xcpm #32

Closed technicalflaw closed 4 years ago

technicalflaw commented 4 years ago

In the Clover Conversion guide, Kernel and Kext Patches => KernelXCPM is stated as being equivalent to Kernel -> Quirks -> AppleXcpmExtraMsrs -> YES. It might be helpful to link to https://github.com/acidanthera/bugtracker/issues/365 which references additional _xcpm_bootstrap patches which may be needed.

It's probably not practical to list the many possible XCPM patches, but they can be converted from rEFIt_UEFI/Platform/kernel_patcher.c in the Clover source (although, for Google's sake, here's the Ivy Bridge patch for Catalina, taken from the KernelIvyBridgeXCPM() method of the aforementioned file)
