christos 86373f8cf9 backout kprintf changes 1996-10-13 01:37:04 +00:00
christos 58953408cb printf -> kprintf, sprintf -> ksprintf 1996-10-10 22:04:48 +00:00
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).

mycroft a8e5b5ba47 Remove some unneeded FIFO flushes and reorder some register changes per the
6360 manual.  Turn off synchronous negotiation.

mycroft 9c6e05d835 Minor optimization, and do a CLRCH after (re)selection just to be safe. 1996-04-03 15:58:13 +00:00
mycroft b82447e3e1 * Change message priorities so that ABORT comes after IDENTIFY.
* Add an ACB_RESET flag, so that a BUS DEVICE RESET can be queued within the
driver.
* If ACB_ABORT or ACB_RESET is set during reselection, schedule a message and
assert ATN.
* Optimize aic_datain_pio(), aic_dataout_pio() and aicintr() somewhat.
* Schedule a timeout only when we select the target, so that commands can't
time out prematurely.

mycroft d0742ed3c5 Several things:
1) If we get an unexpected disconnect, issue a REQUEST SENSE, as recommended
by the SCSI-2 spec.  If the target created a contingent allegiance condition,
this will clear it.  Also, if it happened while sending a SDTR or WDTR message,
disable negotiation for that target.
2) Since some lame devices still don't deal correctly, make sure we deassert
ATN if our last message out is interrupted.  If we get a MESSAGE PARITY ERROR,
we'll reassert ATN anyway.  This should ensure that we never have to send a
MESSAGE NO OPERATION.
3) Set AIC_ABORTING only when actually sending a BUS DEVICE RESET or ABORT,
so we get better error detection.
4) Other internal reorganization of no consequence.

mycroft 778f21db6a Use `{in.out}b(iobase + ...' rather than including the base address in
the register definitions.

thorpej 6d9ea4cf59 New device attachment scheme:
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.

mycroft 3da4b2a160 The IST_* and IPL_* constants are not bus-specific; don't treat them as such.
Change splimp -> splnet in Ethernet, ARCnet, and FDDI drivers.

mycroft 80d7b0695a minphys() functions really should return void. 1995-08-12 20:30:45 +00:00
cgd 830a91b2e9 update SCSI minphys routines' definitions to match standard minphys()
definition and usage.
1995-07-24 07:16:44 +00:00
cgd 8a640328ed clean up several ISA device interfaces: autoconfiguration, header
inclusion, and interrupt configuration.  more work still needs to be done,
but it's getting better...
1995-04-17 12:06:30 +00:00
mycroft e9c2b98c11 Comment a potential bit of lossage. 1995-02-02 21:08:42 +00:00
mycroft 8abb91e18d Various:
* Make synchronous negotiation work.
* Use the bitbucket when the target requests too much data.
* Loop in aicintr() until we get to a state where we have to wait.
1995-02-01 21:49:37 +00:00
mycroft ab5662014f Correct some more of the synchronous stuff, and omit it completely if
AIC_USE_SYNCHRONOUS is 0.
1995-02-01 16:56:42 +00:00
mycroft 4653b28a42 Various:
* Always enable disconnection.
* Add some more per-controller variables: initiator ID, clock frequency,
min and max sync period.
* Correct sync period calculations.
* Remove sc_progress.
* Move most of the reselection handling into a separate function.
* Remove some outdated comments.
* Remove message bytes from FIFO even when dropping them on the floor.
* Some cosmetic cleanup.

mycroft 37e16c5747 Don't print line numbers in most of the diagnostics. 1995-01-07 06:49:35 +00:00
mycroft 7f61bec5cd Cosmetic changes, to look more like the new esp.c will. 1995-01-07 01:51:07 +00:00
mycroft b5cf1b5ddd Add interrupt sharing types. 1995-01-03 01:30:14 +00:00
mycroft 76b0b02cc3 Fix non-serious typo. 1994-12-31 05:34:00 +00:00
mycroft 8fd135209c Numerous changes. Many bugs fixed, better autoconfig, a few new features. 1994-12-28 19:42:47 +00:00
mycroft 5584ff927f Don't stall the queue on CHECK SENSE if we get a reselect while selecting. 1994-11-30 02:08:01 +00:00

mycroft 58cb5339d6 For consistency... 1994-11-29 20:57:28 +00:00
mycroft 41b26a6dfd Handle BUS FREE phase a little differently, to get better error detection. Other
cleanup.
1994-11-29 20:08:27 +00:00
mycroft bb90feebac Disable debugging breakpoints by default. 1994-11-29 17:56:49 +00:00
mycroft 5ac2484d95 * Redo most of the message and phase state machines. Multiple pending
message outs should now work correctly (including retransmissions).
Multiple messages ins should be more efficient.  Missing REQ after
reselection phase should now (correctly) cause a wait with ENREQINIT
set.

* Abstract out the reselection out sequence, and use it directly to
get sense info.  (This is somewhat faster than the generic done/sched
sequence.)

* If there are no ACBs available, wait interruptibly for one.

* Leave the interrupt registers alone during message in/out; just
watch for phase change.  Don't (incorrectly) reenable interrupts
during data in/out; defer that to aicintr().

* Handle command pointer per SCSI 2 spec.

* Other minor coding improvements.
