Release Notes ============= Changes in |csit-release| ------------------------- #. VPP PERFORMANCE TESTS - CSIT test environment is now versioned, with ver. 1 associated with CSIT rls1908 git branch as of 2019-08-21, and ver. 2 associated with CSIT rls2001 and master git branches as of 2020-03-27. - To identify performance changes due to VPP code changes from v20.01.0 to v20.05.0, both have been tested in CSIT environment ver. 2 and compared against each other. All substantial progressions has been marked up with RCA analysis. See :ref:`vpp_compare_current_vs_previous_release` and :ref:`vpp_known_issues`. #. TEST FRAMEWORK - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is still used in CSIT for all VPP scale tests. See known issues below. - **General Code Housekeeping**: Ongoing RF keywords optimizations, removal of redundant RF keywords and aligning of suite/test setup/teardowns. #. PRESENTATION AND ANALYTICS LAYER - **Graphs layout improvements**: Improved performance graphs layout for better readibility and maintenance: test grouping, axis labels, descriptions, other informative decoration. .. raw:: latex \clearpage .. _vpp_known_issues: Known Issues ------------ List of known issues in |csit-release| for VPP performance tests: +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+ | # | JiraID | Issue Description | +====+=========================================+===========================================================================================================+ | 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520. DPDK reporting rx-errors, indicating L1 issue. | | | `_ | Suspected issue with HW combination of X710-X520 in LF testbeds. Not observed outside of LF testbeds. | +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+ | 2 | `VPP-662 | 9000B packets not supported by NICs VIC1227 and VIC1387. | | | `_ | | +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+ | 3 | `CSIT-1498 | Memif tests are sporadically failing on initialization of memif connection. | | | `_ | | +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+ | 4 | `VPP-1677 | 9000B ip4 nat44: VPP crash + coredump. | | | `_ | VPP crashes very often in case that NAT44 is configured and it has to process IP4 jumbo frames (9000B). | +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+ | 5 | `CSIT-1591 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much | | | `_ | longer to program VPP). This needs to be addressed on the PAPI side. | | +-----------------------------------------+ | | | `VPP-1763 | | | | `_ | | +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+ | 6 | `VPP-1675 | IPv4 IPSEC 9000B packet tests are failing as no packet is forwarded. | | | `_ | Reason: chained buffers are not supported. | +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+ | 7 | `CSIT-1593 | IPv4 AVF 9000B packet tests are failing on 3n-skx while passing on 2n-skx. | | | `_ | | +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+ | 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).
