Hi Dave,
By the way, in http://lists.linaro.org/pipermail/linaro-dev/2011-September/thread.html#7560, we discussed about oprofile timer mode granularity for platforms, which had the PMU bug that loses PMU interrupts (4430, 4460 and maybe 4470). Was this timer granularity proposed/introduced ? Is it in fact part of perf infrastructure (don't know if perf relies directly on oprofile drivers/oprofile infrastructuret) ?
Regards Fred

So i ask you do ARM Cortex-A9 PMU supoort oprofile.
Can u help me?
In general, yes it does work. But board support is needed in addition to the CPU PMU support.
If you're trying to work on omap4 (panda) you may need some extra patches:
For more information on this, take a look at the following thread where this issue was discussed recently:
