From 20cf4e026730104892fa1268de0371a631cee294 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 29 Jul 2019 13:22:09 -0400 Subject: rdma: Enable ib_alloc_cq to spread work over a device's comp_vectors MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Send and Receive completion is handled on a single CPU selected at the time each Completion Queue is allocated. Typically this is when an initiator instantiates an RDMA transport, or when a target accepts an RDMA connection. Some ULPs cannot open a connection per CPU to spread completion workload across available CPUs and MSI vectors. For such ULPs, provide an API that allows the RDMA core to select a completion vector based on the device's complement of available comp_vecs. ULPs that invoke ib_alloc_cq() with only comp_vector 0 are converted to use the new API so that their completion workloads interfere less with each other.
