[v5] perf sched: Introduce stats tool

[PATCH v5 02/10] perf header: Support CPU DOMAIN relation info

Posted by Swapnil Sapkal 2 weeks, 4 days ago

'/proc/schedstat' gives the info about load balancing statistics within
a given domain. It also contains the cpu_mask giving information about
the sibling cpus and domain names after schedstat version 17. Storing
this information in perf header will help tools like `perf sched stats`
for better analysis.

As always thanks for the testing! I believe this issue is addressed by:
https://lore.kernel.org/lkml/20260122213516.671089-2-irogers@google.com/
which is merged into the perf-tools-next tree:
https://web.git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools-next.git/commit/?h=perf-tools-next&id=d84f24c898864facc13412a58b78964f6a769d76

Thanks,
Ian

You should likely make cpumask and cpulist as NR_CPUS to be
safe.

256 will work till 1024 CPUs no? These days there are systems with
more CPUs than that.

Making it NR_CPUS will likely cover all crazy cases/configurations.
