I was finally able to boot kernel-latest (running 5.12 now), by hiding the dGPU from the amdgpu module (with "pci-stub.ids=1002:7340"), and installing the linux-firmware package from current 4.1 snapshot.
We can note that this does not give proper GPU support even for the iGPU, as dom0 Xorg still uses LLVMpipe for rendering, but at least we have a display. Occasionally some screen corruption appears as horizontal lines, which go away by temporarily switching to another desktop; also the miniatures in xfce's alt-tab window list often get garbled in a not-unlike way, eg. when a firefox reopens a many-window session, until the window gets fully drawn by alt-tabbing to it once.

Even with 5.12-9 the kernel logs show "AMD IOMMUv2 functionality not available on this system", although lspci does show a 1022:1631 device, which recent pci.ids identify as "Renoir IOMMU". I can see the kernel got some cleanup of drivers/iommu/amd since 5.12, but no commit there advertises support for this hardware. But then, history for this part of the kernel does not appear to show much information about newly-supported hardware, and no pci_device_id list appears there either, so who knows without testing :). Not sure how this information can fit in the HCL :) -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
