Subject: [PATCH 1/2] Add module "90nvdimm" for NVDIMM support
Date: Thu, 30 Jan 2020 16:18:20 +0100 [thread overview]
Message-ID: <20200130151821.24042-1-mwilck@suse.com> (raw)
From: Martin Wilck <mwilck-IBi9RG/b67k@public.gmane.org>
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.
