See :ref:`dpdk_known_issues`. -#. **DPDK performance tests** +#. DPDK RELEASE VERSION CHANGE - - **MRR Throughput**: MRR (Maximum Receive Rate) test code has now - configurable trial duration and number of consecutive executions. - Coverage of MRR tests has been extended across more test - scenarios. MRR tests are used for continuous performance trending. + - |csit-release| tested |dpdk-release|, as used by |vpp-release|. - - **MLRsearch Throughput**: MLRsearch algorithm has been introduced - for all NDR and PDR throughput tests. All tests that previously - used binary search got converted to MLRsearch. Coverage of NDR/PDR - tests has been extended across more test scenarios. - - - **2-Node Tests**: A new set of 2-node tests covering DPDK Testpmd - and L3fwd, running on new Xeon Skylake testbeds. - - - **More NICs**: Increased coverage of NIC models tested: Intel- - xxv710-da2, Intel-x710-da4. - - - **Generated tests**: Simplified and unified test structure, semi- - autogenerated by generator script. Test generator is currently - able to create test combinations with various frame size and - cores combinations. All existing test cases were converted to new - format. - -#. **Presentation and Analytics Layer** - - - **Performance trending**: Added continuous performance trending with - anomaly detection and analysis for DPDK. +.. _dpdk_known_issues: Known Issues ------------ -No known issues. +List of known issues in |csit-release| for DPDK performance tests: + ++----+------------------------------------------+----------------------------------------------------------------------------------------------------------+ +| # | JiraID | Issue Description | ++====+==========================================+==========================================================================================================+ +| 8 | `CSIT-1675 | Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds behaviour and performance became inconsistent following | +| | `_ | the upgrade to the latest Ubuntu 18.04 LTS kernel version (4.15.0-72-generic) and associated microcode | +| | | packages (skx ucode 0x2000064, clx ucode 0x500002c).
