DASH Workgroup Meeting Minutes 9/13/2023

[Kristina Moore]

Hello DASH Community –thank you for your time last Wednesday.

In summary, we were able to close out 3 Issues this week, .  In addition, Intel contributed a fix to the P4 DPDK which was merged into the P4C main branch, which we hope to leverage for future testing purposes – thank you @Fingerhut, John Andy and Intel!

Just a note that I will be at a conference next week – if anyone would like to co-lead the call with @Yusef Skinner, please ‘r’ to let me know.

As always, with respect to any of our DASH meetings High Availability (Tuesdays), Community (Wednesdays), or Behavioral Model (Thursdays) – please let me know if there are PRs, Q&A, or items you would like to discuss or present.

Other Notes:

 

PR415: [SAI] wrong code generated in libsai

-Kamil and Chris discussed the issue of the Sai metadata object code being compiled into the libsai library, which is unnecessary for abandoned distros.

Kamil proposed a solution of having a separate library for the Sai metadata object code, which Chris agreed to look into. Implications of removing SAI Meta;

Chris explained that the PTF test cases should still work, as the libsai meta will be separated and linked into the final output.

Chris clarified that the PTF test cases will still work, as the libsai meta will be separated and linked into the final output.
