perf stat: Reduce min --interval-print to 10ms (2015-10-02 17:07:55 -0300)
---------------------------------------------------------------- perf/core improvements and fixes:
User visible:
- Do event name substring search as last resort in 'perf list'. (Arnaldo Carvalho de Melo)
E.g.:
# perf list clock
List of pre-defined events (to be used in -e):
cpu-clock [Software event] task-clock [Software event]
uncore_cbox_0/clockticks/ [Kernel PMU event] uncore_cbox_1/clockticks/ [Kernel PMU event]
kvm:kvm_pvclock_update [Tracepoint event] kvm:kvm_update_master_clock [Tracepoint event] power:clock_disable [Tracepoint event] power:clock_enable [Tracepoint event] power:clock_set_rate [Tracepoint event] syscalls:sys_enter_clock_adjtime [Tracepoint event] syscalls:sys_enter_clock_getres [Tracepoint event] syscalls:sys_enter_clock_gettime [Tracepoint event] syscalls:sys_enter_clock_nanosleep [Tracepoint event] syscalls:sys_enter_clock_settime [Tracepoint event] syscalls:sys_exit_clock_adjtime [Tracepoint event] syscalls:sys_exit_clock_getres [Tracepoint event] syscalls:sys_exit_clock_gettime [Tracepoint event] syscalls:sys_exit_clock_nanosleep [Tracepoint event] syscalls:sys_exit_clock_settime [Tracepoint event]
- Reduce min 'perf stat --interval-print/-I' to 10ms (Kan Liang)
perf stat --interval in action:
# perf stat -e cycles -I 50 -a usleep $((200 * 1000)) print interval < 100ms. The overhead percentage could be high in some cases. Please proceed with caution. # time counts unit events 0.050233636 48,240,396 cycles 0.100557098 35,492,594 cycles 0.150804687 39,295,112 cycles 0.201032269 33,101,961 cycles 0.201980732 786,379 cycles #
- Allow for max_stack greater than PERF_MAX_STACK_DEPTH, as when synthesizing callchains from Intel PT data (Adrian Hunter)
- Allow probing on kmodules without DWARF (Masami Hiramatsu)
- Fix a segfault when processing a perf.data file with callchains using "perf report --call-graph none" (Namhyung Kim)
- Fix unresolved COMMs in 'perf top' when -s comm is used (Namhyung Kim)
- Register idle thread in 'perf top' (Namhyung Kim)
- Change 'record.samples' type to unsigned long long, fixing output of number of samples in 32-bit architectures (Yang Shi)
