+      <para>
+        Once upon a time, the Small Computer Systems Interface defined both
+        a parallel I/O bus and a data protocol to connect a wide variety of
+        peripherals (disk drives, tape drives, modems, printers, scanners,
+        optical drives, test equipment, and medical devices) to a host
+        computer.
+      </para>
+      <para>
+        Although the old parallel (fast/wide/ultra) SCSI bus has largely
+        fallen out of use, the SCSI command set is more widely used than ever
+        to communicate with devices over a number of different busses.
+      </para>
+      <para>
+        The <ulink url='http://www.t10.org/scsi-3.htm'>SCSI protocol</ulink>
+        is a big-endian peer-to-peer packet based protocol.  SCSI commands
+        are 6, 10, 12, or 16 bytes long, often followed by an associated data
+        payload.
+      </para>
+      <para>
+        SCSI commands can be transported over just about any kind of bus, and
+        are the default protocol for storage devices attached to USB, SATA,
+        SAS, Fibre Channel, FireWire, and ATAPI devices.  SCSI packets are
+        also commonly exchanged over Infiniband,
+        <ulink url='http://i2o.shadowconnect.com/faq.php'>I20</ulink>, TCP/IP
+        (<ulink url='http://en.wikipedia.org/wiki/ISCSI'>iSCSI</ulink>), even

+      <title>Design of the Linux SCSI subsystem</title>
+      <para>
+        The SCSI subsystem uses a three layer design, with upper, mid, and low
+        layers.  Every operation involving the SCSI subsystem (such as reading
+        a sector from a disk) uses one driver at each of the 3 levels: one
+        upper layer driver, one lower layer driver, and the SCSI midlayer.
+      </para>
+      <para>
+        The SCSI upper layer provides the interface between userspace and the
+        kernel, in the form of block and char device nodes for I/O and
+        ioctl().  The SCSI lower layer contains drivers for specific hardware
+        devices.
+      </para>
+      <para>
+        In between is the SCSI mid-layer, analogous to a network routing
+        layer such as the IPv4 stack.  The SCSI mid-layer routes a packet
+        based data protocol between the upper layer's /dev nodes and the
+        corresponding devices in the lower layer.  It manages command queues,
+        provides error handling and power management functions, and responds
+        to ioctl() requests.

+1. Added module parameter "poll_mode_io" to support for "polling"
+	(reduced interrupt operation).  In this mode, IO completion
+	interrupts are delayed. At the end of initiating IOs, the
+	driver schedules for cmd completion if there are pending cmds
+	to be completed.  A timer-based interrupt has also been added
+	to prevent IO completion processing from being delayed
+	indefinitely in the case that no new IOs are initiated.

+	with megaraid_sas.  Thanks to RB for providing the logs and

+i.	Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
+
+	Fix:	The driver is now throttling IO.
+	Checks added in megasas_queue_command to know if FW is able to
+	process commands within timeout period. If number of retries
+	is 2 or greater,the driver stops sending cmd to FW temporarily. IO is
+	resumed if pending cmd count reduces to 16 or 5 seconds has elapsed
+	from the time cmds were last sent to FW.
+
+ii.	FW enables WCE bit in Mode Sense cmd for drives that are configured
+	as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical
+	Disks are exposed with WCE=1. User is advised to enable Write Back
+	mode only when the controller has battery backup. At this time
+	Synhronize cache is not supported by the FW. Driver will short-cycle
+	the cmd and return sucess without sending down to FW.

-Use the following options to disable options in the SCSI driver.
-
-Using amiboot for example.....
-
-To disable Synchronous Negotiation....
-
-	amiboot -k kernel 53c7xx=nosync:0	
-
-To disable Disconnection....
-	
-	amiboot -k kernel 53c7xx=nodisconnect:0
-
-To disable certain SCSI devices...
-
-	amiboot -k kernel 53c7xx=validids:0x3F
-
-	this allows only device ID's 0,1,2,3,4 and 5 for linux to handle.
-	(this is a bitmasked field - i.e. each bit represents a SCSI ID)
-
-These commands work on a per controller basis and use the option 'next' to
-move to the next controller in the system.
-
-e.g.
-	amiboot -k kernel 53c7xx=nodisconnect:0,next,nosync:0
-
-	this uses No Disconnection on the first controller and Asynchronous
-	SCSI on the second controller.
-
-Known Issues:
-
-Two devices are known not to function with the default settings of using
-synchronous SCSI. These are the Archive Viper 150 Tape Drive and the 
-SyQuest SQ555 removeable hard drive. When using these devices on a controller
-use the 'nosync:0' option.
-
-Please try these options and post any problems/successes to me.
