Meetings are public, and DPDK community members are welcome to attend. NOTE: Next meeting will be on Wednesday 2021-12-01 @3pm UTC, and will be chaired by Thomas. 1. Governing board ================== Jerin's slides for governing board were reviewed with no new feedback. 2. Review the default maximum number of cores ============================================= Continued discussion about the default number of cores from last meeting. The proposed patch only addressed AMD EPYC platform but the issue is more general since today's limit of 128 cores will be on many high end two socket x86 system. A suggestion is to increase this to default maximum 256 cores for all x86 platforms; to avoid any out of the box user experience issues. Users can remap lcores today from the command line to run with up to 128 cores used (out of a much larger set). But this requires users explicitly configuring the command line. Suggestion was made to have an new command line flag to automatically create the mapping; based on the lcore command line. Something like the following dpdk-XXX --cpu-offset 128 --lcores 0-2 would be same as: dpdk-XXX -lcores 0@128,1,@129,2@130 Olivier will investigate 3. Review of outdated examples. =============================== Discussion of future status of examples that are not being maintained: - ioat was removed in 21.11. - ntb should be moved to different directory to indicate that it is vendor specific. - vmdq examples might be candidate for deprecation. Bruce to check with Intel - performance-thread should be deprecated and removed. - flow filtering and flow classify examples overlap. 4. LTS release maintenance ========================== The current LTS release and maintenance schedule on web site needs update. The plan is for LTS releases to come immediately after the main DPDK release. Now that main DPDK releases are three times a year, the LTS release schedule needs to be updated as well. The other issues is extending the LTS releases to 3 years instead of just 2. General consensus was that this is good idea but will require additional resources from LTS maintainers and vendor validation teams. Will wait for confirmation before committing to longer cycle. For the 21.11 LTS, Kevin was approved by Techboard as LTS maintainer. 5. KNI deprecation ================== Deprecation was previously discussed by TB, discused in more detail. Ferruh proposed time line is: - 22.11 move to kmod repository KNI library and example won't be built by default - 23.11 final removal Approved, Ferruh to follow up with more patches.
