Is it possible that it'll just= work > if one adds the GPU to the igd_devices list in usr.sbin/bhyve/amd64= /pci_gvt-d.c? I don't have that hardware, so I can't test and work on it. Adding it to the list of igd_devices won't work because it then tries to apply igd related quirks. Those quirks are highly platform dependend and I doubt that those a= re required for dedicated GPUs because they have to work platform independend.= It would be worth trying what happens when disabling those quirks and simply passing through the GPU. So maybe someone can try to always return ENXIO on gvt_d_probe: static int gvt_d_probe(struct pci_devinst *const pi) { return (ENXIO); } --=20 You are receiving this mail because: You are the assignee for the bug.=
