Wrt. perf support on ARM A9, I think the builtin PMU can work well with mainline kernel. > without oprofile.timer=1 kernel option, at least for Linus' tree; I didn't use oprofile before and always use 'perf', and I am sure it works well with arm a9 pmu hardware on linus tree. > searching gives a lot of discussion/patches fragments and similar > stuff, but I was unable to find a complete patch/git tree/whatever > else to try. I only know some patches[1][2] are needed for omap4, but all are omap4 hardware specific and nothing to do with arm a9 pmu.
