Hello Gerd,

I compiled a new kernel with the latest DRM misc updates today. The patch is
included in these updates.

This kernel works with the VirtIO-GPU in a virtual e5500 QEMU/KVM HV machine
on my X5000.

Unfortunately I can only use the VirtIO-GPU (Monitor: Red Hat, Inc. 8") with
a resolution of 640x480. If I set a higher resolution then the guest
disables the monitor.
I can use higher resolutions with the stable kernel 5.8 and the VirtIO-GPU.

Please check the latest DRM updates.

(tests & reviews & acks are welcome)

Hello Gerd,

I compiled a new RC1 with our patches today. With these patches, the VirtIO-GPU works without any problems. I can use higher resolutions again.

Screenshot of the RC1-3 with the VirtIO-GPU in a virtual e5500 QEMU/KVM HV machine on my X5000: https://i.pinimg.com/originals/4f/b0/14/4fb01476edd7abe6be1e1203a8e7e152.png

Thanks a lot for your help!

Cheers,
Christian
