thorpej d56c0ff801 Support Adaptec U2W cards with a 64-bit PCI memory range (such cards
are available with Power Macintosh G3 and G4 systems).

thorpej 4656f0ba52 Remove the FreeBSD support from this file. It hasn't worked in FreeBSD
for some time, and only made the code harder to read.

hannken 9d12a71473 Add support for `Adaptec AHA 2940UW Pro'.
Behaves like the `Adaptec AHA 2940UW'.

Device info: product id = 0x8778, Chip = AIC7880P.

bouyer 6f3bab1f59 Merge scsipi branch in the mainline. This add support for ATAPI devices
(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.

thorpej 158a6e52a4 Garbage-collect and uneeded #ifdef. 1997-05-08 04:39:03 +00:00
cgd 36949596f0 rename pci_map_register to pci_mapreg_map. The latter name is more
descriptive, and allows for a sane name for a function which just digs
the info out of the mapping register but doesn't do the mapping.
1997-04-13 20:14:20 +00:00
cgd cf2d73f749 use pci_map_register(). map both mem and I/O spaces, preferring mem
space if it's usable, but falling back to I/O space if mem isn't usable.
1997-04-13 19:48:16 +00:00
cgd db0f072019 clean these up (mostly rename bus_space_{tag,handle}_t variables) so that
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.)

cgd 8aa5282c68 clean up the __BROKEN_INDIRECT_CONFIG chunks of the last change 1997-03-13 01:04:02 +00:00
cgd 4c654c0acf fixes from Matt Jacob so that these can compile and run on the Alpha.
(aic7xxx has been tested and works on the Alpha, bha has not yet been
tested on thne Alpha.)

thorpej 546c8abcee New bus.h implementation/interface:
- No more distinction between i/o-mapped and memory-mapped
	  devices.  It's all "bus space" now, and space tags
	  differentiate the space with finer grain than the
	  bus chipset tag.
	- Add memory barrier methods.
	- Implement space alloc/free methods.
	- Implement region read/write methods (like memcpy to/from
	  bus space).
This interface provides a better abstraction for dealing with
machine-independent chipset drivers.

gibbs b9c06e6fa3 dev/microcode/aic7xxx/aic7xxx.seq,
dev/microcode/aic7xxx_seq.h,
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>.

dev/pci/ahc_pci.c:
  Add support for the 2940AU, an aic7860 based controller.

dev/pci/pcidevs.h, dev/pci/pcidevs_data.h:
  Add product IDs for the 2940AU, aic7860 and aic7855.

  Regen data file.

scsi/scsi_message.h:
  Add MSG_EXT_SDTR_LEN and MSG_EXT_WDTR_LEN - the length of bytes in these
  extended messages.

Thanks to Chuck Cranor <chuck@maria.wustl.edu> for testing these changes
out for me.
