> Subject: [PATCH v3 0/4] Add dual threading in QAT PMD
>
> 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.
> Additional option added is to set minumum enqueue burst
> threshold which may help to reduce MMIO write occurances.
>
> v3:
> - added minimum threshold option
> v2:
> - clarified wording in docs

> Arek Kusztal (1):

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