NAME

6       cxl-enable-memdev - activate / hot-add a given CXL memdev
7

SYNOPSIS

9       cxl enable-memdev <mem0> [<mem1>..<memN>] [<options>]
10
11       A memdev typically autoenables at initial device discovery. However, if
12       it was manually disabled this command can trigger the kernel to
13       activate it again. This involves detecting the state of the HDM (Host
14       Managed Device Memory) Decoders and validating that CXL.mem is enabled
15       for each port in the device’s hierarchy.
16

OPTIONS

18       <memory device(s)>
19           A memX device name, or a memdev id number. Restrict the operation
20           to the specified memdev(s). The keyword all can be specified to
21           indicate the lack of any restriction.
22
23       -S, --serial
24           Rather an a memdev id number, interpret the <memdev> argument(s) as
25           a list of serial numbers.
26
27       -b, --bus=
28           Restrict the operation to the specified bus.
29
30       -v
31           Turn on verbose debug messages in the library (if libcxl was built
32           with logging and debug enabled).
