drm/virtio: move drm_connector_update_edid_property() call

2019-06-26T09:05:05+00:00

drm_connector_update_edid_property can sleep, we must not
call it while holding a spinlock.  Move the callsite.

drm/virtio: rework resource creation workflow.

2019-03-28T11:11:56+00:00

This patch moves the virtio_gpu_cmd_create_resource() call (which
notifies the host about the new resource created) into the
virtio_gpu_object_create() function.  That way we can call
virtio_gpu_cmd_create_resource() before ttm_bo_init(), so the host
already knows about the object when ttm initializes the object and calls
our driver callbacks.

Specifically the object is already created when the
virtio_gpu_ttm_tt_bind() callback invokes virtio_gpu_object_attach(),
so the extra virtio_gpu_object_attach() calls done after
virtio_gpu_object_create() are not needed any more.

The fence support for the create ioctl becomes a bit more tricky though.
The code moved into virtio_gpu_object_create() too.  We first submit the
(fenced) virtio_gpu_cmd_create_resource() command, then initialize the
ttm object, and finally attach just created object to the fence for the
command in case it didn't finish yet.

drm/virtio: params struct for virtio_gpu_cmd_create_resource_3d()

2019-03-28T11:11:56+00:00

Add 3d resource parameters to virtio_gpu_object_params struct.  With
that in place we can use it for virtio_gpu_cmd_resource_create_3d()
calls.

drm/virtio: params struct for virtio_gpu_cmd_create_resource()

2019-03-28T11:11:56+00:00

Add format, width and height fields to the virtio_gpu_object_params
struct.  With that in place we can use the parameter struct for
virtio_gpu_cmd_create_resource() calls too.

drm/virtio: fence: pass plain pointer

2018-11-29T12:45:07+00:00

Since commit "9fdd90c0f4 drm/virtio: add virtio_gpu_alloc_fence()"
fences are not allocated any more by virtio_gpu_fence_emit().  So there
is no need to pass down a reference to the fence pointer, a plain
pointer is enough now.

Convert virtio_gpu_fence_emit() and callers.

drm/virtio: add virtio_gpu_alloc_fence()

2018-11-14T13:21:01+00:00

Refactor fence creation, add fences to relevant GPU
operations and add cursor helper functions.

This removes the potential for allocation failures from the
cmd_submit and atomic_commit paths.
Now a fence will be allocated first and only after that
will we proceed with the rest of the execution.
