No worries.

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
