Challenges of providing Remote DMA access to Persistent Memory - Matthew Wilcox, Intel

Persistent Memory poses some new challenges to the Linux kernel. One of the trickiest problems is simultaneously supporting direct access to persistent memory and Remote DMA access. The DAX infrastructure provides direct access to persistent memory by removing the page cache, but the page cache provides an important layer of indirection between the filesystem storage and the memory used to cache that file.

This talk will present three different solutions to the problem and contrast their effects on filesystems, the VM, the VFS and RDMA device drivers.
