revision 1.29
date: 2010/09/06 12:30:35; author: kettenis; state: Exp; lines: +4 -5
Some stupid hardware marks PCI BARs as prefetchable that aren't side-effect
free. Mapping those with BUS_SPACE_MAP_PREFETCHABLE can have disastrous
effects, like the NMIs observed by jsg@ with certain Intel 10Gb Ethernet
devices. So stop trusting the devices and instead require drivers to
explicitly pass the BUS_SPACE_MAP_PREFECTHABLE flag to pci_mapreg_map().
