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]

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.

drm/vkms: Add a validation function for VKMS configuration

2025-03-07T09:58:23+00:00

As the configuration will be used by userspace, add a validator to avoid
creating a broken DRM device.

For the moment, the function always returns true, but rules will be
added in future patches.
