cxl-disable-memdev1
Deactivate / hot-remove a given cxl memdev
Usage
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.
-b, --bus=
Restrict the operation to the specified bus.
-
-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. Going down this path does not offline active memory if they are currently online. User is recommended to offline and disable the appropriate regions before disabling the memdevs.
-
-v -
Turn on verbose debug messages in the library (if libcxl was built with logging and debug enabled).
