Subject: [RFC 0/3] perf tools: Add support for used defined metric
Date: Wed, 11 Dec 2019 23:47:57 +0100 [thread overview]
Message-ID: <20191211224800.9066-1-jolsa@kernel.org> (raw)
hi,
Joe asked for possibility to add user defined metrics. Given that
we already have metrics support, I added --metric option that allows
to specify metric on the command line, like:
# perf stat --metric 'DECODED_ICACHE_UOPS% = 100 * (idq.dsb_uops / \
(idq.ms_uops + idq.mite_uops + idq.dsb_uops + lsd.uops))' ...
The code facilitates the current metric code, and I was surprised
how easy it was, so I'm not sure I omitted something ;-)
Also available in:
git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
perf/metric
thoughts?
