Hi, There is only very early work on intel_pstate driver (what Intel processors have moved towards for power management. AMD has similar with cool'n'quiet). https://github.com/jcs/openbsd-src/commit/29edcdbd593388193af3e1461f4432c6c94ff5b2 I believe the lowest C-state that OpenBSD supports is C3. The OpenBSD Intel KMS stack also doesn't expose some power management related tunables for Intel GPUs. For me it is the difference between 7.5W and 15W which is insignificant for cost but not insignificant for battery life. Unfortunately power management related code is pretty difficult to write unless you know the hardware very well. Basically, for now, run you machines warm and be... proud! ;) Best regards, Karsten
