Suggestion: Passing GPU to VM may allow BAR space...

[Rombutan]

I have no idea what Im talking about...

But while spinning up a qemu/kvm vm under fedora 34 on my AMD machine, I noticed in the 'Add Hardware'>'PCI Device', I see a binary option called 'ROM BAR', so perhaps this BAR space is actually virtualized, and thus could work on the CM4?

It would be pretty easy to try, just set up virt-manager, and whatever and then... check the box? You would also need to stub the gpu's pci address, at least on fedora, which does exist for arm devices.

Anyway if anyone wants to try its just one more quick thing that could crack GPU's
