NVM Express Support for CXL

As CXL® becomes the memory interface protocol of choice, connecting CXL memory and NVMe® Subsystem Local Memory (SLM) becomes critical. SLM allows access to memory on an NVMe device with NVMe commands. This memory is then used for the Computational Programs Command set. To improve performance and to enable new paradigms of Computational Programs, it is beneficial for the SLM to be able to be accessed using CXL. TP4184 is being developed to allow the mapping of SLM to the Host Physical Memory Address space using Host-Managed Device Memory (HDM) addressing. In this presentation, Bill Martin (Samsung) and Jason Molgaard (Solidigm), will bring you up to speed on where this development effort is.
