Subject: [dpdk-dev] [PATCH v1 2/6] app/regex: support multi QPs
Date: Wed, 16 Dec 2020 16:49:27 +0000
Message-ID: <20201216164931.1517-3-ophirmu@nvidia.com> (raw)
In-Reply-To: <20201216164931.1517-1-ophirmu@nvidia.com>

Up to this commit the regex application used one QP which was assigned a
number of jobs, each with a different segment of a file to parse.  This
commit adds support for multiple QPs assignments. All QPs will be
assigned the same number of jobs, with the same segments of file to
parse. It will enable comparing functionality with different numbers of
QPs. All queues are managed on one core with one thread. This commit
focuses on changing routines API to support multi QPs, mainly, QP scalar
variables are replaced by per-QP struct instance.  The enque/deque
operations are interleaved as follows:
 enque(QP #1)
 enque(QP #2)
 ...
 enque(QP #n)
 deque(QP #1)
 deque(QP #2)
 ...
 deque(QP #n)

A new parameter 'nb_qps' was added to configure the number of QPs:
 --nb_qps <num of qps>.
If not configured, nb_qps is set to 1 by defalut.
