From 3f0e54fe00de7aec060afd50bfb288a8a43d0689 Mon Sep 17 00:00:00 2001 From: Michael Baum Date: Wed, 3 Nov 2021 20:35:10 +0200 Subject: [PATCH] common/mlx5: fix UAR allocation diagnostics messages Depending on kernel capabilities and rdma-core version the mapping of UAR (User Access Region) of desired memory caching type (non-cached or write combining) might fail. The PMD implements the flexible strategy of UAR mapping, alternating the type of caching to succeed. During this process the failure diagnostics messages are emitted. These messages are merely diagnostics ones and the logging level should be adjusted to DEBUG.
