Subject: [PATCH 21/31] x86/insn: perf tools: Add new memory instructions
Date: Fri, 4 Sep 2015 13:45:05 -0300 [thread overview]
Message-ID: <1441385115-6744-22-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1441385115-6744-1-git-send-email-acme@kernel.org>
From: Adrian Hunter <adrian.hunter@intel.com>
Intel Architecture Instruction Set Extensions Programing Reference (Oct
2014) describes 3 new memory instructions, namely clflushopt, clwb and
pcommit. Add them to the op code map and the perf tools new
instructions test. e.g.
$ tools/perf/perf test "x86 ins"
39: Test x86 instruction decoder - new instructions : Ok
Or to see the details:
$ tools/perf/perf test -v "x86 ins"
