Meetings are public, and DPDK community memb= ers are welcome to attend. NOTE: Next meeting will be on Wednesday 2023-03-09 @3pm UTC, and will be ch= aired by Jerin. 1) Agenda topic: Atomic operations abstraction solution - General consensus is to add support for MSVC in DPDK - Currently, DPDK is limited to static linking. Adding support for MSVC wil= l allow for dynamic linking among other advantages. - Porting the use of atomics intrinsics is 70% of the effort required for a= dding support for MSVC. - Dropping support for Redhat 7, GCC version 4.8.5 in 23.11 release - Thomas had discussions with few people from Redhat and dropping support = in 23.11 is acceptable. - Kevin/Maxime - EOL for Centos 7 is July 11 2024 - Sounds like a good tim= e to drop support in 23.11. Kevin to check internally at Redhat. - MSVC supports stdatomics (atomic APIs from stdatomic.h) - This is the way forward chosen for supporting C11 atomic APIs. Shim that= provides abstract APIs is not required. - Adding support for MSVC in DPDK - Thomas asked for a write up on current status of support for MSVC and a = plan to get the support added to DPDK - Tyler will provide this to a point where the support is on par with clan= g and gcc. This should be updated in dpdk.org. - Changes required to support MSVC can be merged after 23.03 release. - Patches for supporting C11 atomic APIs will be merged after 23.07 releas= e. The patches can be submitted earlier to the mailing list to get them rev= iewed and tested. 2) Agenda topic: Deprecating rte_atomics_* and rte_smp_* APIs - Most of the code in DPDK uses the compiler built-ins now. - rte_ring library still uses the rte_atomics_* and rte_smp_* APIs. Arm has= encountered few performance issues which need to be understood. 3) Agenda topic: MAC address set API behavior - The definition of the current API is not clear - The priority is address this for 23.03 is reduced as 23.03 RC1 is complet= ed - Changing the behavior of the existing APIs is a challenge - One option is= to introduce new APIs to manage the list of MAC addresses. - Need consistent behavior across the drivers - This needs further discussion with the rest of the community - Decision was taken to move the email conversation to dev mailing list 4) Agenda topic: Meeting invites on announce mailing list - Meeting notices do not need to go to announce mailing list. - Announce mailing list should be only for release announcements and events= such as DPDK summits. 5) Agenda topic: Process to admit new library - Please review the process for admitting the new library.
