Bruno Prémont 20cde69402 x86, ia64: Move EFI_FB vga_default_device() initialization to pci_vga_fixup() ... Commit b4aa016305 ("efifb: Implement vga_default_device() (v2)") added efifb vga_default_device() so EFI systems that do not load shadow VBIOS or setup VGA get proper value for boot_vga PCI sysfs attribute on the corresponding PCI device. Xorg doesn't detect devices when boot_vga=0, e.g., on some EFI systems such as MacBookAir2,1. Xorg detects the GPU and finds the DRI device but then bails out with "no devices detected". Note: When vga_default_device() is set boot_vga PCI sysfs attribute reflects its state. When unset this attribute is 1 whenever IORESOURCE_ROM_SHADOW flag is set. With introduction of sysfb/simplefb/simpledrm efifb is getting obsolete while having native drivers for the GPU also makes selecting sysfb/efifb optional. Remove the efifb implementation of vga_default_device() and initialize vgaarb's vga_default_device() with the PCI GPU that matches boot screen_info in pci_fixup_video(). [bhelgaas: remove unused "dev" in efifb_setup()] Fixes: b4aa016305 ("efifb: Implement vga_default_device() (v2)") Tested-by: Anibal Francisco Martinez Cortina <linuxkid.zeuz@gmail.com> Signed-off-by: Bruno Prémont <bonbons@linux-vserver.org> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Matthew Garrett <matthew.garrett@nebula.com> CC: stable@vger.kernel.org # v3.5+		2014-07-10 16:48:48 -06:00
