Subject: [PATCH 0/3] acpi, nfit: Add dirty shutdown count to sysfs
Date: Wed, 26 Sep 2018 21:24:20 -0700	[thread overview]
Message-ID: <153802226065.833068.11943510429252969385.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)

The Intel NVDIMM command specification publishes a dirty-shutdown-count
in addition to the dirty-shutdown / flush-failed indication that comes
from the ACPI NFIT. This is expected to be a common property of NVDIMMs
and is a static hardware health detail to be cached / exported via
sysfs.

Add plumbing for retrieving this data at driver load time, publish the
count, and use the dynamically retrieved dirty-shutdown indicator to
augment the existing 'flush_failed' flag.
