cxl-read-labels1
Read out the label area on a cxl memdev
Usage
cxl read-labels
<mem0>
[<mem1>..<memN>]
[<options>]
Overview
The region label area is a small persistent partition of capacity available on some CXL memory devices. The label area is used to and configure or determine the set of memory devices participating in different interleave sets. This command dumps the raw binary data in a memdev’s label area to stdout or a file. In the multi-memdev case the data is concatenated.
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.
-s, --size=
Limit the operation to the given number of bytes. A size of 0 indicates to operate over the entire label capacity.
-O, --offset=
Begin the operation at the given offset into the label area.
-
-v -
Turn on verbose debug messages in the library (if libcxl was built with logging and debug enabled).
-b, --bus=
Restrict the operation to the specified bus.
