The board had a detailed discussion on ABI stability. No final decisions were made, and the topic will continue to be explored. Key discussion points included:
a) Proposal to extend the ABI compatibility window from 1 year to 2 years.
b) Evaluated the feasibility of making asymmetric crypto device functions non-inline.
c) Encouraged use of initialization functions for public structures, acknowledging that full coverage may not be achievable.
d) Concerns from consumers (e.g., OVS) regarding delays caused by ABI change restrictions; suggestion to consider multiple LTS streams as a potential solution.
e) Observed that product owners prefer LTS, regardless of ABI/API changes.
f) Suggested that ABI changes be limited to non-LTS versions.
g) Agreed to continue discussions at the upcoming U.S. Summit and via the DPDK mailing list on above suggestion.
h) Topic to remain on the agenda for the next Technical Board meeting.
