drm/tests: hdmi: check the infoframes behaviour

2026-01-19T11:10:35+00:00

Verify the InfoFrames behaviour. Check that reporting InfoFrame as unsupported doesn't result in a commit error. Also check that HDR and Audio InfoFrames are not triggered if corresponding features are not enabled.

drm/tests: modeset: Fix drm_display_mode memory leak

2025-04-08T15:28:10+00:00

drm_analog_tv_mode() and its variants return a drm_display_mode that needs to be destroyed later one. The drm_test_pick_cmdline_named() test never does however, which leads to a memory leak. Let's make sure it's freed.

drm/client: Constify modes

2025-03-13T16:29:33+00:00

The modes used by the client code live on the connectors' mode lists, which are not owned by the client code, and thus it has no business modifying the modes. Mark the modes const to make that fact abundantly clear. v2: Fix up the kunit test Reviewed-by: Jani Nikula Reviewed-by: Thomas Zimmermann Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20250303093847.7698-1-ville.syrjala@linux.intel.com

drm/tests: client-modeset: Remove call to drm_kunit_helper_free_device()

2023-07-31T12:19:57+00:00

Calling drm_kunit_helper_free_device() to clean up the resources allocated by drm_kunit_helper_alloc_device() is now optional and not needed in most cases. Remove it.

drm/tests: helpers: Allow for a custom device struct to be allocated

2022-12-08T08:56:55+00:00

The current helper to allocate a DRM device doesn't allow for any subclassing by drivers, which is going to be troublesome as we work on getting some kunit testing on atomic modesetting code. Let's use a similar pattern to the other allocation helpers by providing the structure size and offset as arguments.

drm/tests: helpers: Create the device in another function

We'll need in some tests to control when the device needs to be added and removed, so let's split the device creation from the DRM device creation function. Reviewed-by: Maíra Canal Link: https://lore.kernel.org/r/20221123-rpi-kunit-tests-v3-7-4615a663a84a@cerno.tech Signed-off-by: Maxime Ripard

2022-12-08T08:56:55+00:00

The name doesn't really fit the conventions for the other helpers in DRM/KMS, so let's rename it to make it obvious that we allocate a new DRM device. Reviewed-by: Maíra Canal Link: https://lore.kernel.org/r/20221123-rpi-kunit-tests-v3-5-4615a663a84a@cerno.tech Signed-off-by: Maxime Ripard
