Release Notes
=============
Changes in |csit-release|
-------------------------
#. VPP PERFORMANCE TESTS
- CSIT test environment is now versioned, with ver. 1 associated
with CSIT rls1908 git branch as of 2019-08-21, and ver. 2
associated with CSIT rls2001 and master git branches as of
2020-03-27.
- To identify performance changes due to VPP code changes from
v20.01.0 to v20.05.0, both have been tested in CSIT environment
ver. 2 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`.
#. 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.
- **General Code Housekeeping**: Ongoing RF keywords optimizations,
removal of redundant RF keywords and aligning of suite/test
setup/teardowns.
#. PRESENTATION AND ANALYTICS LAYER
- **Graphs layout improvements**: Improved performance graphs layout
for better readibility and maintenance: test grouping, axis
labels, descriptions, other informative decoration.

Known Issues

List of known issues in |csit-release| for VPP performance tests:
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| # | JiraID | Issue Description |
+====+=========================================+===========================================================================================================+
| 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>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 3 | `CSIT-1498 | Memif tests are sporadically failing on initialization of memif connection. |
| | <https://jira.fd.io/browse/CSIT-1498>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 4 | `VPP-1677 | 9000B ip4 nat44: VPP crash + coredump. |
| | <https://jira.fd.io/browse/VPP-1677>`_ | VPP crashes very often in case that NAT44 is configured and it has to process IP4 jumbo frames (9000B). |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 5 | `CSIT-1591 | 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-1499>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
| +-----------------------------------------+ |
| | `VPP-1763 | |
| | <https://jira.fd.io/browse/VPP-1763>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 6 | `VPP-1675 | IPv4 IPSEC 9000B packet tests are failing as no packet is forwarded. |
| | <https://jira.fd.io/browse/VPP-1675>`_ | Reason: chained buffers are not supported. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 7 | `CSIT-1593 | IPv4 AVF 9000B packet tests are failing on 3n-skx while passing on 2n-skx. |
| | <https://jira.fd.io/browse/CSIT-1593>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 8 | `CSIT-1675 | Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds behaviour and performance became inconsistent following |
| | <https://jira.fd.io/browse/CSIT-1675>`_ | the upgrade to the latest Ubuntu 18.04 LTS kernel version (4.15.0-72-generic) and associated microcode |
| | | packages (skx ucode 0x2000064, clx ucode 0x500002c). VPP as well as DPDK L3fwd tests are affected. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 9 | `CSIT-1679 | All 2n-clx VPP ip4 tests with xxv710 and avf driver are failing. |
| | <https://jira.fd.io/browse/CSIT-1679>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 10 | `CSIT-1680 | Some 2n-clx cx556a rdma tests are failing. |
| | <https://jira.fd.io/browse/CSIT-1680>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 11 | `CSIT-1699 | Root Cause Analysis for CSIT-2001. Investigate high stdev of tests with VPP inside VM. |
| | <https://jira.fd.io/browse/CSIT-1699>`_ | |
| +-----------------------------------------+ |
| | `CSIT-1704 | |
| | <https://jira.fd.io/browse/CSIT-1704>`_ | |

| 12 | `CSIT-1699 | Root Cause Analysis for CSIT-2001. Identify cause of dot1q-l2xcbase progression. |
| | <https://jira.fd.io/browse/CSIT-1699>`_ | |
