5164f7e7ff8ec7d41065d3862630c2ba09854328 - drm: Rename struct drm_atomic_state to drm_atomic_commit

Mon, 27 Apr 2026 09:02:57 +0200

drm: Rename struct drm_atomic_state to drm_atomic_commitThe KMS framework uses two slightly different definitions for the stateconcept. For a given object (plane, CRTC, encoder, etc., sodrm_$OBJECT_state), the state is the entire state of that object.However, at the device level, drm_atomic_state refers to a state updatefor a limited number of objects.Thus, drm_atomic_state isn't the entire device state, but only the fullstate of some objects in that device. This has been an endless source ofconfusion and thus bugs.We can rename the drm_atomic_state structure to drm_atomic_commit tomake it less confusing.This patch was created using:rg -l drm_atomic_state | \ xargs sed -i 's/drm_atomic_state/drm_atomic_commit/g; s/drm_atomic_commit_helper/drm_atomic_state_helper/g'mv drivers/gpu/drm/tests/drm_atomic_state_test.c drivers/gpu/drm/tests/drm_atomic_commit_test.cAcked-by: Simona Vetter Acked-by: Thomas Zimmermann Acked-by: Jani Nikula Reviewed-by: Luca Ceresoli Tested-by: Luca Ceresoli Signed-off-by: Maxime Ripard Signed-off-by: Dave Airlie Link: https://patch.msgid.link/20260427-drm-drm-atomic-update-v4-1-c0e713bfdf25@kernel.org List of files: /linux/drivers/gpu/drm/tests/Makefile

Thu, 05 Feb 2026 23:52:38 +0100

gpu: Move DRM buddy allocator one level up (part one)Move the DRM buddy allocator one level up so that it can be used by GPUdrivers (example, nova-core) that have usecases other than DRM (such asVFIO vGPU support). Modify the API, structures and Kconfigs to use"gpu_buddy" terminology. Adapt the drivers and tests to use the new API.The commit cannot be split due to bisectability, however no functionalchange is intended.

drm/tests: Add a few tests around drm_fixed.hWhile working on the CTM implementation of VKMS I had to ascertainmyself of a few assumptions. One of those is whether drm_fixed.htreats its numbers using signed-magnitude or twos-complement. It istwos-complement.In order to make someone else's day easier I am adding thedrm_test_int2fixp test that validates the above assumption.I am also adding a test for the new sm2fixp function that convertsfrom a signed-magnitude fixed point to the twos-complement fixedpoint.Reviewed-by: Louis Chauvet Signed-off-by: Alex Hung Signed-off-by: Harry Wentland Reviewed-by: Daniel Stone Signed-off-by: Simon Ser Link: https://patch.msgid.link/20251115000237.3561250-22-alex.hung@amd.com List of files: /linux/drivers/gpu/drm/tests/Makefile

drm/modes: Add a function to generate analog display modesMultiple drivers (meson, vc4, sun4i) define analog TV 525-lines and625-lines modes in their drivers.Since those modes are fairly standard, and that we'll need to use themin more places in the future, it makes sense to move their definitioninto the core framework.However, analog display usually have fairly loose timings requirements,the only discrete parameters being the total number of lines and pixelclock frequency. Thus, we created a function that will create a displaymode from the standard, the pixel frequency and the active area.Tested-by: Mateusz Kwiatkowski Acked-in-principle-or-something-like-that-by: Daniel Vetter Link: https://lore.kernel.org/r/20220728-rpi-analog-tv-properties-v10-6-256dad125326@cerno.techSigned-off-by: Maxime Ripard List of files: /linux/drivers/gpu/drm/tests/Makefile
