perf evsel: Fix the annotation for hardware events on hybrid
The annotation for hardware events is wrong on hybrid. For example, # ./perf stat -a sleep 1 Performance counter stats for 'system wide': 32,148.85 msec cpu-clock # 32.000 CPUs utilized 374 context-switches # 11.633 /sec 33 cpu-migrations # 1.026 /sec 295 page-faults # 9.176 /sec 18,979,960 cpu_core/cycles/ # 590.378 K/sec 261,230,783 cpu_atom/cycles/ # 8.126 M/sec (54.21%) 17,019,732 cpu_core/instructions/ # 529.404 K/sec 38,020,470 cpu_atom/instructions/ # 1.183 M/sec (63.36%) 3,296,743 cpu_core/branches/ # 102.546 K/sec 6,692,338 cpu_atom/branches/ # 208.167 K/sec (63.40%) 96,421 cpu_core/branch-misses/ # 2.999 K/sec 1,016,336 cpu_atom/branch-misses/ # 31.613 K/sec (63.38%) The hardware events have extended type on hybrid, but the evsel__match() doesn't take it into account. Filter the config on hybrid before checking. With the patch, # ./perf stat -a sleep 1 Performance counter stats for 'system wide': 32,139.90 msec cpu-clock # 32.003 CPUs utilized 343 context-switches # 10.672 /sec 32 cpu-migrations # 0.996 /sec 73 page-faults # 2.271 /sec 13,712,841 cpu_core/cycles/ # 0.000 GHz 258,301,691 cpu_atom/cycles/ # 0.008 GHz (54.20%) 12,428,163 cpu_core/instructions/ # 0.91 insn per cycle 37,786,557 cpu_atom/instructions/ # 2.76 insn per cycle (63.35%) 2,418,826 cpu_core/branches/ # 75.259 K/sec 6,965,962 cpu_atom/branches/ # 216.739 K/sec (63.38%) 72,150 cpu_core/branch-misses/ # 2.98% of all branches 1,032,746 cpu_atom/branch-misses/ # 42.70% of all branches (63.35%) Suggested-by: Ian Rogers <[email protected]> Reviewed-by: Ian Rogers <[email protected]> Signed-off-by: Kan Liang <[email protected]> Cc: Adrian Hunter <[email protected]> Cc: Ahmad Yasin <[email protected]> Cc: Andi Kleen <[email protected]> Cc: Ingo Molnar <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: Namhyung Kim <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Stephane Eranian <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>
