mycroft 0349c5b9e0 Add a multiplexer for BOCA serial boards. 1995-01-03 22:26:36 +00:00
hpeyerl 09834a5bd3 This is correct according to the docs on both cards.
Doesn't seem to make any difference to the known problems though.

mycroft 3e4a358e28 Patch from Thomas Eberhardt to make PCnet-32 chips work. 1994-12-12 04:39:52 +00:00
christos 303841c92e 3c509 fixes to avoid adapter getting stuck in high traffic conditions.
I don't particularly like the fixes, but at least now the 3c509 never
gets stuck. On the other hand, performance still sucks in some cases.
1994-12-10 14:52:02 +00:00

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 21e911d911 Update for new autoconfig. 1994-11-07 09:03:48 +00:00
mycroft d5f99262a9 Since npxdna() and npxsave() are only ever called at spl0 now, we can get rid
of all the overhead of frobbing the IDT, and just use a simple flag to tell
npxintr() to ignore interrupts.  This allows lots of code reduction.
Also, update some comments and add some DIAGNOSTIC code to detect is these
assumptions ever become wrong.
