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

Subject: [Qemu-devel] [PATCH v3 0/2] Virtio GPU for S390
Date: Fri, 15 Sep 2017 10:40:30 -0400

These patches wire up the virtio-gpu device for CCW bus for

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.

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
