Subject: [dpdk-dev] [PATCH v2 0/3] Add dual threading in QAT PMD
Date: Fri,  6 Sep 2019 17:12:26 +0100	[thread overview]
Message-ID: <1567786349-25353-1-git-send-email-fiona.trahe@intel.com> (raw)
In-Reply-To: <1567784675-1401-1-git-send-email-fiona.trahe@intel.com>

Remove the limitation whereby enqueue and dequeue must be
done in same thread.
The inflight calculation is reworked to be thread-safe for 2
threads - note this is not general multi-thread support, i.e
all enqueues to a qp must still be done in one thread and
all dequeues must be done in one thread, but enqueues and
dequeues may be in separate threads.
As the tail-coalescing feature is not
threadsafe it is removed first.

v2 changes:
 - clarified wording in docs

Fiona Trahe (3):
  common/qat: remove tail write coalescing feature
  common/qat: move max inflights param into qp
  common/qat: add dual thread support
