Hi Dave, Sima, this is the weekly PR for drm-misc-next. Besides the usual fixes, it adds support for CRTC background colors. There are some changes that affect the kernel's math helpers.
Best regards Thomas drm-misc-next-2026-03-20: drm-misc-next for v7.1: UAPI Changes: math: - provide __KERNEL_DIV_ROUND_CLOSEST() in UAPI mode: - provide DRM_ARGB_GET*() macros for reading color components Cross-subsystem Changes: math: - implement DIV_ROUND_CLOSEST() with __KERNEL_DIV_ROUND_CLOSEST() Core Changes: atomic: - fix handling of colorop state in atomic updates - provide CRTC background color ttm: - improve tests and doumentation Driver Changes: amdxdna: - allow forcing DMA through IOMMU IOVA - improve debugging bridge: - Support Lontium LT8713SX DP MST bridge plus DT bindings imx: - support planes behind the primary plane - fix bus-format selection ivpu: - perform engine reset on TDR error panel: - novatek-nt36672a: Use mipi_dsi_*_multi() functions - panel-edp: Support BOE NV153WUM-N42, CMN N153JCA-ELK, CSW MNF307QS3-2 renesas: - rz-du: clean up rockchip: - support CRTC background color sun4i: - fix leak in init code - clean up tildc - clean up v3d: - improve handling of struct v3d_stats - improve error handling - clean up vkms: - support CRTC background color The following changes since commit f08ceb71c5a5615577e7c841e1e00a89f495ab51: Merge
