NAME

       cxl-disable-bus - Shutdown an entire tree of CXL devices

SYNOPSIS

       cxl disable-bus <root0> [<root1>..<rootN>] [<options>]

       For test and debug scenarios, disable a CXL bus and any associated memory devices from CXL.mem
       operations.

OPTIONS

       -f, --force
           DANGEROUS: Override the safety measure that blocks attempts to disable a bus 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
           If the cxl tool was built with debug disabled, turn on debug messages.
