But why is trace_power_start() adding a CPU ID argument? CPU ids are already available and can be sampled via PERF_SAMPLE_CPU if needed. AFAICS only power_frequency needs a new 'target_cpu_id' field. > diff --git a/tools/perf/builtin-timechart.c b/tools/perf/builtin-timechart.c > index 0d4d8ff..7809bef 100644 > --- a/tools/perf/builtin-timechart.c > +++ b/tools/perf/builtin-timechart.c Timechart is maintained by Arjan so we need an ack from him as well. I've seen some back and forth in the discussions - what's the technical resolution of that? (Also, there's some whitespace noise in the patch.)
