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
- v20.05.0 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`.
-
- - **GENEVE tests**: Added VPP performance tests for GENEVE tunnels.
-
- - See :ref:`geneve_methodology` for more details.
-
- - **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.
-
- - 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.
+ - **Intel Xeon Ice Lake**: Performance test data for these platforms
+ continues to be provided by external Intel benchmarking labs
+ executing |csit-release| tests. For details about the physical
+ setup see :ref:`tested_physical_topologies`.
- - Added new NAT44 endpoint-dependent mode CPS tests that measure
- connections per second with usage of TRex in stateful mode.
- UPD packet size is 64 bytes. Size of TCP control packets
- is not configurable, please ignore the -64b- part of test names.
+ - **AWS EC2 c5n**: Performance test data for AWS c5n instances has
+ been added to report for ip4, ip6 and ipsec tests.
- - Added new NAT44 endpoint-dependent mode PPS tests that measure
- packets per second (control and data together) with usage of TRex
- in stateful mode. UPD packet size is 64 bytes. Size of TCP
- data packets is governed by the default MSS value, so most data packets
- are 1460 bytes long, please ignore the -64b- part of test names.
-
- - See :ref:`nat44_methodology` for more details.
-
- - **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, with VPP and DPDK performance data added to CSIT
- trending and this report.
-
- - **AMD 2n-tx2 testbed**: New physical testbed type installed in
- FD.io CSIT, with VPP and DPDK performance data added to CSIT
- trending and this report.
+ - **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.
#. TEST FRAMEWORK
- - **TRex ASTF**: Added capability to run TRex in advanced stateful mode.
+ - **CSIT test environment** version has been updated to ver. 8, see
+ :ref:`test_environment_versioning`.
- - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
- still used in CSIT for all VPP scale tests. See known issues below.
+ - **CSIT in AWS environment**: Completed CSIT automation support for
+ AWS c5n instances environment, including weekly performance
+ trending tests execution.
- - **General Code Housekeeping**: Ongoing RF keywords optimizations,
- removal of redundant RF keywords and aligning of suite/test
- setup/teardowns.
+ - **CSIT PAPI support**: Due to issues with PAPI performance, and
+ deprecation of VAT, CLI is used in CSIT for many VPP scale tests.
+ See known issues below.
- - **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 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. |
-| | <https://jira.fd.io/browse/CSIT-570>`_ | 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. |
-| | <https://jira.fd.io/browse/VPP-662>`_ | |
+| 1 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. The issue persists after FVL FW upgrade. |
+| | <https://jira.fd.io/browse/CSIT-1782>`_ | |

-| 3 | `CSIT-1763 | Adapt ramp-up phase of nat44 tests for different frame sizes. |
+| 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. |

-| 4 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
+| 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. |
+| 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-1780 | IPSEC SW async scheduler MRR tests failing with no traffic forwarded. |
+| | <https://jira.fd.io/browse/CSIT-1780>`_ | |

+| 6 | `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 | `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. |
+| 7 | `CSIT-1785 | NAT44ED tests failing to establish all TCP sessions. |
+| | <https://jira.fd.io/browse/CSIT-1785>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 7 | `CSIT-1760 | All Mellanox / rdma driver tests are failing on LF testbed28 while successfully run on other LF testbeds. |
-| | <https://jira.fd.io/browse/CSIT-1760>`_ | |
+| 8 | `CSIT-1791 | Performance regression in RDMA tests, due to CSIT environment changes. |
