There was a problem hiding this comment.
For now, yes. I assume it will end up slightly different in the end, which is why i didn't reuse the struct.

I'm not comfortable merging this until we at least confirm via macOS HV trace that it does the same thing. Getting this wrong has bit us hard in the past (M2 core lockups on deep sleep) and it's a huge nightmare to debug. We're going to need the HV for a lot of other stuff on M3 anyway, so there isn't much point in bringing up Linux cpufreq until that works. |

That's fine.

Note: I traced enough of the kext now to verify that this is at least as correct as the current other code :) But I still agree we should basically leave it disabled until we have lots of other stuff working, just to eliminate variables. |
