Revert "drm: Introduce pixel_source DRM plane property"

2023-12-04T19:33:10+00:00

This reverts commit e50e5fed41c7eed2db4119645bf3480ec43fec11. Although the Solid Fill planes patchset got all reviews and acknowledgements, it doesn't fulfill requirements for the new uABI. It has neither corresponding open-source userspace implementation nor the IGT tests coverage. Reverting this patchset until userspace obligations are fulfilled.

drm: Add solid fill pixel source

2023-12-01T23:56:50+00:00

Add "SOLID_FILL" as a valid pixel source. If the pixel_source property is set to "SOLID_FILL", it will display data from the drm_plane "solid_fill" blob property.

drm: Introduce solid fill DRM plane property

2023-12-01T23:56:48+00:00

Document and add support for solid_fill property to drm_plane. In addition, add support for setting and getting the values for solid_fill. To enable solid fill planes, userspace must assign a property blob to the "solid_fill" plane property containing the following information: struct drm_mode_solid_fill { u32 r, g, b, pad; }; Acked-by: Harry Wentland Acked-by: Sebastian Wick Signed-off-by: Jessica Zhang Reviewed-by: Dmitry Baryshkov Signed-off-by: Dmitry Baryshkov Link: https://patchwork.freedesktop.org/patch/msgid/20231027-solid-fill-v7-2-780188bfa7b2@quicinc.com

drm: Introduce pixel_source DRM plane property

2023-12-01T23:56:46+00:00

Add support for pixel_source property to drm_plane and related documentation. In addition, force pixel_source to DRM_PLANE_PIXEL_SOURCE_FB in DRM_IOCTL_MODE_SETPLANE as to not break legacy userspace. This enum property will allow user to specify a pixel source for the plane. Possible pixel sources will be defined in the drm_plane_pixel_source enum. Currently, the only pixel sources are DRM_PLANE_PIXEL_SOURCE_FB (the default value) and DRM_PLANE_PIXEL_SOURCE_NONE.
