About CpuTopologyRebuild.kext [Important]

This kext spoof e-core as logical core of p-core, which increases the chance of p-core being scheduled in 12-gen heterogeneous CPUs, resulting in better single-thread performance (especially in Virtual Machine).
So, If your CPU is not 12600(f/k/kf)/12700(f/k/kf)/12900(f/k/kf), remove this kext and remove the -ctrsmt boot args!!!

Support for other AMD GPUs

This EFI supports 6000 Series AMD GPUs.

For 5000 series and below, see AMD GPUs # for more details.

About USB map

Maybe you need to make some changes to suit your USB and case, current usb mapping is from yzchan(thanks yzchan for saved us a lot of time).

Disbale NVMe drive

If you want to disable a NVMe drive that doesn't support hackintosh, just enable ACPI - Add - SSDT-DNVMe.aml, it will disable the NVMe drive which inserted into M.2 slot 1.

You can also change _SB_.PC00.PEG0.PEGP to disable other NVMe drive or PCIE devices. See: fixing-nvme for more details
