drm/meson: fix vsync buffer update

2018-02-20T09:03:52+00:00

The plane buffer address/stride/height was incorrectly updated in the
plane_atomic_update operation instead of the vsync irq.
This patch delays this operation in the vsync irq along with the
other plane delayed setup.

This issue was masked using legacy framebuffer and X11 modesetting, but
is clearly visible using gbm rendering when buffer is submitted late after
vblank, like using software decoding and OpenGL rendering in Kodi.
With this patch, tearing and other artifacts disappears completely.

drm: Move drm_plane_helper_check_state() into drm_atomic_helper.c

2017-11-20T19:14:22+00:00

drm_plane_helper_check_update() isn't a transitional helper, so let's
rename it to drm_atomic_helper_check_plane_state() and move it into
drm_atomic_helper.c.

drm: Check crtc_state->enable rather than crtc->enabled in drm_plane_helper_check_state()

2017-11-20T18:33:21+00:00

drm_plane_helper_check_state() is supposed to do things the atomic way,
so it should not be inspecting crtc->enabled. Rather we should be
looking at crtc_state->enable.

We have a slight complication due to drm_plane_helper_check_update()
reusing drm_plane_helper_check_state() for non-atomic drivers. Thus
we'll have to pass the crtc_state in manally and construct a fake
crtc_state in drm_plane_helper_check_update().

drm: Nuke drm_atomic_helper_connector_dpms

2017-08-08T12:48:48+00:00

It's dead code, the core handles all this directly now.

The only special case is nouveau and tda988x which used one function
for both legacy modeset code and -nv50 atomic world instead of 2
vtables. But amounts to exactly the same.

v2: Rebase over the panel/brideg refactorings in stm/ltdc.

drm: Plumb modifiers through plane init

2017-08-01T16:50:06+00:00

This is the plumbing for supporting fb modifiers on planes. Modifiers
have already been introduced to some extent, but this series will extend
this to allow querying modifiers per plane. Based on this, the client to
enable optimal modifications for framebuffers.

This patch simply allows the DRM drivers to initialize their list of
supported modifiers upon initializing the plane.

v2: A minor addition from Daniel

v3:
* Updated commit message
* s/INVALID/DRM_FORMAT_MOD_INVALID (Liviu)
* Remove some excess newlines (Liviu)
* Update comment for > 64 modifiers (Liviu)

v4: Minor comment adjustments (Liviu)

v5: Some new platforms added due to rebase

v6: Add some missed plane inits (or maybe they're new - who knows at
this point) (Daniel)
