ahc_eisa.c:

Browse Source 
ahc_pci.c:
	Prepare for making ahc a module by adding module dependency
	and version info.

aic7770.c:
	Remove linux header ifdefs.  The headers are handled differently
	in Linux where local includes (those using "'s instead of <>'s)
	are allowed.

	Don't map our interrupt until after we are fully setup to
	handle interrupts.  Our interrupt line may be shared so
	an interrupt could occur at any time.

aic7xxx.c:
	Remove linux header ifdefs.

	current->curr to avoid Linux's use of current as a
	#define for the current task on some architectures.

	Add a helper function, ahc_assert_atn(), for use in
	message phases we handle manually.  This hides the fact
	that U160 chips with the expected phase matching disabled
	need to have SCSISIGO updated differently.

	if (ahc_check_residual(scb) != 0)
		ahc_calc_residual(scb);
	else
		ahc_set_residual(scb, 0);

       	becomes:

	ahc_update_residual(scb);

	Modify scsi parity error (or CRC error) handling to
	reflect expected phase being disabled on U160 chips.

	Move SELTO handling above BUSFREE handling so we can
	use the new busfree interrupt behavior on U160 chips.

	In ahc_build_transfer_msg() filter the period and ppr_options
	prior to deciding whether a PPR message is required.
	ppr_options may be forced to zero which will effect our
	decision.

	Correct a long standing but latent bug in ahc_find_syncrate().
	We could choose a DT only rate even though DT transfers were
	disabled.  In the CAM environment this was unlikely as CAM
	filters our rate to a non-DT value if the device does not
	support such rates.

	When displaing controller characteristics, include the
	speed of the chip.  This way we can modify the transfer
	speed based on optional features that are enabled/disabled
	in a particular application.

	Add support for switching from fully blown tagged queing
	to just using simple queue tags should the device reject
	an ordered tag.

	Remove per-target "current" disconnect and tag queuing
	enable flags.  These should be per-device and are not
	referenced internally be the driver, so we let the OSM
	track this state if it needs to.

	Use SCSI-3 message terminology.

aic7xxx.h:
	The real 7850 does not support Ultra modes, but there are
	several cards that use the generic 7850 PCI ID even though
	they are using an Ultra capable chip (7859/7860).  We start
	out with the AHC_ULTRA feature set and then check the
	DEVSTATUS register to determine if the capability is really
	present.

	current -> curr

	ahc_calc_residual() is no longer static allowing it to
	be called from ahc_update_residual() in aic7xxx_inline.h.

	Update some serial eeprom definitions for the latest
	BIOS versions.

aic7xxx.reg:
	Add a combined DATA_PHASE mask to the SCSIPHASE register
	definition to simplify some sequencer code.

aic7xxx.seq:
	Take advantage of some performance features available only
	on the U160 chips.  The auto-ack feature allows us to ack
	data-in phases up to the data-fifo size while the sequencer
	is still setting up the DMA engine.  This greatly reduces
	read transfer latency and simplifies testing for transfer
	complete (check SCSIEN only).  We also disable the expected
	phase feature, and enable the new bus free interrupt behavior,
	to avoid a few instructions.

	Re-arrange the Ultra2+ data phase handling to allow us to
	do more work in parallel with the data fifo flushing on a
	read.

	On an SDTR, ack the message immediately so the target can
	prepare the next phase or message byte in parallel with
	our work to honor the message.

aic7xxx_93cx6.c:
	Remove linux header ifdefs.

aic7xxx_freebsd.c:
	current -> curr

	Add a module event handler.

	Handle tag downgrades in our ahc_send_async() handler.
	We won't be able to downgrade to "basic queuing" until
	CAM is made aware of this queuing type.

aic7xxx_freebsd.h:
	Include cleanups.

	Define offsetof if required.

	Correct a few comments.

	Update prototype of ahc_send_async().

aic7xxx_inline.h:
	Implement ahc_update_residual().

aic7xxx_pci.c:
	Remove linux header ifdefs.

	Correct a few product strings.

	Enable several U160 performance enhancing features.

	Modify Ultra capability determination so we will enable
	Ultra speeds on devices with a 7850 PCI id that happen
	to really be a 7859 or 7860.

	Don't map our interrupt until after we are fully setup to
	handle interrupts.  Our interrupt line may be shared so
	an interrupt could occur at any time.
