thorpej 5f0577babc Adapt to the new scsipi_adapter interface. 1998-11-19 21:43:00 +00:00
thorpej 29d472f53d Garbage-collect the open_target_lu and close_target_lu entry points from
struct scsipi_adapter; they were not used.

Add a scsipi_ioctl entry point to struct scsipi_adapter.  This will be
used to issue ioctl commands to the host adapters.

Inspired by PR #6090, from Matt Jacob.

eeh a2dd74ed79 Merge paddr_t changes into the main branch. 1998-08-13 02:10:37 +00:00
leo d3febbb5aa Do endian swaps where appropriate. This is currently dependent on 'BYTE_ORDER'
since the driver only supports little endian busses.

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 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
is unchanged.

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.)

thorpej 7d4d4753a8 Implement a simple scsi xfer queue to avoid presenting a resource
shortage to the upper scsi layers, which don't (yet) deal well with
resource shortages.

thorpej 16c4c5af26 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.

thorpej c4366945e5 Quiet the ahc driver down a bit by only enabling some of less useful
messages #if defined(DEBUG) in the NetBSD case.

cgd 71ad30d0e9 (1) set scsi_link channel to either the appropriate channel (if a
multi-channel driver), or to SCSI_CHANNEL_ONLY_ONE if a
    single-channel driver.
(2) use scsiprint() rather than a locally-defined autoconfig print
    function, and kill any locally-defined print function.
1996-08-28 18:59:15 +00:00
cgd 2a73ef60b7 change cfprint_t type definition to take a const char *, rather than
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).
