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.
25
27 <dimm>
28 A nmemX device name, or a dimm id number. Restrict the operation to
29 the specified dimm(s). The keyword all can be specified to indicate
30 the lack of any restriction, however this is the same as not
31 supplying a --dimm option at all.
32
33 -b, --bus=
34 A bus id number, or a provider string (e.g. "ACPI.NFIT"). Restrict
35 the operation to the specified bus(es). The keyword all can be
36 specified to indicate the lack of any restriction, however this is
37 the same as not supplying a --bus option at all.
