From ac1c8859a81e2fc45db1dbff30bdc572005734ca Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Wed, 2 Sep 2015 15:15:29 +0300 Subject: [PATCH] x86/insn: perf tools: Add new memory instructions 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" Signed-off-by: Adrian Hunter Acked-by: Masami Hiramatsu Cc: "H.
