* drm/virtio: add in/out fence support for explicit synchronizationRobert Foss2018-11-141-1/+1
| | | | | | | | | | | | | | | | | | | | | When the execbuf call receives an in-fence it will get the dma_fence related to that fence fd and wait on it before submitting the draw call. On the out-fence side we get fence returned by the submitted draw call and attach it to a sync_file and send the sync_file fd to userspace. On error -1 is returned to userspace. VIRTGPU_EXECBUF_FENCE_FD_IN & VIRTGPU_EXECBUF_FENCE_FD_OUT are supported at the simultaneously and can be flagged for simultaneously.

* drm/virtio: add uapi for in and out explicit fencesRobert Foss2018-11-141-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | Add a new field called fence_fd that will be used by userspace to send in-fences to the kernel and receive out-fences created by the kernel. This uapi enables virtio to take advantage of explicit synchronization of dma-bufs. There are two new flags: * VIRTGPU_EXECBUF_FENCE_FD_IN to be used when passing an in-fence fd. * VIRTGPU_EXECBUF_FENCE_FD_OUT to be used when requesting an out-fence fd The execbuffer IOCTL is now read-write to allow the userspace to read the out-fence. On error -1 should be returned in the fence_fd field.

* virtio-gpu: fix ioctl and expose the fixed status to userspace.Dave Airlie2018-02-271-0/+1
| | | | | | | | | This exposes to mesa that it can use the fixed ioctl for querying later cap sets, cap set 1 is forever frozen in time.

* drm: fix inclusion of drm.h in virtgpu_drm.hGabriel Laskar2015-12-101-2/+1
| | | | | | | | | | | Using `#include "drm.h"` instead of `#include <drm/drm.h>` allow drm headers to be moved in another directory without changes, like for the libdrm imports.
