Matthew Wilcox and I have previously volunteered to get MSI working on parisc arch. parisc, like systems with Local SAPIC, only operates on transaction based interrupts at the CPU level. We need an arch hook to set the target address of the CPU instead of looking at ID/EID bits but haven't proposed anything concrete yet. My understanding is SGI needs the same thing for Altix/SN2 platforms. thanks, grant - 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/
