yeah it'd be nice if I could just call a function for it rather than poking into kvm internals ;) > Right now I'm thinking about using the signal machinery since it appears > to do exactly the right thing. signals are *expensive* though. If you design an interrupt interface, it'd rock if you could make it such that it is "raise <this> interrupt within <x> miliseconds from now", rather than making it mostly synchronous. That way irq mitigation becomes part of the interface rather than having to duplicate it all over the virtual drivers... -- if you want to mail me at work (you don't), use arjan (at) linux.intel.com Test the interaction between Linux and your BIOS via http://www.linuxfirmwarekit.org - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
