Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: . Make some POWER7 events available in sysfs, equivalent to what was done on x86, from Sukadev Bhattiprolu. . Add event group view, from Namyung Kim: To use it, 'perf record' should group events when recording. And then perf report parses the saved group relation from file header and prints them together if --group option is provided. You can use 'perf evlist' command to see event group information: $ perf record -e '{ref-cycles,cycles}' noploop 1 [ perf record: Woken up 2 times to write data ] [ perf record: Captured and wrote 0.385 MB perf.data (~16807 samples) ] $ perf evlist --group {ref-cycles,cycles} With this example, default perf report will show you each event separately like this: $ perf report ... # group: {ref-cycles,cycles} # ======== # Samples: 3K of event 'ref-cycles' # Event count (approx.): 3153797218 # # Overhead Command Shared Object Symbol # ........ ....... ................. .......................... 99.84% noploop noploop [.] main 0.07% noploop ld-2.15.so [.] strcmp 0.03% noploop [kernel.kallsyms] [k] timerqueue_del 0.03% noploop [kernel.kallsyms] [k] sched_clock_cpu 0.02% noploop [kernel.kallsyms] [k] account_user_time 0.01% noploop [kernel.kallsyms] [k] __alloc_pages_nodemask 0.00% noploop [kernel.kallsyms] [k] native_write_msr_safe # Samples: 3K of event 'cycles' # Event count (approx.): 3722310525 # # Overhead Command Shared Object Symbol # ........ ....... ................. ......................... 99.76% noploop noploop [.] main 0.11% noploop [kernel.kallsyms] [k] _raw_spin_lock 0.06% noploop [kernel.kallsyms] [k] find_get_page 0.03% noploop [kernel.kallsyms] [k] sched_clock_cpu 0.02% noploop [kernel.kallsyms] [k] rcu_check_callbacks 0.02% noploop [kernel.kallsyms] [k] __current_kernel_time 0.00% noploop [kernel.kallsyms] [k] native_write_msr_safe In this case the event group information will be shown in the end of header area. So you can use --group option to enable event group view. $ perf report --group ... # group: {ref-cycles,cycles} # ======== # Samples: 7K of event 'anon group { ref-cycles, cycles }' # Event count (approx.): 6876107743 # # Overhead Command Shared Object Symbol # ................ ....... ................. .......................... 99.84% 99.76% noploop noploop [.] main 0.07% 0.00% noploop ld-2.15.so [.] strcmp 0.03% 0.00% noploop [kernel.kallsyms] [k] timerqueue_del 0.03% 0.03% noploop [kernel.kallsyms] [k] sched_clock_cpu 0.02% 0.00% noploop [kernel.kallsyms] [k] account_user_time 0.01% 0.00% noploop [kernel.kallsyms] [k] __alloc_pages_nodemask 0.00% 0.00% noploop [kernel.kallsyms] [k] native_write_msr_safe 0.00% 0.11% noploop [kernel.kallsyms] [k] _raw_spin_lock 0.00% 0.06% noploop [kernel.kallsyms] [k] find_get_page 0.00% 0.02% noploop [kernel.kallsyms] [k] rcu_check_callbacks 0.00% 0.02% noploop [kernel.kallsyms] [k] __current_kernel_time As you can see the Overhead column now contains both of ref-cycles and cycles and header line shows group information also - 'anon group { ref-cycles, cycles }'. The output is sorted by period of group leader first. If perf.data file doesn't contain group information, this --group option does nothing. So if you want enable event group view by default you can set it in ~/.perfconfig file: $ cat ~/.perfconfig [report] group = true It can be overridden with command line if you want: $ perf report --no-group Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Ingo Molnar <mingo@kernel.org>
