* 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: raspberrypi/linux#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.

The defconfigs from the RPi Kernel set
powersaveas 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
powersavewill remain the CPU governor and it will slow down everything.I submitted a fix for those defconfigs to upstream here: configs: stop defaulting to the powersave governor raspberrypi/linux#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
powersaveas 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
ondemandorschedutildepending on the Kernel version.
