Please note that some processing of your personal data may not require your consent, but you have a right to object to such processing. sudo nano /etc/cpupower_gui. Core2 Quad are ancient CPUs and intel_pstate=powersave even still sucks with my 6700k. However, you can tell it to use a different governor while running, so if you want to effectively set the default without recompiling, you can add something to /etc/rc. Energy Aware Scheduling (or EAS) gives the scheduler the ability to predict the impact of its decisions on the energy consumed by CPUs. It is to fine tune the processor configuration on amd-pstate to the schedutil with CPU CFS scheduler. Hikey vs. current CPU frequency: Unable to call hardware current CPU frequency: 4.
