void vga_set_legacy_decoding ( struct pci_dev pdev,
unsigned int  decodes 


: pci device of the VGA card : bit mask of what legacy regions the card decodes

Indicates to the arbiter if the card decodes legacy VGA IOs, legacy VGA Memory, both, or none. All cards default to both, the card driver (fbdev for example) should tell the arbiter if it has disabled legacy decoding, so the card can be left out of the arbitration process (and can be safe to take interrupts at any time.
