ttm/pool: port to list_lru. (v2)

2026-04-07T20:52:47+00:00

This is an initial port of the TTM pools for write combined and uncached pages to use the list_lru. This makes the pool's more NUMA aware and avoids needing separate NUMA pools (later commit enables this).

drm/simple-kms: Deprecate simple-kms helpers

2026-03-25T14:05:22+00:00

Deprecate simple-encoder and simple-display-pipe helpers in favor of regular atomic helpers. Remove the related documentation. Add TODO item for converting the remaining drivers. These helpers have been deprecated for years and many drivers have been updated to not use them. Still there are a few left and we occasionally receive new drivers build upon them. Marking them as deprecated will hopefully resolve these problems. The TODO items should be easy enough for getting new voluteers started on DRM driver development.

drm/mipi-dbi: Provide callbacks for atomic interfaces

2026-03-25T14:04:38+00:00

Refactor the existing simple-display callbacks such that they invoke helpers compatible with regular atomic modesetting. Allows for adding mipi-dbi drives that do not require simple-display helpers. Provide initializer macro for elements of the regular modesetting pipeline. These will be used by drivers to integrate mipi-dbi helpers. Also provide initializer macros for the plane formats. As the new helpers are DRM functions, add the drm_ prefix. Mipi-dbi interfaces currently lack this. v3: - fix uninitialized variable (David) - document public interfaces (David) - mention format macros in commit message (David) Signed-off-by: Thomas Zimmermann Acked-by: David Lechner Reviewed-by: Dmitry Baryshkov Link: https://patch.msgid.link/20260319160110.109610-4-tzimmermann@suse.de

drm/mipi-dbi: Only modify planes on enabled CRTCs

2026-03-25T14:04:24+00:00

Use drm_atomic_helper_commit_tail_rpm() as commit tail to update the plane after enabling the CRTC. Then remove the plane-update code from mipi_dbi_enable_flush() and inline the remaining backlight code where necessary. Mipi-dbi's current commit tail drm_atomic_helper_commit_tail() first updates the plane and then enables the CRTC. But the CRTC enablement includes power management that prevents the initial plane update from working. Hence, each mipi-dbi driver includes a plane update in their CRTC enablement; in the form of mipi_dbi_enable_flush() or custom code. Using drm_atomic_helper_commit_tail_rpm() enables the CRTC before any plane updates. Hence the additional plane update can be removed from mipi_dbi_enable_flush() and a number of drivers. This leaves backlight_enable() in the helper, which can now be inlined into affected drivers. Drivers now enable the CRTC plus an optional backlight and then automatically update the plane. In the case of disabling the display, drm_atomic_helper_commit_tail_rpm() only disables the CRTC without touching the plane at all. Mipi-dbi's mipi_dbi_pipe_disable() already contains the necessary logic. Removing the plane update from the CRTC enablement will also help with converting mipi-dbi from simple-pipe helpers to regular atomic helpers. v3: - st7586: remove unused variable v2: - ili9225: remove unused variables (David) - st7586: remove unused variables (David) Signed-off-by: Thomas Zimmermann Acked-by: David Lechner Reviewed-by: Dmitry Baryshkov Link: https://patch.msgid.link/20260319160110.109610-2-tzimmermann@suse.de
