At least for the AMD GART IOMMU I would prefer if that was not done. It has a pci config space access in a time critical path (flush). And Family10h supports accessing the northbridge using mmconfig. I believe the tigon3 driver also does config space access frequently on some chips. Also there are still the old x86 Macs where conf1 doesn't work. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
