Release Notes
=============
#. VPP PERFORMANCE TESTS
- - CSIT test environment is versioned, see
- :ref:`test_environment_versioning`.
-
- - 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. 4 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`.
+ - **Intel Xeon Ice Lake**: Added initial test data for these
+ platforms. Current CSIT-2106 report data for Intel Xeon Ice Lake
+ comes from an external source (Intel labs running CSIT code on
+ "8360Y D Stepping" and "6338N" processors). For details about the
+ physical setup see :ref:`tested_physical_topologies`. Tested
+ VPP and CSIT versions are pre-release, VPP
+ 21.06-rc0~779-gd640ae52f.
+
+ - **MLRsearch improvements**: Added support for multiple packet
+ throughput rates in a single search, each rate is associated
+ with a distinct Packet Loss Ratio (PLR) criterion. Previously
+ only Non Drop Rate (NDR) (PLR=0) and single Partial Drop Rate
+ (PDR) (PLR<0.5%) were supported. Implemented number of
+ optimizations improving rate discovery efficiency.
+
+ - **Reduction of tests**: Removed obsolete VPP use cases and
+ superfluous test combinations from continuous and report test
+ executions, including:
+
+ - All vts tests, obsolete use cases.
+ - dot1q tests apart from dot1q-l2bd, superfluous combinations.
+ - -100flows, -100kflows in all acl tests.
+ - nat44 tests
+
+ - -pps tests, replaced by -tput tests.
+ - h1-p1-s1 single session tests, unessential combination.
+ - h4096-p63-s258048 tests, unessential scale combination.
+
+ - ipsec tests
+
+ - ethip4ipsectptlispgpe.
+ - policy-aes128gcm.
+ - policy-aes128cbc-hmac256sha.
+ - policy-aes128cbc-hmac512sha.
+ - int-aes128cbc-hmac256sha.
+ - scale of
+
+ - 400tnlsw.
+ - 5000tnlsw.
+ - 20000tnlsw.
+ - 60000tnlsw.
#. TEST FRAMEWORK
+ - **CSIT test environment** version has been updated to ver. 8, see
+ :ref:`test_environment_versioning`.
+
+ - **CSIT in AWS environment**: Added CSIT support for AWS c5n
+ instances environment.
+
- **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
- still used in CSIT for all VPP scale tests. See known issues below.
+ 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.
+ - **General Code Housekeeping**: Ongoing code optimizations and bug
+ fixes.
#. PRESENTATION AND ANALYTICS LAYER
- - **Graphs improvements**: Added possibility to use Gbps on Y-axis in
- Packet Throughput and Speedup Multi-Core graphs, added unidirectional
- mode to the Latency graphs.
+ - **Graphs improvements**: Updated Packet Latency graphs,
+ see :ref:`latency_methodology`.

| # | JiraID | Issue Description |
+====+=========================================+===========================================================================================================+
-| 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520. DPDK reporting rx-errors, indicating L1 issue. |
-| | <https://jira.fd.io/browse/CSIT-570>`_ | Suspected issue with HW combination of X710-X520 in LF testbeds. Not observed outside of LF testbeds. |
+| 1 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |
+| | <https://jira.fd.io/browse/CSIT-1782>`_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 2 | `CSIT-1763 | Adapt ramp-up phase of nat44 tests for different frame sizes. |
+| | <https://jira.fd.io/browse/CSIT-1763>`_ | Currently ramp-up phase rate and duration values are correctly set for tests with 64B frame size. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 3 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
+| | <https://jira.fd.io/browse/CSIT-1671>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
+| +-----------------------------------------+ The usual PAPI library spends too much time parsing arguments, so even with async processing (hundreds of |
+| | `VPP-1763 | commands in flight over socket), the VPP configuration for large scale tests (millions of messages) takes |
+| | <https://jira.fd.io/browse/VPP-1763>`_ | too long. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 2 | `VPP-662 | 9000B packets not supported by NICs VIC1227 and VIC1387. |
-| | <https://jira.fd.io/browse/VPP-662>`_ | |
+| 4 | `CSIT-1789 | AVF driver does not perform RSS in a deterministic way. |
+| | <https://jira.fd.io/browse/CSIT-1789>`_ | This increases standard deviation of tests with small number of flows (mainly ipsec). |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 3 | `VPP-1677 | 9000B ip4 nat44: VPP crash + coredump. |
-| | <https://jira.fd.io/browse/VPP-1677>`_ | VPP crashes very often in case that NAT44 is configured and it has to process IP4 jumbo frames (9000B). |
+| 5 | `CSIT-1790 | Broken TRex latency measurements with TRex v2.88, DPDK 21.02 and FVL FW 6.01. |
+| | <https://jira.fd.io/browse/CSIT-1790>`_ | High latency O(5msec) for all VPP and testpmd/l3fwd test cases for FVL NICs with FW 6.01. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 4 | `CSIT-1591 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
-| | <https://jira.fd.io/browse/CSIT-1499>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
-| +-----------------------------------------+ |
-| | `VPP-1763 | |
-| | <https://jira.fd.io/browse/VPP-1763>`_ | |
+| 6 | `CSIT-1780 | IPSEC SW async scheduler MRR tests failing with no traffic forwarded. |
+| | <https://jira.fd.io/browse/CSIT-1780>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 5 | `VPP-1675 | IPv4 IPSEC 9000B packet tests are failing as no packet is forwarded. |
-| | <https://jira.fd.io/browse/VPP-1675>`_ | Reason: chained buffers are not supported. |
+| 7 | `CSIT-1786 | IP4 and IP6 scale tests failing with no traffic forwarded. |
+| | <https://jira.fd.io/browse/CSIT-1786>`_ | Issue reported to VPP devs. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 6 | `CSIT-1593 | IPv4 AVF 9000B packet tests are failing on 3n-skx while passing on 2n-skx. |
-| | <https://jira.fd.io/browse/CSIT-1593>`_ | |
+| 8 | `CSIT-1785 | NAT44ED tests failing to establish all TCP sessions. |
+| | <https://jira.fd.io/browse/CSIT-1785>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 7 | `CSIT-1679 | 2n-clx VPP ip4 tests with xxv710 and avf driver are sporadically failing. |
