@thac0 just shared an interesting article presenting a practical case study of how get a reference platform to idle deeply on Clear Linux OS. It is meant to provide first-pass guidance for integrators trying to increase energy efficiency on their Intel platform—running Linux—during idle.
By default, many Linux distributions do not aggressively enable power management features in devices, instead they err on the side of stability to the detriment of energy efficiency. However, “bad” tunable have the potential to prevent the platform from deeply idling.
In contrast, Clear Linux OS introduced clr-power-tweaks early in its inception. This optimization is a simple program, run at boot time, that enables power management features on a known-good-list of devices on various buses.
