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 Signed-off-by: Kan Liang <kan.liang@linux.intel.com> Reviewed-by: Jiri Olsa <jolsa@kernel.org> Cc: Andi Kleen <ak@linux.intel.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: https://lkml.kernel.org/n/tip-bsnhx7vgsuu6ei307mw60mbj@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
