2024-06-15perf: sched map skips redundant lines with cpu filtersFernand Sieber1-6/+6
perf sched map supports cpu filter. However, even with cpu filters active, any context switch currently corresponds to a separate line. As result, context switches on irrelevant cpus result to redundant lines, which makes the output particlularly difficult to read on wide architectures. Fix it by skipping printing for irrelevant CPUs.

After debugging, this turned out to be a timing issue. The benchmark creates threads equal to number of cpus and issues a futex_wait. Then it does a usleep for .1 second before initiating futex_wake. In system configuration with more threads, the usleep time is not enough. Patch changes the usleep from 100000 to 200000 With the patch, ran multiple iterations and there were no issues further seen Reported-by: Disha Goel <disgoel@linux.vnet.ibm.com> Signed-off-by: Athira Rajeev <atrajeev@linux.vnet.ibm.com> Reviewed-by: Ian Rogers <irogers@google.com> Tested-by: Disha Goel <disgoel@linux.ibm.com> Cc: akanksha@linux.ibm.com Cc: kjain@linux.ibm.com Cc: maddy@linux.ibm.com Cc: linuxppc-dev@lists.ozlabs.org Signed-off-by: Namhyung Kim <namhyung@kernel.org> Link: https://lore.kernel.org/r/20240607044354.82225-3-atrajeev@linux.vnet.ibm.com

2024-06-10perf evsel: Refactor tool eventsIan Rogers4-45/+277
Tool events unnecessarily open a dummy perf event which is useless even with `perf record` which will still open a dummy event. Change the behavior of tool events so: - duration_time - call `rdclock` on open and then report the count as a delta since the start in evsel__read_counter. This moves code out of builtin-stat making it more general purpose. - user_time/system_time - open the fd as either `/proc/pid/stat` or `/proc/stat` for cases like system wide. evsel__read_counter will read the appropriate field out of the procfs file. These values were previously supplied by wait4, if the procfs read fails then the wait4 values are used, assuming the process/thread terminated. By reading user_time and system_time this way, interval mode, per PID and per CPU can be supported although there are restrictions given what the files provide (e.g. per PID can't be combined with per CPU). Opening any of the tool events for `perf record` is changed to return invalid.

2024-06-07perf stat: Choose the most disaggregate command line optionIan Rogers1-21/+52
When multiple aggregation options are passed to perf stat the behavior isn't clear. Consider "perf stat -A --per-socket .." and "perf stat --per-socket -A ..", the first won't aggregate at all while the second will do per-socket aggregation, even though the same options were passed. Rather than set an enum value, gather the options in a struct and process them from most to least aggregate. This ensures the least aggregate option always applies, so no aggregation if "-A" is passed.
