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* Remove some outdated comments.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.

cgd 3a7bbb1acd lip service to making ISA support machine-independent. This is the first
round: moving the drivers into a machine-independent directory.
Some drivers (e.g. fd.c) not moved because they use other pc features (e.g.
CMOS settings), and none of the non-driver files moved, because they're
still pretty much PC specific.  eventually (when other ports with ISA
busses really start using this code), more 'high-level' ISA support will
live here.

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 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.
