Subject: [dpdk-dev] [PATCH v1 04/16] net/mlx5: introduce shared UAR resource
Date: Fri, 10 Jul 2020 09:48:38 +0000 [thread overview]
Message-ID: <1594374530-24659-4-git-send-email-viacheslavo@mellanox.com> (raw)
In-Reply-To: <1594374530-24659-1-git-send-email-viacheslavo@mellanox.com>
This is preparation step before moving the Tx queue creation
to the DevX approach. Some features require the shared UAR
for Tx queues and scheduling completion queues, the patch
manages the shared UAR.
