drm: Allow drivers to indicate the damage helpers to ignore damage clips

2024-02-01T00:19:08+00:00

commit 35ed38d58257336c1df26b14fd5110b026e2adde upstream. It allows drivers to set a struct drm_plane_state .ignore_damage_clips in their plane's .atomic_check callback, as an indication to damage helpers such as drm_atomic_helper_damage_iter_init() that the damage clips should be ignored. To be used by drivers that do per-buffer (e.g: virtio-gpu) uploads (rather than per-plane uploads), since these type of drivers need to handle buffer damages instead of frame damages. That way, these drivers could force a full plane update if the framebuffer attached to a plane's state has changed since the last update (page-flip).

drm/simple-kms: Remove drm_gem_simple_display_pipe_prepare_fb()

2022-12-05T12:35:37+00:00

The helper drm_gem_simple_display_pipe_prepare_fb() is simple-KMS' default implementation for prepare_fb. Remove the call from drivers that set it explicitly. Then inline the helper into the only caller within simple-kms helpers. No functional changes. Simple-KMS drivers that implement the prepare_fb callback should call drm_gem_plane_helper_prepare_fb() directly. v2: * fix typo in commit message Signed-off-by: Thomas Zimmermann Reviewed-by: Noralf Trønnes Link: https://patchwork.freedesktop.org/patch/msgid/20221202125644.7917-2-tzimmermann@suse.de

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 Signed-off-by: Thomas Zimmermann Reviewed-by: Javier Martinez Canillas Reviewed-by: Lyude Paul # nouveau Link: https://patchwork.freedesktop.org/patch/msgid/20220909105947.6487-3-tzimmermann@suse.de

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: handle kernel fences in drm_gem_plane_helper_prepare_fb v2

2022-05-02T07:01:51+00:00

drm_gem_plane_helper_prepare_fb() was using drm_atomic_set_fence_for_plane() which ignores all implicit fences when an explicit fence is already set. That's rather unfortunate when the fb still has a kernel fence we need to wait for to avoid presenting garbage on the screen. So instead update the fence in the plane state directly. While at it also take care of all potential GEM objects and not just the first one. Also remove the now unused drm_atomic_set_fence_for_plane() function, new drivers should probably use the atomic helpers directly. v2: improve kerneldoc, use local variable and num_planes, WARN_ON_ONCE on missing planes.

drm/plane: Move drm_plane_enable_fb_damage_clips into core

2021-07-27T10:21:22+00:00

We're trying to have a fairly strict split between core functionality that defines the uapi, including the docs, and the helper functions to implement it. Move drm_plane_enable_fb_damage_clips and associated kerneldoc into drm_plane from drm_damage_helper.c to fix this.
