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.
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)

Ian
