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

Claim 0:
1. An information handling system, comprising:
a processor; and
a compute express link (CXL) device coupled to the processor by a peripheral component interconnect-express (PCIe)/CXL link;
wherein the processor is configured to initiate a link training on the PCIe/CXL link, to determine that the PCIe/CXL link failed to train to a CXL link signaling rate, to train 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, to operate the CXL device as a PCIe device only in response to training the PCIe/CXL link as a PCIe link, and to report that the CXL device failed to initialize as a CXL device in response to operating the CXL device as the PCIe device.
