Subject: [PATCH 3/4] perf/powerpc: add support for PERF_SAMPLE_BRANCH_CALL
Date: Tue, 13 Oct 2015 09:09:10 +0200 [thread overview]
Message-ID: <1444720151-10275-4-git-send-email-eranian@google.com> (raw)
In-Reply-To: <1444720151-10275-1-git-send-email-eranian@google.com>
The patch catches PERF_SAMPLE_BRANCH_CALL because it is not clear whether
this is actually supported by the hardware.
Signed-off-by: Stephane Eranian <eranian@google.com>
