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.
(I also found another typo/bug, but the reporter and I found that it
wasn't the cause of the problem...)

I broke the cable tuning with my 'TEST_A' code. Remove TEST_A define

Thanks to Justin Gibbs for providing a PCI bus analyzer trace while the
Intel Windows driver was configuring the board...this made it possible
to figure out the mystery bit that I wasn't setting in the PHY for full
duplex to work.
devtotty(). devtotty() must check its arg carefully since the arg is

Renamed devtotty() to snpdevtotty().
New sequencer assembler for the aic7xxx adapters. This assembler
performs some amount of register type checking, allows bit
manipulation of symbolic constants, and generates "patch tables"
for conditionalized downloading of portions of the program.
This makes it easier to take full advantage of the different
features of the aic7xxx cards without imposing run time penalies
or being bound to the small memory footprints of the low end
cards for features like target mode.
aic7xxx.reg:
New, assembler parsed, register definitions fo the aic7xxx cards.
This was done primarily in anticipation of 7810 support which
will have a different register layout, but should be able to use
the same assembler. The kernel aic7xxx driver consumes a generated
file in the compile directory to get the definitions of the register
locations.
aic7xxx.seq:
Convert to the slighly different syntax of the new assembler.
Conditionalize SCB_PAGING, ultra, and twin features which shaves

Add code to leave the selection hardware enabled during reconnects
that win bus arbitration. This ensures that we will rearbitrate

When we expect the bus to go free, perform all of the cleanup
associated with that event "up front" and enter a loop awaiting
bus free. If we see a REQ first, complain, but attempt to
continue. This will hopefully address, or at least help diagnose,
the "target didn't send identify" messages that have been reported.

time that we really want to do this is when a bus reset causes the sequencer
to be reset and the kernel driver now handles this case.
Remove some reordering in the select2 routine that wasn't necessary.
It was an experimental fix for a race condition I fixed elsewhere, and
confused the code flow.
Don't bother looping on a parity error in the mesgout loop since we can't
see parity errors on out phases.
Clean up the mesgin_identify code. In the old days, we "snooped" for tag
messages and used this as an indicator of whether or not the target was
using tagged transactions. This forced the sequencer to ack the identify
before determining if a valid SCB matched the target meaning that an abort
message to handle this case might not be seen before the target entered a
data phase. Since we can determin the "tagged-ness" of a target by looking
it up in the array of busy targets (recently introduced), we can determine
this up front simplifying the search code as well as ensuring we can follow
the SCSI specs method for rejecting a reselection.
When an SCB is placed on the free list, set its SCB_TAG to SCB_LIST_NULL.
This makes it much easier for the kernel driver to find active SCBs on the
card during error recovery.
negotiation messages may be tagged, we were overrunning the old buffer.
The variable that was getting squashed is updated before the message goes
out, causing corrupted SDTR or WDTR messages. Depending on the phases
traversed before message out, this could cause the wrong offset to be
negotiated allowing data overruns to occur. The problem is easier to
detect with wide targets on the chain since the allowed offset is smaller.
Also removed the unnecessary clearing of SPIORDY during the message out
phase. We don't rely on SPIORDY any more.
When setting the HCNT registers, do so in ascending order.
When performing tagged queueing in non-paging mode, also check the
disconnected bit in the SCB as extra sanity during a reconection.
Make the labels in the DMA routine more sane.
When doing a DMA, if we see the DMADONE condition come true, we can
simply turn of the DMA enable bits in DFCNTRL without testing the FIFO
state as HDONE is true when DMADONE is true and this emplies the FIFO is
empty.
These changes clear up the data overrun error messages and seem to prevent
the "timed out in data-in phase" problems.

Add implicit support for the NOOP message. I've never heard of the driver

In the dma routine, check SDONE before cleaing SDMAEN. The data books mention

- don't uselessly initialize the fifo "DMA" bit at attach time.

- don't uselessly initialize the fifo trigger level to 8 (scaled to

- don't scale the fifo trigger level to 512 bytes. The driver's pseudo-

In the data phase dma handler, mask off just the enable bits instead of

Also don't stop a DMA until MREQPEND goes false. Doing this may cause

Add definitions for MREQPEND and the BRDCTL register. The BRDCTL register

Only enable reselections once the channel and SCSIRATE have been cleared.
Add a pause block around the test busy code in the non-tagged case to simplify

Simplify reselection processing by removing the call to initialize_scsiid.
Clear the scsiseq re/select control bits and setup for catching bogus

Improve the automatic PIO code. It turns out that SPIORDY is not a reliable
hardware condition bit, so use REQINIT intstead. Don't rely on PHASEMIS
either since it can take too long to come true. Use a brute force comparison
instead.
Remove some unnecessary overhead in the command complete processing. It
should be nearly impossible to overflow the QOUTFIFO (worst case 9 command
have to complete with at least 6 of them requiring paging on an aic7850),
so don't take the additional PIO hit to guard against this condition. If we
don't see our interrupt in time, the system has bigger problems elsewhere.
If this ever does happen, the timeout handler will notice and retry the
command.

cur_console is NULL when copy_font() is first called from scinit(). This
is apparently harmless when scinit() is called early from sccninit() -
page 0 is apparently mapped r/w then, and 0->status contains suitable
garbage. However, when there is a serial console, scinit() is first
called from scattach() when the page tables are completely initialized,
so the NULL pointer causes a panic.
