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.
