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.
