Meetings are public, and DPDK community members are welcome to attend. This meeting was special, in Dublin on September 11th before the summit. Agenda and minutes can be found at http://core.dpdk.org/techboard/minutes Next meeting will be on Wednesday 2023-Oct-18 @ 3pm UTC, and will be chaired by Thomas. Agenda Items ============ Bugzilla -------- Ajit has said he will continue maintaining Bugzilla. What additional maintenance is necessary? The bug backlog has grown and it is not being used as much as it could be. Would be good to have (automated?) status report to mailing list. Need to make sure that all bugs are assigned to correct owners. Techboard Minutes ----------------- Last entry on DPDK techboard minutes is from May 17. Need to fill in with later minutes. There will be gap in summer because a couple meetings did not have quorum. Power Management ---------------- There was a discussion of power management in DPDK. Thomas raised the issue that we don't describe power management in the web site and marketing which leads to assumptions that DPDK does not do any power management. Kevin said that recent OpenVswitch changes dramatically improved power consumption. He is writing a blog describing details. Many network equipment vendors use (or base their design) off of testpmd application which has no power management integration. There is a proposed patch which is not integrated to do some sleeps in testpmd. http://inbox.dpdk.org/dev/20230316151438.186241-2-aharivel@redhat.com/ https://patchwork.dpdk.org/project/dpdk/list/?series=27422&state=%2A&archive=both Still needs followup. Perhaps a more general and complete solution. Power management in VM's is even more difficult. Guest really does not have a good way to tell host desired power profile. Right now, the method is to use interrupts which has long latency. There has be some ongoing work on QEMU side: https://patchew.org/QEMU/20230616140830.316655-1-aharivel@redhat.com/ Power management also depends on work load and application. The high impact changes are in the application; and there is not a simple API for doing PM in application. There is a library for power management in DPDK but it is not complete enough. Upcoming Joint Meeting ---------------------- There is an upcoming joint meeting of Tech and Governing board on 17th Oct @ 10am EDT, 7am PDT, 1400 UTC.
