Change History (most recent first):
|
|
|
|
<ML2> 1/5/94 pdw Added SCSIBusy to OldSCSICalls even though it's not used in
|
|
XPTOldCall.c.
|
|
<SMG2> 9/29/93 chp Include ACAM.h if necessary.
|
|
<SM12> 10/14/93 pdw <MC> roll-in.
|
|
<MC2> 10/12/93 pdw Added support for Synchronous data transfers, rewrote State
|
|
Machine, message handling etc.
|
|
<SM11> 6/29/93 pdw Massive checkins: Change asynchronicity mechanism to CallMachine
|
|
stack switching mechanism. Adding support for Cold Fusion.
|
|
Rearranging HW/SW Init code. Some code optimizations.
|
|
<SM10> 5/5/93 PW Converted names to meanies-friendly names. Updated with latest
|
|
from Ludwig stuff.
|
|
<LW4> 3/26/93 PW Changing the name of CallCompRoutine to XPTCallCompRoutine as
|
|
part of moving all EnteringSIM/ExitingSIM calls into SIM.
|
|
<LW3> 3/1/93 DCB Changed prototype to CallCompRoutine to make life easier for
|
|
developers.
|
|
<LW2> 1/27/93 PW Removed DItoLUN/Target macros and moved some prototypes to
|
|
XPTpriv.h
|
|
<SM6> 12/5/92 PW Added kSCSICmdInProgress state for support of returning from
|
|
SCSICmd before REQ for next phase.
|
|
<SM5> 11/20/92 PW Removed DItoBus macro and added InitXPT prototype.
|
|
<SM4> 11/1/92 DCB Changed final status to OSErr so that CallCompRoutine won't
|
|
truncate the result.
|
|
<SM3> 10/30/92 DCB Changes to reflect new ACAM.h
|
|
<SM2> 10/8/92 PW Added globals needed for variable-sized SCSI_IO support.
