So I dug into this, and the problem seems to be that CONFIG_SCREEN_INFO is not defined in that config. I can't figure out how this should work in that case or why this is not a problem in drivers/firmware/sysfb.c. Something like this works: diff --git a/drivers/video/aperture.c b/drivers/video/aperture.c index 56a5a0bc2b1af..50e98210c9fe5 100644 --- a/drivers/video/aperture.c +++ b/drivers/video/aperture.c @@ -347,7 +347,9 @@ EXPORT_SYMBOL(__aperture_remove_legacy_vga_devices); */ int aperture_remove_conflicting_pci_devices(struct pci_dev *pdev, const char *name) { +#if defined(CONFIG_SCREEN_INFO) struct screen_info *si = &screen_info; +#endif bool primary = false; resource_size_t base, size; int bar, ret = 0; @@ -355,8 +357,10 @@ int aperture_remove_conflicting_pci_devices(struct pci_dev *pdev, const char *na if (pdev == vga_default_device()) primary = true; +#if defined(CONFIG_SCREEN_INFO) if (pdev == screen_info_pci_dev(si)) sysfb_disable(); +#endif for (bar = 0; bar < PCI_STD_NUM_BARS; ++bar) { if (!(pci_resource_flags(pdev, bar) & IORESOURCE_MEM)) But that can't be the right fix...
