It's just that in the past Dave Miller used, let's say, "colorful" language whenever someone mentioned the fact that the original Itanium machines didn't have a hardware I/O TLB. The new Itanium 2 machines from hp have a chipset with heritage from pa-risc, so they don't have this limitation (to be fair to Intel though, I don't think the lack of a hw I/O TLB is a huge issue anymore, given that nowadays you can readily find all kinds of PCI controllers that support DAC, including network adapters). --david - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
