Meetings are public, and DPDK community members are welcome to attend. Agenda and minutes can be found at http://core.dpdk.org/techboard/minutes NOTE: Next meeting will be on Wednesday 2022-03-23 @3pm UTC, and will be ch= aired by Aaron. 1) Index based mempool lcore cache a) Limitations - Supports 4GB of contiguous memory for buffers b) 4GB of buffer space is enough in some use cases such as smart NICs and e= mbedded appliances c) L3fwd application does not show performance improvements. Another way to= view this is, same throughput can be achieved with less amount of resource= s d) Mempool performance unit test shows an improvement of ~13% for bulk size= of 32 on Arm platforms. On x86 there is a performance degradation, probabl= y due to the patch not being optimized for x86 e) Suggestion is to show performance improvement possibly with other apps s= uch as IPSec gateway which would place more pressure on cache. 2) GB meeting updates a) The outstanding security issues presented to GB are not critical. Plan t= o address 2 CVEs in the coming release. b) Jerin (or whoever is the TB rep) will sync up with the community on outs= tanding CVEs before the next GB meeting c) DTS GPL license files - look for re-writing the files, files with altern= ative license, keeping the files outside of the repo (use wget) d) GB needs more input from TB on ecosystem health 3) Python bindings a) Link to the presentation: https://docs.google.com/presentation/d/1PgOFo4= SqjWehH_YvVkGwij1XdPGIMxEPDINUI772Yb8/edit#slide=3Did.p b) Owen to create a small RFC to provide a feel for changes required c) One of the concerns is the maintenance overhead these bindings will intr= oduce Thanks, Honnappa
