Pablo de Lara 083de3eba7 app/crypto-perf: parse segment size
Instead of parsing number of segments, from the command line,
parse segment size, as it is a more usual case to have
the segment size fixed and then different packet sizes
will require different number of segments.

dpdk-test-crypto-perf Application
=================================
The ``dpdk-test-crypto-perf`` tool is a Data Plane Development Kit (DPDK)
utility that allows measuring performance parameters of PMDs available in the
crypto tree. There are available two measurement types: throughput and latency.
User can use multiply cores to run tests on but only
one type of crypto PMD can be measured during single application
execution. Cipher parameters, type of device, type of operation and
chain mode have to be specified in the command line as application
parameters. These parameters are checked using device capabilities
structure.
Limitations
-----------
On hardware devices the cycle-count doesn't always represent the actual offload
cost. The cycle-count only represents the offload cost when the hardware
accelerator is not fully loaded, when loaded the cpu cycles freed up by the
offload are still consumed by the test tool and included in the cycle-count.
These cycles are consumed by retries and inefficient API calls enqueuing and
dequeuing smaller bursts than specified by the cmdline parameter. This results
in a larger cycle-count measurement and should not be interpreted as an offload
cost measurement. Using "pmd-cyclecount" mode will give a better idea of
actual costs of hardware acceleration.
On hardware devices the throughput measurement is not necessarily the maximum
possible for the device, e.g. it may be necessary to use multiple cores to keep
the hardware accelerator fully loaded and so measure maximum throughput.
Compiling the Application
-------------------------
**Step 1: PMD setting**
The ``dpdk-test-crypto-perf`` tool depends on crypto device drivers PMD which
are disabled by default in the build configuration file ``common_base``.
The crypto device drivers PMD which should be tested can be enabled by setting::
CONFIG_RTE_LIBRTE_PMD_<name>=y
Setting example for open ssl PMD::
CONFIG_RTE_LIBRTE_PMD_OPENSSL=y
**Step 2: Linearization setting**
It is possible linearized input segmented packets just before crypto operation
for devices which doesn't support scatter-gather, and allows to measure
performance also for this use case.
To set on the linearization options add below definition to the
``cperf_ops.h`` file::
#define CPERF_LINEARIZATION_ENABLE
**Step 3: Build the application**
Execute the ``dpdk-setup.sh`` script to build the DPDK library together with the
``dpdk-test-crypto-perf`` applcation.
Initially, the user must select a DPDK target to choose the correct target type
and compiler options to use when building the libraries.
The user must have all libraries, modules, updates and compilers installed
in the system prior to this,
as described in the earlier chapters in this Getting Started Guide.
Running the Application
-----------------------
The tool application has a number of command line options:
.. code-block:: console
dpdk-test-crypto-perf [EAL Options] -- [Application Options]
EAL Options
~~~~~~~~~~~
The following are the EAL command-line options that can be used in conjunction
with the ``dpdk-test-crypto-perf`` applcation.
See the DPDK Getting Started Guides for more information on these options.

Set the size of single packet (plaintext or ciphertext in it).
This can be set as:
* Single value (i.e. ``--buffer-sz 16``)

where ``min`` is minimum size, ``inc`` is the increment size and ``max``
is the maximum size (i.e. ``--buffer-sz 16:2:32``)
* List of values, up to 32 values, separated in commas (i.e. ``--buffer-sz 32,64,128``)
* ``--segment-sz <n>``

Test Vector File
~~~~~~~~~~~~~~~~
The test vector file is a text file contain information about test vectors.
The file is made of the sections. The first section doesn't have header.
It contain global information used in each test variant vectors -
typically information about plaintext, ciphertext, cipher key, aut key,
initial vector. All other sections begin header.
The sections contain particular information typically digest.
**Format of the file:**
Each line beginig with sign '#' contain comment and it is ignored by parser::
# <comment>
Header line is just name in square bracket::
[<section name>]
Data line contain information tocken then sign '=' and
a string of bytes in C byte array format::
<tocken> = <C byte array>
**Tockens list:**
* ``plaintext``
Original plaintext to be crypted.
* ``ciphertext``
Encrypted plaintext string.
* ``cipher_key``
Key used in cipher operation.
* ``auth_key``
Key used in auth operation.
* ``cipher_iv``
Cipher Initial Vector.
* ``auth_iv``
Auth Initial Vector.
* ``aad``
Additional data.
* ``digest``
Digest string.
