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) ?
