Tests +can be used for verification of performance and correct functionality of upcoming DPDK +and OVS releases and release candidates. + +These tests are part of integration testcases and they must be executed with +``--integration`` CLI parameter. + +Example of execution of all OVS/DPDK regression tests: + +.. code-block:: bash + + $ ./vsperf --integration --tests ovsdpdk_ + +Testcases are defined in the file ``conf/integration/01b_dpdk_regression_tests.conf``. This file +contains a set of configuration options with prefix ``OVSDPDK_``. These parameters can be used +for customization of regression tests and they will override some of standard VSPERF configuration +options. It is recommended to check OVSDPDK configuration parameters and modify them in accordance +with VSPERF configuration. + +At least following parameters should be examined. Their values shall ensure, that DPDK and +QEMU threads are pinned to cpu cores of the same NUMA slot, where tested NICs are connected. + +.. code-block:: python + + _OVSDPDK_1st_PMD_CORE + _OVSDPDK_2nd_PMD_CORE + _OVSDPDK_GUEST_5_CORES + +DPDK NIC Support +++++++++++++++++ + +A set of performance tests to verify support of DPDK accelerated network interface cards. +Testcases use standard physical to physical network scenario with several vSwitch and +traffic configurations, which includes one and two PMD threads, uni and bidirectional traffic +and RFC2544 Continuous or RFC2544 Throughput with 0% packet loss traffic types. + +======================================== ====================================================================================== +Testcase Name Description +======================================== ====================================================================================== +ovsdpdk_nic_p2p_single_pmd_unidir_cont P2P with single PMD in OVS and unidirectional traffic. +ovsdpdk_nic_p2p_single_pmd_bidir_cont P2P with single PMD in OVS and bidirectional traffic. +ovsdpdk_nic_p2p_two_pmd_bidir_cont P2P with two PMDs in OVS and bidirectional traffic. +ovsdpdk_nic_p2p_single_pmd_unidir_tput P2P with single PMD in OVS and unidirectional traffic. +ovsdpdk_nic_p2p_single_pmd_bidir_tput P2P with single PMD in OVS and bidirectional traffic. +ovsdpdk_nic_p2p_two_pmd_bidir_tput P2P with two PMDs in OVS and bidirectional traffic. +======================================== ====================================================================================== + +DPDK Hotplug Support +++++++++++++++++++++ + +A set of functional tests to verify DPDK hotplug support. Tests verify, that it is possible +to use port, which was not bound to DPDK driver during vSwitch startup. There is also +a test which verifies a possibility to detach port from DPDK driver. However support +for manual detachment of a port from DPDK has been removed from recent OVS versions and +thus this testcase is expected to fail. + +======================================== ====================================================================================== +Testcase Name Description +======================================== ====================================================================================== +ovsdpdk_hotplug_attach Ensure successful port-add after binding a device to igb_uio after + ovs-vswitchd is launched. +ovsdpdk_hotplug_detach Same as ovsdpdk_hotplug_attach, but delete and detach the device + after the hotplug. Note Support of netdev-dpdk/detach has been + removed from OVS, so testcase will fail with recent OVS/DPDK + versions. +======================================== ====================================================================================== + +RX Checksum Support ++++++++++++++++++++ + +A set of functional tests for verification of RX checksum calculation for tunneled traffic. +Open vSwitch enables RX checksum offloading by default if NIC supports it. It is to note, +that it is not possible to disable or enable RX checksum offloading. In order to verify +correct RX checksum calculation in software, user has to execute these testcases +at NIC without HW offloading capabilities. + +Testcases utilize existing overlay physical to physical (op2p) network deployment +implemented in vsperf. This deployment expects, that traffic generator sends unidirectional +tunneled traffic (e.g. vxlan) and Open vSwitch performs data decapsulation and sends them +back to the traffic generator via second port. + +======================================== ====================================================================================== +Testcase Name Description +======================================== ====================================================================================== +ovsdpdk_checksum_l3 Test verifies RX IP header checksum (offloading) validation for + tunneling protocols. +ovsdpdk_checksum_l4 Test verifies RX UDP header checksum (offloading) validation for + tunneling protocols. +======================================== ====================================================================================== + +Flow Control Support +++++++++++++++++++++ + +A set of functional testcases for the validation of flow control support in Open vSwitch +with DPDK support. If flow control is enabled in both OVS and Traffic Generator, +the network endpoint (OVS or TGEN) is not able to process incoming data and +thus it detects a RX buffer overflow. It then sends an ethernet pause frame (as defined at 802.3x) +to the TX side. This mechanism will ensure, that the TX side will slow down traffic transmission +and thus no data is lost at RX side. + +Introduced testcases use physical to physical scenario to forward data between +traffic generator ports. It is expected that the processing of small frames in OVS is slower +than line rate. It means that with flow control disabled, traffic generator will +report a frame loss. On the other hand with flow control enabled, there should be 0% +frame loss reported by traffic generator. + +======================================== ====================================================================================== +Testcase Name Description +======================================== ====================================================================================== +ovsdpdk_flow_ctrl_rx Test the rx flow control functionality of DPDK PHY ports. +ovsdpdk_flow_ctrl_rx_dynamic Change the rx flow control support at run time and ensure the system + honored the changes. +======================================== ====================================================================================== + +Multiqueue Support +++++++++++++++++++ + +A set of functional testcases for validation of multiqueue support for both physical +and vHost User DPDK ports.
