From b8dd786f9417e5885929bfe33a235c76a9c1c569 Mon Sep 17 00:00:00 2001 From: Yevgeny Petrilin Date: Mon, 22 Dec 2008 07:15:03 -0800 Subject: mlx4_core: Add support for multiple completion event vectors When using MSI-X mode, create a completion event queue for each CPU. Report the number of completion EQs in a new struct mlx4_caps member, num_comp_vectors, and extend the mlx4_cq_alloc() interface with a vector parameter so that consumers can specify which completion EQ should be used to report events for the CQ being created.
