Subject: [PATCH 56/85] perf stat: Support per-die aggregation
Date: Tue, 11 Jun 2019 15:58:42 -0300 [thread overview]
Message-ID: <20190611185911.11645-57-acme@kernel.org> (raw)
In-Reply-To: <20190611185911.11645-1-acme@kernel.org>
From: Kan Liang <kan.liang@linux.intel.com>
It is useful to aggregate counts per die. E.g. Uncore becomes die-scope
on Xeon Cascade Lake-AP.
Introduce a new option "--per-die" to support per-die aggregation.
The global id for each core has been changed to socket + die id + core
id. The global id for each die is socket + die id.
Add die information for per-core aggregation. The output of per-core
aggregation will be changed from "S0-C0" to "S0-D0-C0". Any scripts
which rely on the output format of per-core aggregation probably be
broken.
For 'perf stat record/report', there is no die information when
processing the old perf.data. The per-die result will be the same as
per-socket.
Committer notes:
Renamed 'die' variable to 'die_id' to fix the build in some systems:
CC /tmp/build/perf/builtin-script.o
cc1: warnings being treated as errors
builtin-stat.c: In function 'perf_env__get_die':
builtin-stat.c:963: error: declaration of 'die' shadows a global declaration
util/util.h:19: error: shadowed declaration is here
mv: cannot stat `/tmp/build/perf/.builtin-stat.o.tmp': No such file or directory
