4 Changes in |csit-release|
5 -------------------------
7 #. VPP PERFORMANCE TESTS
9 - CSIT test environment is versioned, see
10 :ref:`test_environment_versioning`.
12 - **GENEVE tests**: Added VPP performance tests for GENEVE tunnels.
14 - See :ref:`geneve_methodology` for more details.
16 - **NAT44 tests**: Added new test type, pure throughput tests.
17 They are similar to PPS tests, but they employ ramp-up trials
18 to ensure all sessions are created (and not timing out)
19 for performance trials.
21 - **Jumbo for ipsec**: Test cases with 9000 byte frames are re-enabled
24 - **Randomized profiles**: Improved repeatability and cycle length.
25 For details, see :ref:`packet_flow_ordering`.
27 - **AMD 2n-tx2 testbed**: New physical testbed type installed in
28 FD.io CSIT, with VPP and DPDK performance data added to CSIT
29 trending and this report.
33 - **TRex ASTF**: Improved capability to run TRex in advanced stateful mode.
35 - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
36 still used in CSIT for all VPP scale tests. See known issues below.
38 - **General Code Housekeeping**: Ongoing code optimizations,
39 speed ups and bug fixes.
41 #. PRESENTATION AND ANALYTICS LAYER
43 - **Graphs improvements**: Updated Packet Latency graphs,
44 see :ref:`latency_methodology`.
55 List of known issues in |csit-release| for VPP performance tests:
57 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
58 | # | JiraID | Issue Description |
59 +====+=========================================+===========================================================================================================+
60 | 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520. DPDK reporting rx-errors, indicating L1 issue. |
61 | | <https://jira.fd.io/browse/CSIT-570>`_ | Suspected issue with HW combination of X710-X520 in LF testbeds. Not observed outside of LF testbeds. |
62 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
63 | 2 | `VPP-662 | 9000B packets not supported by NICs VIC1227 and VIC1387. |
64 | | <https://jira.fd.io/browse/VPP-662>`_ | |
65 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
66 | 3 | `CSIT-1763 | Adapt ramp-up phase of nat44 tests for different frame sizes. |
67 | | <https://jira.fd.io/browse/CSIT-1763>`_ | Currently ramp-up phase rate and duration values are correctly set for tests with 64B frame size. |
68 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
69 | 4 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
70 | | <https://jira.fd.io/browse/CSIT-1671>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
71 | +-----------------------------------------+ The usual PAPI library spends too much time parsing arguments, so even with async processing (hundreds of |
72 | | `VPP-1763 | commands in flight over socket), the VPP configuration for large scale tests (millions of messages) takes |
73 | | <https://jira.fd.io/browse/VPP-1763>`_ | too long. |
74 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
75 | 5 | `VPP-1934 | [i40e] Interfaces are not brought up from carrier-down. |
76 | | <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 |
77 | | | state "no-carrier" (<NO-CARRIER,BROADCAST,MULTICAST,UP>) because previously it was disabled via |
78 | | | "I40E_AQ_PHY_LINK_ENABLED" call, then VPP during initialization of AVF interface is not re-enabling |
79 | | | interface link via i40e driver to up. |
80 | | | CSIT implemented `workaround for AVF interface <https://gerrit.fd.io/r/c/csit/+/29086>`_ until fixed. |
