The changes deal with software debouncing apparently necessary on
todays faster hardware, and also some problems with the use of the -Select

will be removed.

change that might be visible to drivers is, that the type pcici_t

should not be relied on), has been converted into a pcicfgregs* .

A new generic device descriptor data type has to be agreed on. The PCI

be (eventually) architecture independent. It provides an emulation
of the ISA interrupt registration function register_intr(), but that
function does no longer manipulated the interrupt controller and
interrupt descriptor table, but calls the architecture dependent
function setup_icu() for that purpose.
After the ISA/EISA bus code has been modified to directly call the new
interrupt registartion functions (intr_create() and intr_connect()),
the emulation of register_intr() should be dropped.
The C level interrupt handler function should take a (void*) argument,
and the function pointer type (inthand2_t) should defined in some other

1) i586_bcopy() problem
There have been a number of reports that the syscons doesn't work
properly if i586_bcopy() is enabled.
The problem prevented users from installing 2.2(.1)-RELEASE. The
symptom is that the system looks frozen during device probe or just
before the main installation menu. The workaround was to specify the
flag 0x01 to the npx device so that i586_bcopy() is disabled.
The patch forces the syscons to call generic_bcopy() when copying
to/from the video memory, even if CPU is Pentium and i586_bcopy() is
enabled. i586_bcopy() is still called for copy operations between
non-video memory regions.

2) video mode parameter table problem
The syscons reads and uses the video mode parameter table provided by
the VGA BIOS to set VGA registers when changing video mode and
modifying font data. It appears that in some VGA BIOSes the table is
not ordered as the syscons expects, and this leads to screen
corruption.
The problem prevented users from installing 2.2(.1)-RELEASE. The
symptom is the corrupt screen or strange vertical lines soon after the
kernel is loaded into memory (just after the kernel decompression).
The patch performs simplistic test and if it fails, set video_mode_ptr
to NULL so that the video mode switching won't happen.
This is an interim kludge. There should be a better way to deal with
the problem.

Bump the timeout for an "ordered tag" recovery action from 1 to 5 seconds.
Remove the multiple timeout panic. Its very easy to get into a situation
where a timedout command will time out a second time even though the
recovery code is working fine. A good example is:
1) Command times out during recovery
2) reset the timeout for the command
3) Recovery actions complete and all transactions are requeued
4) second timeout fires off which puts us back into recovery bogusly
5) another transaction that timedout once during the first recovery action
times out causing the panic.
In essence, the correct solution to the problem is to put every transaction
back up into the work queue and have their timeout handling done in the same
way that all commands are handled. The CAM layer makes this easy, so it
will have to wait until then.

So far, there have been two independent reports from Dell Latitude XPi
notebook/laptop owners. The Latitude seems to be the only system which
suffers from this problem. (I don't know the problem is with the
entire Latitude line or with only some Latitude models) No problem
report has been heard about other systems (I certainly cannot
reproduce the problem in my -current and 2.2 systems).
In 3.0-CURRENT, 2.2-RELEASE and 2.2-GAMMA-970310, when programming the
keyboard LED/repeat-rate, `set_keyboard()' in `syscons' tells the
keyboard controller not to generate keyboard interrupt (IRQ1) and then
enable tty interrupts, expecting the keyboard interrupt doesn't occur.
It appears that somehow Latitude's keyboard controller still generates
the keyboard interrupt thereafter, and `set_keyboard()' doesn't see
the return code from the keyboard because it is consumed by the
keyboard interrupt handler.
The patch entirely disables tty interrupts while setting LED and
typematic rate in `set_keyboard()', making the routine behave more
like the previous versions of `syscons' (versions in 2.1.X and
2.2-ALPHA, -BETA, and some -GAMMAs). The reporter said this patch
eliminated the problem.

Allow commands with SDTR and WDTR negotiation to be tagged. The SCSI II spec

The driver did this in the past for almost two years without any problem,

as the number of openings is higher than two and we'll start sending it
tagged commands causing "overlapped commands attempted" type errors. The

I have code to calibrate the overhead fairly accurately, but there
is little point in using it since it is most accurate on machines
where an estimate of 0 works well. On slow machines, the accuracy
of DELAY() has a large variance since it is limited by the resolution
of getit() even if the initial delay is calibrated perfectly.
Use fixed point and long longs to speed up scaling in DELAY().
The old method slowed down a lot when the frequency became variable.
Assume the default frequency for short delays so that the fixed
point calculation can be exact.
Fast scaling is only important for small delays. Scaling is done
after looking at the counter and outside the loop, so it doesn't
decrease accuracy or resolution provided it completes before the
delay is up. The comment in the code is still confused about this.
- don't uselessly initialize the fifo "DMA" bit at attach time.

- don't uselessly initialize the fifo trigger level to 8 (scaled to
256) at attach time.
- don't scale the fifo trigger level to 512 bytes. The driver's pseudo-
