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.
I would appreciate any feedback on these patches, specially the
first patch.
ChangeLog
--------
v1 -> v2
- remove error_propagate (patch 2)
- Add byteswap functions (patch 1)
- Handle endian conversion for virtio_gpu_ctrl_response (patch 1)
v2 -> v3
- updated patch 1 based on Gerd's feedback
- rename bswap functions (patch 1)
- use in-place swapping functions (patch 1)
- Handle endian conversion for cursor update (patch 1)
Thank you
