drm/virtio: virtio_{blah} --> virtio_gpu_{blah}

2020-12-02T10:48:14+00:00

virtio_gpu typically uses the prefix virtio_gpu, but there are a few places where the virtio prefix is used. Modify this for consistency. v3: add r-b tags Signed-off-by: Gurchetan Singh Reviewed-by: Anthoine Bourgeois Link: http://patchwork.freedesktop.org/patch/msgid/20201201021623.619-1-gurchetansingh@chromium.org Signed-off-by: Gerd Hoffmann

drm/virtio: rename sync_seq and last_seq

2020-11-20T09:44:41+00:00

To be clearer about our intentions to associate sequence numbers and fence IDs, let's rename these variables.

drm/virtio: implement blob resources: implement vram object

2020-09-29T09:23:33+00:00

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).

drm/virtio: implement blob resources: probe for host visible region

2020-09-29T09:23:22+00:00

The availability of the host visible region means host 3D allocations can be directly mapped in the guest.

drm: convert .debugfs_init() hook to return void.

2020-03-18T16:53:28+00:00

As a result of commit 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail) and changes to various debugfs functions in drm/core and across various drivers, there is no need for the drm_driver.debugfs_init() hook to have a return value. Therefore, declare it as void. This also includes refactoring all users of the .debugfs_init() hook to return void across the subsystem. v2: include changes to the hook and drivers that use it in one patch to prevent driver breakage and enable individual successful compilation of this change.

drm/virtio: fix ring free check

2020-02-07T08:33:55+00:00

If the virtio device supports indirect ring descriptors we need only one ring entry for the whole command. Take that into account when checking whenever the virtqueue has enough free entries for our command.

This file prints which features the virtio-gpu device has. Also add "virtio-gpu-" prefix to the existing fence file, to make clear this is a driver-specific debugfs file.
