It's was indeed unclear to me how to test the > MMIO GPU, but yours variant with microvm works! I was looking for trying > aarch64 in the past, but it also was unclear how to do it since there is > no DT support for the VirtIO-GPU, AFAICS. aarch64 uses acpi by default (can be disabled via 'qemu -no-acpi'). Not fully sure about arm(v7). Even with DT it should work because DT only describes the virtio-mmio 'slots', not the actual virtio devices. > There is no virgl support because it's a virtio-gpu-device and not > virtio-gpu-device-gl that is PCI-only in Qemu. Hence everything seems good. It's named 'virtio-gpu-gl-device' take care, Gerd
