Hi All, This meeting is a follow up to the call earlier this week.
This week Sunil presented 3 different approaches to integrating DMA-Dev with OVS along with the performance impacts. https://github.com/Sunil-Pai-G/OVS-DPDK-presentation-share/blob/main/OVS%20vhost%20async%20datapath%20design%202022.pdf The approaches were as follows: * Defer work. * Tx completions from Rx context. * Tx completions from Rx context + lockless ring. The pros and cons of each approach were discussed but there was no clear solution reached. As such a follow up call was suggested to continue discussion and to reach a clear decision on the approach to take. Please see agenda as it stands below: Agenda * Opens * Continue discussion of 3x approaches from last week (Defer work, "V3", V4, links to patches in Sunil's slides above) * Design Feedback (please review solutions of above & slide-deck from last week before call to be informed) * Dynamic Allocation of DMA engine per queue * Code Availability (DPDK GitHub, OVS GitHub branches) Please feel free to respond with any other items to be added to the agenda.
