2006-03-04	All CAM_* values stored in xs->error must be 'interpreted' by	Kenneth R Westerback
	ah[cd]_done() into XS_* values understood by the SCSI code before returning xs to the tender mercies of the SCSI code. So if we bail out without calling ah[cd]_done(), because the request cdb length is excessive, don't use ah[cd]_set_transaction() to put CAM_REQ_INVALID into xs->error, just jam in XS_DRIVER_STUFFUP as ah[cd]_done() would have. If CAM_REQ_INVALID escapes it will be interpreted as XS_SHORT_SENSE as far as I can tell. This code path should never be trod so the net effect should be minimal.
2005-12-28	Strip out fancy timeout code that attempts to mimic FreeBSD's thread	Kenneth R Westerback
	based timeout handling. Use the simple timeout == bus reset model instead. Also move verbose debug output inside #ifdef/#endif. Fixes immediate crashes on encountering a timeout. Noted by per englebrecht when trying 'smartctl -d scsi -a /dev/rsd0c'. Thanks to per englebrecht and luiz gustavo for testing. Should only impact timeout handling. No change to normal processing. ok marco@
2005-11-02	It is invalid to scsi_done(xs) and then return TRY_AGAIN_LATER.	Kenneth R Westerback
	scsi_done() can release the scsi_request xs and TRY_AGAIN_LATER will refer to it and submit it for re-execution. This was being done only if bus_dmamap_load() failed. Ensure the controller resources are freed before returning TRY_AGAIN_LATER, since new resources will be allocated when the command is executed again. Don't bother setting xs->error before returning TRY_AGAIN_LATER as the code returned to sets xs->error to XS_BUSY. ok marco@
2005-10-06	Use correct timer when reinstating timeouts. Adapted from FreeBSD	Kenneth R Westerback
	aic79xx_osm.c r1.22 fix by gibbs.
2004-12-30	Current ahd timeout code does nothing. Add fbsd style timeout	Kenneth R Westerback
	handling which will at least try to recover. ok marco@.
2004-12-28	Don't allow an infinite number of SCSI bus resets per i/o.	Kenneth R Westerback
	ok marco@.
2004-12-27	Fix tag handling for non-U320/packetized devices. Allow tags for these	Kenneth R Westerback
	devices. Tidy up man page, remove lies and cruft. ok marco@.
2004-12-24	Kill bit of ahc cruft. Elminate lots of leading spaces. Other KNF. No	Kenneth R Westerback
	functional change.
2004-12-20	In the rare case that SCSI_RESET is set, ensure that xs->stimeout is	Kenneth R Westerback
	valid and don't call ahd_setup_data() after ahd_execute_scb() may have freed the scb.
2004-12-20	Activate packetized status handling.	Kenneth R Westerback
	ok tdeval@.
2004-12-19	Reduce delta to FreeBSD by adding and using ahd_alloc() rather than	Kenneth R Westerback
	manually reproducing bits in ahd_pci.c. Just as in ahc, avoid allocating and freeing zero length bits of memory for platform data. Don't try to free all or part of ahd_softc, but correctly free allocated memory for seep_config if necessary. Add a final few fields to ahd_softc and scb in preparation for updating/fixing timeout handling. No functional changes.
2004-12-13	Use millisends rather than microseconds in parameters to timer	Kenneth R Westerback
	functions, and ultra-conservative calculations, to avoid possible overflow issues. Also consistant with values passed in scsi requests. Whitespace and comment tweaks. Update FreeBSD tags now that we are sync'd to the latest version. From FreeBSD aic79xx.c r1.33, aic79xx.h r1.23, aic_osm_lib.h r1.4.
2004-11-23	More FreeBSD delta reduction. Use aic_* defines rather than ahd_* one	Kenneth R Westerback
	line and zero line functions. Fix a potential bug (ahd_set_transaction_status was used where ahd_set_scsi_status was intended) inside a currently #ifdef 0/#endif section of code. No functional changes intended except for a bit of extra locking via ahd_list_lock*. ok marco@.
2004-11-18	More NetBSD cruft removal/FreeBSD delta reduction. Whitespace, function and ↵	Kenneth R Westerback
	variable shuffle. No functional change.
2004-11-14	More NetBSD cruft removal, starting with 'struct ahd_pci_busdata' and	Kenneth R Westerback
	the fallout from that. Ensure pcireg_t variables are being used with pci_conf_read/write functions - found one uint16_t variable (pcix_status) being used to store and restore (32 bit) pcireg_t values. Some KNF. No functional changes.
2004-10-10	Work around "overlapped command" issue on devices that are slower than U320. ↵	Marco Peereboom
	Committing this due to a preemptive "I don't like your fix" comment from krw@ Tested by pval@, krw@ and me, ok krw@
2004-08-23	Fix license. ok krw@, deraadt@ tedu@ & Milos Urbanek <urbanek at zoom-int.cz>	Marco Peereboom

2004-08-13	Fix issue with auto request sense handling for both ahc and ahd.	Kenneth R Westerback
	Restore hppa functionality, add sgi functionality for ahc. ok deraadt@, plus marco@, mickey@, pefo@ for various bits.
2004-08-06	Remove __static inline to make the kernel ~24k smaller on i386 and make the ↵	Marco Peereboom
	debug sessions bearable. ok krw@ deraadt@
2004-06-22	Enable ahd interrupts and reset the channel before scanning the bus	Kenneth R Westerback
	for devices. This is how ahc is done too. Fixes probe hang on Theo's box with the 7902B chip. ok marco@
2004-06-21	Fix ahd_[get\|set]_transaction_status vs ahd_[get\|set]_scsi_status confusion.	Kenneth R Westerback
	Allocate max number of SCB's at initialization. Display negotiated transfer parameters. ok marco@
2004-05-25	Attach scsi bus, find devices without crashing, successfully do simple	Kenneth R Westerback
	i/o's on i386. De-static many functions. ok marco@
2004-05-20	Remove bogus $Id.	Marco Peereboom

2004-05-20	Add ahd. ok krw@	Marco Peereboom
