12 A generic DIMM device object, named /dev/nmemX, is registered for each
13 memory device indicated in the ACPI NFIT table, or other platform
14 NVDIMM resource discovery mechanism. The LIBNVDIMM core provides a
15 built-in driver for these DIMM devices. The driver is responsible for
16 determining if the DIMM implements a namespace label area, and
17 initializing the kernel’s in-memory copy of that label data.
18
19 The kernel performs runtime modifications of that data when namespace
20 provisioning actions are taken, and actively blocks userspace from
21 initiating label data changes while the DIMM is active in any region.
22 Disabling a DIMM, after all the regions it is a member of have been
23 disabled, allows userspace to manually update the label data to be
24 consumed when the DIMM is next enabled.

30 A 'nmemX' device name, or a dimm id number. The keyword 'all' can
31 be specified to carry out the operation on every dimm in the system,
32 optionally filtered by bus id (see --bus= option).
33
34 -b, --bus=
35 Enforce that the operation only be carried on devices that are
36 attached to the given bus. Where bus can be a provider name or a
37 bus id number.
