Re: [tracecompass-dev] tracecompass Resources view doesn't make sense
|
I might be able to help here.
The views don't depend on LTTng per-se. The events are mapped to
intermediate ones like (hardware IRQ entry - exit)
So it should work, it worked with windows traces. But the mapping needs
to be correct and it is an area that is untested.
@Alexandre If you have some perf-ctf traces lying around, and could put
them in the test git (I don't have access to it), we could better test perf.
BR,
Matthew.
