mark mulaw as emulated (it's done via a mapping table)
use GUS query encoding routine, even on GUS max, since the encoding
stuff is handled by the GF1.
XXX might not be right for recording, but it's correct for playback.
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.

- Determine and remember if we are a floppy.
- Workaround for what is apparently a firmware bug - ignore the sector
size returned by the device. On my Firepower's floppy, block-size
is the same as max-transfer, which causes Lossage.
- Don't read the disklabel on a floppy; do what the ISA floppy driver
does, which is assign the entire disk to each "partition", although
we do not deal with the density stuff.

this code makes equal sense for memory and I/O space, prefer to map

This can be disabled (to save a bit of space) with the NO_KERNEL_RCSIDS

In ELF-format kernels, these strings are present in the kernel binary but

to keep them from being loaded, so they _are_ loaded into memory.)

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).

is called *after* the driver `done' routine. This fixes disk I/O statistics
on SCSI devices.
Also, calling the `done' routine with a `complete' argument of 0 and actually
having it do anything meaningful loses in at least 3 ways, so just nuke the
argument altogether and don't call it this way. If the driver needs to do
some error handling, that's what `err_handler' is for.

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.

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.
(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.

- Keep a freelist of component buffer headers, defaulting
to 8 headers per component (tunable with the CCDNBUF
kernel compile option).
- When allocating a component buffer, try to pull a header
off the freelist first, falling back on MALLOC() if the
freelist is empty. Use MALLOC() rather than malloc(),
because it will attempt to short-cut the allocation before
actually making a full-blown malloc() call.
- Keep statistics on how many component buffer headers have
been allocated and how many of those allocations have
resulted in freelist misses.
With these changes, I observed measurable decreases in system and
wall clock time on operations on an 8G ccd, as well as a measurable
drop in the time spent in ccdbuffer() (measured with kernel profiling).

Tested on alpha by cgd, tested on several i386 boxes. Certainly causes
no harm to the goddamned mess, but the NCR driver only works when you
perform voodoo rituals on it anyway.
This is what Dave said (in email) has been added to the driver:
----------------------------------------------------------------------
This seems to be the most significant change:
General cleanup and new features for 53c875 based cards, especially the
Tekram DC390W/U/F, whose config EEPROM can now be dumped, if the kernel
is built with option NCR_TEKRAM_EEPROM.
Other changes:
- add brackets to expansion of OUTB/W/L macro arguments.
- remove unused NCB structure element ns_async
- support sync. SCSI offset of 16 (instead of only 8) on 825A and 875
- correctly identify 53c810A and 53c825A chips
- preserve SCSI BIOS settings of PCI performance options
- remove (already disabled) support for NCR reset because of command timeout
- reverse order of reading of SCSI and DMA specific interrupt cause registers
- add definition of Tekram config EEPROM contents (not currently used)

comments in pr port-i386/2358: "if_ep/3C590 no longer working"
* Only call Vortex media-config code on PCI-attached devices, until
we know if it works on ISA and EISA large-packet devices also.
* Fix typo in printf of MAC address
rather than unknown.
* Look for 100mbit interfaces, and for any present, set corresponding
bits in `conn' argument to epconfig(). epconfig() will now print
100Mbit media by name.
look for 100mbit Xcvrs, print their names, add to ep_connectors.
* Print 10baseT as 10baseT, since media name (utp) is no longer a unique
transceiver type.
* Redo FIFO memory size printing, also show Tx/Rx split (xxx isa 3c509?).
* Print MAC address on a separate line, with 100Mbit media and fifo-ram
info it no longer fits on the same line as media types.
* Comment the fact that the "connection" media-selection code just doesn't
grok 100Mbit media.
* add code to look for 3c59x/3c90x media-select and autoconfig bits, though
we don't yet dynamically probe media when the autoconfig bit is set
(see previous bullet).
* XXX the whole connector/media code should be redone, perhaps a' la
the BSDI ifmedia design.
For now, we really only need 8 bits of media type.
* Add bogus definitions for 100mbit transcievers, to be set in the
"conn" argument to ep_config(). Should really use the same bits
as in EP_W0_CONFIG_CTRL bits, but I don't know what bits the 3c515
&c use for 100mbit media.
* Define bitflags for 100Mbit transceiver options in ep_connectors.
* Add definitions of powerup/powerdown commands. for interfaces with
power management. Should send a powerup after APM resume?
* Add definition of fragment-busmaster (vortex) START_DMA command.
* Add definition of PCI configuration-space media-present bits.
(really just EP_W3_RESET_OPTIONS remapped into pci config space.)
* Add comments describing what the #define's above are used for.
