Hi
Here is another look at PERF_RECORD_SWITCH. 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.
Adrian Hunter (4): perf: Add PERF_RECORD_SWITCH to indicate context switches perf tools: Add new PERF_RECORD_SWITCH event perf record: Add option --switch-events to select PERF_RECORD_SWITCH events perf script: Add option --show-switch-events
