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.

drm/atomic: Remove state argument to drm_atomic_private_obj_init

2026-03-20T09:03:11+00:00

Now that all drm_private_objs users have been converted to use atomic_create_state instead of the old ad-hoc initialization, we can remove the state parameter from drm_private_obj_init and the fallback code.

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/ingenic: Switch private_obj initialization to atomic_create_state

2026-02-10T09:07:05+00:00

The ingenic driver relies on two drm_private_objs, that are initialized by allocating and initializing a state, and then passing it to drm_private_obj_init. Since we're gradually moving away from that pattern to the more established one relying on a atomic_create_state implementation, let's migrate this instance to the new pattern.

drm/ingenic: crtc: Switch to ingenic_drm_get_new_priv_state()

2025-10-06T11:59:22+00:00

The ingenic CRTC atomic_enable() implementation will indirectly call drm_atomic_get_private_obj_state() through ingenic_drm_get_priv_state(). drm_atomic_get_private_obj_state() will either return the new state for the object in the global state if it exists, or will allocate a new one and add it to the global state. atomic_enable() however isn't allowed to modify the global state. So what the implementation should use is the drm_atomic_get_new_private_obj_state() helper to get the new state for the CRTC, without performing an extra allocation. We still need to make sure the private state will be part of the global state by the time atomic_enable runs, so we still need to call ingenic_drm_get_priv_state() in atomic_check. We can then call ingenic_drm_get_new_priv_state() in atomic_enable, which is a wrapper around drm_atomic_get_new_private_obj_state().

drm/ingenic: Switch to drm_atomic_get_new_crtc_state()

2025-10-06T11:59:13+00:00

The ingenic 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.
