to hard wire the unit numbers (and have high unit numbers for plug

cards not migrate from aha1 -> aha0 should aha0 go on the fritz. I
didn't verify that hard wired scsi busses would work, but did verify
that hard wired aha addresses did work to a limited extent. Both
aha0 and aha1 must be hardwired, or when the card that was in aha0
goes away, the probe for aha0 might pick up the card that otherwise
would have been aha1.

in cyopen() were done in a different order than in sioopen(), partly
to (ab)use a side effect of comparam() and partly because I didn't
understand what the reset was doing (it flushes the fifos). This
turned out to be more than a cosmetic problem. Flushing the fifos
quite late is good for discarding input that arrived while the line
state was being initialized, and in the cy driver it also seems to
reduce a problem with input that arrived long ago during the previous
close (the UART loses sync too easily and for too long).
The optimisation of only waiting before issuing new commands is
obviously invalid in general and it caused many errors in NIST-PCTS.
I think the errors were mostly for characters sent with the wrong
parity, etc., after a half complete tcsetattr().
Use microtime() instead of a magic loop count to limit the wait.
The wait is a busy-wait :-( and normally takes about 500 usec.
almost works properly. Unfortunately, there is no way to flush
the rx fifo without resetting the channel, which also flushes the
tx fifo. We avoid resetting even when both fifos need to be flushed,
since resetting seems to cause the rx to lose sync if it is done
while data is arriving.

It differs from a normal floppy in that you must use PIO rather than
DMA to transfer the data.
To enable this, you must add options "FDC_YE" to your kernel. I don't
have a machine that has a floppy and a pcmcia slot to test to make
sure that this doesn't impact normal floppy units, so I've left this as

The right answer is to let the PCI system know that the attach failed,

use a 256 entry ring buffer of descriptersfor this purpose. This allows
the use of a simple 8bit counter in the sequencer code for tracking start

Entries in the ring buffer now contain a "cmd_valid" byte at their tail.
As an entry is serviced, this byte is cleared by the kernel and set by
the sequencer during its dma of a new entry. Since this byte is the last
portion of the command touched during a dma, the kernel can use this
byte to ensure the command it processes is completely valid.
The new command format requires a fixed sized DMA from the controller

fxp_stop is called as the first thing in fxp_init, and if the tx desc
list has junk in it, the system may panic. This bug showed up as a side
effect of the changes in rev 1.56, but has been in the code since the
beginning.
this myself for ages, but wasn't able to get any feedback from the people
that I sent it to for testing.
Guy Helmer <ghelmer@scl.ameslab.gov> has given it a shot (before getting on
a plane, thanks!) and it appears to stop his reproducable page fault panic
in the testing he was able to do.
o For bt and aha only probe the one I/O range if a specific I/O is specified
in the config file.
o Don't even try to probe I/O ranges that have been seen already.
o If we conflict with an IRQ or DRQ, then fail the probe.

is a work-around from an LRAM access bug on the 940UA. In a future
microcode revision, the high 16bits of residual information will be moved
to a safe location and we'll return to 32bit residuals. Since we only
allow 64KB I/O, 16bits is enough.

a similar treatment, and many more that should be converted to plain
log messages (e.g. "WARNING: wrintr but write DMA inactive!"). Now
that I think of it, same goes for the CAM code (e.g. the famed "tagged

Parity checking is broken for some chip/MB combinations and this

Also present here are apm hooks so that laptops can properly
reconfigure the hardware after suspend (tested on the Libretto50).

- Express various sizes in bytes, rather than Kbytes, in the video
mode and adapter information structures.
- Fill 0 in the linear buffer size field if the linear frame buffer
is not available.
- Remove SW_VESA_USER ioctl. It is still experimetal and was not meant
to be released.
- Fix missing cast operator.
- Correctly handle pointers returned by the VESA BIOS. The pointers
may point to the area either in the BIOS ROM or in the buffer supplied
by the caller.
- Set the destructive cursor at the right moment.
o Use the board id command to find out what kind of board
we're talking to. If we're talking to a board that is has
an ID that is shared between boards supported by the aha
driver and the bt driver, then use the bt's geometry
register to weed out the bt cards. Otherwise assume that we
support this card.
o Remove bt esetup command sending to the card. It seems to
wedge too many cards.
o Revert to doing a soft reset after an invalid command. This
change didn't fix anything, so I'm backing it out. The
whole issue of card resetting needs to be revisisted at some
point so that we can do it properly on all hardware.
o GC unused stuff in some places.
o Unlock mailbox interface if we have a new card. Before only newer cards
(B or newer) that had the BIOS disabled would probe. Cards with the
BIOS enabled would fail to probe in the mailbox initialization code.
o Increase the number of ccbs and sg to 17 from 16 to support 64k I/O
on a non page aligned boundary. Ideas for dynamic determination of this
value welcomed, as more of these are better.
o Took credit for this driver, even though I derived it from Justin's code.
Made sure that Justin's copyright from bt.c was preserved, along with
his name, since the error handling code is nearly identical. Add my
own, identical copyright. Point people to aha_isa.c.
Cards tested: 1542C and 1542CF. The B and CP might work now as well,
but logistical problems precluded me from testing them this evening

- there were too many global variables (there still are :-).
- the data section was bloated by explicit initializations of static
variables to 0 (only fixed the recently changed ones).
- WRAPHIST() had silly parentheses around foo->bar.
- the comment about inline functions was stale.
- the comment about Userconfig presumes too much about the boot environment.
- `i' was reused confusingly in scioctl().
- the declaration of `butmap' used a deprecated K&R misfeature.
- the initializeation of `butmap' had an unnecessary line break.

- Define generic text mode numbers so that the user can just give
"80x25", "80x60", "132x25"..., rather than "VGA_xxx", to `vidcontrol'
to change the current video mode. `vidoio.c' and `vesa.c' will map
these numbers to real video mode numbers appropriate and available
with the given video hardware. I believe this will be useful to make
syscons more portable across archtectures.
Bump the lun field in the eata ccb to 5 bits. We still only

In dpttimeout, expect that the controller will complete aborted CCBs through
the interrupt handler. This corrects a panic that was caused by completing
the same transaction twice during timeout recovery.
Honor the tag times types expressed by the user and pass them down to

Eradicate some silly uses of u_int8_t that just serve to slow the code down.
+ Change some messages about CCB memory allocation
+ Turn a failure to DMA map all of a transaction due to lack of
ISP queue entries into a requeue operation (instead of the
case where it had been treated the same as a DMA too big
operation).
+ put back splsoftvm around bus_dmamap_load calls.
+ cleanup (and fix a glaring bug) in the and of the dma setup
routine. Also, the dma setup routines either return CMD_QUEUED
(for success) or CMD_COMPLETE (for failure) or CMD_EAGAIN
(for requeuing for resource shortage reasons).
