We are pleased to announce that the RDMA Microconference has been accepted into the 2019 Linux Plumbers Conference! RDMA has been a microconference at Plumbers for the last three years and will be continuing its productive work for a fourth year. The RDMA meetings at the previous Plumbers have been critical in getting improvements to the RDMA subsystem merged into mainline. These include a new user API, container support, testability/syzkaller, system bootup, Soft iWarp, and more. There are still difficult open issues that need to be resolved, and this year’s Plumbers RDMA Microconfernence is sure to come up with answers to these tough problems.

Topics for this year include:

• RDMA and PCI peer to peer for GPU and NVMe applications, including HMM and DMABUF topics
• RDMA and DAX (carry over from LSF/MM)
• Final pieces to complete the container work
• Contiguous system memory allocations for userspace (unresolved from 2017)
• Shared protection domains and memory registrations
• NVMe offload
• Integration of HMM and ODP

And new developing areas of interest:

• Multi-vendor virtualized ‘virtio’ RDMA
• Non-standard driver features and their impact on the design of the subsystem
• Encrypted RDMA traffic
• Rework and simplification of the driver API

Come and join us in the discussion of improving Linux’s ability to access direct memory across high-speed networks.

We hope to see you there!
