thorpej f60341a382 Store the SCSI version in the scsi_link, and set the LUN in the CDB 
if the version is <= SCSI-2.  This should help some older SCSI
devices that previously needed the "NOLUNS" quirk.  While this is
not strictly necessary on SCSI-2 devices, the spec allows it,
so we set it for SCSI-2 devices "just in case".  See section 7.2.2 of
Draft X3T9.2 Rev 10L for details.

cgd 11ec3588ad (1) add a 'channel' field to scsi_link. 
(2) in scsibusmatch, match channel as appropriate.
(3) add a scsiprint() function, to do the "scsibus at..."
    and channel (if not SCSI_CHANNEL_ONLY_ONE) printing,
    i.e. the common functionality that all SCSI drivers currently
    should be doing.

christos 7e1c82f6f4 - Apply PR/2535: Add support for flex scsi disks. 
- Add a quirk called SCSI_NOMODESENSE for drives like the iomega jaz,
  that don't support mode sense.

mycroft e819063285 Define a full set of [234][bl]tol() and lto[234][bl]() conversion functions, 
inlined.
Use sized types in protocol structures.
Make the definition of scsi_sense_data less ugly.

mycroft 294879d4ee Add SCSI scanner support by Kenneth Stailey and Joachim Koenig-Baltes, 
hacked a bit.  Needs more work.

thorpej 8068d9eeb2 Handle cases like the following: 
- controller calls scsi_done() with error XS_TIMEOUT
	- scsi_done() calls sddone()
	- sddone() calls disk_unbusy()
	- scsi_done() calls controller to retry command (missing the
	  call to disk_busy())
	- controller calls scsi_done()
	- scsi_done() calls sddone()
	- sddone() calls disk_busy(), which panics because of the imbalance.
Bug noticed by Leo Weppleman, who also suggested this fix; pass an additional
boolean argument ("complete") to the device's "done" routine, with a
value of `0' passed from the previous call to "done", and add an additional
call to "done" when the xfer resources are freed.

mycroft 80d7b0695a minphys() functions really should return void. 1995-08-12 20:30:45 +00:00
cgd d8e7ea659c restore a deleted semicolon 1995-07-24 09:03:00 +00:00
cgd 4d0bd10d53 kill structure offest comments in non-fixed-size structures. 
In some of our worlds, pointers just Aren't 4 bytes.
 1995-07-24 07:08:14 +00:00
cgd 3301cf82fd update SCSI minphys routines' definitions to match standard minphys() 
definition and usage.
 1995-07-24 06:55:37 +00:00
cgd f60db5f02a add a SDEV_FORCELUNS flag, as suggested by Jason Thorpe, to force 
the SCSI code to look for LUNs on prehistoric (pre-SCSI 1) drives &
controllers, where normally it would not.

mycroft 1611df6ae0 Update copyrights. 1995-01-26 12:05:49 +00:00
mycroft b76a328caa Redo the `wait for spin up' code. The Mach 3 method clearly doesn't work. 
Also, rearrange the first open sequences a bit; SDEV_OPEN is no longer magic.

mycroft bfd9901daf Fix some oversights in the debugging code. 1994-12-30 05:33:06 +00:00
mycroft 8fd135209c Numerous changes. Many bugs fixed, better autoconfig, a few new features. 1994-12-28 19:42:47 +00:00
mycroft fd32202948 Replace dev_unit with device_softc in scsi_link. Change argument to foostart() 
to void*.

mycroft ef0c18e1cf Always use direct configuration for SCSI devices. 1994-11-03 22:05:08 +00:00
mycroft 54608f7ea0 Remove a couple of i386-specific hacks, and make a couple of others #ifdef 
CONFIG_INDIRECT instead.

cgd 6ac2bbfc35 be more careful with types, also pull in headers where necessary. 1994-10-30 21:43:03 +00:00
mycroft e5d974c51f First cut at making user-level SCSI commands work. This is untested. 
Partly from John Brezak.

cgd fccfa11af5 New RCS ID's, take two. they're more aesthecially pleasant, and use 'NetBSD' 1994-06-29 06:39:25 +00:00

timeout (again).

deraadt a0bcb17e60 support for making dev->id_alive be set, this is for iostat to 
find disk devices. wee bit of a kludge. sub-device attach()
routines must now return 1 for successful attach(), 0 otherwise.
Other bsd's do this too..
 1993-05-04 08:27:29 +00:00
deraadt 2c98ef3b72 new scsi subsystem. 
changes also in config/mkioconf.c
	i386/isa/wd.c, fd.c, and all scsi drivers.
