The DRM subsystem has a fbdev emulation layer, but depends on CONFIG_FB and so it can only be enabled if that dependency is enabled as well. That means fbdev drivers have to be explicitly disabled if users want to enable CONFIG_FB, only to use fbcon and/or the DRM fbdev emulation layer. This patch introduces a non-visible CONFIG_FB_CORE symbol that could be enabled just to have core support needed for CONFIG_DRM_FBDEV_EMULATION, allowing CONFIG_FB to be disabled (and automatically disabling all the fbdev drivers). Nothing from fb_backlight.o and fbmon.o is used by the DRM fbdev emulation layer so these two objects can be compiled out when CONFIG_FB is disabled. Signed-off-by: Javier Martinez Canillas --- Changes in v4: - Fix menuconfig hierarchy that was broken in v3 (Arnd Bergmann). Changes in v3: - Really make a hidden symbol by removing the prompt (Arnd Bergmann). - Change FB_CORE to config instead of menuconfig (Arnd Bergmann). - Keep "depends on FB" for FIRMWARE_EDID (Arnd Bergmann). - Compile out fb_backlight.o and fbmon.o that are only needed for FB (Arnd Bergmann). - Make FB_DEVICE to depend on FB_CORE instead of selecting it. Changes in v2: - Keep "depends on FB" for FB_DDC, FB_HECUBA, FB_SVGALIB, FB_MACMODES, FB_BACKLIGHT, FB_MODE_HELPERS and FB_TILEBLITTING (Arnd Bergmann). - Don't change the fb.o object name (Arnd Bergmann). - Make FB_CORE a non-visible Kconfig symbol instead (Thomas Zimmermann). arch/x86/Makefile | 2 +- arch/x86/video/Makefile | 2 +- drivers/video/console/Kconfig | 2 +- drivers/video/fbdev/Kconfig | 10 ++++++++-- drivers/video/fbdev/core/Kconfig | 30 +++++++++++++++++------------- drivers/video/fbdev/core/Makefile | 8 ++++---- 6 files changed, 32 insertions(+), 22 deletions(-) diff --git a/arch/x86/Makefile b/arch/x86/Makefile index b39975977c03..89a02e69be5f 100644 --- a/arch/x86/Makefile +++ b/arch/x86/Makefile @@ -259,7 +259,7 @@ drivers-$(CONFIG_PCI) += arch/x86/pci/ # suspend and hibernation support drivers-$(CONFIG_PM) += arch/x86/power/ -drivers-$(CONFIG_FB) += arch/x86/video/ +drivers-$(CONFIG_FB_CORE) += arch/x86/video/ #### # boot loader support.
