#. 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.
-
- - **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.
-
- - **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.
-
- - **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).
+ - CSIT test environment is versioned, see
+ :ref:`test_environment_versioning`.
+
+ - **GENEVE tests**: Added VPP performance tests for GENEVE tunnels.
+ See :ref:`geneve_methodology` for more details.
+
+
+ - **GSO tests**: Added VPP performance tests for GSOtap and GSOvirtio.
+ All tested topologies are compared with GSO enabled and disabled.
+ In |csit-release| there is only 1t1c tests running.
+ See :ref:`gso_methodology` for more details.
+
+
+ - **NAT44 tests**: Added new test type, pure throughput tests.
+ They are similar to PPS tests, but they employ ramp-up trials
+ to ensure all sessions are created (and not timing out)
+ for performance trials.
+
+ - **Jumbo for ipsec**: Test cases with 9000 byte frames are re-enabled
+ in ipsec suites.
+
+ - **Randomized profiles**: Improved repeatability and cycle length.
+ For details, see :ref:`packet_flow_ordering`.
+
+ - **Arm 2n-tx2 testbed**: New physical testbed type installed in
+ FD.io CSIT, with VPP and DPDK performance data added to CSIT
+ trending and this report.
+
+ - **Framework speedup**: Shortened overall test job duration
+ by using a different test selection mechanism (using --test
+ instead of --include) and by avoiding unnecessary PAPI reconnects.
#. 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.
+ - **TRex ASTF**: Improved capability to run TRex in advanced stateful mode.
- - **General Code Housekeeping**: Ongoing RF keywords optimizations,
- removal of redundant RF keywords and aligning of suite/test
- setup/teardowns.
+ - **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 code optimizations,
+ speed ups 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.
+ - **Graphs improvements**: Updated Packet Latency graphs,
+ see :ref:`latency_methodology`.

-+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
-| 4 | `CSIT-1498 | Memif tests are sporadically failing on initialization of memif connection. |
-| | <https://jira.fd.io/browse/CSIT-1498>`_ | |
-+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
-| 5 | `CSIT-1499 | AVF tests are sporadically failing on initialization of AVF interface. |
-| | <https://jira.fd.io/browse/CSIT-1499>`_ | |
-+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
-| 6 | `VPP-1676 | 9000B ip4 memif errors - ip4-input: ip4 length > l2 length. |
-| | <https://jira.fd.io/browse/VPP-1676>`_ | IP4 jumbo frames (9000B) are dropped in case of tests with memif. |
-+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
-| 7 | `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). |
-+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
-| 8 | `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>`_ | |
-+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
-| 9 | `CSIT-1592 | VPP memif API does not enable memif zero-copy, resulting in different memif configuration vs. previously |
-| | <https://jira.fd.io/browse/CSIT-1592>`_ | tested VAT/CLI where memif zero-copy was enabled by default. Needs to be fixed in VPP. |
-| +-----------------------------------------+ |

-+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
-| 10 | `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. |

+| | <https://jira.fd.io/browse/CSIT-1763>`_ | Currently ramp-up phase rate and duration values are correctly set for tests with 64B frame size. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 4 | `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. |
+| +-----------------------------------------+ The usual PAPI library spends too much time parsing arguments, so even with async processing (hundreds of |
+| | `VPP-1763 | commands in flight over socket), the VPP configuration for large scale tests (millions of messages) takes |
+| | <https://jira.fd.io/browse/VPP-1763>`_ | too long. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 5 | `VPP-1934 | [i40e] Interfaces are not brought up from carrier-down. |
+| | <https://jira.fd.io/browse/VPP-1934>`_ | In case of i40e -based interface (e.g Intel x700 series NIC) is bound to kernel driver (i40e) and is in |
+| | | state "no-carrier" (<NO-CARRIER,BROADCAST,MULTICAST,UP>) because previously it was disabled via |
+| | | "I40E_AQ_PHY_LINK_ENABLED" call, then VPP during initialization of AVF interface is not re-enabling |
+| | | interface link via i40e driver to up. |
+| | | CSIT implemented `workaround for AVF interface <https://gerrit.fd.io/r/c/csit/+/29086>`_ until fixed. |
