Abstract
Embodiments for communicating between first and second hosts according to CXL.mem and CXL.cache protocols. A computer translates a CXL.mem M2S RwD with a Tag, received by a CXL Type 2 or Type 3 device (EP1) from the first host, to a CXL.cache D2H Req with a CQID. A CXL Type 1 or Type 2 device (EP2) sends the D2H Req to the second host, and receives a CXL.cache H2D Rsp with the CQID and a UQID. EP1 sends a CXL.mem S2M NDR with the Tag to the first host, and EP2 sends a CXL.cache D2H Data message with the UQID to the second host. Optionally, EP1 receives and terminates CXL.io/PCIe Configuration Request TLPs from the first host, the M2S RwD further includes a first physical address and Data, and the D2H Req further includes a second physical address.
