2021-08-02drm: Define DRM_FORMAT_MAX_PLANESThomas Zimmermann1-4/+4
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 <drm/drm_fourcc.h> for DRM_FORMAT_MAX_PLANES Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20210730183511.20080-2-tzimmermann@suse.de

2016-11-17drm: Nuke modifier[1-3]Ville Syrjälä1-2/+2
It has been suggested that having per-plane modifiers is making life more difficult for userspace, so let's just retire modifier[1-3] and use modifier[0] to apply to the entire framebuffer. Obviosuly this means that if individual planes need different tiling layouts and whatnot we will need a new modifier for each combination of planes with different tiling layouts. For a bit of extra backwards compatilbilty the kernel will allow non-zero modifier[1+] but it require that they will match modifier[0]. This in case there's existing userspace out there that sets modifier[1+] to something non-zero with planar formats. Mostly a cocci job, with a bit of manual stuff mixed in. @@ struct drm_framebuffer *fb; expression E; @@ - fb->modifier[E] + fb->modifier @@ struct drm_framebuffer fb; expression E; @@ - fb.modifier[E] + fb.modifier Cc: Kristian Høgsberg <hoegsberg@gmail.com> Cc: Ben Widawsky <benjamin.widawsky@intel.com> Cc: Rob Clark <robdclark@gmail.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Tomeu Vizoso <tomeu@tomeuvizoso.net> Cc: dczaplejewicz@collabora.co.uk Suggested-by: Kristian Høgsberg <hoegsberg@gmail.com> Acked-by: Ben Widawsky <ben@bwidawsk.net> Acked-by: Daniel Stone <daniels@collabora.com> Acked-by: Rob Clark <robdclark@gmail.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1479295996-26246-1-git-send-email-ville.syrjala@linux.intel.com
2016-09-19drm: Move a few macros away from drm_crtc.hDaniel Vetter1-0/+17
Now that there's less stuff in there I noticed that I overlooked them. Sprinkle some docs over them while at it.

2016-08-29drm: Extract drm_mode_object.[hc]Daniel Vetter1-1/+1
Just for the struct drm_mode_object base class. The header file was already partially extracted to help untangle the include loops. v2: - Also move the generic get/set property ioctls. At first this seemed like a bad idea since it requires making drm_mode_crtc_set_obj_prop non-static. But eventually that will get split away too (like the connector version already is) for both crtc and planes. Hence I reconsidered. - drm_mode_object.[hc] instead of drm_modeset.[hc], which requires renaming the drm_modeset.h header I already started building up. This is more consistent (matches the name of the main structure), and I want to be able to use drm_modeset.[hc] for the basic modeset init/cleanup functionality like drm_mode_config_init.

- Move the intro section into a DOC comment, and update it slightly. - kernel-doc for struct drm_framebuffer! v2: - Copypaste fail (Sean). - Explain the linear @offsets clearer (Ville).

2016-08-16drm: Extract drm_framebuffer.[hc]Daniel Vetter1-0/+170
Also start with drm_modeset.h with the core bits, since we need to untangle this mess somehow. That allows us to move the drm_modes.h include to the right spot, except for the temporary connector status enum. That will get fixed as soon as drm_connector.h exists. v2: Rebase. v3: Move drm_crtc_force_disable_all back again, that wasn't meant to be moved (Sean). v4: Rebase.
