drm: rcar-du: Fix crash when no CMM is available

2026-04-23T12:53:46+00:00

Commit 3bce3fdd1ff2 ("drm: rcar-du: Don't leak device_link to CMM") refactored CMM handling, and introduced an incorrect test for CMM availability. When no CMM is present, the rcrtc->cmm field is NULL, testing rcrtc->cmm->dev causes a NULL pointer dereference. This slipped through testing as all tests were run with the CMM present. Fix this issue by correctly testing for rcrtc->cmm.

drm/amd/display: Disable 10-bit truncation and dithering on DCE 6.x

2026-04-21T21:03:33+00:00

DCE 6.x doesn't support 10-bit truncation and 10-bit dithering because the following fields are 1-bit only: FMT_TEMPORAL_DITHER_DEPTH FMT_SPATIAL_DITHER_DEPTH FMT_TRUNCATE_DEPTH Programming these fields to "2" will program them as if the dithering option was 6-bit, resulting in sub-par picture quality and an ugly "color banding" effect. Note that a recent commit changed the default 10-bit dithering option to DITHER_OPTION_SPATIAL10 which improves the picture quality because it happens to look better, but is still not actually supported by DCE 6.x versions. When the color depth is 10-bit or more, just disable any kind of dithering options on DCE 6.x.
