What are the 3 CXL protocols?
- CXL.io is used for initialization, link-up, device discovery and enumeration, and register access. It provides a non-coherent load/store interface for I/O devices similar to PCIe® 5.0.
- CXL.cache defines interactions between a Host and Device, which allows CXL devices to cache host memory with low latency.
- CXL.mem provides a Host processor with direct access to Device-attached memory using load/store commands.
