config [31mCONFIG_VGA_ARB[0m bool "VGA Arbitration" if [31mCONFIG_EXPERT[0m default y depends on ([31mCONFIG_PCI[0m && ![31mCONFIG_S390[0m) help Some "legacy" VGA devices implemented on [31mCONFIG_PCI[0m typically have the same hard-decoded addresses as they did on [31mCONFIG_ISA[0m. When multiple [31mCONFIG_PCI[0m devices are accessed at same time they need some kind of coordination. Please see Documentation/vgaarbiter.txt for more details.
