(Although, I really don't think CONFIG_PCI_MSI contributes anything significant to the kernel size.) [x86_64] text data bss dec hex filename 6816871 994760 668412 8480043 81652b vmlinux.msi 6786743 993952 668284 8448979 80ebd3 vmlinux.notmsi Kind of meh... I think it's a good idea to turn it on everywhere, and just twiddle the bit on or off. Then again, it would probably be better to just enable it everywhere and hope someone will fix the myriad of bugs. That's probably wishful thinking though. ;-) r, Kyle -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
