Music to my ears!

PS. If you did anything cool with trace compass, we would love to hear about it.

Hi Greg,

Cycle events are currently read and supported in the incubator patch "Perf Profiling", to install it, you need to go to "Tools" -> "Add ons..." and then you will see all the cool extra features in trace compass.

If there is a bug, please let us know. (or even better, push a fix and we'll gladly merge and shower you with praise. 🙂 )


Please keep us posted.
Matthew.

Hi all,

I have a trace file that was generated by running perf and converting the output to CTF format.  The file contains a bunch of "cycle" events (as well as other events such as perf_mmap).  The CTF file loads successfully into Trace Compass 7.3.0.  Should I expect to see "Flame Graph" or "Flame Chart" as an available node under Views node in Project Explorer?  

I'm not seeing either of those nodes.  Is there anything additional that I need to do in order to be presented with the option of opening a Flame graph or Flame chart from a CTF format file that has "cycle" events?

Any info appreciated; thanks!

Regards,
Greg
