Subject: Re: [PATCH 8/8] perf: Add the timechart tool


there's also a few other infrastructure things that should be improved:

 - struct wake_event / trace_entry / wakeup_entry / sched_switch etc. 
   are all present in the existing tracing bits or in builtin-sched. 
   These should be factored out into common facilities and shared 
   between perf timechart and perf sched. We in essence want a good 
   facility to access tracepoint data.

 - the kernel side scheduler tracepoints relied on here should be 
   updated from TRACE_EVENT to TRACE_EVENT_ABI. (TRACE_EVENT_ABI should 
   just be an alias of TRACE_EVENT)
