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

2025-09-05T17:57:25+00:00

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

2025-09-05T17:05:37+00:00

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

2025-03-07T09:58:28+00:00

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.

drm/vkms: Allow to configure multiple connectors

2025-03-07T09:58:28+00:00

Add a list of connectors to vkms_config and helper functions to add and remove as many connectors as wanted. For backwards compatibility, add one enabled connector to the default configuration. A future patch will allow to attach connectors and encoders, but for the moment there are no changes in the way the output is configured.
