At boot, Linux searches the /lib/firmware directory for binaries that it loads to the DSP, IPU, PRU, and EVE cores. The default binaries for example will wake DSP cores to run opencl acceleration then puts them to sleep when not in use. You can make up your own binaries for the above cores mentioned using the SDK examples provided below.
