hi Mathieu:
But I have some question about trace collection and decode flow
- for trace collection, shall we ask perf to save some other places? such as USB or somewhere alse
We welcome patches.
got it and try to debug where to add.
- from HOWTO document, is perf.data the trace data from ETM?
The perf.data file contains the trace data from the ETM devices, the metadata associated with the ETM configuration and miscellaneous perf events recorded during the session.
Does that mean off-target-perf cannot decode pure trace data from ETM?
Not at this time. Perf expect information about a trace session to be part of the perf.data file but it wouldn't be hard to provide the same information from an input file or a script, it's just a matter of doing it.
thanks for your help in advance,
