perf kwork: Add sched record support
The kwork_class type of sched is added to support recording and parsing of
sched_switch events.
As follows:
# perf kwork -h
Usage: perf kwork [<options>] {record|report|latency|timehist}
-D, --dump-raw-trace dump raw trace in ASCII
-f, --force don't complain, do it
-k, --kwork <kwork> list of kwork to profile (irq, softirq, workqueue, sched, etc)
-v, --verbose be more verbose (show symbol address, etc)
# perf kwork -k sched record true
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.083 MB perf.data (47 samples) ]
# perf evlist
sched:sched_switch
dummy:HG
# Tip: use 'perf evlist --trace-fields' to show fields for tracepoint events
