drm: Define DRM_FORMAT_MAX_PLANES

2021-08-02T14:41:20+00:00

DRM uses a magic number of 4 for the maximum number of planes per color
format. Declare this constant via DRM_FORMAT_MAX_PLANES and update the
related code. Some code depends on the length of arrays that are now
declared with DRM_FORMAT_MAX_PLANES. Convert it from '4' to ARRAY_SIZE.

v2:
	* mention usage of ARRAY_SIZE() in the commit message (Maxime)
	* also fix error handling in drm_gem_fb_init_with_funcs()
	  (kernel test robot)
	* include  for DRM_FORMAT_MAX_PLANES

drm/core: Calculate bpp in afbc helper

2020-04-01T12:11:22+00:00

Some drivers (komeda, malidp) don't set anything in cpp. If that is the
case the right value can be inferred from the format. Then the "bpp" member
can be eliminated from struct drm_afbc_framebuffer.

Fix following warnings:
drm_framebuffer.h:342: warning: Function parameter or member 'block_width' not described in 'drm_afbc_framebuffer'
drm_framebuffer.h:342: warning: Function parameter or member 'block_height' not described in 'drm_afbc_framebuffer'

Trivial spelling mistakes.

drm/core: Add drm_afbc_framebuffer and a corresponding helper

2020-03-18T10:22:05+00:00

The new struct contains afbc-specific data.

The new function can be used by drivers which support afbc to complete
the preparation of struct drm_afbc_framebuffer. It must be called after
allocating the said struct and calling drm_gem_fb_init_with_funcs().

drm: Forward-declare struct drm_format_info in drm_framebuffer.h

2019-03-28T04:06:33+00:00

drm_framebuffer.h makes use of a pointer to struct drm_format_info but
doesn't include drm_fourcc.h (neither directly nor indirectly).
Forward-declare the structure.

drm: make drm_framebuffer.h self contained

2019-01-09T21:11:28+00:00

Add forward declaration and pull in include
file to make drm_framebuffer.h self contained.

While add it order include files alphabetically.

The use of TASK_COMM_LEN is the reason for including sched.h.
I could not see any good way to avoid this dependency,
and users of drm_framebuffer.comm already use
TASK_COMM_LEN to check for length etc.

v2:
- Added forward declaration of drm_gem_object (Noralf)
- Added ack from Noralf

There are no more places where this (deprecated) function is being used

This is is very useful to finding sources of leaked framebufers.
The fbcon fb is annotated with [fbcon], to give it a better name
