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* Remove some outdated comments.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 87d587e640 Simplify some sanity checks. 1995-01-13 14:46:44 +00:00
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 639a64de08 Fix a null pointer reference. 1994-11-29 21:35:13 +00:00
mycroft 51bed8d804 Add an assertion mechanism to check for more abnormal conditions. 1994-11-29 21:29:56 +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.

mycroft 29414c5a0a Change all of the uses of IRQ{0-15} and bit masks to use plain numbers
rather than bit shifting.

cgd a0a7429482 lots of changes: prototype migration, move lots of variables, definitions,
and structure elements around.  kill some unnecessary type and macro
definitions.  standardize clock handling.  More changes than you'd want.
