Well perf should work itself OK using the fallback timer-based method,
it's specifically this -e mode.
The hardware counters are in there and do stuff, the problem is (IIRC
overflow) interrupts are prone to get lost, distorting the numbers to
uselessness, and that problem is in the ARM core and lay undiscovered
for a long while so is in all (AFAIK) shipping chips. So we disabled
them, as I say normal perf should be workable.
I think we have to, as you suggest, do a WONTFIX on it.
