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.
