Subject: [PATCH 34/61] perf c2c report: Add hitm/store percent related sort keys
Date: Mon, 19 Sep 2016 15:09:43 +0200 [thread overview]
Message-ID: <1474290610-23241-35-git-send-email-jolsa@kernel.org> (raw)
In-Reply-To: <1474290610-23241-1-git-send-email-jolsa@kernel.org>
Adding hitm/store percent dimension key wrappers.
They are to be displayed in the single cacheline output:
percent_rmt_hitm, percent_lcl_hitm, percent_stores_l1hit, percent_stores_l1miss
They display percentage of HITMs/stores for specific
offset in the cacheline.
