drm/virtio: simplify the return expression

drm/virtio: support mapping exported vram

2021-08-16T12:09:40+00:00

Implement virtgpu specific map_dma_buf callback to support mapping exported vram object dma-bufs. The dma-buf callback is used directly, as vram objects don't have backing pages and thus can't implement the drm_gem_object_funcs.get_sg_table callback.

drm/virtio: set non-cross device blob uuid_state

2021-08-12T12:58:31+00:00

Blob resources without the cross device flag don't have a uuid to share with other virtio devices. When exporting such blobs, set uuid_state to STATE_ERR so that virtgpu_virtio_get_uuid doesn't hang.

drm/virtio: implement blob resources: refactor UUID code somewhat

2020-09-29T09:23:45+00:00

For upcoming blob resources, userspace can specify that the resource will be used for cross-device sharing. This is mainly for exportable blobs that will only shared with the virtgpu display but not across devices.

drm/virtio: Support virtgpu exported resources

2020-08-18T08:01:54+00:00

Add support for UUID-based resource sharing mechanism to virtgpu. This implements the new virtgpu commands and hooks them up to dma-buf's get_uuid callback.

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.
