drm/sitronix: move tiny Sitronix drivers to their own subdir

2025-05-12T08:26:40Z

We start to have support many Sitronix displays in the tiny directory, and we expect more to come. Move them to their own subdirectory.

drm: remove driver date from struct drm_driver and all drivers

2024-12-05T10:35:42Z

We stopped using the driver initialized date in commit 7fb8af6798e8 ("drm: deprecate driver date") and (eventually) started returning "0" for drm_version ioctl instead. Finish the job, and remove the unused date member from struct drm_driver, its initialization from drivers, along with the common DRIVER_DATE macros. v2: Also update drivers/accel (kernel test robot) Reviewed-by: Javier Martinez Canillas Acked-by: Alex Deucher Acked-by: Simon Ser Acked-by: Jeffrey Hugo Acked-by: Lucas De Marchi Acked-by: Dmitry Baryshkov # msm Reviewed-by: Thomas Zimmermann Link: https://patchwork.freedesktop.org/patch/msgid/1f2bf2543aed270a06f6c707fd6ed1b78bf16712.1733322525.git.jani.nikula@intel.com Signed-off-by: Jani Nikula

drm/tiny/st7586: Use fbdev-dma

2024-05-02T09:33:31Z

Implement fbdev emulation with fbdev-dma. Fbdev-dma now supports damage handling, which is required by st7586. Avoids the overhead of fbdev-generic's additional shadow buffering.

drm/format-helper: Pass format-conversion state to helpers

2023-11-14T09:16:53Z

Pass an instance of struct drm_format_conv_state to DRM's format conversion helpers. Update all callers. Most drivers can use the format-conversion state from their shadow- plane state. The shadow plane's destroy function releases the allocated buffer. Drivers will later be able to allocate a buffer of appropriate size in their plane's atomic_check code. The gud driver uses a separate thread for committing updates. For now, the update worker contains its own format-conversion state. Images in the format-helper tests are small. The tests preallocate a static page for the temporary buffer. Unloading the module releases the memory. v6: * update patch for ssd132x support v5: * avoid using unusupported shadow-plane state in repaper (Noralf) * fix documentation (Noralf, kernel test robot) v3: * store buffer in shadow-plane state (Javier, Maxime) * replace ARRAY_SIZE() with sizeof() (Jani) Signed-off-by: Thomas Zimmermann Reviewed-by: Javier Martinez Canillas Tested-by: Javier Martinez Canillas # ssd130x Cc: Noralf Trønnes Cc: Javier Martinez Canillas Cc: Gerd Hoffmann Cc: David Lechner Link: https://patchwork.freedesktop.org/patch/msgid/20231009141018.11291-4-tzimmermann@suse.de

drm/mipi-dbi: Move drm_dev_{enter, exit}() out from fb_dirty functions

Call drm_dev_enter() and drm_dev_exit() in the outer-most callbacks of the modesetting pipeline. If drm_dev_enter() fails, the driver can thus avoid unnecessary work.

drm/mipi-dbi: Support shadow-plane state

2022-12-05T13:20:43Z

Implement MIPI DBI planes with struct drm_shadow_plane_state, so that the respective drivers can use the vmap'ed GEM-buffer memory. Implement state helpers, the {begin,end}_fb_access helpers and wire up everything. With this commit, MIPI DBI drivers can access the GEM object's memory that is provided by shadow-plane state.
