drm/vkms: Add tests for CTM handling

2025-11-26T22:03:33+00:00

A whole slew of tests for CTM handling that greatly helped in debugging the CTM code. The extent of tests might seem a bit silly but they're fast and might someday help save someone else's day when debugging this.

drm/vkms: Add kunit tests for linear and sRGB LUTs

Two tests are added to VKMS LUT handling: - linear - inv_srgb 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/20251115000237.3561250-18-alex.hung@amd.com

drm/vkms: Add config for default plane pipeline

2025-11-26T22:03:33+00:00

With the introduction of color pipeline in VKMS, the default device may have planes with color pipelines. To avoid breaking existing uAPI, create a kernel argument to disable them by default and a vkms_config field to configure the plane. This field is not definitive and will be replaced once the uAPI will be able to configure color pipelines. For now devices created with ConfigFS will not have any color pipeline so we can decide later how the uAPI will look like.

drm/vkms: Add kunit tests for VKMS LUT handling

2025-11-26T21:17:45+00:00

Debugging LUT math is much easier when we can unit test it.

drm/vkms: Allow to configure connector status

2025-10-22T11:19:26+00:00

Allow to store the connector status in vkms_config_connector and add a getter and a setter functions as well a KUnit test. This change only adds the configuration, the connector status is not used yet.

drm/vkms: Change YUV helpers to support u16 inputs for conversion

Some YUV format uses 16 bit values, so change the helper function for conversion to support those new formats. Reviewed-by: Maíra Canal Acked-by: Daniel Stone Link: https://lore.kernel.org/r/20250703-b4-new-color-formats-v7-6-15fd8fd2e15c@bootlin.com Signed-off-by: Louis Chauvet

drm/vkms: Assert if vkms_config_create_*() fails

Check that the value returned by the vkms_config_create_*() functions is valid. Otherwise, assert and finish the KUnit test.

drm/vkms: Compile all tests with CONFIG_DRM_VKMS_KUNIT_TEST

2025-06-13T17:11:39+00:00

The Kconfig option `CONFIG_DRM_VKMS_KUNIT_TESTS` does not exist. However, the VKMS format tests use such an option for compilation, meaning that they are not compiled at all. Use the Kconfig option `CONFIG_DRM_VKMS_KUNIT_TEST` to compile all VKMS KUnit tests.

drm/vkms: Create KUnit tests for YUV conversions

2025-05-28T14:19:14+00:00

Create KUnit tests to test the conversion between YUV and RGB. Test each conversion and range combination with some common colors. The code used to compute the expected result can be found in comment. [Louis Chauvet: - fix minor formating issues (whitespace, double line) - change expected alpha from 0x0000 to 0xffff - adapt to the new get_conversion_matrix usage - apply the changes from Arthur - move struct pixel_yuv_u8 to the test itself] Signed-off-by: Arthur Grillo Acked-by: Pekka Paalanen Acked-by: Maxime Ripard Link: https://lore.kernel.org/r/20250415-yuv-v18-6-f2918f71ec4b@bootlin.com Signed-off-by: Louis Chauvet

drm/vkms: Allow to attach connectors and encoders

Add a list of possible encoders to the connector configuration and helpers to attach and detach them. Now that the default configuration has its connector and encoder correctly, configure the output following the configuration.
