Patent ID: 11953974
Assignee: DELL PRODUCTS L.P.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 9:
10. A method, comprising:
coupling a processor to a compute express link (CXL) device by a peripheral component interconnect-express (PCIe)/CXL link;
initiating, by the processor, a link training on the PCIe/CXL link;
determining that the PCIe/CXL link failed to train to a CXL link signaling rate;
training the PCIe/CXL link as a PCIe link in response to determining that the PCIe/CXL link failed to train to the CXL link signaling rate;
operating the CXL device as a PCIe device only in response to training the PCIe/CXL link as a PCIe link; and
in operating the CXL device as the PCIe device, repurposing a CXL queue associated with the CXL device to the PCIe device.
