drm/plane-helper: Provide DRM_PLANE_NON_ATOMIC_FUNCS initializer macro

2022-09-20T07:42:31+00:00

Provide DRM_PLANE_NON_ATOMIC_FUNCS, which initializes plane functions
of non-atomic drivers to default values. The macro is not supposed to
be used in new code, but helps with documenting and finding existing
users.

drm/plane: Allocate planes with drm_universal_plane_alloc()

2022-09-20T07:41:06+00:00

Provide drm_univeral_plane_alloc() to allocate and initialize a
plane. Code for non-atomic drivers uses this pattern. Convert them to
the new function. The modeset helpers contain a quirk for handling their
color formats differently. Set the flag outside plane allocation.

The new function is already deprecated to some extend. Drivers should
rather use drmm_univeral_plane_alloc() or drm_universal_plane_init().

v2:
	* kerneldoc fixes (Javier)
	* grammar fixes in commit message

drm/plane: Remove drm_plane_init()

2022-09-20T07:37:12+00:00

Open-code drm_plane_init() and remove the function from DRM. The
implementation of drm_plane_init() is a simple wrapper around a call
to drm_universal_plane_init(), so drivers can just use that instead.

drm/plane-helper: Export individual helpers

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

Export the individual plane helpers that make up the plane functions and
align the naming with other helpers. The plane helpers are for non-atomic
modesetting and exporting them will simplify a later conversion of drivers
to atomic modesetting.

With struct drm_plane_funcs removed from drm_plane_helper.h, also remove
the include statements. It only needs linux/types.h for uint32_t and a
number of forward declarations.

drm: Drop drm_framebuffer.h from drm_crtc.h

2022-06-20T20:53:55+00:00

drm_crtc.h has no need for drm_frambuffer.h, so don't include it.
Avoids useless rebuilds of the entire universe when
touching drm_framebuffer.h.

Quite a few placs do currently depend on drm_framebuffer.h without
actually including it directly. All of those need to be fixed
up.

v2: Fix up msm some more

drm: prepare for drmP.h removal from drm_modeset_helper.h

2019-02-07T20:48:28+00:00

The use of drmP.h is discouraged and removal of it from
drm_modeset_helper.h caused drm/ to fail to build.

This patch introduce the necessary fixes to prepare for the
drmP.h removal from drm_modeset_helper.h.

Build tested on x86, arm, alpha, ia64 allmodconfig/allyesconfig.

drm: Split out drm_probe_helper.h

2019-01-24T12:20:42+00:00

Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.

To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.

v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.

v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.

This will also conflict with ongoing drmP.h cleanup by others I
expect.

v3: Rebase on top of atomic bochs.

v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
  other places (all suggested from Laurent adopted unchanged).
- sort alphabetically

v5: Actually try to sort them, and while at it, sort all the ones I
touch.

v6: Rebase onto i915 changes.

v7: Rebase once more.

Well except the destroy helper, which isn't really a primary helper
but generally useful, if mislabelled.

primarmy plane helpers, and put them into the kerneldoc for

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)
