Release Notes
=============
#. VPP PERFORMANCE TESTS
- - CSIT test environment is versioned, see
- :ref:`test_environment_versioning`.
-
- - **Upgrade to Ubuntu 20.04 LTS**: Reinstall base operating system to Ubuntu
- 20.04.2 LTS. Upgrade includes also baseline Docker containers used for
- spawning topology.
-
- - **AF_XDP**: Added af_xdp driver testing for all testcases.
+ - **AF_XDP**: Added af_xdp driver support for all test cases. Test
+ results will be added in sub-sequent CSIT-2106 report.
- **GTPU tunnel**: Added GTPU HW Offload IPv4 routing tests.
- - **Telemetry retouch**: Redesign telemetry retrieval from DUT. Include
- VPP perfmon plugin telemetry.
+ - **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
+ - **Telemetry retouch**: Refactored telemetry retrieval from DUTs and
+ SUTs. Included VPP perfmon plugin telemetry with all perfmon
+ bundles available in VPP release.
+
+ - **Upgrade to Ubuntu 20.04 LTS**: Re-installed base operating system
+ to Ubuntu 20.04.2 LTS. Upgrade included also baseline Docker
+ containers used for spawning topology.
+
+ - **TRex upgrade v2.86 to v2.88**: Included move to DPDK 21.02 and
+ changed the way egress low latency queues are used in FVL NICs.
+ This broke latency measurements for majority of FVL NICs in
+ CSIT. Latency values look better after upgrading FVL FW on TRex
+ servers, but still somewhat higher than before the TRex upgrade.
+ Tracked by `CSIT-1790 <https://jira.fd.io/browse/CSIT-1790>`_.
+
+ - **CSIT test environment** version has been updated to ver. 7, see
+ :ref:`test_environment_versioning`.
+
+ - **CSIT in AWS environment**: Added CSIT support for AWS c5n
+ instances environment. Test results will be added in sub-sequent
+ CSIT-2106 report.
+
- **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 code optimizations,
- speed ups and bug fixes.

| # | JiraID | Issue Description |

-| 1 | `VPP-662 | 9000B packets not supported by NICs VIC1227 and VIC1387. |
-| | <https://jira.fd.io/browse/VPP-662>`_ | |
+| 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. |
| | `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. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 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). |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 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. |
