to the "dar" of pt_regs.

It also check for the SIER availability in the platform and present
value accordingly

tools headers: Sync the various kvm.h header copies

2018-10-31T12:57:53+00:00

For powerpc, s390, x86 and the main uapi linux/kvm.h header, none of
them entail changes in tooling.

tools headers powerpc: Update asm/unistd.h copy to pick new

2018-07-30T14:51:13+00:00

The new 'io_pgetevents' syscall was wired up in PowerPC in the following
cset:

  b2f82565f2ca ("powerpc: Wire up io_pgetevents")

Update tools/arch/powerpc/ copy of the asm/unistd.h file so that 'perf
trace' on PowerPC gets it in its syscall table.

This elliminated the following perf build warning:

  Warning: Kernel ABI header at 'tools/arch/powerpc/include/uapi/asm/unistd.h' differs from latest version at 'arch/powerpc/include/uapi/asm/unistd.h'

tools/headers: Pick up latest kernel ABIs

2018-06-26T06:43:14+00:00

Sync KVM ABI additions and x86 CPU features additions - neither of which
has any impact on the tooling build.

tools include powerpc: Update arch/powerpc/include/uapi/asm/unistd.h copy to get 'rseq' syscall

2018-06-25T14:59:36+00:00

This updates the tools/perf/ copy of the powerpc file used to generate
the syscall table file used to make 'perf trace' become aware of the new
'rseq' syscall, no matter in which system it gets built, i.e. older
systems where the syscalls are not available in the running kernel (via
tracefs) or in the system headers will still be aware of these
syscalls/.

From this commit:

  bb862b021d75 ("powerpc: Wire up restartable sequences system call")

Silencing this tools/perf build warning:

  Warning: Kernel ABI header at 'tools/arch/powerpc/include/uapi/asm/unistd.h' differs from latest version at 'arch/powerpc/include/uapi/asm/unistd.h'

tools include powerpc: Grab a copy of arch/powerpc/include/uapi/asm/unistd.h

2018-02-16T17:55:47+00:00

Will be used for generating the syscall id/string translation table.

Committer notes:

Update it already to catch with these csets applied since Ravi first
submitted this patch:

  3350eb2ea127 powerpc: sys_pkey_mprotect() system call
  9499ec1b5e82 powerpc: sys_pkey_alloc() and sys_pkey_free() system calls

So now 'perf trace' on ppc now knows about the pkey_ syscals.

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: Sync {tools/,}arch/powerpc/include/uapi/asm/kvm.h

2018-02-02T20:04:53+00:00

The changes in the 3214d01f139b ("KVM: PPC: Book3S: Provide information
about hardware/firmware CVE workarounds") commit right now will not
produce any change in the tools, but that is because we still need to
improve tools/perf/trace/beauty/kvm_ioctl.sh to build per arch string
tables, so that we avoid assigning multiple times to the same command
string entry, i.e. multiple defines, for different arches, have the same
value, causing this:

  In file included from trace/beauty/ioctl.c:82:0:
  /tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c: In function ‘ioctl__scnprintf_kvm_cmd’:
  /tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c:76:11: error: initialized field overwritten [-Werror=override-init]
  /tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c:88:11: note: (near initialization for ‘kvm_ioctl_cmds[165]’)
  /tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c:90:11: error: initialized field overwritten [-Werror=override-init]
    [0xa6] = "PPC_GET_SMMU_INFO",
             ^~~~~~~~~~~~~~~~~~~

So the onlye effect of updating the tools/ copy of ppc's kvm.h header
is to silence these perf build warnings:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/kvm.h' differs from latest version at 'include/uapi/linux/kvm.h'
  Warning: Kernel ABI header at 'tools/arch/powerpc/include/uapi/asm/kvm.h' differs from latest version at 'arch/powerpc/include/uapi/asm/kvm.h'

At some point we should do what we did for the errno tables and create
per-arch string translation tables for the KVM ioctl commands for the
architectures supporting KVM, such as s/390, PowerPC, x86_64 and ARM.

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.
