drm/virtio: move byteorder handling into virtio_gpu_cmd_transfer_to_host_2d function

2019-10-22T09:34:03+00:00

Be consistent with the rest of the code base.

drm/virtio: add worker for object release

2019-09-04T04:54:12+00:00

Move object release into a separate worker.  Releasing objects requires
sending commands to the host.  Doing that in the dequeue worker will
cause deadlocks in case the command queue gets filled up, because the
dequeue worker is also the one which will free up slots in the command
queue.

drm/virtio: remove virtio_gpu_alloc_object

2019-09-04T04:54:11+00:00

Thin wrapper around virtio_gpu_object_create(),
but calling that directly works equally well.

drm/virtio: switch from ttm to gem shmem helpers

2019-09-04T04:54:11+00:00

virtio-gpu basically needs a sg_table for the bo, to tell the host where
the backing pages for the object are.  So the gem shmem helpers are a
perfect fit.  Some drm_gem_object_funcs need thin wrappers to update the
host state, but otherwise the helpers handle everything just fine.

Once the fencing was sorted the switch was surprisingly easy and for the
most part just removing the ttm code.

v4: fix drm_gem_object_funcs name.
