The conventional use of MSI is for a PCI adapter to generate processor interrupts by writing to a local APIC. But I've seen some things that lead me to believe it would also allow an adapter to write to things other than a local APIC, i.e., to memory.
If so, is that a useful capability that should be exposed through the Linux MSI interface? - 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/
