31 dpdk-test-crypto-perf Application
32 =================================
34 The ``dpdk-test-crypto-perf`` tool is a Data Plane Development Kit (DPDK)
35 utility that allows measuring performance parameters of PMDs available in the
36 crypto tree. There are available two measurement types: throughput and latency.
37 User can use multiply cores to run tests on but only
38 one type of crypto PMD can be measured during single application
39 execution. Cipher parameters, type of device, type of operation and
40 chain mode have to be specified in the command line as application
41 parameters. These parameters are checked using device capabilities
46 On hardware devices the cycle-count doesn't always represent the actual offload
47 cost. The cycle-count only represents the offload cost when the hardware
48 accelerator is not fully loaded, when loaded the cpu cycles freed up by the
49 offload are still consumed by the test tool and included in the cycle-count.
50 These cycles are consumed by retries and inefficient API calls enqueuing and
51 dequeuing smaller bursts than specified by the cmdline parameter. This results
52 in a larger cycle-count measurement and should not be interpreted as an offload
55 On hardware devices the throughput measurement is not necessarily the maximum
56 possible for the device, e.g. it may be necessary to use multiple cores to keep
57 the hardware accelerator fully loaded and so measure maximum throughput.
59 Compiling the Application
60 -------------------------
62 **Step 1: PMD setting**
64 The ``dpdk-test-crypto-perf`` tool depends on crypto device drivers PMD which
65 are disabled by default in the build configuration file ``common_base``.
66 The crypto device drivers PMD which should be tested can be enabled by setting::
68 CONFIG_RTE_LIBRTE_PMD_<name>=y
70 Setting example for open ssl PMD::
72 CONFIG_RTE_LIBRTE_PMD_OPENSSL=y
74 **Step 2: Linearization setting**
76 It is possible linearized input segmented packets just before crypto operation
77 for devices which doesn't support scatter-gather, and allows to measure
78 performance also for this use case.
80 To set on the linearization options add below definition to the
81 ``cperf_ops.h`` file::
83 #define CPERF_LINEARIZATION_ENABLE
85 **Step 3: Build the application**
87 Execute the ``dpdk-setup.sh`` script to build the DPDK library together with the
88 ``dpdk-test-crypto-perf`` applcation.
90 Initially, the user must select a DPDK target to choose the correct target type
91 and compiler options to use when building the libraries.
92 The user must have all libraries, modules, updates and compilers installed
93 in the system prior to this,
94 as described in the earlier chapters in this Getting Started Guide.
96 Running the Application
97 -----------------------
