Hi Xen Users!

I'm currently running Qubes 4.1 (Xen 4.13.1) on an AMD Ryzen 4750U APU, the specific laptop is a Lenovo X13 (AMD).

I can see Xen boot up, however when dom0 boots, I don't see any output. I speculate this is because dom0 can't write/map into the UMA Framebuffer.

This seems to be related to UMA / iGPU Memory Management.

efifb: cannot reserve video memory at 0x60000000
efi: EFI_MEMMAP is not enabled

I can't seem to see any AMD/Ryzen specific commits that are newer than 4.13.1, I was looking at cherry picking Xen commits related to AMD/Ryzen however I can't find any.
