However, it still depends on the setting of DRM_OFDRM so that both of these drivers cannot be builtin at the same time nor can one be builtin and the other one a loadable module. Build-tested successfully with all combination of DRM_OFDRM and FB_OF. This fixes a build issue that Michal reported when FB_OF=y and DRM_OFDRM=m: powerpc64-linux-ld: drivers/video/fbdev/offb.o:(.data.rel.ro+0x58): undefined reference to `cfb_fillrect' powerpc64-linux-ld: drivers/video/fbdev/offb.o:(.data.rel.ro+0x60): undefined reference to `cfb_copyarea' powerpc64-linux-ld: drivers/video/fbdev/offb.o:(.data.rel.ro+0x68): undefined reference to `cfb_imageblit' Signed-off-by: Randy Dunlap Suggested-by: Arnd Bergmann Cc: Masahiro Yamada Cc: Thomas Zimmermann Cc: Michal Suchánek Cc: linuxppc-dev@lists.ozlabs.org Cc: Daniel Vetter Cc: Helge Deller Cc: linux-fbdev@vger.kernel.org Cc: dri-devel@lists.freedesktop.org Acked-by: Thomas Zimmermann --- drivers/video/fbdev/Kconfig | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff -- a/drivers/video/fbdev/Kconfig b/drivers/video/fbdev/Kconfig --- a/drivers/video/fbdev/Kconfig +++ b/drivers/video/fbdev/Kconfig @@ -456,8 +456,8 @@ config FB_ATARI chipset found in Ataris. config FB_OF - bool "Open Firmware frame buffer device support" - depends on (FB = y) && PPC && (!PPC_PSERIES || PCI) + tristate "Open Firmware frame buffer device support" + depends on FB && PPC && (!PPC_PSERIES || PCI) depends on !DRM_OFDRM select APERTURE_HELPERS select FB_CFB_FILLRECT
