mappings. Instead, they should be first mapping to an RSS bucket and then querying the RSS bucket -> CPU ID mapping to figure out the target CPU. When (if?) RSS rebalancing is implemented or some other (non round-robin) distribution of work from buckets to CPU IDs, various bits of code - both userland and kernel - will need to know how this mapping works. So, to support this: * Add a new function rss_m2bucket() - this maps an mbuf to a given bucket. Anything which is currently doing hash -> CPU work may instead wish to do hash -> bucket, and then query the bucket->cpuid map for which CPU it belongs on. Or, map it to a bucket, then re-pin that bucket -> CPU during a rebalance operation. * For userland applications which wish to exploit affinity to RSS buckets, the bucket -> CPU ID mapping is now available via a sysctl. net.inet.rss.bucket_mapping lists the bucket to CPU ID mapping via a list of bucket:cpu pairs. |
