Hello, I'm curious if there are any planned updates to apmd with regards to exposing a means for a user to set which c-state a processor should go into.
See this prior mailing list thread for context: http://comments.gmane.org/gmane.os.openbsd.misc/209854 The reason I ask is that when looking at this comment from December 2014 [1], and doing some reading about what intel_powerclamp is doing [2], I think that it could be very beneficial for battery life to force the CPU into a higher c-state when idle. As of 5.4-current, MWAIT is going to C1 when idle in all cases [3], and I wish to know if that's changed since.
