* The defconfigs from the RPi Kernel set `powersave` as the default CPU governor, which is a bad idea as that reduces performance by setting the CPU frequency to the minimum one. * In case of a Yocto build user-space is not configured by default to change the CPU governor, so `powersave` will remain the CPU governor and it will slow down everything. * I submitted a fix for those defconfigs to upstream here: https://github.com/raspberrypi/linux/pull/5666 However, we shouldn't wait until that is accepted and backported to all the stable branches (if ever is). * This patch unsets the selection of `powersave` as the default CPU governor. * Then the CPU governor that will be selected as default after this patch will be the Linux's default one that is either `ondemand` or `schedutil` depending on the Kernel version.
