Hi
Here is V4 of PERF_RECORD_SWITCH.
Changes in V4:
perf: Add PERF_RECORD_SWITCH to indicate context switches
Use a separate record format PERF_RECORD_SWITCH_CPU_WIDE
for the CPU-wide case that includes the next/previous pid/tid
perf tools: Add new PERF_RECORD_SWITCH event
Amended to handle PERF_RECORD_SWITCH_CPU_WIDE
perf record: Add option --switch-events to select PERF_RECORD_SWITCH events
Add PERF_RECORD_SWITCH_CPU_WIDE to documentation
perf script: Don't assume evsel position of tracking events
New patch
perf script: Add option --show-switch-events
Add PERF_RECORD_SWITCH_CPU_WIDE to documentation
Changes in V3:
Rename 'perf_event_switch()' parameter 'out' to be 'sched_in'
and invert meaning.
Changes in V2 (RFC):
The event now shows scheduling in and out,
and I added next/prev pid/tid for cpu-wide
contexts, plus there are some tools patches
that apply to Arnaldo's perf/core branch.
