Hi Leo,

Yeah I agree the redundant AUX events are adding unnecessary bloat to
the perf.data file... We actually cam across this when doing one of the
test cases. Sorry for not reporting it!
No worries.
Could we patch the driver in a separate patch set? Or do you think this
is critical for the purposes of this one?
Yeah, we can take low priority for the redundant AUX events issue.

Please take a look for the issue mentioned in another email for
recording trace data with wrong size.  I think the issue for wrong
snapshot trace size should have a fixing in Arm SPE driver, and the
fixing need to be verified with the perf patches.  After that I am fine
for merging the perf patches (and you could upstream kernel driver
patches separately).  How about you think?

Thanks,
Leo
