I beleive it doesn the same with IO space (but I didn't check). The lack of PCI_COMMAND_INVALIDATE can be considered as an OF bug if the card already has PCI_COMMAND_MASTER set as a default. I think the kernel should add this to all devices at fixup time. (It should be harmless for non-master devices anyway). -- Perso. e-mail: Work e-mail: BenH.
