-CSIT Release Notes\r
-==================\r
-\r
-Changes in CSIT |release|\r
--------------------------\r
-\r
-#. Test environment changes in VPP data plane performance tests:\r
-\r
- - Further characterization and optimizations of VPP vhost-user and VM\r
- test methodology and test environment;\r
-\r
- - Tests with varying Qemu virtio queue (a.k.a. vring) sizes:\r
- [vr256] default 256 descriptors, [vr1024] 1024 descriptors to\r
- optimize for packet throughput;\r
-\r
- - Tests with varying Linux CFS (Completely Fair Scheduler)\r
- settings: [cfs] default settings, [cfsrr1] CFS RoundRobin(1)\r
- policy applied to all data plane threads handling test packet\r
- path including all VPP worker threads and all Qemu testpmd\r
- poll-mode threads;\r
-\r
- - Resulting test cases are all combinations with [vr256,vr1024] and\r
- [cfs,cfsrr1] settings;\r
-\r
- - For more detail see performance results observations section in\r
- this report;\r
-\r
-#. Code updates and optimizations in CSIT performance framework:\r
-\r
- - Complete CSIT framework code revision and optimizations as descried\r
- on CSIT wiki page\r
- `Design_Optimizations <https://wiki.fd.io/view/CSIT/Design_Optimizations>`_.\r
-\r
- - For more detail see the CSIT Framework Design section in this\r
- report;\r
-\r
-#. Changes to CSIT driver for TRex Traffic Generator:\r
-\r
- - Complete refactor of TRex CSIT driver;\r
-\r
- - Introduction of packet traffic profiles to improve usability and\r
- manageability of traffic profiles for a growing number of test\r
- scenarios.\r
-\r
- - Support for packet traffic profiles to test IPv4/IPv6 stateful and\r
- stateless DUT data plane features;\r
-\r
-#. Added VPP performance tests\r
-\r
- - **Linux Container VPP memif virtual interface tests**\r
-\r
- - VPP Memif virtual interface (shared memory interface) tests\r
- interconnecting VPP instances over memif. VPP vswitch\r
- instance runs in bare-metal user-mode handling Intel x520 NIC\r
- 10GbE interfaces and connecting over memif (Master side) virtual\r
- interfaces to another instance of VPP running in bare-metal Linux\r
- Container (LXC) with memif virtual interfaces (Slave side). LXC\r
- runs in a priviliged mode with VPP data plane worker threads\r
- pinned to dedicated physical CPU cores per usual CSIT practice.\r
- Both VPP run the same version of software. This test topology is\r
- equivalent to existing tests with vhost-user and VMs.\r
-\r
- - **Stateful Security Groups**\r
-\r
- - New tests of VPP stateful security-groups a.k.a. acl-plugin\r
- functionally compatible with networking-vpp OpenStack;\r
-\r
- - New tested security-groups access-control-lists (acl)\r
- configuration variants include: [iaclNsl] input acl stateless,\r
- [oaclNsl] output acl stateless, [iaclNsf] input acl stateful\r
- a.k.a. reflect, [oaclNsf] output acl stateful a.k.a. reflect,\r
- where N is number of access-control-entries (ace) in the acl.\r
-\r
- - Testing packet flows transmitted by TG: 100, 10k, 100k, always\r
- hitting the last permit entry in acl.\r
-\r
- - **VPP vhost and VM tests**\r
-\r
- - New VPP vhost-user and VM test cases to benchmark performance of\r
- VPP and VM topologies with Qemu and CFS policy combinations of\r
- [vr256,vr1024] x [cfs,cfsrr1];\r
-\r
- - Statistical analysis of repeatibility of results;\r
-\r

+Release Notes
+=============
+
+Changes in |csit-release|
+-------------------------
+
+#. VPP PERFORMANCE TESTS
+
+ - **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.
+
+ - **Added GTPU HW offload tests** for Intel e810 4p25ge NICs on 2n-icx
+ testbeds.
+
+ - **Added Wireguard tests** for VPP software path (3n-icx, 3n-snr
+ testbeds) and with built-in HW crypto QAT device (3n-snr testbed
+ only).
+
+ - **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 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.
+
+ - **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
+
+ - **C-Dash** `performance dashboard <http://csit.fd.io/>`_ got updated UI and
+ updated backend increasing its performance and robustness.

++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| # | JiraID | Issue Description |
++====+=========================================+===========================================================================================================+
+| 1 | `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. |
+| +-----------------------------------------+ 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. |
+| | <https://jira.fd.io/browse/VPP-1763>`_ | More improvements needed to achieve sufficient configuration speed. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 2 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |
+| | <https://jira.fd.io/browse/CSIT-1782>`_ | Frequency is reduced by CSIT workaround, but occasional failures do still happen. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 3 | `CSIT-1785 | NAT44ED tests failing to establish all TCP sessions. |
+| | <https://jira.fd.io/browse/CSIT-1785>`_ | 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. |
+| | <https://jira.fd.io/browse/VPP-1972>`_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 4 | `CSIT-1799 | All NAT44-ED 16M scale tests fail while setting NAT44 address range. |
+| | <https://jira.fd.io/browse/CSIT-1799>`_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 5 | `CSIT-1800 | All Geneve L3 mode scale tests (1024 tunnels) are failing. |
+| | <https://jira.fd.io/browse/CSIT-1800>`_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 6 | `CSIT-1801 | 9000B payload frames not forwarded over tunnels due to violating supported Max Frame Size (VxLAN, LISP, |
+| | <https://jira.fd.io/browse/CSIT-1801>`_ | SRv6). |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+

+| 10 | `CSIT-1827 | 3n-icx, 3n-skx: all AVF crypto tests sporadically fail. 1518B with no traffic, IMIX with excessive |
+| | <https://jira.fd.io/browse/CSIT-1827>`_ | packet loss. |
