		hisi_raid - HUAWEI SCSI RAID Controller driver
		==============================================

		This file describes the hisi_raid SCSI driver for HUAWEI
		RAID controllers. The hisi_raid driver is the first
		generation RAID driver.

		For hisi_raid controller support, enable the hisi_raid driver
		when configuring the kernel.

		hisi_raid specific entries in /sys
		=================================

		hisi_raid host attributes
		------------------------
		- /sys/class/scsi_host/host*/csts_pp
		- /sys/class/scsi_host/host*/csts_shst
		- /sys/class/scsi_host/host*/csts_cfs
		- /sys/class/scsi_host/host*/csts_rdy
		- /sys/class/scsi_host/host*/fw_version

		The host csts_pp attribute is a read only attribute. This attribute
		indicates whether the controller is processing commands. If this attribute
		is set to ‘1’, then the controller is processing commands normally. If
		this attribute is cleared to ‘0’, then the controller has temporarily stopped
		processing commands in order to handle an event (e.g., firmware activation).

		The host csts_shst attribute is a read only attribute. This attribute
		indicates status of shutdown processing.The shutdown status values are defined
		as:
		====== ==============================
		Value Definition
		====== ==============================
		00b Normal operation
		01b Shutdown processing occurring
		10b Shutdown processing complete
		11b Reserved
		====== ==============================
		The host csts_cfs attribute is a read only attribute. This attribute is set to
		’1’ when a fatal controller error occurred that could not be communicated in the
		appropriate Completion Queue. This bit is cleared to ‘0’ when a fatal controller
		error has not occurred.

		The host csts_rdy attribute is a read only attribute. This attribute is set to
		‘1’ when the controller is ready to process submission queue entries.

		The fw_version attribute is read-only and will return the driver version and the
		controller firmware version.

		hisi_raid scsi device attributes
		------------------------------
		- /sys/class/scsi_device/X\:X\:X\:X/device/raid_level
		- /sys/class/scsi_device/X\:X\:X\:X/device/raid_state
		- /sys/class/scsi_device/X\:X\:X\:X/device/raid_resync

		The device raid_level attribute is a read only attribute. This attribute indicates
		RAID level of scsi device(will dispaly "NA" if scsi device is not virtual disk type).

		The device raid_state attribute is read-only and indicates RAID status of scsi
		device(will dispaly "NA" if scsi device is not virtual disk type).

		The device raid_resync attribute is read-only and indicates RAID rebuild processing
		of scsi device(will dispaly "NA" if scsi device is not virtual disk type).
