User Space Storage Stack

Organizer: George Neville-Neil <gnn@freebsd.org> and Ilias Marinos

Abstract:

Inspired by netmap, a high­performance packet processing framework which directly maps the NIC buffer rings to userspace, we have implemented diskmapa conceptually similar system that enables userspace applications to directly map DMA memory used for transfering disk logical blocks. Although, a high­level view the two frameworks could demonstrate many similarities, there are important differences (stemming mostly from the fundamentally different DMA models and the nature of operations) that require a different approach.

Notes

Ilias describes diskmap to the group. A design discussion then follows in which the memory management is covered as that's an issue for any sort of "IO" map system.
