drm/fb-helper: Remove unnecessary include statements

2022-11-05T16:12:04+00:00

Remove include statements for  where it is not
required (i.e., most of them). In a few places include other header
files that are required by the source code.

v3:
	* fix amdgpu include statements
	* fix rockchip include statements

drm/fb-helper: Move generic fbdev emulation into separate source file

2022-11-05T16:12:04+00:00

Move the generic fbdev implementation into its own source and header
file. Adapt drivers. No functional changes, but some of the internal
helpers have been renamed to fit into the drm_fbdev_ naming scheme.

v3:
	* rename drm_fbdev.{c,h} to drm_fbdev_generic.{c,h}
	* rebase onto vmwgfx changes
	* rebase onto xlnx changes
	* fix include statements in amdgpu

virtio-gpu: fix shift wrapping bug in virtio_gpu_fence_event_create()

2022-09-23T11:16:37+00:00

The ->ring_idx_mask variable is a u64 so static checkers, Smatch in
this case, complain if the BIT() is not also a u64.

drivers/gpu/drm/virtio/virtgpu_ioctl.c:50 virtio_gpu_fence_event_create()
warn: should '(1 << ring_idx)' be a 64 bit type?

drm/virtio: set fb_modifiers_not_supported

2022-09-07T10:13:22+00:00

Without this, the drm core advertises LINEAR modifier which is
incorrect.

Also userspace virgl does not support modifiers.  For example, it causes
chrome on ozone/drm to fail with "Failed to create scanout buffer".

drm/virtio: Fix same-context optimization

2022-08-25T09:56:22+00:00

When VIRTGPU_EXECBUF_RING_IDX is used, we should be considering the
timeline that the EB if running on rather than the global driver fence
context.

drm/virtio: remove drm_plane_cleanup() destroy hook

2022-08-19T14:00:15+00:00

drmm_universal_plane_alloc() already registers drm_plane_cleanup() as
managed release action via drmm_add_action_or_reset(). Hence,
drm_plane_cleanup() should not be set as drm_plane_funcs.destroy hook.

drm/atomic-helper: Remove _HELPER_ infix from DRM_PLANE_HELPER_NO_SCALING

2022-07-26T16:42:00+00:00

Rename DRM_PLANE_HELPER_NO_SCALING to DRM_PLANE_NO_SCALING. The constant
is not really a helper, but rather a characteristic of the plane itself.

drm/atomic-helper: Move DRM_PLANE_HELPER_NO_SCALING to atomic helpers

2022-07-26T16:41:56+00:00

The macro DRM_PLANE_HELPER_NO_SCALING is only useful with the interfaces
in drm_atomic_helper.h, but defined in drm_plane_helper.h. So half of
DRM includes the latter header file for using this macro. Move the macro
and remove the include statements.
