drm/fb-helper: Perform all fbdev I/O with the same implementation

2022-11-05T16:05:54Z

Implement the fbdev's read/write helpers with the same functions. Use the generic fbdev's code as template. Convert all drivers. DRM's fb helpers must implement regular I/O functionality in struct fb_ops and possibly perform a damage update. Handle all this in the same functions and convert drivers. The functionality has been used as part of the generic fbdev code for some time. The drivers don't set struct drm_fb_helper.fb_dirty, so they will not be affected by damage handling. For I/O memory, fb helpers now provide drm_fb_helper_cfb_read() and drm_fb_helper_cfb_write(). Several drivers require these. Until now tegra used I/O read and write, although the memory buffer appears to be in system memory. So use _sys_ helpers now. v3: * fix docs (Javier) v2: * rebase onto vmwgfx changes Signed-off-by: Thomas Zimmermann Reviewed-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20221103151446.2638-18-tzimmermann@suse.de

drm/armada: remove _unlocked suffix in drm_gem_object_put_unlocked

2020-05-19T21:31:32Z

Spelling out _unlocked for each and every driver is a annoying. Especially if we consider how many drivers, do not know (or need to) about the horror stories involving struct_mutex. Just drop the suffix. It makes the API cleaner. Done via the following script: __from=drm_gem_object_put_unlocked __to=drm_gem_object_put for __file in $(git grep --name-only $__from); do sed -i "s/$__from/$__to/g" $__file; done Cc: Russell King Cc: David Airlie Cc: Daniel Vetter Signed-off-by: Emil Velikov Acked-by: Sam Ravnborg Acked-by: Thomas Zimmermann Link: https://patchwork.freedesktop.org/patch/msgid/20200515095118.2743122-17-emil.l.velikov@gmail.com

drm: Remove drm_fb_helper add, add all and remove connector calls

2020-03-06T13:19:58Z

drm_fb_helper_{add,remove}_one_connector() and drm_fb_helper_single_add_all_connectors() are dummy functions now and serve no purpose. Hence remove their calls. This is the preparatory step for removing the drm_fb_helper_{add,remove}_one_connector() functions from drm_fb_helper.h This removal is done using below sementic patch and unused variable compilation warnings are fixed manually. @@ @@ - drm_fb_helper_single_add_all_connectors(...); @@ expression e1; statement S; @@ - e1 = drm_fb_helper_single_add_all_connectors(...); - S @@ @@ - drm_fb_helper_add_one_connector(...); @@ @@ - drm_fb_helper_remove_one_connector(...); Changes since v1: * Squashed warning fixes into the patch that introduced the warnings (into 5/7) (Laurent, Emil, Lyude) Signed-off-by: Pankaj Bharadiya Reviewed-by: Laurent Pinchart Reviewed-by: Emil Velikov Reviewed-by: Alex Deucher Reviewed-by: Lyude Paul Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20200305120434.111091-6-pankaj.laxminarayan.bharadiya@intel.com
