Release Notes
=============
- CSIT test environment is versioned, see
:ref:`test_environment_versioning`.
- - To identify performance changes due to VPP code changes from
- v20.05.0 to v20.09.0, both have been tested in CSIT environment
- ver. 5 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`.
-
- - **NAT44 tests**: Adapted existing and added new tests.
-
- - Refactored NAT44 deterministic mode (nat44det) tests to use separate
- det44 vpp plugin and to use the same scheme of inside and outside
- addresses and ports, as used in new NAT44 endpoint-dependent mode tests.
+ - **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.
- - Added new NAT44 endpoint-depended mode uni-directional (nat44ed-udir)
- tests that measure packet throughput in one direction with usage of TRex
- in stateless mode.
+ - Initial test data for Intel Xeon Ice Lake 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 detail about the physical setup
+ see :ref:`tested_physical_topologies`. Tested VPP and CSIT
+ versions are pre-release, VPP 21.06-rc0~779-gd640ae52f.
- - Added new NAT44 endpoint-dependent mode CPS tests that measure
- connections per second with usage of TRex in stateful mode.
- See updated methodology sections for more details.
+ - **AF_XDP**: Added af_xdp driver testing for all testcases.
- - Added new NAT44 endpoint-dependent mode PPS tests that measure
- packets per second (protocol and data together) with usage of TRex
- in stateful mode. See updated methodology sections for more details.
+ - **GTPU tunnel**: Added GTPU HW Offload IPv4 routing tests.
- - **IPSec async mode tests**: Added VPP performance tests for async crypto
- engine.
-
- - **AMD 2n-zn2 testbed**: New physical testbed type installed in FD.io CSIT,
- VPP performance data will be added in upcoming weeks.
+ - **Telemetry retouch**: Redesign telemetry retrieval from DUT.
+ Include VPP perfmon plugin telemetry.
#. TEST FRAMEWORK
- - **TRex ASTF**: Added capability to run TRex in advanced stateful mode.
-
- **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.
-
- - **Intel E810CQ 100G NIC**: Added configuration for Intel E810CQ 100G NIC.
- No tests run for this NIC as it is not present in FD.io CSIT lab yet.
+ - **General Code Housekeeping**: Ongoing code optimizations,
+ speed ups 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`.

-| 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520. DPDK reporting rx-errors, indicating L1 issue. |

+| 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. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 5 | `CSIT-1771 | IPv4 IPSEC 9000B packet tests had been failing when chained buffers were not supported. |
-| | <https://jira.fd.io/browse/CSIT-1771>`_ | This has been fixed on VPP side, but CSIT still needs to re-enable jumbo tests. |
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 6 | `VPP-1934 | [i40e] Interfaces are not brought up from carrier-down. |
-| | <https://jira.fd.io/browse/VPP-1934>`_ | In case of i40e -based interface (e.g Intel x700 series NIC) is bound to kernel driver (i40e) and is in |
-| | | state "no-carrier" (<NO-CARRIER,BROADCAST,MULTICAST,UP>) because previously it was disabled via |
-| | | "I40E_AQ_PHY_LINK_ENABLED" call, then VPP during initialization of AVF interface is not re-enabling |
-| | | interface link via i40e driver to up. |
-| | | CSIT implemented `workaround for AVF interface <https://gerrit.fd.io/r/c/csit/+/29086>`_ until fixed. |
