Release Notes
=============
Changes in |csit-release|
-------------------------
-#. **VPP Performance Tests**
+#. VPP PERFORMANCE TESTS
- - **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
- and for comparison between VPP releases.
+ - **Added new performance testbed 3n-snr** (3 Node SnowRidge, with Intel
+ Atom processors), to later replace 3n-dnv and 2n-dnv (3 and 2 Node
+ Denverton) testbeds.
- - **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.
+ - **Added GTPU HW offload tests** for Intel e810 4p25ge NICs on 2n-icx
+ testbeds.
- - **L2patch Tests**: Tests measure performance of VPP L2patch, the
- fastest L2 forwarding path implemented in VPP, that cross-links
- RX and TX of two physical interfaces.
+ - **Reduction of tests**: Removed certain test variations executed
+ iteratively for the report (as well as in daily and weekly
+ trending) due to physical testbeds overload.
- - **2-Node Tests**: A new baseline set of 2-node tests covering base
- ip4, ip6, l2patch, l2bd, l2xc, running on new Xeon Skylake
- testbeds.
+#. TEST FRAMEWORK
+
+ - **CSIT test environment** version has been updated to ver. 11, see
+ :ref:`test_environment_versioning`.
+
+ - **TCP tput profiles** have to be changed, as newer TRex versions
+ are not deterministic enough when deciding when to send an ACK.
- - **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.
+ - **CSIT PAPI support**: Due to issues with PAPI performance, and
+ deprecation of VAT, VPP CLI is used in CSIT for many VPP scale
+ tests. See :ref:`vpp_known_issues`.
- - **Simultaneous Multi-Threading**: SMT-aware detection of server
- processor operation mode (HyperThreading enabled/disabled) with
- associated compute resource configuration including thread
- affinity, number of Rx queues and DPDK I/O mbufs. Tests are
- automatically tagged during execution to indicate executed thread
- configuration.
+ - **General Code Housekeeping**: Ongoing code optimizations and bug
+ fixes.
- - **Intel Xeon Skylake Support**: Support for 2-Node and 3-Node
- physical testbed topologies based on the new SuperMirco servers
- each with two Intel Xeon Skylake Platinum processors. Full
- Ansible playbooks refactor for quick server (re)installation and
- reference pointers of configuration.
+#. PRESENTATION AND ANALYTICS LAYER
-#. **Presentation and Analytics Layer**
+ - **`C-Dash `** performance dashboard got updated UI and
+ updated backend increasing its performance and robustness.
- - **Performance trending**: Further improved continuous performance
- trending with anomaly detection and analysis.
+.. raw:: latex
-#. **Test Framework Optimizations**
+ \clearpage
- - **General Code Housekeeping**: Ongoing RF keywords optimizations,
- removal of redundant RF keywords.

+| # | JiraID | Issue Description |
++====+=========================================+===========================================================================================================+
+| 1 | `CSIT-1671 | 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. |
+| +-----------------------------------------+ Currently, the time critical code uses VAT running large files with exec statements and CLI commands. |
+| | `VPP-1763 | Still, we needed to reduce the number of scale tests run to keep overall duration reasonable. |
+| | `_ | More improvements needed to achieve sufficient configuration speed. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 2 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |
+| | `_ | Frequency is reduced by CSIT workaround, but occasional failures do still happen. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 3 | `CSIT-1785 | NAT44ED tests failing to establish all TCP sessions. |
+| | `_ | At least for max scale, in allotted time (limited by session 500s timeout) due to worse |
+| +-----------------------------------------+ slow path performance than previously measured and calibrated for. |
+| | `VPP-1972 | CSIT removed the max scale NAT tests to avoid this issue. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 4 | `CSIT-1799 | All NAT44-ED 16M scale tests fail while setting NAT44 address range. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 5 | `CSIT-1800 | All Geneve L3 mode scale tests (1024 tunnels) are failing. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 6 | `CSIT-1801 | 9000B payload frames not forwarded over tunnels due to violating supported Max Frame Size (VxLAN, LISP, |
+| | `_ | SRv6). |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 7 | `CSIT-1802 | AF-XDP - NDR tests failing from time to time. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 8 | `CSIT-1803 | 3n-icx testbeds (Icelake): all IMIX aes128cbc-hmac512sha tests are failing due to excessive packet loss. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 9 | `CSIT-1804 | 3n-tsh, 3n-alt testbed (Taishan, Altra): NDR tests failing from time to time. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 10 | `CSIT-1808 | All tests with 9000B payload frames not forwarded over memif interfaces. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 11 | `CSIT-1809 | All tests with 9000B payload frames not forwarded over vhostuser interfaces. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 12 | `CSIT-1812 | All IMIX NAT44DET 4m 16m scale tests fail due to not creating required session count. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 13 | `CSIT-1827 | 3n-icx, 3n-skx: all AVF crypto tests sporadically fail. 1518B with no traffic, IMIX with excessive |
+| | `_ | packet loss. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 14 | `CSIT-1830 | All testbeds: All TCP tput (and pps) tests are failing for small packets. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 15 | `CSIT-1832 | 3n-alt: NDR 1 packet lost on random tests. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 16 | `CSIT-1834 | 2n-icx, 2n-skx: sporadic AVF soak tests failing to find critical load with PLRsearch. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 17 | `CSIT-1847 | 2n-skx: all 10vm-1t test failed with half of packets dropped. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
