cxl-disable-memdev(1)
NAME
cxl-disable-memdev - deactivate / hot-remove a given CXL memdev
SYNOPSIS
cxl disable-memdev <mem0> [<mem1>..<memN>] [<options>]
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 than a memdev id number, interpret the argument(s) as a list of serial numbers.
-f, --force
DANGEROUS: Override the safety measure that blocks attempts to disable a device if the tool determines the 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.
-v
Turn on verbose debug messages in the library (if libcxl was built with logging and debug enabled).
