<br>I downloaded the kernel 4.0.2.A.0.42.tar.bz2 kernel, and from the semc_anzu_config file:</div><div><br></div><div><div>CONFIG_MMC_PERF_PROFILING=y</div></div><div><br></div><div>Other necessary configuration:</div><div>

Recompiling the kernel + setting up the kernel for ARM is necessary, but the basic core perf files are available in this version though.</div>

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