These patches wire up the virtio-gpu device for CCW bus for S390.
For the S390 architecture which does not natively support any
graphics device, virtio gpu in 2D mode could be used to emulate a
simple graphics card and use VNC as the display.
eg: qemu-system-s390x ... -device virtio-gpu-ccw,devno=fe.0.0101
-vnc host_ip_addr:5900
Note, to actually see any display content the guest kernel needs to
support DRM layer, Virtio GPU driver, the Virtual Terminal layer
etc.
Do you have a list of CONFIG options that need to be enabled there?
Are there also any patches to the guest kernel driver required? Or
did that work out of the box once you've enabled the right CONFIG
options?
I would appreciate any feedback on these patches, specially the
first patch.
Patches look good to me, but I'm not at all familiar with the
virtio-gpu code, so that likely does not count...
Anyway, thanks a lot for tackling this! It's pretty cool to finally
have a graphics card on s390x, too :-)
