Subject: [PATCH] Add module "90nvdimm" for NVDIMM support
|
|
|
|
Detection of persistent memory devices works mostly out of the box
|
|
already. Only the "provider" modules for ndbus devices, which are responsible
|
|
to extract information of available NVDIMM devices and their configuration
|
|
from system firmware, are only indirectly linked into the module stack.
|
|
Examples for such modules are nfit.ko, nd_e820.ko, and virtio-pmem.ko.
|
|
|
|
Add a module that resolves these dependencies.
