<title>Introduction</title>
<sect1 id="protocol_vs_bus">
<title>Protocol vs bus</title>
<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

</para>
</sect1>
<sect1 id="subsystem_design">
<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.

Scan a host to determine which (if any) devices are attached.
The general scanning/probing algorithm is as follows, exceptions are
made to it depending on device specific flags, compilation options,
and global variable (boot or module load time) settings.
A specific LUN is scanned via an INQUIRY command; if the LUN has a
device attached, a scsi_device is allocated and setup for it.
For every id of every channel on the given host, start by scanning
LUN 0. Skip hosts that don't respond at all to a scan of LUN 0.
Otherwise, if LUN 0 has a device attached, allocate and setup a
scsi_device for it. If target is SCSI-3 or up, issue a REPORT LUN,
and scan all of the LUNs returned by the REPORT LUN; else,
sequentially scan LUNs up until some maximum is reached, or a LUN is
seen that cannot have a device attached to it.

The SAS transport class contains common code to deal with SAS HBAs,

and various sysfs attributes to expose these topologies and managment
interfaces to userspace.

<para>
In addition to the basic SCSI core objects this transport class
introduces two additional intermediate objects: The SAS PHY
as represented by struct sas_phy defines an "outgoing" PHY on
a SAS HBA or Expander, and the SAS remote PHY represented by
struct sas_rphy defines an "incoming" PHY on a SAS Expander or
end device. Note that this is purely a software concept, the
underlying hardware for a PHY and a remote PHY is the exactly
the same.

There is no concept of a SAS port in this code, users can see
what PHYs form a wide port based on the port_identifier attribute,
which is the same for all PHYs in a port.

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.

1. Setting the max_sectors_per_req based on max SGL supported by the
FW. Prior versions calculated this value from controller info
(max_sectors_1, max_sectors_2). For certain controllers/FW,
this was resulting in a value greater than max SGL supported
by the FW. Issue was first reported by users running LUKS+XFS
with megaraid_sas. Thanks to RB for providing the logs and
duplication steps that helped to get to the root cause of the
issue. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from
10. FW may take a max of 60 seconds to respond to the INIT

It does, but the DMA API was expanded to cope with this exact case, so
use dma_alloc_coherent() directly in the megaraid code instead. The dev
is just &pci_dev->dev.

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.

1. Added new memory management module to support the IOCTL memory allocation. For IOCTL we try to allocate from the memory pool created during driver initialization. If mem pool is empty then we allocate at run time.
2. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead
(hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS

The driver registers char device "hptiop" to communicate with HighPoint RAID
management software. Its ioctl routine acts as a general binary interface
between the IOP firmware and HighPoint RAID management software. New management
functions can be implemented in application/firmware without modification
in driver code.

README for WarpEngine/A4000T/A4091 SCSI kernels.
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.
