Minutes

=====================================================================
General Announcements
* There is a new member of the DTS slack, Zack Vonler, who is implementing
a new PMD and would like to use DTS to validate his new PMD is conforming
to DPDK

=====================================================================
CI Status

---------------------------------------------------------------------
AWS Lab
* None

---------------------------------------------------------------------
UNH-IOL Community Lab
* PW-CI: Working on standing up an instance of pw-ci, so we can start to
poll for some patches and better understand if this can be used in our lab
   * Adam and Patrick still need to stand up a working instance of the
current (bash) pw-ci
   * Aaron has noted that he wants to decouple the components used for
entering results into the DB and the component involved in sending reports
   * Aaron can help if we are stuck with the setup.
      * We can add some additional documentation based on this (if indeed
there is missing info)
* Windows server 2025:
   * We are moving over the 3 compiler toolchains and automated builds to
the new Windows server VM
* Missing stdin on some log files:
   * Addin stdin to log files where that is missing (i.e. make sure to
capture meson args used in setup)
* Mbuf_fast_free
   * Patrick needs to make sure we are able to add in the manual enable of
mbuf fast release when the default behavior (changing from default on to
default off) is modified in dpdk main

---------------------------------------------------------------------
Intel Lab
* Sadashiva Rao is a new contact that we should CC on discussions relating
to the Intel lab.
Github Actions Robot
* Coderabbit feedback:
   * It is a mixed bag. Sometimes it can catch real issues, and other times
it makes suggestions that are just nitpicking, and other times the feedback
is just “nonsense.” There is some discussion about moving to a different
tool
   * David submitted a patch in an attempt to tailor it further
      * It is tailored through an entry YAML
      * If the project is moving away from coderabbit anyways, it’s unclear
whether it makes sense to add a coderabbit artifact to the tree.
   * Sourcery was not very useful
* Cirrus CI:
   * On David’s fork, he used it for freebsd build testing
* Aaron is working on porting the pw-ci project from bash scripts to Python

---------------------------------------------------------------------
Loongson Lab
* None

=====================================================================
DTS Improvements & Test Development
* Tx offloads
   * Is reviewed by Luca
   * V6 is out
   * Patrick and Andrew to look at this together.
* Single core forwarding test
   * V4 is sent out
   * There is a blocker for enabling mbuf_fast_free here, due to a
dependency on the tx_offloads series.
      * When that series is merged, I will rebase, send a v5 with
mbuf_fast_free enabled
   * Most of Luca’s comments from the V3 should be resolved.
   * Default params: I think that we should encourage testsuite writers to
always include defaults for the testsuite specific params, and allow users
to override those values from tests_config.yaml as needed.
   * Right now, after running all packet combinations, we print a big table
at the end in the console. But, we are not writing this to a file in
/output/single_core_forwarding. Patrick to add some structured file here to
store the latest MPPS results.
* RSS
   * For debugging, Dean is printing the predicted table, the RETA table
returned by testpmd, and all the packet/queue combos to understand whether
the testsuite is failing due to the mellanox PMD/device or because of our
python code
* Virtio/Vhost
   * Dean is writing a v2 based on Luca’s comments
   * Patrick needs to do a review
* QinQ:
   * We still need to collect the Broadcom results
   * Should be able to merge soon after sharing those out

=====================================================================
Any other business
   * Next Meeting is Oct 16, 2025
   * DPDK RC1 is out next week, so let’s keep it up on reviews :)
