Cover letter [Qemu-devel] [PATCH v3 0/2] Virtio GPU for S390

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
Farhan
