The Linux Plumbers 2017 RDMA mini-conference track continues tradition established in 2016, where we discussed different range of topics, starting from kernel core (integration into netdev, new fabrics, …) through kernel ABI changes upto userspace libraries.

That mini-conference was extremely fruitful with a lot of code proposed and merged afterwards.

  • RDMA core (consolidated library) - gaps and how to unify UAPI header
  • Contiguous memory
  • Exposing device memory directly to application
  • Containers: GID isolations
  • Scope of RDMA subsystem (new fabrics)
  • RDMA as part of netdev stack
  • RDMAtool
  • RDMA userspace library
  • Kernel ABI
  • Documentation effort
  • Testing

Proposed Schedule (tentative)

  • Paravirtual RDMA device by Marcel and Yuval.
  • Device statistics information (counters) through RDMAtool by Dennis.
  • Connection information through RDMAtool by Leon.
  • kABI update by Matan.
  • Persistent RDMA device names by Leon
  • Backporting issues with multi-subsystem device (RDMA + netdev) by Don

Topics which is nice to discuss, but we need speakers/audience

  • Adding NUMA hints to *all* rdma resources.
  • SRQ sizing. No one knows what is a correct SRQ size.
  • Adaptive interrupt moderation.
  • Striding receive queue in core API
