GPU support for Ampere Altra?

With the emulator in place, the next thing would be adding support for UEFI GOP console on GPUs other than the built in BMC This would be useful even without the emulator as modern AMD cards like my RX 6800 have a arm64 option rom/GOP driver built in from the get go.

Well, this already works, sort of. I you load the ARM64 GOP driver, which can be done automatically, the GPU will kick in just after the ASRockRack splash screen, in grub. And from grub you can jump to the UEFI setup and run it from your main gpu. This might work for rEFInd too, which would even be better.

Unfortunately, this method works for AMD cards only, not for NVidia or Intel, as they lack an ARM64 GOP.
