CXL tutorials & labs.

The most complete CXL curriculum on the internet — starting from the memory-wall and accelerator-explosion context (CPU-centric limits, data-movement costs, PCIe ceiling) before touching any CXL protocol layer, then through the CXL stack, PCIe foundation, the three CXL protocols (.io / .cache / .mem), the three device types (1 / 2 / 3), memory expansion, memory pooling, coherency fundamentals and CXL coherency flows, fabric architecture and switches, memory devices, performance, security, the CXL 2.0 / 3.0 capability deltas, AI and data-centre case studies, RTL design, verification, debugging, real-industry case studies (AI clusters, memory-expansion cards, hyperscale pools), and the chiplet / composable-infrastructure future.
