Hi, I am sorry to repeat the question, but so far I didn't get an answer on whether MSI (Message Signaled Interrupts) handling is supposed to respect with /proc/irq/*/smp_affinity mask bits. No matter what affinity bits I am setting on my system, all MSIs are processed by CPU#0.
at least on 2.6.18 and 2.6.19, I've used smp_affinity and MSI vectors with no problems. I have seen some quite weird behavior, where reading smp_affinity back reports no change, but the interrupts actually change CPUs so it is working. I've been doing this on Intel processors/chipsets however, maybe that is why it doesn't work for you? - To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
