Subject: [PATCH 01/15] tools arch x86: Sync the msr-index.h copy with the kernel sources
Date: Tue, 14 Apr 2020 13:48:40 -0300	[thread overview]
Message-ID: <20200414164854.26026-2-acme@kernel.org> (raw)
In-Reply-To: <20200414164854.26026-1-acme@kernel.org>

From: Arnaldo Carvalho de Melo <acme@redhat.com>

To pick up the changes in:

  6650cdd9a8cc ("x86/split_lock: Enable split lock detection by kernel")

  Warning: Kernel ABI header at 'tools/arch/x86/include/asm/msr-index.h' differs from latest version at 'arch/x86/include/asm/msr-index.h'
  diff -u tools/arch/x86/include/asm/msr-index.h arch/x86/include/asm/msr-index.h

Which causes these changes in 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

Now one can do:

	perf trace -e msr:* --filter=msr==IA32_CORE_CAPS

or:

	perf trace -e msr:* --filter='msr==IA32_CORE_CAPS || msr==TEST_CTRL'

And see only those MSRs being accessed via:

  # perf trace -v -e msr:* --filter='msr==IA32_CORE_CAPS || msr==TEST_CTRL'
  New filter for msr:read_msr: (msr==0xcf || msr==0x33) && (common_pid != 8263 && common_pid != 23250)
  New filter for msr:write_msr: (msr==0xcf || msr==0x33) && (common_pid != 8263 && common_pid != 23250)
  New filter for msr:rdpmc: (msr==0xcf || msr==0x33) && (common_pid != 8263 && common_pid != 23250)
