OcAppleKernelLib: Investigate MSR_MISC_PWR_MGMT (0x199) behavior on macOS 12+ #2410

Closed PMheart closed 2 weeks ago

PMheart commented 3 weeks ago

macOS 15 beta 1 has writes to MSR_MISC_PWR_MGMT (0x199) completely removed. No, this was removed as early as on macOS 12 beta 1, in June 2021.

It is still unsure whether this is a bug of XNU, or this was done intentionally. We shall wait for the next few betas, and if necessary, start the investigation of new XCPM routines.

As these platforms become obsolete, this issue is downgraded to low priority.

It is assumed that writes to MSR_MISC_PWR_MGMT (0x199) no longer exist on macOS 12+. Closing.
