Change 1826 by gibbs@bitkeeper-linux-2.5 on 2003/01/15 10:10:47

	aic79xx.reg:
		Add SEQINT codes for handling task management
		completions.
	
	aic79xx.seq:
		Add notifications to the host of task management
		completions as well as the completions for commands
		that have a task management function pending but
		not yet sent.
	
		Hold a critical section during select-out processing
		until we have a fully identified connection.  This
		removes a race condition with the legacy abort handler.
	
		Correct a few spelling errors in some comments.
	
	aic79xx_core.c
		Flush the good status FIFO in ahd_flush_qoutfifo.
		This routine should now catch all completed commands
		in their various locations and states.
	
		Add support for task management function completions.
	
		If we are a narrow controller, don't set the current
		width to unknown when forcing a future negotiation.
		This just confuses the code into attempting a wide
		negotiation on a narrow bus.
	
	aic79xx_osm.c:
		Enable recovery code.  Behavior should be similar to
		that of the aic7xxx driver for legacy devices.  For
		packetized devices, we will now queue the appropriate
		task management function.
	
		When printing out sense information, format in 16
		byte rows.
	
	scsi_iu.h:
		Add definitions for the task management codes sent
		in SPI4 command information units.

Change 1812 by gibbs@aslan on 2003/01/07 17:38:33

	aic79xx_pci.c:
	aic7xxx_pci.c:
		Disable SERR and pause the controller prior to performing
		our mmapped I/O test.  This should handle the case of
		controllers that do not "auto-access pause".  For legacy
		controllers, use SCB ram instead of scratch ram since
		the latter may contain settings left over from the BIOS
		that we will use if an seeprom is not found.
	
	aic7xxx.h:
	aic7xxx.c:
		Remove the probe_stack code.  The stack is always
		4 deep on legacy controllers, so probing is pointless.
		This also avoids an issue where probing the stack would
		upset the aic7770.
	
	aic7xxx.c:
		Print out the ERROR register in ahc_dump_card_state().
	
	aic7xxx.reg:
		Add a constant for the controller's stack size.
	
	aic7xxx.seq:
		Style nit.  The source is implied to be the destination
		unless overridden in an "and" instruction.

		pre-allocating target devices for initial DV scan.

Change 1807 by gibbs@bitkeeper-linux-2.5 on 2003/01/06 11:58:41

	aic79xx.c:
		Correct ahd_find_syncrate() so that the actual
		syncrate and not the "maximum syncrate" is modified
		by tests that limit syncrate based on PPR options.
	
	aic7xxx.c:
	aic79xx.c:
		Enhance residual diagnostic to indicate if the residual
		if for sense information or normal data transfers.
	
	aic79xx_osm.c:
	aic7xxx_osm.c:
		For the initial DV scan, only instantiate target objects
		for IDs that can exist (i.e. only up to ID 7 on narrow
	
		Record the maximum bus width for fallback in the target
		structure and use this to ensure we never fallback to
		wide on a narrow target.
		channels).
	
		Add DV diagnostic for failed inquiry verification.
	
	aic79xx_osm.h:
	aic7xxx_osm.h:
		Add dv_max_width to target structures and shrink several
		fields to 8bits.

Change 1805 by scottl@scottl-junior-freebsd on 2002/12/30 21:13:11

	Convert the use of MAXBSIZE in the dma tag to more appropriate values.
	Use BUS_SPACE_MAXSIZE_32BIT for the parent dma tags, and
	(NSEGS - 1) * PAGE_SIZE for the data buffer tags.  FreeBSD/sparc64 is
	more strick about checking these values that other arches.

	aic79xx_osm.c:
	aic7xxx_osm.c:
		Reorganize DV state machine so that full inquiry data
		is retrieved prior to testing to see if the unit is ready.
		We now use this full inquiry data to assume defaults if
		for some reason the DV state machine fails to configure
		the device.  This failsafe mechanism should ensure that
		these devices are at least configured in the same fashion
		as they were before the addition of DV to these drivers.
	
	aic79xx_osm.h:
	aic7xxx_osm.h:
		Re-arrange DV state enum to reflect current state machine
		transitions.
	
		Add additional target flags used to implement the DV
		failsafe mechanism.

	aic79xx_osm.c:
	aic7xxx_osm.c:
		Use down_interruptable() rather than down() to avoid
		having our thread counted toward the load average.
		We disable all signal sources to that the down_interruptable()
		is not really interruptable().  Singals are not required for
		the drivers to terminate the DV threads on unload.
