drm/armada: Switch to drm_atomic_helper_crtc_create_state

2026-08-31T13:09:22+00:00

The armada crtc implementation uses the deprecated drm_atomic_helper_crtc_reset() as its reset hook. Switch to drm_atomic_helper_crtc_create_state() instead.

drm: Rename struct drm_atomic_state to drm_atomic_commit

2026-05-04T04:05:04+00:00

The KMS framework uses two slightly different definitions for the state concept. For a given object (plane, CRTC, encoder, etc., so drm_$OBJECT_state), the state is the entire state of that object. However, at the device level, drm_atomic_state refers to a state update for a limited number of objects. Thus, drm_atomic_state isn't the entire device state, but only the full state of some objects in that device. This has been an endless source of confusion and thus bugs. We can rename the drm_atomic_state structure to drm_atomic_commit to make it less confusing.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

drm/fb-helper: Allocate and release fb_info in single place

2025-11-25T10:02:43+00:00

Move the calls to drm_fb_helper_alloc_info() from drivers into a single place in fbdev helpers. Allocates struct fb_info for a new framebuffer device. Then call drm_fb_helper_single_fb_probe() to create an fbdev screen buffer. Also release the instance on errors by calling drm_fb_helper_release_info(). Simplifies the code and fixes the error cleanup for some of the drivers. Regular release of the struct fb_info instance still happens in drm_fb_helper_fini() as before. v2: - remove error rollback in driver implementations (kernel test robot) - initialize info in TTM implementation (kernel test robot) Signed-off-by: Thomas Zimmermann Acked-by: Christian König # radeon Acked-by: Dmitry Baryshkov # msm Acked-by: Javier Martinez Canillas Link: https://patch.msgid.link/20251027081245.80262-1-tzimmermann@suse.de

drm: include drm_print.h where needed

2025-10-31T08:34:52+00:00

There are a gazillion files that depend on drm_print.h being indirectly included via drm_buddy.h, drm_mm.h, or ttm/ttm_resource.h. In preparation for removing those includes, explicitly include drm_print.h where needed.

drm/client: Add client free callback to unprepare fb_helper

2025-10-24T06:44:10+00:00

Add free callback to struct drm_client_funcs. Invoke function to free the client memory as part of the release process. Implement free for fbdev emulation. Fbdev emulation allocates and prepares client memory in drm_fbdev_client_setup(). The release happens in fb_destroy from struct fb_ops. Multiple implementations of this callback exist in the various drivers that provide an fbdev implementation. Each of them needs to follow the implementation details of the fbdev setup code. Adding a free callback for the client puts the unprepare and release of the fbdev client in a single place.

drm/armada: Switch to drm_atomic_get_new_crtc_state()

2025-10-06T11:59:10+00:00

The armada atomic_check implementation uses the deprecated drm_atomic_get_existing_crtc_state() helper. This hook is called as part of the global atomic_check, thus before the states are swapped. The existing state thus points to the new state, and we can use drm_atomic_get_new_crtc_state() instead.

drm/armada: Drop always true condition in atomic_check

2025-10-06T11:59:10+00:00

The drm_atomic_state pointer passed to atomic_check is always valid, so checking if it's NULL or not is pointless. Remove the check.

drm/armada: Pass along the format info from .fb_create() to drm_helper_mode_fill_fb_struct()

Plumb the format info from .fb_create() all the way to drm_helper_mode_fill_fb_struct() to avoid the redundant lookup. For the fbdev case a manual drm_get_format_info() lookup is needed.
