In previous patch, we have supported the syntax which enables the event on a specified pmu, such as: cpu_core/<event>/ cpu_atom/<event>/ While this syntax is not very easy for applying on a set of events or applying on a group. In following example, we have to explicitly assign the pmu prefix. # ./perf stat -e '{cpu_core/cycles/,cpu_core/instructions/}' -- sleep 1 Performance counter stats for 'sleep 1': 1,158,545 cpu_core/cycles/ 1,003,113 cpu_core/instructions/ 1.002428712 seconds time elapsed A much easier way is: # ./perf stat --cputype core -e '{cycles,instructions}' -- sleep 1 Performance counter stats for 'sleep 1': 1,101,071 cpu_core/cycles/ 939,892 cpu_core/instructions/ 1.002363142 seconds time elapsed For this example, the '--cputype' enables the events from specified pmu (cpu_core). If '--cputype' conflicts with pmu prefix, '--cputype' is ignored. # ./perf stat --cputype core -e cycles,cpu_atom/instructions/ -a -- sleep 1 Performance counter stats for 'system wide': 21,003,407 cpu_core/cycles/ 367,886 cpu_atom/instructions/ 1.002203520 seconds time elapsed Signed-off-by: Jin Yao <yao.jin@linux.intel.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Jin Yao <yao.jin@intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lore.kernel.org/lkml/20210909062215.10278-1-yao.jin@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
