Subject: [PATCH v2 0/2] perf: add new option '--workload-attr' to set workload sched_policy/priority/mask
This adds a new option '--workload-attr' to set the sched_policy/priority/mask
of the workload to reduce system noise.
$ sudo perf stat --workload-attr fifo,40,0-3:7 -- ls
Please see patch 1/2 for more details.
v2:
- Use cpu list spec instead of cpu mask number.
- Update documents.
Changbin Du (2):
perf cpumap: Add __perf_cpu_map__new and perf_cpu_map__2_cpuset
