Change 1849 by gibbs@bitkeeper-linux-2.4 on 2003/01/20 16:23:35

	aic79xx_osm.c:
		Correct the BUILD_SCSIID macro to take into account the
		future removal of target, lun and channel from the
		scsi_cmnd structure.
	
		Clean up ahd_linux_initialize_scsi_bus().  The indirection
		was left over from the port from aic7xxx where twin
		channel adapters come into play.  The result in the aic79xx
		driver just looked silly.

Change 1848 by gibbs@bitkeeper-linux-2.4 on 2003/01/20 16:20:47

	aic79xx.c:
		Fix a missed goal.period -> goal.offset change.  In
		this case, the bug resulted in comparing a period
		against an offset.

Change 1847 by gibbs@bitkeeper-linux-2.4 on 2003/01/20 10:14:37

	aic79xx.c:
	aic7xxx.c:
		Indicate the features, bugs, and flags set in the softc
		that are used to control firmware patch download when
		booting verbose.
	
	aic7xxx.c:
		Fix an ifdef bug that caused sequencer debugging to
		be enabled always.
	
		Clear the ultraenb flag in our tstate during startup.
		The ultraenbled'ness of a device is recorded in the user
		transfer settings.  tstate->ultraenb bitmask indicates
		which devices we have negotiated an ultra speed with.
		Just after initialization, we are async.  Setting the
		ultraenb flag while async seems to be harmless, but it
		was confusing to see the ULTRAENB flag set in the SCB.
	
		Allow ahc_dump_card_state() to be called when the sequencer
		is not paused.  Add dump card state markers as in the U320
		driver.

	aic7xxx.c:
	aic7xxx.h:
	aic7xxx_pci.c:
		Take another stab at disabling PCI errors in the aic7xxx
		driver.  We now just clear the PERRRESEN bit in the command
		register.  This option is now enabled via a new flag in
		ahc->flags: AHC_DISABLE_PCI_PERR.
	
	aic7xxx_osm.c:
		Hook the already existing pci_parity option.  Parity
		defaults to off since so many Linux users have clunky
		VIA chipsets that cause spurious warnings.

	aic79xx_osm.c:
	aic79xx_osm.h:
	aic7xxx_osm.c:
	aic7xxx_osm.h:
		Adapt to upcoming 2.5.X change.  The host, target, channel,
		and lun fields are disappearing from the scsi_cmnd structure.
		We must instead get this data from the scsi_device structure
		hung off the command.  The only trick in this is an update
		to how we fake up DV commands.  We now need to fake up a
		scsi_device too.

Change 1836 by gibbs@bitkeeper-linux-2.4 on 2003/01/16 14:39:58

	aic79xx.c:
		Only send an async update to the luns affected by
		the device reset now that ahd_handle_devreset is
		called for lun resets too.
	
	aic79xx_osm.c:
		Only bother dumping card state after we've determined
		that the command to be aborted is still active on the
		controller.
	
	aic79xx_osm.c:
	aic7xxx_osm.c:
		Have the AC_SENT_BDR handler manually set the was_reset
		and expecting_cc_ua flags in all devices that are
		affected by the target/lun reset.
	
		Never allow cmd->retries to go below zero.  cmd->retries
		is not incremented when a command goes through recovery.
		This could allow the retry count to suddenly become a
		very large number.

Change 1834 by gibbs@aslan on 2003/01/15 21:32:22

	aic7xxx.seq:
		Correct a target mode regression that prevented the
		driver from properly handling unexpected
		messages (negotiation, etc).

Change 1833 by gibbs@bitkeeper-linux-2.4 on 2003/01/15 21:27:13

	aic79xx_osm.c:
		Split out the abort handler from the dev reset handler.
		The dev reset handler will now use a new SCB to issue
		the dev reset.  This avoids a potential problem with
		SCB race issues for dev resets.
	
		Manually set the task management function now that
		ahd_queue_scb() doesn't do this for us.

Change 1832 by gibbs@bitkeeper-linux-2.4 on 2003/01/15 21:20:59

	aic79xx.c:
		Update copyright for 2003.
	
		Modify ahd_handle_devreset so that it can handle
		lun resets in addition to target resets.
	
		Correct a bug in the illegal phase handler that
		caused us to drop down to narrow when handling the
		unexpected command phase case after 3rd party
		reset of a packetized device.
	
		Add some diagnostics to the task management function code.
	
		Use ahd_handle_devreset for lun and target reset task
		management functions.
	
		Handle the abort task TMF race case better.  We now
		wait until any current selections are over and then
		set the TMF back to zero.  This should cause the sequencer
		to ignore the abort TMF completion should it occur.
	
		Correct a regression in ahd_sent_msg that caused it to fail
		to recognize any 1byte messages other than identify.
	
	aic79xx_inline.h:
		Allow callers to ahd_send_scb() to set the task management
		function.

Change 1827 by gibbs@bitkeeper-linux-2.5 on 2003/01/15 10:18:44

	aic7xxx.h:
		Reformat a few comments to follow driver style.
	
		Add a controller flag that indicates that a controller
		has not been initialized by the BIOS.
	
	aic7xxx.c:
		Disable PCI error interrupts on PCI adapters prior
		to the Ultra2 controllers.  This brings us in line
		with what the other Adaptec drivers do, but it is
		still not clear exactly why this status reporting
		might be broken.
	
		Don't set our width to unknown when forcing negotiation
		on narrow controllers.  This will confuse the negotiation
		code into negotiating with a wide message on narrow
		controllers.
	
		In ahc_reset(), record whether or not we found the
		controller in a reset state.  If the controller was
		already reset, assume that no BIOS has initialized
		the controller and ignore left over scratch ram
		settings.
	
		In ahc_dump_card_state() fix a logic reversal.  The
		SCSIPHASE register only exists on U160 controllers.
		The SCSISIGI register exists on all controllers.  Not
		the other way around.
	
	aic7xxx_osm.c:
		Format sense diagnostic in 16 byte rows.
	
		Remove a superfluous diagnostic printf.
	
	aic7xxx_pci.c:
		Ensure that the PCIERRGENDIS bit is set in the
		PCIERRGEN config space register.  Perhaps this
		is a reason for the spurios parity errors reported
		on U160 controllers.
