Subject: [PATCH 10/16] vdpa/mlx5: add task ring for MT management
Date: Mon, 6 Jun 2022 14:20:56 +0300	[thread overview]
Message-ID: <20220606112109.208873-20-lizh@nvidia.com> (raw)
In-Reply-To: <20220606112109.208873-1-lizh@nvidia.com>

The configuration threads tasks need a container to
support multiple tasks assigned to a thread in parallel.
Use rte_ring container per thread to manage
the thread tasks without locks.
The caller thread from the user context opens a task to
a thread and enqueue it to the thread ring.
The thread polls its ring and dequeue tasks.
That’s why the ring should be in multi-producer
and single consumer mode.
Anatomic counter manages the tasks completion notification.
The threads report errors to the caller by
a dedicated error counter per task.
