NAME

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

SYNOPSIS

       cxl enable-port <port0> [<port1>..<portN>] [<options>]

       A port 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

       -e, --endpoint
           Toggle from treating the port arguments as Switch Port identifiers to Endpoint Port identifiers.

       -m, --enable-memdevs
           Try to enable descendant memdevs after enabling the port. Recall that a memdev is only enabled after
           all CXL ports in its device topology ancestry are enabled.

       --debug
           Turn on additional debug messages including library debug.
