Dear Mathieu,

Big thanks for this replaying.

Did you mean directly use the folder 'tools/perf' in perf-opencsd to replace the folder 'tools/perf' in laste mainline kernel?

No, I think Mathieu suggested you to use the mainline kernel completely, for building both kernel and 'tools/perf'.

Is it the same as directly using the 'tools/perf' in the last mainline kernel with the opencsd lib ?

perf-opencsd is relative old and it might be incompatible with the mainline kernel (e.g. if you are using kernel image from perf-opencsd and using perf tool from mainline kernel, it's likely not work).

Thanks, Leo
