59129515bb Finalize the isa/lpt.c split:
The isa attachment code is in isa/lpt_isa.c now, which attaches to the
already created ic/lpt* files.
You don't need to change your config files, but you need to re-"config" if
using lpt at isa.
XXX The "lpt" device definition should be in sys/conf/files instead, but to
my knowledge, there are some ports which have private copies of lpt, and would
choke on that. No need to make people unhappy 7 days before release branching.

d3a7613827 midway update:
[1] add EN_ENIDMAFIX - the byte-aligner on the ENI version of the card
	appears to lose under heavy load so avoid using it.  see comment
	in midway.c for full details.

	note that the Adaptec version of the card works properly under
	load.

	detected by Kenjiro Cho <kjc@csl.sony.co.jp> [confirmed by chuck]
	fix by chuck & kjc

[2] update some freebsd specific code [from kjc]

[3] for circular buffers: ensure there is always one free slot so
	that we can easily tell the difference between a full and
	empty list.   re-structure a few loops to reflect this.
	fixes a problem with mbufs being free'd while still in DMA,
	and makes drive a bit more robust.

718fb97e11 Support for the upcoming NetBSD/Amiga Hypercom driver family:
* 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

4fea3b463a Provide an alternative method of transmitting frames that avoids sending
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..

68d184dc19 Hmm- seriously funny and sad bug: you need to directly establish the
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). (!!!)

da1b5f9021 It's perfectly normal for an older (e.g. pre SCSI-2) device to send
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

This allows the front end to override the default DCR (byte-wide DMA,

ddc693c299 A) Attempt to get clock rate from ISP chip prior to bashing it over the head
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.

b316767c92 Work around an ambiguity in the SCSI spec. Some implementations,
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.

63c14f2d75 MAJOR CHANGES: [contributed by Chuck Cranor <chuck@ccrc.wustl.edu> and
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).
                  reported by: Kenjiro Cho <kjc@csl.sony.co.jp>

   - 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.
                  reported by: Kenjiro Cho <kjc@csl.sony.co.jp>,
                                  Milind M Buddihikot <milind@ccrc.wustl.edu>,
                                  Dong Lin <dong@eecs.harvard.edu>

   - 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

c7cec27edf Move if_ep media-sense code from front ends to inside back end,
to prepare for if_media, and to support EISA 3c59x cards:

  * change epconfig() to take a short that encodes the chipset
    type (3c509, or Demon/Vortex/Boomerang).
  * add  distinct 3c509 and Demon/Vortex/Boomerang media-sense
    functions to back end.
  * Add EISA match/attach support for the 3c592 and 3c597
    (Demon) cards as well as the 3c509-comatibl EISA 3c509/3c579.

  * Assume that ISA and ISA PnP cards are 3c509-style, until
    proof to the contrary (e.g. large packet support).

Tested on 3c595, 3c590, and 3c509b. Not tested on 3c515 or Demon.

4fdff0ed65 * Add ep_complete_cmd() function, to issue commands that perform a reset
(RX_RESET, TX_RESET, GLOBAL_RESET).
  Commands issued while a reset is in progress may be dropped. The driver
  must wait until resets are complete; ep_complete_cmd() does so.
* Change RX_RESET,  TX_RESET, GLOBAL_RESET to use ep_complete_cmd().

* Revert epconfig() to use inline RX_RESET, TX_RESET.
  That avoids accidentally setting IFF_UP, which  breaks both diskless boot,
  and "halt" commands issued before the interface is brought up.

b1e0c7d657 Print the memory size on startup.
Add newline to `Interface disabled' printf and clean up formatting.
Change packet read/write code to align all reads and writes into
memory to an appropriate boundary for the I/O size. This also fixes
a bug where the trailing unaligned bytes (1-3 of them) would be
put in an additional mbuf even if there was enough space for them
in the one we were currently filling.
This has been tested on a 3c905 in an Alpha (32-bit I/O, alignment
required), a 3c905 in an i386 (32-bit I/O, alignment not required)
and a 3c509 in an i386 (16-bit I/O, alignment not required). It
should be tested on a 3c509 in an Alpha with an ISA bus, if somone
can manage to get the two items together.
There are still some bugs in the driver relating to initialisation;
on my Alpha with a 3c905 you need to do an `ifconfig ep0 down;
ifconfig ep0 up' after the initial ifconfig to make it start working.
Apparently there are also some problems with a 3c579 in an i386,
although a 3c905 in an i386 works just fine.

ae805c5cbf midway fixes:
1. fix possible hang in en_txlaunch().   when attempting to extend
	the length of an mbuf to avoid a flush we should extend it
	by cnt [which is ((need - len) % 4)] rather than 4 - cnt.
	also, add an EN_DEBUG printf() when we pad/FLUSH a buffer
	to help with debugging/understanding what the driver is up to.
  2. use interface packet counters
  3. when turning off a recv VCI we recompute the new mode.   make sure
	we don't include the "in service" bit in the new mode, otherwise
	a VCI may appear "hung" if you turn it off while a service
	interrupt is pending.
  4. when shutting down a VCI that is still receiving data, don't bother
	going into "drain mode" if only the hardware in service bit is
	set (otherwise the VCI may get "hung" in drain mode).
	as a result of this we may get "unexpected rx interrupt" messages
	which are not really an error, so put this printf in EN_DEBUG.
  5. be sure to zero txspeed[lcv] when enabling a VCI (start at full
	speed).   (hooks for setting txspeed[] are currently not in
	the driver, but we are playing with it locally).

16d760f318 Fix for hanging 3com ``large packet'' (100Mbit) Etherlink-III devices:
* Add a slot in the softc, ep_pktlenshift, to indicate that
    a board implements ``large packets'' (FDDI-sized frames) and
    therefore implicitly shifts the argument to packet-length commands
    by two bits to fit a 13-bit length in  an 11-bit command argument field.

 *  Change  the reset of station-mask filterto be independent of bus-type
    (e.g.,. for 3c515)

 * Replace  the "2044" constant used to disable TX threshold interrupts
   on 3c509-generation cards with a #define. Use 2047 instead,
   since that works on the large-packet cards (Vortex, Demon, Boomerang)
   and 2044 doesn't.

 *  Add code to  epconfing to probe for large-packet support,
    set the softc appropriately, and  shift packet sizes in commands
    by ep_pktlenshift to compensate  for the implicit shift.

 *  Tweak the epconfig() code to avoid hanging on startup.
    Set the Tx threshold to interrupt when there's space for
    a maximal-sized ether frame, then  do epinit() then epstop(),
    instead of just the Tx and Rx reset. Required on at least a 3c595.

Tested on  a 3c595, but not on 3c509-generation hardware.

* Add call to bha_pci.c to disable the ISA-compatible ports of a PCI
  device.  The ISA-compatible ports are enabled by default, which
  causes the card to be autoconfigured a second time as an ISA device,
  which appears to deadlock the card.

* Change bha_cmd() to return the number of bytes it actually received
  in response to a command, or -1 on error.

*  Use heuristics (checking for bha-only registers, and checking the size
   of the response to BHA_INQURE_EXTENDED) to bha_find, to make sure the
   bha driver never matches an aha (Adaptec    1542 or compatible) device.

dev/ic/aic7xxxreg.h:
  Remove intrinsic knowledge about SDTR and WDTR messages and replace it
  with a generic message system that allows the kernel driver to handle
  SDTR, WDTR and any other type of extended message it chooses too.  This
  makes the sequencer code much simpler, makes extended message handling
  debuggable since the bulk of the work is in the kernel driver, and saves
  lots of instruction space.

  Regen microcode header file.

dev/ic/aic7xxx.c, dev/ic/aic7xxxvar.h:
  Add code to handle WDTR and SDTR negotiation in light of the changes in
  the message interface to the sequencer.  Don't reject targets that
  negotiate async by sending an SDTR with a 0 offset.  Use an sdtr message
  with 0,0 to negotiate async when a target suggests a period that is too
  long for us to handle.  Some tape and cdrom drives don't like us doing
  the message reject that we did in the past.

  Fix a problem with handing the QUEUE FULL condition.

  Fix a race condition (most likely the cause of the SCB paging problems) that
  might allow the sequencer to get unpaused before the condition that caused
  it to be paused (a SEQINT) was handled.

  Race condition pointed out by Doug Ledford <dledford@dialnet.net> and
  by "Dan Willis" <dan@plutotech.com>.
