Subject: [PATCH v2 0/2] NVDIMM memory error notification support
Date: Thu, 8 Jun 2017 12:36:56 -0600 [thread overview]
Message-ID: <20170608183658.24731-1-toshi.kani@hpe.com> (raw)
ACPI 6.2 defines a new ACPI notification value to NVDIMM Root Device.
This allows BIOS to inform the OS that new uncorrectable memory error
is detected during run-time.
This patch-set adds support of this notification, which starts ARS and
updates badblocks information to prevent the OS from consuming the new
error.
v2:
- Set flags Bit[1] for Start ARS. (Dan Williams)
