drm/vkms: Create helper macro for YUV formats

2025-09-05T17:57:26+00:00

The callback functions for line conversion are almost identical for semi-planar formats. The generic READ_LINE_YUV_SEMIPLANAR macro generate all the required boilerplate to process a line from a semi-planar format.

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: Create helpers macro to avoid code duplication in format callbacks

2025-09-05T17:57:16+00:00

The callback functions for line conversion are almost identical for some format. The generic READ_LINE macro generate all the required boilerplate to process a line. Two overrides of this macro have been added to avoid duplication of the same arguments every time.

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

drm/vkms: Add writeback encoders as possible clones

2025-07-31T14:29:59+00:00

Since commit 41b4b11da0215 ("drm: Add valid clones check") setting the `possible_clones` values is a hard requirement for cloning. `vkms` supports cloning for writeback connectors in order to capture CRTC content, however that broke with said commit. Writeback connectors are created on a per-CRTC basis, thus mark every non-writeback connector that is compatible with a given CRTC as possible clone - and vice-versa. Using a default configuration, the corresponding `drm_info` output changes from: ├───Encoders │ ├───Encoder 0 │ │ ├───Object ID: 40 │ │ ├───Type: virtual │ │ ├───CRTCS: {0} │ │ └───Clones: {0} │ └───Encoder 1 │ ├───Object ID: 41 │ ├───Type: virtual │ ├───CRTCS: {0} │ └───Clones: {1} into: ├───Encoders │ ├───Encoder 0 │ │ ├───Object ID: 44 │ │ ├───Type: virtual │ │ ├───CRTCS: {0} │ │ └───Clones: {0, 1} │ └───Encoder 1 │ ├───Object ID: 50 │ ├───Type: virtual │ ├───CRTCS: {0} │ └───Clones: {0, 1} Fixes: dbd9d80c1b2e ("drm/vkms: Add support for writeback") Signed-off-by: Robert Mader Reviewed-by: Louis Chauvet Link: https://lore.kernel.org/r/20250718121442.490634-1-robert.mader@collabora.com [fixed Fixes line and changed to: to into: to avoid checkpatch warnings] Signed-off-by: Louis Chauvet
