Subject: [PATCH 02/11] perf tools mem: Fix -t store option for record command
Date: Mon, 15 Aug 2016 18:46:18 -0300 [thread overview]
Message-ID: <1471297587-1229-3-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1471297587-1229-1-git-send-email-acme@kernel.org>
From: Jiri Olsa <jolsa@kernel.org>
Michael reported 'perf mem -t store record' being broken. The reason is
latest rework of this area:
commit acbe613e0c03 ("perf tools: Add monitored events array")
We don't mark perf_mem_events store record when -t store option is
specified.
Committer notes:
Before:
# perf mem -t store record usleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.020 MB perf.data (7 samples) ]
# perf evlist
cycles:ppp
#
After:
# perf mem -t store record usleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.020 MB perf.data (7 samples) ]
# perf evlist
cpu/mem-stores/P
