drm/virtio: support mapping exported vram

2021-08-16T12:09:40Z

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: fix prime export for vram objects

2021-01-11T07:49:48Z

commit 16845c5d5409 ("drm/virtio: implement blob resources: implement vram object") and commit c6069a02fa55 ("drm/virtgpu: Set PRIME export function in struct drm_gem_object_funcs") landed from different trees, resulting in prime export never working for vram objects.

drm/virtio: implement blob resources: implement vram object

2020-09-29T09:23:33Z

A virtio-gpu vram object is based on range-based allocation. No guest shmemfs backing, so we call drm_gem_private_object_init. This is for host memory without any guest backing (atleast initially).
