This update includes the usual round of major driver updates (hpsa, be2iscsi,
 hisi_sas, zfcp, cxlflash).  There's a new incarnation of hpsa called smartpqi
 for which a driver is added, there's some cleanup work of the ibm vscsi target
 and updates to libfc, plus a whole host of minor fixes and updates and finally
 the removal of several ISA drivers which seem not to have been used for years.

README file for the Linux DTC3180/3280 scsi driver.
by Ray Van Tassle (rayvt@comm.mot.com) March 1996
Based on the generic & core NCR5380 code by Drew Eckhard
SCSI device driver for the DTC 3180/3280.
Data Technology Corp---a division of Qume.
The 3280 has a standard floppy interface.
The 3180 does not. Otherwise, they are identical.
The DTC3x80 does not support DMA but it does have Pseudo-DMA which is
supported by the driver.
Its DTC406 scsi chip is supposedly compatible with the NCR 53C400.
It is memory mapped, uses an IRQ, but no dma or io-port. There is
internal DMA, between SCSI bus and an on-chip 128-byte buffer. Double
buffering is done automagically by the chip. Data is transferred
between the on-chip buffer and CPU/RAM via memory moves.
The driver detects the possible memory addresses (jumper selectable):
CC00, DC00, C800, and D800
The possible IRQ's (jumper selectable) are:
IRQ 10, 11, 12, 15
Parity is supported by the chip, but not by this driver.
Information can be obtained from /proc/scsi/dtc3c80/N.
Note on interrupts:
The documentation says that it can be set to interrupt whenever the
on-chip buffer needs CPU attention. I couldn't get this to work. So
the driver polls for data-ready in the pseudo-DMA transfer routine.
The interrupt support routines in the NCR3280.c core modules handle
scsi disconnect/reconnect, and this (mostly) works. However..... I
have tested it with 4 totally different hard drives (both SCSI-1 and
SCSI-2), and one CDROM drive. Interrupts works great for all but one
specific hard drive. For this one, the driver will eventually hang in
the transfer state. I have tested with: "dd bs=4k count=2k
of=/dev/null if=/dev/sdb". It reads ok for a while, then hangs.
After beating my head against this for a couple of weeks, getting
nowhere, I give up. So.....This driver does NOT use interrupts, even
if you have the card jumpered to an IRQ. Probably nobody will ever
care.

UPDATE NEWS: version 1.33 - 26 Aug 98
Interrupt management in this driver has become, over
time, increasingly odd and difficult to explain - this
has been mostly due to my own mental inadequacies. In
recent kernels, it has failed to function at all when
compiled for SMP. I've fixed that problem, and after
taking a fresh look at interrupts in general, greatly
reduced the number of places where they're fiddled
with. Done some heavy testing and it looks very good.
The driver now makes use of the __initfunc() and
__initdata macros to save about 4k of kernel memory.
Once again, the same code works for both 2.0.xx and
2.1.xx kernels.
UPDATE NEWS: version 1.32 - 28 Mar 98
Removed the check for legal IN2000 hardware versions:
It appears that the driver works fine with serial
EPROMs (the 8-pin chip that defines hardware rev) as
old as 2.1, so we'll assume that all cards are OK.
UPDATE NEWS: version 1.31 - 6 Jul 97
Fixed a bug that caused incorrect SCSI status bytes to be
returned from commands sent to LUNs greater than 0. This
means that CDROM changers work now! Fixed a bug in the
handling of command-line arguments when loaded as a module.
Also put all the header data in in2000.h where it belongs.
There are no longer any differences between this driver in
the 2.1.xx source tree and the 2.0.xx tree, as of 2.0.31
and 2.1.45 (or is it .46?) - this makes things much easier
for me...
UPDATE NEWS: version 1.30 - 14 Oct 96
Fixed a bug in the code that sets the transfer direction
bit (DESTID_DPD in the WD_DESTINATION_ID register). There
are quite a few SCSI commands that do a write-to-device;
now we deal with all of them correctly. Thanks to Joerg
Dorchain for catching this one.
UPDATE NEWS: version 1.29 - 24 Sep 96
The memory-mapped hardware on the card is now accessed via
the 'readb()' and 'readl()' macros - required by the new
memory management scheme in the 2.1.x kernel series.
As suggested by Andries Brouwer, 'bios_param()' no longer
forces an artificial 1023 track limit on drives. Also
removed some kludge-code left over from struggles with
older (buggy) compilers.
UPDATE NEWS: version 1.28 - 07 May 96
Tightened up the "interrupts enabled/disabled" discipline
in 'in2000_queuecommand()' and maybe 1 or 2 other places.
I _think_ it may have been a little too lax, causing an
occasional crash during full moon. A fully functional
/proc interface is now in place - if you want to play
with it, start by doing 'cat /proc/scsi/in2000/0'. You
can also use it to change a few run-time parameters on
the fly, but it's mostly for debugging. The curious
should take a good look at 'in2000_proc_info()' in the
in2000.c file to get an understanding of what it's all
about; I figure that people who are really into it will
want to add features suited to their own needs...
Also, sync is now DISABLED by default.
UPDATE NEWS: version 1.27 - 10 Apr 96
Fixed a well-hidden bug in the adaptive-disconnect code
that would show up every now and then during extreme
heavy loads involving 2 or more simultaneously active
devices. Thanks to Joe Mack for keeping my nose to the
grindstone on this one.
UPDATE NEWS: version 1.26 - 07 Mar 96
1.25 had a nasty bug that bit people with swap partitions
and tape drives. Also, in my attempt to guess my way
through Intel assembly language, I made an error in the
inline code for IO writes. Made a few other changes and
repairs - this version (fingers crossed) should work well.
UPDATE NEWS: version 1.25 - 05 Mar 96
Kernel 1.3.70 interrupt mods added; old kernels still OK.
Big help from Bill Earnest and David Willmore on speed
testing and optimizing: I think there's a real improvement
in this area.
New! User-friendly command-line interface for LILO and
module loading - the old method is gone, so you'll need
to read the comments for 'setup_strings' near the top
of in2000.c. For people with CDROM's or other devices
that have a tough time with sync negotiation, you can
now selectively disable sync on individual devices -
search for the 'nosync' keyword in the command-line
comments. Some of you disable the BIOS on the card, which
caused the auto-detect function to fail; there is now a
command-line option to force detection of a ROM-less card.
UPDATE NEWS: version 1.24a - 24 Feb 96
There was a bug in the synchronous transfer code. Only
a few people downloaded before I caught it - could have
been worse.
UPDATE NEWS: version 1.24 - 23 Feb 96
Lots of good changes. Advice from Bill Earnest resulted
in much better detection of cards, more efficient usage
of the fifo, and (hopefully) faster data transfers. The
jury is still out on speed - I hope it's improved some.
One nifty new feature is a cool way of doing disconnect/
reselect. The driver defaults to what I'm calling
'adaptive disconnect' - meaning that each command is
evaluated individually as to whether or not it should be
run with the option to disconnect/reselect (if the device
chooses), or as a "SCSI-bus-hog". When several devices
are operating simultaneously, disconnects are usually an
advantage. In a single device system, or if only 1 device
is being accessed, transfers usually go faster if disconnects
are not allowed.
The default arguments (you get these when you don't give an 'in2000'
command-line argument, or you give a blank argument) will cause
the driver to do adaptive disconnect, synchronous transfers, and a
minimum of debug messages. If you want to fool with the options,
search for 'setup_strings' near the top of the in2000.c file and
check the 'hostdata->args' section in in2000.h - but be warned! Not
everything is working yet (some things will never work, probably).
I believe that disabling disconnects (DIS_NEVER) will allow you
to choose a LEVEL2 value higher than 'L2_BASIC', but I haven't
spent a lot of time testing this. You might try 'ENABLE_CLUSTERING'
to see what happens: my tests showed little difference either way.
There's also a define called 'DEFAULT_SX_PER'; this sets the data
transfer speed for the asynchronous mode. I've put it at 500 ns
despite the fact that the card could handle settings of 376 or
252, because higher speeds may be a problem with poor quality
cables or improper termination; 500 ns is a compromise. You can
choose your own default through the command-line with the
'period' keyword.

In later ROMs (starting with 01.3 in April 1994) sw1-8 controls

MSDOS 5.0 (ignored by Linux):
off = 2 drives maximum
on = 7 drives maximum

------------------------------------------------
I should mention that Drew Eckhardt's 'Generic NCR5380' sources
were my main inspiration, with lots of reference to the IN2000
driver currently distributed in the kernel source. I also owe
much to a driver written by Hamish Macdonald for Linux-m68k(!).
And to Eric Wright for being an ALPHA guinea pig. And to Bill
Earnest for 2 tons of great input and information. And to David
Willmore for extensive 'bonnie' testing. And to Joe Mack for
continual testing and feedback.

SMARTPQI - Microsemi Smart PQI Driver
-----------------------------------------
This file describes the smartpqi SCSI driver for Microsemi
(http://www.microsemi.com) PQI controllers. The smartpqi driver
is the next generation SCSI driver for Microsemi Corp. The smartpqi
driver is the first SCSI driver to implement the PQI queuing model.
The smartpqi driver will replace the aacraid driver for Adaptec Series 9
controllers. Customers running an older kernel (Pre-4.9) using an Adaptec
Series 9 controller will have to configure the smartpqi driver or their
volumes will not be added to the OS.
For Microsemi smartpqi controller support, enable the smartpqi driver
when configuring the kernel.
For more information on the PQI Queuing Interface, please see:
http://www.t10.org/drafts.htm
http://www.t10.org/members/w_pqi2.htm
Supported devices:
------------------
<Controller names to be added as they become publically available.>
smartpqi specific entries in /sys
-----------------------------
smartpqi host attributes:
-------------------------
/sys/class/scsi_host/host*/rescan
/sys/class/scsi_host/host*/version
The host rescan attribute is a write only attribute. Writing to this
attribute will trigger the driver to scan for new, changed, or removed
devices and notify the SCSI mid-layer of any changes detected.
The version attribute is read-only and will return the driver version
and the controller firmware version.
For example:
driver: 0.9.13-370
firmware: 0.01-522
smartpqi sas device attributes
------------------------------
HBA devices are added to the SAS transport layer. These attributes are
automatically added by the SAS transport layer.
/sys/class/sas_device/end_device-X:X/sas_address
/sys/class/sas_device/end_device-X:X/enclosure_identifier
/sys/class/sas_device/end_device-X:X/scsi_target_id
smartpqi specific ioctls:
-------------------------
For compatibility with applications written for the cciss protocol.
CCISS_DEREGDISK
CCISS_REGNEWDISK
CCISS_REGNEWD
The above three ioctls all do exactly the same thing, which is to cause the driver
to rescan for new devices. This does exactly the same thing as writing to the
smartpqi specific host "rescan" attribute.
CCISS_GETPCIINFO
Returns PCI domain, bus, device and function and "board ID" (PCI subsystem ID).
CCISS_GETDRIVVER
Returns driver version in three bytes encoded as:
(DRIVER_MAJOR << 28) | (DRIVER_MINOR << 24) | (DRIVER_RELEASE << 16) | DRIVER_REVISION;
CCISS_PASSTHRU
Allows "BMIC" and "CISS" commands to be passed through to the Smart Storage Array.
These are used extensively by the SSA Array Configuration Utility, SNMP storage
agents, etc.

config SCSI_U14_34F_TAGGED_QUEUE
bool "enable tagged command queueing"
depends on SCSI_U14_34F
help
This is a feature of SCSI-2 which improves performance: the host
adapter can send several SCSI commands to a device's queue even if
previous commands haven't finished yet.
This is equivalent to the "u14-34f=tc:y" boot option.
config SCSI_U14_34F_LINKED_COMMANDS
bool "enable elevator sorting"
depends on SCSI_U14_34F
help
This option enables elevator sorting for all probed SCSI disks and
CD-ROMs. It definitely reduces the average seek distance when doing
random seeks, but this does not necessarily result in a noticeable
performance improvement: your mileage may vary...
This is equivalent to the "u14-34f=lc:y" boot option.
config SCSI_U14_34F_MAX_TAGS
int "maximum number of queued commands"
depends on SCSI_U14_34F
default "8"
help
This specifies how many SCSI commands can be maximally queued for
each probed SCSI device. You should reduce the default value of 8
only if you have disks with buggy or limited tagged command support.
Minimum is 2 and maximum is 14. This value is also the window size
used by the elevator sorting option above. The effective value used
by the driver for each probed SCSI device is reported at boot time.
This is equivalent to the "u14-34f=mq:8" boot option.

/*
* The card is detected and initialized in one of several ways :
* 1. Autoprobe (default) - There are many different models of
* the Pro Audio Spectrum/Studio 16, and I only have one of
* them, so this may require a little tweaking. An interrupt
* is triggered to autoprobe for the interrupt line. Note:
* with the newer model boards, the interrupt is set via
* software after reset using the default_irq for the
* current board number.
*
* 2. With command line overrides - pas16=port,irq may be
* used on the LILO command line to override the defaults.
*
* 3. With the PAS16_OVERRIDE compile time define. This is
* specified as an array of address, irq tuples. Ie, for
* one board at the default 0x388 address, IRQ10, I could say
* -DPAS16_OVERRIDE={{0x388, 10}}
* NOTE: Untested.
*
* 4. When included as a module, with arguments passed on the command line:
* pas16_irq=xx the interrupt
* pas16_addr=xx the port
* e.g. "modprobe pas16 pas16_addr=0x388 pas16_irq=5"
*
* Note that if the override methods are used, place holders must
* be specified for other boards in the system.
*
*
* Configuration notes :
* The current driver does not support interrupt sharing with the
* sound portion of the card. If you use the same irq for the
* scsi port and sound you will have problems. Either use
* a different irq for the scsi port or don't use interrupts
* for the scsi port.
*
* If you have problems with your card not being recognized, use
* the LILO command line override. Try to get it recognized without
* interrupts. Ie, for a board at the default 0x388 base port,
* boot: linux pas16=0x388,0
*
* NO_IRQ (0) should be specified for no interrupt,
* IRQ_AUTO (254) to autoprobe for an IRQ line if overridden
* on the command line.

---help---
This driver supports Microsemi PQI controllers.
<http://www.microsemi.com>
To compile this driver as a module, choose M here: the
module will be called smartpqi.
Note: the aacraid driver will not manage a smartpqi
controller. You need to enable smartpqi for smartpqi
controllers. For more information, please see
Documentation/scsi/smartpqi.txt
