From b4aa0163056b6c70029b6e8619ce07c274351f42 Mon Sep 17 00:00:00 2001 From: Matthew Garrett Date: Mon, 16 Apr 2012 16:26:05 -0400 Subject: efifb: Implement vga_default_device() (v2) EFI doesn't typically make use of the legacy VGA ROM, but it may still be configured to pass that through to a given video device. This may lead to an inaccurate choice of default video device. Add support to efifb to pick out the correct active video device. v2: fix if->ifdef Signed-off-by: Matthew Garrett Acked-by: hpa@zytor.com Cc: matt.fleming@intel.com Signed-off-by: Dave Airlie --- arch/x86/include/asm/vga.h | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'arch/x86/include/asm/vga.h') diff --git a/arch/x86/include/asm/vga.h b/arch/x86/include/asm/vga.h index c4b9dc2f67c..44282fbf7bf 100644 --- a/arch/x86/include/asm/vga.h +++ b/arch/x86/include/asm/vga.h @@ -17,4 +17,10 @@ #define vga_readb(x) (*(x)) #define vga_writeb(x, y) (*(y) = (x)) +#ifdef CONFIG_FB_EFI +#define __ARCH_HAS_VGA_DEFAULT_DEVICE +extern struct pci_dev *vga_default_device(void); +extern void vga_set_default_device(struct pci_dev *pdev); +#endif + #endif /* _ASM_X86_VGA_H */ -- cgit v1.2.3-70-g09d2
