* fbdev/hpfb: Initialize fb_ops to fbdev I/O-memory helpersThomas Zimmermann2023-10-191-0/+2
| | | | | | | | | | | | | | | | | | | Initialize the instance of struct fb_ops with fbdev initializer macros for framebuffers in I/O address space. Set the read/write, draw and mmap callbacks to the correct implementation and avoid implicit defaults. Also select the necessary I/O helpers in Kconfig. Fbdev drivers sometimes rely on the callbacks being NULL for a default implementation to be invoked; hence requiring the I/O helpers to be built in any case. Setting all callbacks in all drivers explicitly will allow to make the I/O helpers optional. This benefits systems that do not use these functions. No functional changes.

* fbdev: Remove FBINFO_DEFAULT from static structsThomas Zimmermann2023-07-241-1/+0
| | | | | | | | | | | | | | | | | | The flag FBINFO_DEFAULT is 0 and has no effect, as struct fbinfo.flags has been allocated to zero by a static declaration. So do not set it. Flags should signal differences from the default values. After cleaning up all occurrences of FBINFO_DEFAULT, the token will be removed. v4: * clarify commit message (Geert, Dan) v2: * fix commit message (Miguel) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Sam Ravnborg <sam@ravnborg.org> Cc: Helge Deller <deller@gmx.de> Link: https://patchwork.freedesktop.org/patch/msgid/20230715185343.7193-3-tzimmermann@suse.de

| | | | | | | | | The various *fb_setup() and *fb_init() functions are only used locally, so they should be static. Most of them do not need forward declarations, so remove these where appropriate. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Helge Deller <deller@gmx.de>

* video: constify fb ops across all driversJani Nikula2019-12-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Now that the fbops member of struct fb_info is const, we can start making the ops const as well. This does not cover all drivers; some actually modify the fbops struct, for example to adjust for different configurations, and others do more involved things that I'd rather not touch in practically obsolete drivers. Mostly this is the low hanging fruit where we can add "const" and be done with it. v3: - un-constify atyfb, mb862xx, nvidia and uvesabf (0day) v2: - fix typo (Christophe de Dinechin) - use "static const" instead of "const static" in mx3fb.c - also constify smscufx.c Cc: linux-fbdev@vger.kernel.org Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/ce67f14435f3af498f2e8bf35ce4be11f7504132.1575390740.git.jani.nikula@intel.com

* video: move fbdev to drivers/video/fbdevTomi Valkeinen2014-04-171-0/+429
The drivers/video directory is a mess. It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.
