2010-03-23Change the scsi_cmd function member of scsi_adapter from int toKenneth R Westerback
void. Use XS_NO_CCB error in the scsi command (xs) to report the NO_CCB condition. Eliminates all SUCCESSFULLY_QUEUED and COMPLETE confusion and untangles the midlayer from the adapter a bit more. Eyes and some fixes by miod@ There may be some compile issues on little used (i.e. I don't have any) drivers but the change is mechanical and thus easy to remedy. ok dlg@
2010-01-10A couple of missed ITSDONE setting before scsi_done().Kenneth R Westerback
seagate/trm/aha1742 were the only drivers paranoid enough to check ITSDONE on getting the xs to execute. And optimistic enough to think simply restting the flag would be a good thing. Have them chill out like everyone else, reducing ITSDONE noise some more.
2010-01-10Set ITSDONE in scsi_done() and zap trivial instances of setting itKenneth R Westerback
in the drivers just before calling scsi_done(). ok dlg@ beck@
2009-11-22Bring last drivers fully into the NO_CCB world by replacingKenneth R Westerback
TRY_AGAIN_LATER uses with equivalent NO_CCB. Eliminates confusion between the two as was always intended. buf I/O's that can't be started get pushed back onto the front of the queue and retried. Others get sent back to originator as failures. No more epi-cycle looping inside the SCSI midlayer hoping the problem goes away. Various testers, no objection from miod@ as vs(4) was tested by nick@.

2009-02-16Extend the scsi_adapter minphys() callback to take a struct scsi_link *Miod Vallat
as additional argument. This will allow intermediate layers between scsi devices such as sd and scsi host adapters to take appropriate action if necessary.

2008-06-26First pass at removing clauses 3 and 4 from NetBSD licenses.Ray Lai
Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors. OK deraadt@

2005-12-03The first thing done when XXX_scsi_cmd() returns TRY_AGAIN_LATER isKenneth R Westerback
to set xs->error to XS_BUSY. So it is pointless and misleading to set xs->error to XS_TIMEOUT, XS_DRIVER_STUFFUP or XS_BUSY just before returning TRY_AGAIN_LATER. No functional change.

2003-12-24Sync ahc with NetBSD, which was in turn updated from FreeBSD by PascalKenneth R Westerback
Renauld of Network Storage Solutions, Inc. Many fixes, wider device support. In particular, the notorious 'Target 0' problem seems to be fixed. Does *not* include any updates to isa or eisa code beyond what was necessary to compile. Known issues: 1) Tagged Queuing is probably not optimal. 2) PPR negotiation may not be fully functional. 3) No support yet for freezing devices or channels. 4) The mechanism for preventing 'A' and 'B' channel confusion during probe can fail if scsibus > 254 found. 5) Requeuing I/O's not working. A workaround will be committed almost immediately. At the moment timeouts, SCSI message rejects, aborting SCB's and trying to freeze a device may cause incomplete i/o's to be reported as complete. 6) Verbosity and probe messages need work. 7) Last disk on bus seems to go through an extra re-negotiation. 8) >16 devices on an adapter will trigger the usual problems of total openings exceeding available SCB's under heavy load. Tested by deraadt@, beck@, miod@, naddy@, drahn@, marc@ amoung others. ok deraadt@.
