Subject: [PATCH 0/2] Notify NVME HW when system reset happens
Date: Mon, 7 Aug 2017 11:31:40 +0800 [thread overview]
Message-ID: <20170807033142.177248-1-ruiyu.ni@intel.com> (raw)
Per NVM Express Spec, software should notify NVME HW when shutdown
occurs.
The host should set the Shutdown Notification (CC.SHN) field to 01b
to indicate a normal shutdown operation. The controller indicates
when shutdown processing is completed by updating the Shutdown Status
(CSTS.SHST) field to 10b.
