Paper Title: Innovations in CXL: Novel Device Types, Capabilities, and Interconnects

Paper Abstract: This session introduces 3 new areas of the CXL 3.0 specification: CXL Multi-Headed Devices, a new device type that supports simultaneous connection to multiple hosts: An overview is provided of the architecture of such devices, their management, and example use cases. CXL Dynamic Capacity Device (DCD) capability, a new device capability to simplify migration of memory resources between hosts: An overview is provided of the different types of devices that may implement DCD, their management, example use cases, and how memory resources are presented. CXL Fabrics, a new multi-level switch architecture: CXL Fabrics are not restricted to tree-based topologies and can scale to 4,096 nodes, offering substantial scale and flexibility. The presentation will cover the transport level details, routing model, and management architecture.
