arch: Rename fbdev header and source files

2024-05-03T15:07:50Z

The per-architecture fbdev code has no dependencies on fbdev and can be used for any video-related subsystem. Rename the files to 'video'. Use video-sti.c on parisc as the source file depends on CONFIG_STI_CORE. On arc, arm, arm64, sh, and um the asm header file is an empty wrapper around the file in asm-generic. Let Kbuild generate the file. The build system does this automatically. Only um needs to generate video.h explicitly, so that it overrides the host architecture's header. The latter would otherwise interfere with the build. Further update all includes statements, include guards, and Makefiles. Also update a few strings and comments to refer to video instead of fbdev. v3: - arc, arm, arm64, sh: generate asm header via build system (Sam, Helge, Arnd) - um: rename fb.h to video.h - fix typo in commit message (Sam) Signed-off-by: Thomas Zimmermann Reviewed-by: Sam Ravnborg Cc: Vineet Gupta Cc: Catalin Marinas Cc: Will Deacon Cc: Huacai Chen Cc: WANG Xuerui Cc: Geert Uytterhoeven Cc: Thomas Bogendoerfer Cc: "James E.J.

backlight: Match backlight device against struct fb_info.bl_dev

2024-03-28T10:08:47Z

Framebuffer drivers for devices with dedicated backlight are supposed to set struct fb_info.bl_dev to the backlight's respective device. Use the value to match backlight and framebuffer in the backlight core code. The code first tests against struct backlight_ops.check_ops. If this test succeeds, it performs the test against fbdev. So backlight drivers can override the later test as before. Fbdev's backlight support depends on CONFIG_FB_BACKLIGHT. To avoid ifdef in the code, the new helper fb_bl_device() returns the backlight device, or NULL if the config option has been disabled. The test in the backlight code will then do nothing. v4: * declare empty fb_bl_device() as static inline * export fb_bl_device() v3: * hide ifdef in fb_bl_device() (Lee) * no if-else blocks (Andy) Signed-off-by: Thomas Zimmermann Reviewed-by: Daniel Thompson Reviewed-by: Javier Martinez Canillas Link: https://lore.kernel.org/r/20240305162425.23845-2-tzimmermann@suse.de Signed-off-by: Lee Jones

drm/omapdrm: Fix console with deferred ops

2024-03-18T11:43:39Z

Commit 95da53d63dcf ("drm/omapdrm: Use regular fbdev I/O helpers") stopped console from updating for command mode displays because there is no damage handling in fb_sys_write() unlike we had earlier in drm_fb_helper_sys_write(). Let's fix the issue by adding FB_GEN_DEFAULT_DEFERRED_DMAMEM_OPS and FB_DMAMEM_HELPERS_DEFERRED as suggested by Thomas. We cannot use the FB_DEFAULT_DEFERRED_OPS as fb_deferred_io_mmap() won't work properly for write-combine.

fbcon: Increase maximum font width x height to 64 x 128

2024-03-16T07:29:48Z

By using bitmaps we actually support whatever size we would want, but the console currently limits fonts to 64x128 (which gives 60x16 text on 4k screens), so we don't need more for now, and we can easily increase later. Signed-off-by: Samuel Thibault Signed-off-by: Helge Deller
