Subject: [dpdk-dev] [PATCH v3] app/test-regex: add RegEx test application
Date: Wed, 29 Jul 2020 11:26:06 +0000 [thread overview]
Message-ID: <1596021966-10450-1-git-send-email-orika@mellanox.com> (raw)
In-Reply-To: <1595793496-73205-1-git-send-email-orika@mellanox.com>
From: Yuval Avnery <yuvalav@mellanox.com>
Following the new RegEx class.
There is a need to create a dedicated test application in order to
validate this class and PMD.
Unlike net device this application loads data from a file.
This commit introduces the new RegEx test app.
The basic app flow:
1. Configure the RegEx device to use one queue, and set the rule
database, using precompiled file.
2. Allocate mbufs based on the requested number of jobs, each job will
i get one mbuf.
3. Enqueue as much as possible jobs.
4. Dequeue jobs.
5. if the number of dequeue jobs < requested number of jobs job to step

v3:
* Fix possible issue in case of error.
v2:
* Remove rule file and data generation data.
* Address ML comments.

+dpdk-test-regex Tool
+====================
+
+The ``dpdk-test-regex`` tool is a Data Plane Development Kit (DPDK)
+application that allows functional testing and performance measurement for
+the RegEx PMDs.
+The test supports only one core and one PMD.
+It is based on precompiled rule file, and an input file, both of them can
+be selected using command-line options.
+
+In general case, each PMD has its own rule file.
+
+The test outputs the following data:
+
+* Performance, in gigabit per second.
+
+* Matching results (rule id, position, length), for each job.
+
+* Matching results in absolute location (rule id, position , length),
+ relative to the start of the input data.
+
+
+Limitations
+~~~~~~~~~~~
+
+* Only one queue is supported.
+
+* Supports only precompiled rules.
+
+
+Application Options
+~~~~~~~~~~~~~~~~~~~
+
+* ``--rules NAME``: precompiled rule file
+
+* ``--data NAME``: data file to use
+
+* ``--nb_jobs N``: number of jobs to use
+
+* ``--perf N``: only outputs the performance data
+
+* ``--nb_iter N``: number of iteration to run
+
+* ``--help``: prints this help
+
+
+Compiling the Tool
+------------------
+
+The ``dpdk-test-regex`` application depends on RegEx lib ``rte_regexdev``.
+
+
+Running the Tool
+----------------
+
+**Step 1: Compile a rule file**
+
+In order for the RegEx to work it must have a precompiled rule file.
+to generate this file there is a need to use a RegEx compiler that matches the
+RegEx PMD.
+
+**Step 2: Generate a data file**
+
+The data file, will be used as a source data for the RegEx to work on.
+
+**Step 3: Run the tool**
+
+The tool has a number of command line options. Here is the sample command line::
+
+ .testregex -w 83:00.0 -- --rules rule_file.rof2 --data data_file.txt --job 100
