Plumbing Challenges in Dynamic Capacity Device - Linux Plumbers Conference

Explore the latest developments and challenges in implementing CXL 3.0 Dynamic Capacity Device (DCD) in this Linux Plumbers Conference talk. Delve into the current architecture and enhanced DCD flows, covering topics such as interleaving, partial extent usage, memory sharing, and handling asynchronous and forced memory release. Learn about the progress made since the previous year's session, including initial code reviews and community engagement in fabric management and DCD emulation. Engage in open discussions about potential improvements and foreseen challenges in the current architecture, as well as considerations for improved emulation and fabric manager flows. This talk is ideal for developers interested in CXL software, memory management, orchestrators, fabric managers, and those designing use cases for memory pooling.
