b7ba90ac - fbdev/omapfb: Initialize fb_ops to fbdev I/O-memory helpers

Wed, 27 Sep 2023 07:26:58 +0000

fbdev/omapfb: Initialize fb_ops to fbdev I/O-memory helpersInitialize the instance of struct fb_ops with fbdev initializermacros for framebuffers in I/O address space. Set the read/write,draw and mmap callbacks to the correct implementation and avoidimplicit defaults. Also select the necessary I/O helpers in Kconfig.Fbdev drivers sometimes rely on the callbacks being NULL for adefault implementation to be invoked; hence requiring the I/Ohelpers to be built in any case. Setting all callbacks in alldrivers explicitly will allow to make the I/O helpers optional.This benefits systems that do not use these functions.No functional changes.Signed-off-by: Thomas Zimmermann Acked-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20230927074722.6197-26-tzimmermann@suse.de List of files: /linux-6.15/drivers/video/fbdev/omap2/omapfb/Kconfig

701d2054 - fbdev: Make support for userspace interfaces configurable

Tue, 13 Jun 2023 11:07:13 +0000

fbdev: Make support for userspace interfaces configurableAdd Kconfig option CONFIG_FB_DEVICE and make the virtual fbdevdevice optional. If the new option has not been selected, fbdevdoes not create files in devfs, sysfs or procfs.Most modern Linux systems run a DRM-based graphics stack that usesthe kernel's framebuffer console, but has otherwise deprecated fbdevsupport. Yet fbdev userspace interfaces are still present.The option makes it possible to use the fbdev subsystem as consoleimplementation without support for userspace. This closes potentialentry points to manipulate kernel or I/O memory via framebuffers. Italso prevents the execution of driver code via ioctl or sysfs, bothof which might allow malicious software to exploit bugs in the fbdevcode.A small number of fbdev drivers require struct fbinfo.dev to beinitialized, usually for the support of sysfs interface. Make thesedrivers depend on FB_DEVICE. They can later be fixed if necessary.v3: * effect -> affect in Kconfig help (Daniel)v2: * set FB_DEVICE default to y (Geert) * comment on {get,put}_device() (Sam) * Kconfig fixes (Sam) * add TODO item about FB_DEVICE dependencies (Sam)Signed-off-by: Thomas Zimmermann Acked-by: Greg Kroah-Hartman Reviewed-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20230613110953.24176-39-tzimmermann@suse.de List of files: /linux-6.15/drivers/video/fbdev/omap2/omapfb/Kconfig

1c6aac92 - omapfb: allow compilation only if DRM_OMAP is disabled

Wed, 09 Dec 2015 16:21:58 +0000

omapfb: allow compilation only if DRM_OMAP is disabledAt the moment omapfb and omapdrm can be compiled at the same time, ifboth are modules. However, they can't be both loaded, as they use thesame hardware. This has been mostly for compile testing.To make it clear that omapfb and omapdrm are mutually exclusive drivers,this patch makes omapfb available only if omapdrm is disabled.Signed-off-by: Tomi Valkeinen Acked-by: Dave Airlie Acked-by: Rob Clark List of files: /linux-6.15/drivers/video/fbdev/omap2/omapfb/Kconfig

It contains generic video relatedfiles, directories for backlight, console, linux logo, lots of fbdevdevice drivers, fbdev framework files.Make some order into the chaos by creating drivers/video/fbdevdirectory, and move all fbdev related files there.No functionality is changed, although I guess it is possible that somesubtle Makefile build order related issue could be created by thispatch.Signed-off-by: Tomi Valkeinen Acked-by: Laurent Pinchart Acked-by: Geert Uytterhoeven Acked-by: Rob Clark Acked-by: Jingoo Han Acked-by: Daniel Vetter List of files: /linux-6.15/drivers/video/fbdev/omap2/omapfb/Kconfig
