perf mem: Scan all PMUs instead of just core ones
Scanning only core PMUs is not sufficient on platforms like AMD since
perf mem on AMD uses IBS OP PMU, which is independent of core PMU.
Scan all PMUs instead of just core PMUs. There should be negligible
performance overhead because of scanning all PMUs, so we should be okay.

This looks like something that address/memory sanitizers could help with.

This function is quite different in latest perf-tools tree. Do you see failure
with latest perf as well? Unfortunately, I don't have hybrid machine to try
myself.

I think it is just that the shell script pipes the output and so we
don't see it in verbose mode. I'd add a "set -x" to
tools/perf/tests/shell/test_data_symbol.sh so you can run the failing
command without the redirects/pipes/..

Memory is stashed into a priv field here:
https://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools-next.git/tree/tools/perf/util/hist.c#n828
There is a comment saying that clean up isn't necessary:
https://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools-next.git/tree/tools/perf/util/hist.c#n884
but it seems something has broken that.

This is a real leak:
https://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools-next.git/tree/tools/perf/util/mem-events.c?h=perf-tools-next#n261
the record args probably all need to be strdup-ed and then each array
entry freed when the array is freed.
Thanks,
Ian
