CI Status

---------------------------------------------------------------------
AWS Lab
* None
UNH-IOL Community Lab
* The Community Lab will have downtime for a few hours on Tuesday August
12, for system upgrades
* Pw-ci: Aaron visited the lab last week and was curious about whether the
Community Lab can leverage the pw-ci project, which handles patch polling,
patch apply, etc.
   * UNH guys to look at standing this up side by side with our existing
backend to evaluate its usefulness
   * https://github.com/ovsrobot/pw-ci
*  Had an infra failure on the ARM Grace server this week, and put in
reruns from August 4 - August 6 to correct this.
* Has been stable otherwise.

---------------------------------------------------------------------
Intel Lab
* There were some build failures from Intel CI from the docs build for DTS,
which should be fixed with this patch which removes autodoc_pydantic from
the build:
https://patchwork.dpdk.org/project/dpdk/patch/20250801114547.1128950-1-luca.vizzarro@arm.com/
* Nothing otherwise

---------------------------------------------------------------------
Github Actions Robot
* Started integration of pull request for Sourcery AI analysis.
   * This is inadvertently causing testing to run 2x because the extra PR
for Sourcery is being picked up by testing
   * Will have to decide which repo for the pull requests to live in, but
it can either be the DPDK repo or ovsrobot repo
   * Will publish the pull request link in the checkpatch email, so people
can click it and look at the AI bot’s comments
      * If the bot feedback/comments prove useful, then we can look at
setting up a system for sending the bot comments as mails on the mailing
list.

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