It was never clear to me that "number of CQs attached" is a particularly good way to choose an interrupt vector. It would seem to me that we would want something that takes into account CPU affinity, possibly NUMA effects, etc. Also I don't think there were any performance numbers posted for these changes, were there? (BTW It would be interesting to know how much improvement one could get on modern 2/4 socket systems by allocating EQ, CQ, QP, etc. memory on the "right" NUMA node -- where I don't know if "right" means on the node closest to the adapter or the node where the CPU will access the queue) -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
