For openSUSE kernel-source.git master branch I see: $ grep -r CONFIG_DRM_FBDEV_OVERALLOC config/ config/armv7hl/default:CONFIG_DRM_FBDEV_OVERALLOC=100 config/armv7hl/lpae:CONFIG_DRM_FBDEV_OVERALLOC=100 config/ppc64le/default:CONFIG_DRM_FBDEV_OVERALLOC=100 config/i386/pae:CONFIG_DRM_FBDEV_OVERALLOC=100 config/ppc64/default:CONFIG_DRM_FBDEV_OVERALLOC=100 config/x86_64/default:CONFIG_DRM_FBDEV_OVERALLOC=100 config/armv6hl/default:CONFIG_DRM_FBDEV_OVERALLOC=100 config/arm64/default:CONFIG_DRM_FBDEV_OVERALLOC=100 Similar to what Peter said, on the Raspberry Pi we would usually use vc4 drm; but some users have run into issues with vc4 not working with certain monitors, so they may blacklist vc4 and use efifb instead. Adding Alex and Petr in case more discussion is needed.
