aic7xxx.c:

Browse Source 
aic7xxx.h:
	Split out core chip initialization into ahc_chip_init().
	This will allow us to reset the chip correctly at times
	other than initial chip setup.

aic7770.c
aic7xxx_pci.c:
	Flesh out bus chip init methods for our two
	bus attachments and use these, in addition to
	bus suspend/resume hooks to get the core in
	better shape for handling these events.

	When disabling PCI parity error checking, use FAILDIS.
	Although the chip docs indicate that clearing PERRESPEN
	should also work, it does not.

	Auto-disable pci parity error checking after informing
	the user of AHC_PCI_TARGET_PERR_THRESH number of parity
	errors observed as a target.

aic7xxx.h:
aic7xxx_pci.c
aic7770.c
aic7xxx.c
	Add the instruction_ram_size softc field.

	Remove the now unused stack_size softc field.

	Modify ahc_loadseq to return a failure code
	and to actually check the downloaded instruction
	count against the limit set in our softc.

	Modify callers of ahc_loadseq to handle load
	failures as appropriate.

	Set instruction RAM sizes for each chip type.

aic7xxx_pci.c:
	Add some delay in the aic785X termination
	control code.  This may fix problems with
	the 2930.

	Be consistent in how we access config space
	registers.  16bit registers are accessed using
	16bit ops.

aic7xxx.c:
	Correct spelling errors.

	Have ahc_force_renegotiation() take a devinfo as is done
	in the U320 driver.  Use this argument to correct a bug
	in the selection timeout handler where we forced a renegotiation
	with the last device that had set SAVED_SCSIID.  SAVED_SCSIID
	is only updated once a selection is *sucessfull* and so is
	stale for any selection timeout.

	Cleanup the setup of the devinfo for busfree events.  We
	now use this devinfo for a call to ahc_force_renegotiation()
	at the bottom of the routine, so it must be initialized in
	all cases.

	In ahc_pause_and_flushwork(), adjust the loop so that it
	will exit in the hot-eject case even if the INT_PEND mask
	is something other than 0xFF (as it is in this driver).

	Correct a wrapping string constant.

	Call ahc_fini_scbdata() after shutdown so that
	any ahc_chip_init() routine that might access
	SCB data will not access free'd memory.

	Correctly setup our buffer tag to indicate that 39bit
	addressing is available if in 39bit addressing mode.

	Rearrange some variable declarations based on
	type size.

aic7xxx.c
aic7xxx.h:
aic7xxx.reg:
	Consistently use MAX_OFFSET for the user max syncrate
	set from non-volatile storage.  This ensures that the
	offset does not conflict with AHC_OFFSET_UNKNOWN.

	Change AHC_OFFSET_UNKNOWN to 0xFF.  This is
	a value that the curr->offset can never be,
	unlike '0' which we previously used.  This
	fixes code that only checks for a non-zero
	offset to determine if a sync negotiation
	is required since it will fire in the unknown
	case even if the goal is async.

	Change MAX_OFFSET to 0x7f which is the max
	offset U160 aic7xxx controllers can negotiate.
	This ensures that curr->offset will not
	match AHC_OFFSET_UNKNOWN.

aic7xxx_inline.h:
	Have our inline interrupt handler return with a value
	indicating whether we serviced a real interrupt.  This
	is required for Linux support.

	Return earlier if the interrupt is not for us.
