Thanks for your reply ,David Long. Can you give me url of the kernel version 3.4.19?Thanks.

I suggest checking out the "tilt-3.4" branch of git://git.linaro.org/landing-teams/working/ti/kernel.git

That is based on 3.4.20.

git clone git://git.linaro.org/landing-teams/working/ti/kernel.git cd kernel git checkout --track tilt-3.4

Looks like omap4plus_defconfig already has what you need for hardware perf counters.
