[tracecompass-dev] Question about importing a multi-cpu perf capture in

[Jerome CORRENOZ <jerome.correnoz@xxxxxx>]

Hi,

 

I’m starting to use TraceCompass to import a perf trace.

 

I have a problem with multi-CPU. Indeed, the trace has been captured on a multi-CPU but all the events seem to be associated to CPU0 (see the table view, column “CPU”) whereas the “Contents” correctly contains the “perf_cpu=X”. This impacts the “Resources” view where only CPU0 is displayed but mainly the “Control Flow” view.

 

I’m using:

-    perf 4.1.1 on ARMv7

-    TraceCompass 1.1.0

 

Doing the following:

 

#perf record –e ‘sched :*’ –a

#perf data convert –to-ctf=./ctf

Then Open the ctf file (called perf_stream_0) in TraceCompass

 

Any ideas about the cause of it ?

 

BR,

  Jerome
