scripts/perf: Tag PM data with current run_test() instanceAdd signal handler to catch USR1 and drive re-tagging of the PM data.This should allow for a quick cross-reference while troubleshootingtarget test and its potential impact on the system.Change-Id: I6eb7ff0ed0fc4d0162db0166543a070a4ad90de4Signed-off-by: Michal Berger Reviewed-on: https://review.spdk.io/gerrit/c/spdk/spdk/+/21179Tested-by: SPDK CI Jenkins Reviewed-by: Konrad Sztyber Reviewed-by: Tomasz Zawadzki List of files: /spdk/scripts/perf/pm/collect-cpu-load

59c811f09c59a488bebe73d72d1f0f3a6d494808 - scripts/perf: Add tool for collecting cpu load

scripts/perf: Add tool for collecting cpu loadAs we are at it, remove bottleneck in get_cpu_time() - avoid reading/proc/stat line by line to find target cpu as in case of systems withhundreds of cpus this increases the get_cpu_time()'s runtime quitesignificantly. Instead, slurp all cpu stats with a single read andexpose them as _cpuN[].On a system with 144 cpus single get_cpu_time()'s iteration droppedfrom ~5s to ~1s.Note that this tool uses plain integer arithmetic so the results percpu time may be a bit off due to lacking precision. Nevertheless,they should serve nicely as an approximation.Change-Id: I64fecb593c5c38e3db79f75dcc4f23a9069c701aSigned-off-by: Michal Berger Reviewed-on: https://review.spdk.io/gerrit/c/spdk/spdk/+/21173Reviewed-by: Konrad Sztyber Tested-by: SPDK CI Jenkins Reviewed-by: Tomasz Zawadzki List of files: /spdk/scripts/perf/pm/collect-cpu-load
