It wasnt enabled in any default configs, but i believe its functional even earlier. Atleast when i changed the method for irq migration via /proc, i remember testing on ia64 on ixgb driver. I havent followed the register_ops() discussion but believe it just changed the default vector allocation to arch/platform types. But the core msi should have worked even earlier. Cheers, ashok
