support PMU/perf on OMAP4

[Fan Ye]

Hi,

I am currently working on Pandaboard and want to make PMU interrupt work. I notice that you have a patch to enable pmu/perf support on OMAP4:

Can you please tell me on which code base of the kernel the patch is working?

I am using minimal FS on pandaboard. But the patch does not work. I find the PMU interrupt is not triggered.

Thanks a lot in advance.
Ye Fan
