Abstract
A CXL memory subsystem unavailability recovery system includes a computing device having a CXL device, CXL memory subsystems, a non-volatile memory system, and a CXL memory subsystem unavailability recovery subsystem. The CXL memory subsystem unavailability recovery subsystem configures the first CXL device to use a first CXL memory subsystem, and copies data stored in the first CXL memory subsystem by the first CXL device to the non-volatile memory system to generate back-up data. During runtime operations for the computing device, the CXL memory subsystem unavailability recovery system determines the first CXL memory subsystem is unavailable, copies the back-up data from the non-volatile memory system to a second CXL memory subsystem, and configures the first CXL device to use the second CXL memory subsystem and stop using the first CXL memory subsystem without requiring initialization of the computing device subsequent to the determination that the first CXL memory subsystem was unavailable.
