By Saeed, First six patches of the series are meant to address a performance issue and should provide a performance boost for multi core IRQ interrupt hungry workloads. The issue is fixed in the first patch, all other patches are meant to refactor the code in light of this fix. The problem it comes to fix, is a shared spinlock accessed across all HCA IRQs which protects the CQ database. To solve this we simply move the CQ database and its spinlock to be per EQ (IRQ), thus per core. By Yonatan, Fragmented completion queue (CQ) for RDMA, core driver implementation to create fragmented CQ buffers rather than one large contiguous memory buffer, the implementation scheme already exist and used by the netdev CQs, the patch shares that code with the rdma CQ creation flow and makes use of the new API in mlx5_ib driver. ==================== Signed-off-by: David S.
