CONFIG_MMC_PERF_PROFILING=y
Other necessary configuration:
CONFIG_HAVE_PERF_EVENTS=y
CONFIG_PERF_EVENTS=y
CONFIG_PERF_COUNTERS=y
are absent and thus not compiled as "y". Recompiling the kernel + setting up the kernel for ARM is necessary, but the basic core perf files are available in this version though.

Hello Sandeep,
you need an ARM toolchain to compile the perf userspace tool, which is
the second thing you need in order to use perf on a machine (the first
thing is the kernel stuff, which you already have). So the things you
have to do is
(1) compile/install your own ARM toolchain and compile all libraries
which are needed for perf or
(2) find a static perf compiled for ARM which you can copy to your device.

Philipp
