				bdragonAuthorUnsubmitted Done Inline Actions This seems pretty janky btw. Resetting the timebase to 0 seems like it would break all sorts of stuff when doing suspend/resume. We should probably look into this at some point and restore the timebase in a more disciplined manner (even on uniprocessor) bdragon: This seems pretty janky btw.

				jhibbitsUnsubmitted Done Inline Actions Yeah, may as well just #ifndef powerpc64 this, since it's only really going to be used on G4, and do a direct 'mttb(0)'. It will be properly restored later on. jhibbits: Yeah, may as well just #ifndef __powerpc64__ this, since it's only really going to be used on…
				bdragonAuthorUnsubmitted Done Inline Actions fwiw, in cpu_sleep(), for things to work at all on SMP, we would need to IPI the other processors into doing the sync with us. Is PMU frequency control ever enabled for SMP machines, or are we safe there? bdragon: fwiw, in cpu_sleep(), for things to work at all on SMP, we would need to IPI the other…
				jhibbitsUnsubmitted Done Inline Actions PMU frequency control is, to the best of my knowledge, only on PowerBooks, which are UP. jhibbits: PMU frequency control is, to the best of my knowledge, only on PowerBooks, which are UP.
