scripts/analyse-locks-simpletrace.py: script to analyse lock times
This script allows analysis of mutex acquisition and hold times based
on a trace file. Given a trace control file of:
qemu_mutex_lock
qemu_mutex_locked
qemu_mutex_unlock
And running with:
$QEMU $QEMU_ARGS -trace events=./lock-trace
You can analyse the results with:
./scripts/analyse-locks-simpletrace.py trace-events-all ./trace-21812
