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 an a memdev id number, interpret the
<memdev> 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).
