NAME

       cxl-disable-port - disable / hot-remove a given CXL port and descendants

SYNOPSIS

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

       For test and debug scenarios, disable a CXL port and any memory devices dependent on this port being
       active for CXL.mem operation.

OPTIONS

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

       -f, --force
           DANGEROUS: Override the safety measure that blocks attempts to disable a port if the tool determines
           a descendent memdev is in active usage. Recall that CXL memory ranges might have been established by
           platform firmware and disabling an active device is akin to force removing memory from a running
           system.

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