individually for each 4 KB page, stored in a translation table in local memory of Type 2 devices. Unlike other CPU-to-CPU memory coherency protocols, this arrangement only requires the host CPU memory controller to implement the cache agent; such asymmetric approach reduces implementation complexity and reduces latency.
582:
CXL 3.0 allows multiple Type 1 and Type 2 devices per each CXL root port; it also adds multi-level switching, helping implement device fabrics with non-tree topologies like mesh, ring, or spline/leaf. Each node can be a host or a device of any type. Type 3 devices can implement Global Fabric

On August 2, 2022, the CXL Specification 3.0 was released, based on PCIe 6.0 physical interface and PAM-4 coding with double the bandwidth; new features include fabrics capabilities with multi-level switching and multiple device types per port, and enhanced coherency with peer-to-peer DMA and memory
578:
CXL 3.0 replaced bias modes with enhanced coherency semantics, allowing Type 2 and Type 3 devices to back invalidate the data in the host cache when the device has made a change to the local memory. Enhanced coherency also helps implement peer-to-peer transfers within a virtual hierarchy of devices
511:
CXL.cache and CXL.mem protocols operate with a common link/transaction layer, which is separate from the CXL.io protocol link and transaction layer. These protocols/layers are multiplexed together by an
Arbitration and Multiplexing (ARB/MUX) block before being transported over standard PCIe 5.0 PHY

Consortiums announced plans to implement interoperability between the two technologies, with initial results presented in
January 2021. On November 10, 2021, Gen-Z specifications and assets were transferred to CXL, to focus on developing a single industry standard. At the time of this announcement,

announced a 128 GB DDR5 based memory expansion module that allows for terabyte level memory expansion along with high performance for use in data centres and potentially next generation PCs. An updated 512 GB version based on a proprietary memory controller was released on May 10, 2022.
570:
Type 2 devices implement two memory coherence modes, managed by device driver. In device bias mode, device directly accesses local memory, and no caching is performed by the CPU; in host bias mode, the host CPU's cache controller handles all access to device memory. Coherence mode can be set

On
November 10, 2020, the CXL Specification 2.0 was released. The new version adds support for CXL switching, to allow connecting multiple CXL 1.x and 2.0 devices to a CXL 2.0 host processor, and/or pooling each device to multiple host processors, in
