* support chip clocks != COM_FREQ, by introducing sc_frequency (for the
mainline code) and adding a frequency parameter right after the rate
parameter to comcnattach() and com_kgdb_attach().
- Make com_isa and com_multi initialize sc_frequency to COM_FREQ.
- Make i386/machdep.c and alpha/dec_xxx.c call com*attach() with the freq.
parameter.
* supio_attach_args get two more fields: a sc_ipl and a sc_arg, both ints.
- com_supio uses the first for interupt establishment (all childs will, as
soon as they exist) and the 2nd for sc_frequency.
- drsupio passes sc_ipl alway as 5, and for the "com"s, sc_arg as 16*115200
- hyper will pass sc_ipl as 6, and sc_arg as 16 * 460800

Thanks to Geoff Wing <mason@primenet.com.au> for testing this on his hardware.
I also made inclusion of LPRINTF() dependent solely on the symbol
LPTDEBUG, initialized lptdebug variable to 0 instead of 1, and
matched arguments to format strings in LPRINTF() calls.
looking what's the autoconfig do on strange harware, and ATAPI_DEBUG2 is
for debuging data transfers (and is really verbose once the machine has booted
from an IDE disk).
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.
at the same time instead by using two different calls. This enables
it to check more easily if the combined mode is all right.
- Improve the error checking in audio.c.
- Add a new audio property, AUDIO_PROP_INDEPENDENT, show if the
play and record settings are independent.
- Fix some buglets in audio.c.
-put all early console / KGDB initialization into 1 exported function
(com_*_attach()) each, dont use global variables anymore
-use the passed tcflag_t for port settings instead of hardwiring 8N1
-at autoconfiguration attach time, decide if the attaching device is
already console / KGDB by comparing bus tag and base addr (cgd's wish)
-export a function "com_is_console()" for use by driver frontends for
this comparision
-delay setting of cn_tab->cn_dev until autoconfiguration attach
to get the minor number right
-delete unused comcnprobe() and comcninit()
-Separate KGDB port initialization and softc related stuff to allow
KGDB to be attached in early system startup, before autoconfiguration.
-Export the variables needed by md code to hand-craft bus tag/handle.
-Fix initialization to enable interrupt by line break.
-Call DDB/KGDB at line break (move DDB call from the softirq handler
to the hard handler because it should work without a tty attached too).
a command to the 82586 for every frame to be transmitted. Instead, a
single command sets off the execution of a chain of commands consisting
of alternate XMITs and NO-OPs, where the link fields in the NO-OPs are
set to loop back onto themselves until the next XMIT is ready to go.
This trick found on a Linux WEB page.
All this induces reasonable transmission performance in my old multibus
adapter. The receiver performance is still abysmal..
- Change the way attach and open works to allow multiple audio
devices.
- Split the mulaw.c file into two to avoid dragging in mulaw
convertsion when they are not needed. Add 16 bit alaw/mulaw tables.
- Change the way audio properties are gotten.
- Recognize more versions os SoundBlaster.
- It is now possible to handle devices that want "looping" DMA,
e.g. the SoundBlaster correctly. The WSS and SB drivers use this.
To do this several new methods were introduced in audio_hw_if.
- Different silence handling (forced by previous change).
- The audio driver can now be mmap()-ed, but due to problems in
the VM system only for writing for now.
- The OSS (Linux) audio emulation takes advantage of some of the
new features.
zero. We use this later when the COMPLETE message comes in to set the
final residual count to zero. The flag is reset if the target resumes
a data phase. This obsoletes the `AUTOSAVE' quirk (for this driver).
Also, avoid overwriting the residual count if a SENSE was appended to
the current transaction.
'inline' as well as static. mark prototypes for static inline functions
as possibly unused (with __attribute__ ((unused))), to avoid generating
warnings when compiling without optimization but with most ports'
default warning flags. Clean up prototype list spacing, and make it more
consistent.
connect to their 1-wire bus like the DS2404 "EconoRAM Time Chip"

* Interface function definitions for this kind of chips. Currently only
low-level byte_read and _write, implenented as inline functions.
This functions take a struct ds_handle * (also defined here), which contains
pointers to bit-read/write and reset functions.
Eventually, prototypes for memory-access functions should go here, and the
1-wire bus should be made a BSD auto-configuration bus.
(a) The interrupt is a RESEL interrupt, and
(b) our state is SELECTING.
This condition can occur in perfectly normal operation if we are using
DMA to select the target and we are interrupted by another target
reselecting us. Per discussion with Paul Krannenburg.
Every ccb locks 64k of memory for dma buffers.
Instead of AHA_CCB_MAX ccbs using 1MByte only sc_link.openings ccbs
per device are allocated. Thus we now use only 128KByte per device present.
clock rate for this board on Alpha/PCI systems. Under x86/PCI, the
board f/w will correctly tell you "I'm running at 60Mhz", so the code
that preserved that across a board reset (which would drop the chip
back to 40Mhz) worked fine. On the 8200, the chip was saying "I'm 40Mhz"-
which wasn't true. This turned out to be okay as long as you didn't have
any FAST or UltraFast targets- In fact, setting the chip to 40Mhz allowed
you to run up to 8Mhz SCSI. Unfortunately you die bigtime on the devices
that go faster than that. The fix here is to only use what the chip tells
you the clock rate is in the cases you don't really know (sbus is the
only case where this could be different, although with 66Mhz PCI coming up,
this may change).
(1) fix a printf format (%x to print int, not %lx).
(2) fix probe of 4th chip/16th channel (used to tell whether or not the
board is a 16- or 32-port board) by removing an incorrect offset so
that the code matched its comments. (!!!)
(3) fix storage of chip number in per-channel structure so that it actually
stores the chip number, rather than the chip offset. This allows the
driver to work with more than the first four channels (i.e. with chips
other than chip number 0, which happens to have an offset of zero). (!!!)
MESSAGE_REJECT in response to SDTR or WDTR. Because of this, the
printfs that indicate refusal of sync/wide negotiation are unneeded
in normal operation. In the __NetBSD__ case, disable them by default.
They, like the other extra-verbose ahc driver boot messages, may be
reenabled with "options DEBUG". The behavior in the !__NetBSD__ case
is unchanged.
Set the encoding parameters slightly differently.
Remove the SW encoding/decodinf functions from this interface
and move them to the audio_parameter struct; this is both more efficient
and flexible.
This allows the front end to override the default DCR (byte-wide DMA,
x86 byte order, 8-byte FIFO) with different transfer size, byte order, DMA
parameters, and FIFO threshhold. If the loopback select bit is not set for
normal operation, the default is used instead.
Inspired by thoughts from Bernd Ernesti.
* epinit() had both explicit xcvr selection for 3c589 and a call
to epsetmedia(). The first is redundant; delete it, and EP_COAX_DEFAULT.
* Update comments to reflect 3c589 and 3c509B fixes. Fix typos.
this code makes equal sense for memory and I/O space, prefer to map
the PCI front end via memory space (conditionalized on a patchable kernel
variable), and do a bit of other random NetBSD-specific cleanup. (These
changes were sent to Justin Gibbs on March 28.)
in reset. If none there, try and get from the bus/platform specific code.
If a nonzero value for either, set the clock rate. This is why the PCI
card versions weren't working- they need to be set at 60MHZ, rather than
the default 40MHZ (which worked fine for the internal ISP chips on the
Alpha 8X00).
B) If a isp_poll returns failure (command never completed) to the caller
and no error is set in the xs struct, set XS_SELTIMEOUT. And then call...
C) Added isp_lostcmd function to try and ask the ISP chip about it's current
state as well as the state of commands for a particular target/lun. This is
going along to try and figure out why the very first command to the ISP always
seems to get swallowed up.
byte comparisons. Compare the ethernet addresses backwards on the
assumption that address number byte 6 has the most random distribution,
so packets not for us spend the least time in here.
we return from the driver expecting to come back due to an
interrupt, because the interrupt might not happen...
Do the untimeout in ncr53c9x_done instead of just before
almost every call to ncr53c9x_done as was done previously.
Make ncr53c9x_sense schedule its own timeout for the new
command it is starting (request sense), separate from the
timeout for the command that just completed.

particularly older ones, don't do a SAVE DATA POINTER before disconnecting.
When the driver reconnects, it does an implicit RESTORE POINTERS, and
restores the data pointer from *before* the last transfer. If the driver
calculates the residual using the data pointer and doesn't account for
this, the residual will be wrong.
What we do is test for the SDEV_AUTOSAVE quirk when we see a disconnect
message, falling through to do a SAVE DATA POINTER if the quirk applies
to this target.
The workaround was suggested by Mycroft, who also provided the explanation
of the problem. Actual code was (mostly) ripped off from the 53C9x driver.
Anne Hutton <hutton@isi.edu>]:
- add support for Adaptec 155 PCI ATM cards (e.g. ANA-5940)
- add sc->is_adaptec to handle differences between cards.
- break out MID_MK_TXQ/MID_MK_RXQ seperate macros to handle
the new Adaptec format TXQ/RXQ.
- adjust en_dqneed to return 1 on ADP (since the Adaptec can
DMA anything in one DRQ/DTQ!)
- add hook for a bus specific reset function (adaptec has
a seperate reset register that needs to be hit when
resettting the midway).
- adjust DMA test to not worry about burst sizes on the
adaptec (since it handles it all for us!) and to handle
the new DTQ/DRQ format.
- add Adaptec DMA support to en_txlaunch() and en_service()
BUG FIXES:
- fixed receiver panic under heavy load ("lost mbuf in slot 0!").
when the reassembly buffer overflows, the T-bit is set in
the RDB and the data field is empty. en_service() sets up
a 4-byte (RDB size) dummy DMA without IF_ENQUEUE. but the
recv intr handling in en_intr() always does IF_DEQUEUE.
as a result, a successive recv intr loses its mbuf and
leads to a panic. the solution is to only IF_DEQUEUE if
the interrupt has non-zero length (indicating that there
is an mbuf to get). in order for this to work, EN_DQ_MK
must always be non-zero. we do this by or'ing in an unused
bit (0x80000).

- fix setting of transmit channel when txspeed[] is non-zero
(e.g. traffic shaping). the old scheme didn't work
properly (it allowed the same VCI to use multiple tx channels
thus defeating the txspeed[] parameter). the new scheme
statically assigns a VC to a channel when txspeed[] is set.
[note that the code to set txspeed[] isn't in the driver right
now since a MI interface to do this hasn't been made yet]
we add sc->txvc2slot[] and sc->txslot[n].nref for this.

- when doing SRAM copies, be sure to round up the length to the next
largest word (otherwise the driver will try to do a byte clean
up DMA and then get an ID error interrupt).
MINOR CLEANUPS:
- clean up loops in DMA test
contributed by: Kenjiro Cho <kjc@csl.sony.co.jp>
- restructure and cleanup of en_read/en_write macros/inlines
- clean up some byte ordering stuff so that we are consistant throughout
the driver
Thanks to Michael Smith for reporting, Jason Thorpe for pointing to the
report, doing a quick workaround which pointed me to the right code part and
for testing the final fix.
does not supply media types, default to the "manual" type.
- Clean up the ETHER_CMP stuff slightly.
- Keep track of our carrier status, for media status requests.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.
For the detailed change history, look at the commit log entries for

the base address. This allows for a more flexible layout of buffers
in the Lance's memory.
- Add a new element 'sc_saved_csr0' to am7990_softc. It's value is or-ed
with the current csr0 value in the am7990_intr() function. This allowes
for a 'deferred' interrupt sceme.
