Samples produced by perf record can include process names that contain the cpu number in them. For example 'ksoftirqd/32', 'migration/16', etc. Introduce an option called 'aggregate-comm' for replacing the numerical part with '/all' such that the stacks could be combined. This makes flamegraphs for perf records captured on many cpus more legible. Signed-off-by: Cosmin Ratiu <[email protected]>
Samples produced by perf record can include process names that contain cpu-related suffixes in them. For example 'ksoftirqd/32', 'migration/16', 'kworker/u1025:1', etc. Introduce an option called 'aggregate-comm' for replacing the suffix with '/all' such that related stacks could be combined. This makes flamegraphs for perf records captured on many cpus more legible. Signed-off-by: Cosmin Ratiu <[email protected]>
