2020-05-08T05:04:25+00:00

A few minor fixes for an ordering issue in virtio, an (old) gcc warning
in sun4i, a probe issue in ingenic-drm and a regression in the HDCP
support.

drm/virtio: create context before RESOURCE_CREATE_2D in 3D mode

2020-05-04T07:53:37+00:00

If 3D is enabled, but userspace requests a dumb buffer, we will
call CTX_ATTACH_RESOURCE before actually creating the context.

drm/virtio: delete notify after virtio_gpu_cmd_context_create

The first 3D ioctl will take care of notification.

drm/virtio: enqueue virtio_gpu_create_context after the first 3D ioctl

2020-02-25T08:48:42+00:00

For old userspace, initialization will still be implicit.

For backwards compatibility, enqueue virtio_gpu_cmd_context_create after
the first 3D ioctl.

v3: staticify virtio_gpu_create_context
    remove notify to batch vm-exit
v6: Remove nested 3D checks (emil.velikov):
      - unify 3D check in resource create
v7: Remove check when getting capabilities

2020-02-25T08:48:42+00:00

Use an boolean variable to track whether a context has been
initiated.

drm/virtio: factor out context create hypercall

2020-02-25T08:48:41+00:00

We currently create an OpenGL context when opening the DRM fd
if 3D is available.

We may need other context types (VK,..) in the future, and the plan
is to have explicit initialization for that.

For explicit initialization to work, we need to factor out
virtio_gpu_create_context from driver initialization.

v2: Move context handle initialization too (olv)
v6: Remove redundant 3D check (emil.velikov)
