Wei Yongjun a9853117d8 drm/virtio: Fix non static symbol warning
Fixes the following sparse warning:

drivers/gpu/drm/virtio/virtgpu_display.c:349:37: warning:
  symbol 'virtio_mode_config_helpers' was not declared. Should it be static?

Markus Elfring 5345a5ab51 drm/virtgpu: Delete unnecessary checks before drm_gem_object_unreference_unlocked()
The drm_gem_object_unreference_unlocked() function tests whether
its argument is NULL and then returns immediately.
Thus the test around the calls is not needed.

This issue was detected by using the Coccinelle software.

Daniel Vetter 0d841ac0ec drm/virtio: Don't reinvent a flipping wheel
Now that the core helpers support nonblocking atomic commits there's
no need to invent that wheel separately (instead of fixing the bug in
the atomic implementation of virtio, as it should have been done!).

Boris Brezillon a50dcc5001 drm: virtgpu: Rely on the default ->best_encoder() behavior
The virtgpu output exposes a 1:1 relationship between connectors and
encoders and the driver is relying on the atomic helpers: we can drop
the custom ->best_encoder() implementation and let the core call
drm_atomic_helper_best_encoder() for us.

Daniel Vetter 5e84c2690b drm/atomic-helper: Massage swap_state signature somewhat
- dev is redundant, we have state->atomic
- add stall parameter, which must be set when swapping needs to stall
  for preceeding commits to stop looking at ->state pointers. Currently
  all drivers need this to be, just prep work for a glorious future.

Ville Syrjälä 6af3e65612 drm: Drop drm_helper_probe_single_connector_modes_nomerge()
Now that the mode type bit merge logic is fixed to only merge
between new probed modes, hopefully we can eliminat the special
case for qxl and virtio. That is make the merge the mode type
bits from all matching new probed modes, just like every other
driver.

qxl and virtio got excluded from the merging in
commit 3fbd6439e4 ("drm: copy mode type in drm_mode_connector_list_update()")
commit abce1ec9b0 ("Revert "drm: copy mode type in drm_mode_connector_list_update()"")

Dave Airlie dc5698e80c Add virtio gpu driver.
This patch adds a kms driver for the virtio gpu.  The xorg modesetting
driver can handle the device just fine, the framebuffer for fbcon is
there too.

Qemu patches for the host side are under review currently.

The pci version of the device comes in two variants: with and without
vga compatibility.  The former has a extra memory bar for the vga
framebuffer, the later is a pure virtio device.  The only concern for
this driver is that in the virtio-vga case we have to kick out the
firmware framebuffer.

Initial revision has only 2d support, 3d (virgl) support requires
some more work on the qemu side and will be added later.
