drm/vkms: Convert to DRM's vblank timer

2026-06-01T15:50:39+00:00

[ Upstream commit 02e2681ffe1addde1fc8c35d05657b16bfa79613 ] Replace vkms' vblank timer with the DRM implementation. The DRM code is identical in concept, but differs in implementation. Vblank timers are covered in vblank helpers and initializer macros, so remove the corresponding hrtimer in struct vkms_output. The vblank timer calls vkms' custom timeout code via handle_vblank_timeout in struct drm_crtc_helper_funcs.

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.

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

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.
