-CSIT Release Notes\r
-==================\r
-\r
-Changes in CSIT |release|\r
--------------------------\r
-\r
-#. **Added VPP performance tests**\r
-\r
- - **MRR tests** : New MRR tests measure the packet forwarding rate\r
- under the maximum load offered by traffic generator over a set\r
- trial duration, regardless of packet loss. Maximum load for\r
- specified Ethernet frame size is set to the bi-directional link\r
- rate. MRR tests are used for continuous performance trending and\r
- for comparison between releases.\r
-\r
- - **SRv6** : Initial SRv6 (Segment Routing IPv6) tests verifying\r
- performance of IPv6 and SRH (Segment Routing Header)\r
- encapsulation, decapsulation, lookups and rewrites based on\r
- configured End and End.DX6 SRv6 egress functions.\r
-\r
-#. **Presentation and Analytics Layer (PAL)**\r
-\r
- - Added continuous performance measuring, trending and anomaly\r
- detection. Includes new PAL code and Jenkins jobs for Performance\r
- Trending (PT) and Performance Analysis (PA) producing performance\r
- trending dashboard and trendline graphs with summary and drill-\r
- down views across all specified tests that can be reviewed and\r
- inspected regularly by FD.io developers and users community.\r
-\r
-#. **Test Framework Optimizations**\r
-\r
- - **Performance tests efficiency** : Qemu build/install\r
- optimizations, warmup phase handling, vpp restart handling.\r
- Resulted in improved stability and reduced total execution time by\r
- 30% for single pkt size e.g. 64B/78B.\r
-\r
- - **General code housekeeping** : ongoing RF keywords\r
- optimizations, removal of redundant RF keywords.\r
-\r
-Performance Changes\r
--------------------\r
-\r
-Relative performance changes in measured packet throughput in CSIT\r
-|release| are calculated against the results from CSIT |release-1|\r
-report. Listed mean and standard deviation values are computed based on\r
-a series of the same tests executed against respective VPP releases to\r
-verify test results repeatibility, with percentage change calculated for\r
-mean values. Note that the standard deviation is quite high for a small\r
-number of packet throughput tests, what indicates poor test results\r
-repeatability and makes the relative change of mean throughput value not\r
-fully representative for these tests. The root causes behind poor\r
-results repeatibility vary between the test cases.\r
-\r

+Release Notes
+=============
+
+Changes in |csit-release|
+-------------------------
+
+#. VPP PERFORMANCE TESTS
+
+ - CSIT test environment is versioned, see
+ :ref:`test_environment_versioning`.
+
+ - 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. 4 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 improvements**: Added possibility to use Gbps on Y-axis in
+ Packet Throughput and Speedup Multi-Core graphs, added unidirectional
+ mode to the Latency graphs.

++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| # | 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 | `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). |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 4 | `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. |

+| 5 | `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. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 6 | `CSIT-1593 | IPv4 AVF 9000B packet tests are failing on 3n-skx while passing on 2n-skx. |
