-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.

- 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.
