perf sched: Add support for sched:sched_stat_runtime events
This allows more precise 'perf sched latency' output: --------------------------------------------------------------------------------------- Task | Runtime ms | Switches | Average delay ms | Maximum delay ms | --------------------------------------------------------------------------------------- ksoftirqd/0-4 | 0.010 ms | 2 | avg: 2.476 ms | max: 2.977 ms | perf-12328 | 15.844 ms | 66 | avg: 1.118 ms | max: 9.979 ms | bdi-default-235 | 0.009 ms | 1 | avg: 0.998 ms | max: 0.998 ms | events/1-8 | 0.020 ms | 2 | avg: 0.998 ms | max: 0.998 ms | events/0-7 | 0.018 ms | 2 | avg: 0.992 ms | max: 0.996 ms | sleep-12329 | 0.742 ms | 3 | avg: 0.906 ms | max: 2.289 ms | sshd-12122 | 0.163 ms | 2 | avg: 0.283 ms | max: 0.562 ms | loop-getpid-lon-12322 | 1023.636 ms | 69 | avg: 0.208 ms | max: 5.996 ms | loop-getpid-lon-12321 | 1038.638 ms | 5 | avg: 0.073 ms | max: 0.171 ms | migration/1-5 | 0.000 ms | 1 | avg: 0.006 ms | max: 0.006 ms | --------------------------------------------------------------------------------------- TOTAL: | 2079.078 ms | 153 | ------------------------------------------------- Also, streamline the code a bit more, add asserts for various state machine failures (they should be debugged if they occur) and fix a few odd ends.
