NAME

       cxl-enable-memdev - activate / hot-add a given CXL memdev

SYNOPSIS

       cxl enable-memdev <mem0> [<mem1>..<memN>] [<options>]

       A memdev typically autoenables at initial device discovery. However, if it was manually
       disabled this command can trigger the kernel to activate it again. This involves detecting
       the state of the HDM (Host Managed Device Memory) Decoders and validating that CXL.mem is
       enabled for each port in the device’s hierarchy.

OPTIONS

       <memory device(s)>
           A memX device name, or a memdev id number. Restrict the operation to the specified
           memdev(s). The keyword all can be specified to indicate the lack of any restriction.

       -S, --serial
           Rather an a memdev id number, interpret the <memdev> argument(s) as a list of serial
           numbers.

       -v
           Turn on verbose debug messages in the library (if libcxl was built with logging and
           debug enabled).
