Sorry about the mistake. Resending the answer again: I think it is not so simple. For example, for my Sony Ericsson, and from here: http://developer.sonymobile.com/wp/2011/05/06/how-to-build-a-linux-kernel/ I downloaded the kernel 4.0.2.A.0.42.tar.bz2 kernel, and from the semc_anzu_config file: 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.

I downloaded the kernel 4

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.
Greetings,
Philipp
