Release Notes
=============
@@ -6,61 +8,46 @@ Changes in |csit-release|
#. VPP PERFORMANCE TESTS
- - **Service density 2n-skx tests**: Added higher NF density tests with
- 802.1q (vlan) and VXLAN encapsulation from Traffic Generator.
-
- - **GBP tests**: Added GBP (Group Based Policy) routing test cases
- with 802.1q (vlan) external traffic.
-
- - **AVF IPv4 scale tests**: Increased coverage of AVF IPv4 base and
- scale test cases (Fortville NICs only).
-
- - **2n-skx tests**: Increased coverage of selected (COP, iACL,
- Policer) test cases.
+ - **Enhanced and added VPP hoststack tests** to daily and weekly
+ trending including: Quic VPP Echo, UDP+TCP LD_PRELOAD iPerf3,
+ LD_PRELOAD NGINX.
- - **IPsec scale tests**: Added IPsec interface mode scale tests with
- 1, 40, 400, 1000, 5000, 10000, 20000, 40000, 60000 IPsec tunnels.
- Removed DPDK backend dependency. Major IPsec test code
- refactoring.
+ - **Added Nvidia/Mellanox DPDK tests** to daily and weekly trending
+ and report, in addition to RDMA_CORE ones that were already
+ there.
- - **Hoststack TCP/IP tests**: Major refactor of Hoststack TCP
- performance tests using WRK generator talking to the VPP HTTP
- static server plugin measuring connections per second and
- requests per second.
+ - **Jumbo frames tests** got fixed and re-added number of to report
+ coverage tests.
- - **Changed methodology of dot1q tests in 2-Node testbeds**: dot1q
- encapsulation is now used on both links of SUT. Previously dot1q
- was used only on a single link with the other link carrying
- untagged Ethernet frames. This change results in slightly lower
- throughput in CSIT-1908 for all dot1q tests in all 2-Node
- testbeds.
-
- - **KVM VM vhost-user tests**: completed move to Kernel-VM for all
- tests. In addition to running DPDK Testpmd as VM workload, new
- tests created with VPP as VM workload. VPP in VM is the same
- version as the DUT VPP (acting as vSwitch) and its configuration
- depends on the test type. For all L2 Ethernet Switching tests
- it's vpp-l2xc (L2 cross-connect), for all IPv4 Routing tests it's
- vpp-ip4 (VPP IPv4 routing).
+ - **Intel Xeon SKX performance testbeds** got decommissioned and
+ removed from FD.io performance lab.
#. TEST FRAMEWORK
- - **CSIT PAPI Support**: Finished conversion of CSIT VAT L1 keywords
- to PAPI L1 KWs in CSIT using VPP Python bindings (VPP PAPI).
- Redesign of key components of PAPI Socket Executor and PAPI
- history. 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 not changed from ver. 11 used
+ in previous release, see :ref:`test_environment_versioning`.
- - **General Code Housekeeping**: Ongoing RF keywords optimizations,
- removal of redundant RF keywords and aligning of suite/test
- setup/teardowns.
+ - **CSIT PAPI optimizations for scale** got applied improving PAPI
+ programming speed especially for large scale tests. VAT has been
+ now completely deprecated from CSIT.
+ - **General Code Housekeeping**: Ongoing code optimizations and bug
+ fixes.
#. PRESENTATION AND ANALYTICS LAYER
- - **Graphs Layout Improvements**: Improved performance graphs layout
- for better readibility and maintenance: test grouping, axis
- labels, descriptions, other informative decoration.
+ - `Performance dashboard `_ got updated with
+ addition of VPP telemetry trending across all VPP tests. A number
+ of code and AWS resource usage optimizations got applied to the
+ data processing pipeline and UI frontend and backend.
+
+ - Examples of release iterative data visualisation:
+
+ - `Packet throughput 2n-icx-e810cq-ip4-base-scale-pdr `_
+ - `Speedup Multi-Core throughput graph for 2n-icx-e810cq-ip4-base-pdr `_
+ - `MRR, NDR and PDR comparison for 2n-icx-e810cq-ip4-base `_
+ - `Normalized throughput architecture comparison for 2n-[icx|clx]-e810cq-ip4-base-pdr `_
+ - `NICs comparison for 2n-icx-ip4-base-pdr `_

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

-| 3 | `CSIT-1503 | [`TRex-519 `_] XL710/XXV710 with FW 6.0.1 will have |

-| 6 | `VPP-1676 | 9000B ip4 memif errors - ip4-input: ip4 length > l2 length. |
-| | `_ | IP4 jumbo frames (9000B) are dropped in case of tests with memif. |

-| 7 | `VPP-1677 | 9000B ip4 nat44: VPP crash + coredump. |
-| | `_ | VPP crashes very often in case that NAT44 is configured and it has to process IP4 jumbo frames (9000B). |
-+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
-| 8 | `CSIT-1591 | 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. |
-| | | |
-| | `VPP-1763 | |
-| | `_ | |
-+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
-| 9 | `CSIT-1592 | VPP memif API does not enable memif zero-copy, resulting in different memif configuration vs. previously |
-| | `_ | tested VAT/CLI where memif zero-copy was enabled by default. Needs to be fixed in VPP. |
