Release Notes
=============
@@ -6,32 +8,40 @@ Changes in |csit-release|
#. 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.
+ - **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.
- - **AF_XDP**: Added af_xdp driver testing for all testcases.
+ - **Added GTPU HW offload tests** for Intel e810 4p25ge NICs on 2n-icx
+ testbeds.
- - **GTPU tunnel**: Added GTPU HW Offload IPv4 routing tests.
+ - **Added Wireguard tests** for VPP software path (3n-icx, 3n-snr
+ testbeds) and with built-in HW crypto QAT device (3n-snr testbed
+ only).
- - **Telemetry retouch**: Redesign telemetry retrieval from DUT. Include
- VPP perfmon plugin telemetry.
+ - **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
- - **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 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.
- - **General Code Housekeeping**: Ongoing code optimizations,
- speed ups and bug fixes.
+ - **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`.
+
+ - **General Code Housekeeping**: Ongoing code optimizations and bug
+ fixes.
#. PRESENTATION AND ANALYTICS LAYER
- - **Graphs improvements**: Updated Packet Latency graphs,
- see :ref:`latency_methodology`.
+ - **C-Dash** `performance dashboard `_ got updated UI and
+ updated backend increasing its performance and robustness.

-| 3 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |

-| +-----------------------------------------+ The usual PAPI library spends too much time parsing arguments, so even with async processing (hundreds of |

-| 1 | `VPP-1972 | One VPP change has decreased performance of NAT44ed processing, both slow path and fast path. |
+| 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-1804 | All testbeds: NDR tests failing from time to time. |

++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 10 | `CSIT-1827 | 3n-icx, 3n-skx: all AVF crypto tests sporadically fail. 1518B with no traffic, IMIX with excessive |
+| | `_ | packet loss. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+

+| 1 | `CSIT-1834 | 2n-icx, 2n-skx: sporadic AVF soak tests failing to find critical load with PLRsearch. |

++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 2 | `CSIT-1846 | 2n-skx, 2n-clx, 2n-icx: ALL 1518B TCP tput tests failing with big packet loss. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 3 | `CSIT-1851 | trending regression: various icelake tests around 2202-04-15 |
+| | `_ | Somewhat expected consequence of a VPP usability fix, |
+| | | the previous VPP compiler version was too new for the OS used. |

+| # | JiraID | Issue Description |
++====+=========================================+=====================================================================================+
+| 1 | `VPP-2030 | regression: ip6base on ICX around 2022-03-23 |
+| | `_ | "Loads blocked due to overlapping with a preceding store that cannot be forwarded." |
+| | | started happening in ip6-lookup graph node. |
++----+-----------------------------------------+-------------------------------------------------------------------------------------+
+| 2 | `CSIT-1852 | 2n-zn2 mellanox performance cap |
+| | `_ | Old issue, only now distinguished from CSIT-1751. |
+| | | This testbed+nic combination is capped below 28 Mpps, cause not identified yet. |
++----+-----------------------------------------+-------------------------------------------------------------------------------------+
+| 3 | `CSIT-1853 | trending regression: nat44ed cps around 2202-04-01 |
+| | `_ | VPP change added more computation to slow path (in order to support multiple VRFs). |
+| | | Not clear if the VPP implementation is optimized enough. |
