CXL-DISABLE-BUS(1)                cxl Manual                CXL-DISABLE-BUS(1)

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.
