7 The ``dpdk-test-regex`` tool is a Data Plane Development Kit (DPDK)
8 application that allows functional testing and performance measurement for
11 It is based on precompiled rule file, and an input file, both of them can
12 be selected using command-line options.
14 In general case, each PMD has its own rule file.
16 By default the test supports one QP per core, however a higher number of cores
17 and QPs can be configured. The QPs are evenly distributed on the cores. All QPs
18 are assigned the same number of segments of input file to parse. Given n QPs
19 (per core) - the enqueue/dequeue RegEx operations are interleaved as follows::
31 The test outputs the following data per QP and core:
33 * Performance, in gigabit per second.
35 * Matching results (rule id, position, length), for each job.
37 * Matching results in absolute location (rule id, position , length),
38 relative to the start of the input data.
44 * Supports only precompiled rules.
63 number of cores to use
66 only outputs the performance data
69 number of iteration to run
72 number of mbuf segment
75 print application options
81 **Step 1: Compile a rule file**
83 In order for the RegEx to work it must have a precompiled rule file.
84 to generate this file there is a need to use a RegEx compiler that matches the
87 **Step 2: Generate a data file**
89 The data file, will be used as a source data for the RegEx to work on.
91 **Step 3: Run the tool**
93 The tool has a number of command line options. Here is the sample command line::
95 ./dpdk-test-regex -a 83:00.0 -- --rules rule_file.rof2 --data data_file.txt --job 100 \
96 --nb_qps 4 --nb_lcores 2
