4 dpdk-test-crypto-perf Application
5 =================================
7 The ``dpdk-test-crypto-perf`` tool is a Data Plane Development Kit (DPDK)
8 utility that allows measuring performance parameters of PMDs available in the
9 crypto tree. There are available two measurement types: throughput and latency.
10 User can use multiply cores to run tests on but only
11 one type of crypto PMD can be measured during single application
12 execution. Cipher parameters, type of device, type of operation and
13 chain mode have to be specified in the command line as application
14 parameters. These parameters are checked using device capabilities
19 On hardware devices the cycle-count doesn't always represent the actual offload
20 cost. The cycle-count only represents the offload cost when the hardware
21 accelerator is not fully loaded, when loaded the cpu cycles freed up by the
22 offload are still consumed by the test tool and included in the cycle-count.
23 These cycles are consumed by retries and inefficient API calls enqueuing and
24 dequeuing smaller bursts than specified by the cmdline parameter. This results
25 in a larger cycle-count measurement and should not be interpreted as an offload
26 cost measurement. Using "pmd-cyclecount" mode will give a better idea of
27 actual costs of hardware acceleration.
29 On hardware devices the throughput measurement is not necessarily the maximum
30 possible for the device, e.g. it may be necessary to use multiple cores to keep
31 the hardware accelerator fully loaded and so measure maximum throughput.
37 It is possible linearized input segmented packets just before crypto operation
38 for devices which doesn't support scatter-gather, and allows to measure
39 performance also for this use case.
41 To set on the linearization options add below definition to the
42 ``cperf_ops.h`` file::
44 #define CPERF_LINEARIZATION_ENABLE
47 Running the Application
48 -----------------------
50 The tool application has a number of command line options:
52 .. code-block:: console
54 dpdk-test-crypto-perf [EAL Options] -- [Application Options]
59 The following are the EAL command-line options that can be used in conjunction
60 with the ``dpdk-test-crypto-perf`` application.
61 See the DPDK Getting Started Guides for more information on these options.
63 * ``-c <COREMASK>`` or ``-l <CORELIST>``
65 Set the hexadecimal bitmask of the cores to run on. The corelist is a
70 Add a PCI device in allow list.
72 * ``--vdev <driver><id>``
79 The following are the application command-line options:
83 Set test type, where ``type`` is one of the following::
96 Set the number of mbufs to be allocated in the mbuf pool.
100 Set the number of total operations performed.
104 Set the number of packets per burst.
107 * Single value (i.e. ``--burst-sz 16``)
108 * Range of values, using the following structure ``min:inc:max``,
109 where ``min`` is minimum size, ``inc`` is the increment size and ``max``
110 is the maximum size (i.e. ``--burst-sz 16:2:32``)
111 * List of values, up to 32 values, separated in commas (i.e. ``--burst-sz 16,24,32``)
113 * ``--buffer-sz <n>``
115 Set the size of single packet (plaintext or ciphertext in it).
118 * Single value (i.e. ``--buffer-sz 16``)
119 * Range of values, using the following structure ``min:inc:max``,
120 where ``min`` is minimum size, ``inc`` is the increment size and ``max``
121 is the maximum size (i.e. ``--buffer-sz 16:2:32``)
122 * List of values, up to 32 values, separated in commas (i.e. ``--buffer-sz 32,64,128``)
126 Set the distribution of packet sizes.
128 A list of weights must be passed, containing the same number of items than buffer-sz,
129 so each item in this list will be the weight of the packet size on the same position
130 in the buffer-sz parameter (a list have to be passed in that parameter).
134 To test a distribution of 20% packets of 64 bytes, 40% packets of 100 bytes and 40% packets
135 of 256 bytes, the command line would be: ``--buffer-sz 64,100,256 --imix 20,40,40``.
136 Note that the weights do not have to be percentages, so using ``--imix 1,2,2`` would result
137 in the same distribution
139 * ``--segment-sz <n>``
141 Set the size of the segment to use, for Scatter Gather List testing.
142 By default, it is set to the size of the maximum buffer size, including the digest size,
143 so a single segment is created.
145 * ``--devtype <name>``
147 Set device type, where ``name`` is one of the following::
163 * ``--optype <name>``
165 Set operation type, where ``name`` is one of the following::
176 For GCM/CCM algorithms you should use aead flag.
180 Enable session-less crypto operations mode.
184 Enable out-of-place crypto operations mode.

271 Set AEAD algorithm name, where ``name`` is one
277 * ``--aead-op <mode>``
279 Set AEAD operation mode, where ``mode`` is one of
285 * ``--aead-key-sz <n>``
287 Set the size of AEAD key.

291 Set the size of AEAD iv.
293 * ``--aead-aad-sz <n>``
295 Set the size of AEAD aad.
297 * ``--digest-sz <n>``
299 Set the size of digest.
303 Set number of descriptors for each crypto device.
305 * ``--pmd-cyclecount-delay-ms <n>``
307 Add a delay (in milliseconds) between enqueue and dequeue in
308 pmd-cyclecount benchmarking mode (useful when benchmarking
309 hardware acceleration).
313 Enable test result output CSV friendly rather than human friendly.
315 * ``--pdcp-sn-sz <n>``
317 Set PDCP sequence number size(n) in bits. Valid values of n will
320 * ``--pdcp-domain <control/user>``
322 Set PDCP domain to specify short_mac/control/user plane.
324 * ``--docsis-hdr-sz <n>``
326 Set DOCSIS header size(n) in bytes.
328 * ``--pdcp-ses-hfn-en``
330 Enable fixed session based HFN instead of per packet HFN.
335 The test vector file is a text file contain information about test vectors.
336 The file is made of the sections. The first section doesn't have header.
337 It contain global information used in each test variant vectors -

459 Graph Crypto Perf Results
460 -------------------------
462 The ``dpdk-graph-crypto-perf.py`` tool is a simple script to automate
463 running crypto performance tests, and graphing the results.
464 It can be found in the ``app/test-crypto-perf/`` directory.
465 The output graphs include various grouped barcharts for throughput
466 tests, and histogram and boxplot graphs for latency tests.
467 These are output to PDF files, with one PDF per test suite graph type.
473 The following python modules must be installed to run the script:
475 .. code-block:: console
477 pip3 install img2pdf plotly pandas psutil kaleido
483 The test cases run by the script are defined by a JSON config file.
484 Some config files can be found in ``app/test-crypto-perf/configs/``,
485 or the user may create a new one following the same format as the config files provided.
487 An example of this format is shown below for one test suite in the ``crypto-perf-aesni-mb.json`` file.
488 This shows the required default config for the test suite, and one test case.
489 The test case has additional app config that will be combined with
490 the default config when running the test case.
498 "vdev": "crypto_aesni_mb"
501 "csv-friendly": true,
502 "buffer-sz": "64,128,256,512,768,1024,1408,2048",
503 "burst-sz": "1,4,8,16,32",
504 "ptest": "throughput",
505 "devtype": "crypto_aesni_mb"
508 "AES-CBC-128 SHA1-HMAC auth-then-cipher decrypt": {
509 "cipher-algo": "aes-cbc",
510 "cipher-key-sz": "16",
511 "auth-algo": "sha1-hmac",
512 "optype": "auth-then-cipher",
513 "cipher-op": "decrypt"
518 The specific test cases only allow modification of app parameters,
519 and not EAL parameters.
520 The default case is required for each test suite in the config file,
521 to specify EAL parameters.
523 Currently, crypto_qat, crypto_aesni_mb, and crypto_aesni_gcm devices for
524 both throughput and latency ptests are supported.
530 .. code-block:: console
532 ./dpdk-graph-crypto-perf <config_file>
534 The ``config_file`` positional argument is required to run the script.
535 This points to a valid JSON config file containing test suites.
537 .. code-block:: console
539 ./dpdk-graph-crypto-perf configs/crypto-perf-aesni-mb.json
541 The following are the application optional command-line options:
545 Display usage information and quit.
547 * ``-f <file_path>, --file-path <file_path>``
549 Provide path to ``dpdk-test-crypto-perf`` application.
550 The script uses the installed app by default.
552 .. code-block:: console
554 ./dpdk-graph-crypto-perf <config_file> \
555 -f <build_dir>/app/dpdk-test-crypto-perf
557 * ``-t <test_suite_list>, --test-suites <test_suite_list>``
559 Specify test suites to run. All test suites are run by default.
561 To run crypto-perf-qat latency test suite only:
563 .. code-block:: console
565 ./dpdk-graph-crypto-perf configs/crypto-perf-qat -t latency
567 To run both crypto-perf-aesni-mb throughput and latency test suites
569 .. code-block:: console
571 ./dpdk-graph-crypto-perf configs/crypto-perf-aesni-mb -t throughput latency
573 * ``-o <output_path>, --output-path <output_path>``
575 Specify directory to use for output files.
576 The default is to use the script's directory.
578 .. code-block:: console
580 ./dpdk-graph-crypto-perf <config_file> -o <output_dir>
584 Enable verbose output. This displays ``dpdk-test-crypto-perf`` app output in real-time.
586 .. code-block:: console
588 ./dpdk-graph-crypto-perf <config_file> -v
591 Latency performance tests have a large amount of output.
592 It is not recommended to use the verbose option for latency tests.
