128aa5a022 Hack around a bug in the 2200 and 2120 controllers that connot DMA
commands from below the first 8K of physical memory.  A better fix
is to modify the busdma api to allow either inclusion ranges or
multiple exclusion ranges, but that debate is for another day.

aaa160f357 bus_dmamap_sync() overhaul:
- Remove NetBSD-style or-ed together BUS_DMASYNC operations, in some
  cases relaxing the (intended) syncing operation a bit.
- Add syncs before reading the descriptor rings.
- Try to combine syncs where possible to avoid overhead.
- Sync all maps before unloading them.

- Remove NetBSD-style or-ed together BUS_DMASYNC operations, in some
  cases relaxing the (intended) syncing operation a bit.
- Stop pretending that that we can sync part of a dmamap: replace the
  GEM_CDTXSYNC and GEM_CDRXSYNC macros with GEM_CDSYNC to sync the

  the overhead.
- Sync all maps before unloading them.
- Remove a few syncs which should be unnecessary.

70b41139c3 aic7xxx.reg:
Add a constant for the controller's stack size and the
	maximum scsi offset.

aic7xxx.seq:
	Style nit.  The source is implied to be the destination
	unless overridden in an "and" instruction.

	Update target mode code for changes in identify seen
	sequencer flags.

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.

	Honor the AHC_NO_BIOS_INIT flag.

	Allow PCI interrupt reporting to be disabled,
	by clearing the PERRRESEN bit in the command
	register.  This option is now enabled via a new
	softc flag: AHC_DISABLE_PCI_PERR.

	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.

	Make use of new ahc_inl/outl() inlines.

aic7xxx.h:
	Reformat a few comments to follow driver style.

	Add a controller flags that indicate that a controller
	has not been initialized by the BIOS and whether to
	disable PCI parity errors..

	Remove stack probing softc members.

	Add a few more syncrate constants that are useful in speed
	fallback calculations.

	Add the SHOW_MASKED_ERRORS debug flag.

aic7xxx.h:
aic7xxx.c:
	Implement the SCB_SILENT flag.  This is useful for
	hushing up the driver during DV or other operations
	that we expect to cause transmission errors.  The
	messages will still print if the SHOW_MASKED_ERRORS
	debug option is enabled.

aic7xxx_inline.h:
	Implement ahc_[in|out][w|l|q].  This removes the need
	for manual 'or and shift" type operations throughout
	the driver.

aic7xxx.c:
	Move SELTO dignostic so that the SCB is still valid
	when we use it for printing path information.

	If we are narrow, limit syncrate to Ultra2.

	Don't clobber ppr_options when forcing a renegotiation.
	The current ppr_options may be referenced while queuing
	new commands.  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.

	Add an "asserting atn" diagnostic with controller/target
	information.

	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.

	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.

	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.

	Enhance residual diagnostic to indicate if the residual
	if for sense information or normal data transfers.

	Indicate the features, bugs, and flags set in the softc
	that are used to control firmware patch download when
	booting verbose.

	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.  Also print out the ERROR register.

	Allow ahc_dump_card_state() to be called when the sequencer
	is not paused.  Add dump card state markers as in the U320
	driver.

0794987d01 aic79xx.c:
Implement the SCB_SILENT flag.  This is useful for
	hushing up the driver during DV or other operations
	that we expect to cause transmission errors.  The
	messages will still print if the SHOW_MASKED_ERRORS
	debug option is enabled.

	Save and restore the NEGOADDR address when setting
	new transfer settings.  The sequencer performs lookups
	in the negotiation table too and it expects NEGOADDR
	to remain consistent across pause/unpause sessions.

	Consistently use "offset" instead of "period" to determine
	if we are running sync or not.

	Add a SHOW_MESSAGES diagnostic for when we assert ATN
	during message processing.

	Print out IU, QAS, and RTI features when showing transfer options.

	Limit the syncrate after all option conformance
	changes have taken place in ahd_devlimited_syncrate.
	Changes in options may change the final syncrate we
	accept.

	Keep a copy of the hs_mailbox in our softc so that
	we can perform read/modify/write operations on the
	hs_mailbox without having to pause the sequencer to
	read the last written value.  Use the ENINT_COALESS
	flag in the hs_mailbox to toggle interrupt coalessing.

	Add entrypoints for enabling interrupt coalessing and
	setting both a timeout (how long to wait for commands
	to be coalessed) and a maximum commands to coaless value.
	Add a statistics timer that decides when to enable or
	disable interrupt coalessing based on load.

	Add a routine, ahd_reset_cmds_pending() which is used
	to update the CMDS_PENDING sequencer variable whenever
	error recovery compeltes SCBs without notifying the
	sequencer.  Since ahd_reset_cmds_pending is called
	during ahd_unpause() only if we've aborted SCBs, its
	call to ahd_flush_qoutfifo should not cause recursion
	through ahd_run_qoutfifo().  A panic has been added to
	ensure that this recursion does not occur.

	In ahd_search_qinfifo, update the CMDS_PENDING sequencer
	variable directly.  ahd_search_qinififo can be called
	in situations where using ahd_reset_cmds_pending() might
	cause recursion.  Since we can safely determine the
	exact number to reduce CMDS_PENDING by in this scenario
	without running the qoutfifo, the manual update is sufficient.

	Clean up diagnostics.
	Add ahd_flush_qoutfifo() which will run the qoutfifo
	as well as complete any commands sitting on the
	sequencer's COMPLETE_SCB lists or the good status FIFO.
	Use this routine in several places that did similar
	things in an add-hoc, but incomplete, fashion.  A call
	to this routine was also added to ahd_abort_scbs() to
	close a race.

	In ahd_pause_and_flushwork() only return once selections
	are safely disabled.  Flush all completed commands via
	ahd_flush_qoutfifo().

	Remove "Now packetized" diagnostic now that this
	information is incorperated into the actual negotiation
	messages that are displayed.

	When forcing renegotiation, don't clober the current
	ppr_options.  Much of the driver uses this information
	to determine if we are currently packetized or not.

	Remove some stray spaces at column 1 in ahd_set_tags.

	When complaining about getting a host message loop
	request with no pending messages, print out the
	SCB_CONTROL register down on the card.

	Modify the ahd_sent_msg() routine to handle a search
	for an outgoing identify message.  Use this to detect
	a msg reject on an identify message which typically
	indicates that the target thought we were packetized.
	Force a renegotiation in this case.

	In ahd_search_qinfifo(), wait more effectively for SCB
	DMA activities to cease.  We also disable SCB fetch
	operations since we are about to change the qinfifo
	and any fetch in progress will likely be invalidated.

	In ahd_qinfifo_count(), fix the qinfifo empty case.

	In ahd_dump_card_state(), print out CCSCBCTL in the
	correct mode.

	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.

	Add support for task management function completions.

	Modify ahd_handle_devreset so that it can handle
	lun resets in addition to target resets.  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 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.

	Indicate the features, bugs, and flags set in the softc
	that are used to control firmware patch download when
        booting verbose.

aic79xx.h:
	Add coalessing and HS_MAILBOX fields.

	Add per-softc variables for the stats "daemon".

	Add a debug option for interrupt coalessing activities.

	Add two new softc flags:
	o AHD_UPDATE_PEND_CMDS
	  Run ahd_reset_cmds_pending() on the next unpause.

	o AHD_RUNNING_QOUTFIFO
	  Used to catch recursion through ahd_run_qoutfifo().

aic79xx.reg:
	Correct register addresses related to the software timer
	and the DFDBCTL register.

	Add constants paramaterizing the software timer.

	Add scratch ram locations for storing interrupt coalessing
	tunables.

	Break INTMASK in SEQITNCTL out into INTMASK1 and INTMASK2.
	In at least the REV A, these are writable bits.  We make
	use of that for a swtimer workaround in the sequencer.

	Since HS_MAILBOX autoclears, provide a sequencer variable
	to store its contents.

	Add SEQINT codes for handling task management completions.

aic79xx.seq:
	Correct ignore wide residue processing check for
	a wide negotiation being in effect.  We must be
	in the SCSI register window in order to access the
	negotiation table.

	Use the software timer and a commands completed count to
	implement interrupt coalessing.  The command complete is
	deferred until either the maximum command threshold or a
	the expiration of a command deferral timer.  If we have
	more SCBs to complete to the host (sitting in COMPLETE_SCB
	lists), always try to coaless them up to our coalessing limit.
	If coalessing is enabled, but we have fewer commands oustanting
	than the host's min coalessing limit, complete the command
	immediately.

	Add code to track the number of commands outstanding.
	Commands are outstanding from the time they are placed
	into the execution queue until the DMA to post completion
	is setup.

	Add a workaround for intvec_2 interrupts on the H2A4.
	In H2A4, the mode pointer is not saved for intvec2, but
	is restored on iret.  This can lead to the restoration
	of a bogus mode ptr.  Manually clear the intmask bits and
	do a normal return to compensate.  We use intvec_2 to
	track interrupt coalessing timeouts.

	Since we cannot disable the swtimer's countdown, simply
	mask its interrupt once we no longer care about it firing.

	In idle_loop_cchan, update LOCAL_HS_MAILBOX everytime
	we are notified of an HS_MAILBOX update via the
	HS_MAILBOX_ACT bit in QOFF_CTLSTA.  We have to use a
	local copy of persistant portions of the HS_MAILBOX as
	the mailbox auto-clears on any read.

	Move the test for the cfg4istat interrupt up an instruction
	to hopefully close a race between the next outgoing selection
	and our disabling of selections.

	Add a missing ret to the last instruction in load_overrun_buf.

	Add notifications to the host of task management
	completions as well as the completions for commands
	that completed successfully before their corresponding
	TMF could be 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_inline.h:
	Call ahd_reset_cmds_pending() in ahd_unpause if required.

	Update cmdcmplt interrupt statistics in our interrupt
	handler.

	Allow callers to ahd_send_scb() to set the task management
	function.

aic79xx_pci.c:
	Disable SERR and pause the controller prior to performing
	our mmapped I/O test.  The U320 controllers do not support
	"auto-access-pause".

aic79xx_osm.c:
	Set the task management function now that
	ahd_send_scb() doesn't do it for us.  We
	also perform a lun reset in response to BDR
	requests to packetized devices.

0f76d6d822 Finally give CCD the disk mini-layer treatment:
CAUTION:

        Previously CCD would be different from all other disks in
        the system in that there were no "ccd0" device, only a
        "ccd0c" device.

        This is no longer so after this commit.  If you access a
        ccd device through the "/dev/ccd0c" device _and_ have not
        actually put a BSD disklabel on the device, you will have
        to use the name "/dev/ccd0".  If your CCD device contains
        a BSD disklabel there should be no difference.

        You need to recompile ccdconfig(8) using the changed
        src/sys/sys/ccdvar.h for the -g "show me" option to work.

        I have run the regression test I created before I started
        overhauling CCD and it flags no problems, but this code
        is mildly evil, so take care.  If you would cry if you lost
        what's on CCD, make a back before you upgrade.

Create separate cdevsw for the /dev/ccd.ctl device.

Remove the cloning function, the disk-minilayer will do all naming
for us.

Remove the ccdunit and ccdpart functions and carry the softc pointer
in the relevant dev_t's and structures.

Release all memory when a CCD device is unconfigured, previously
the softc would linger behind.

Remove all traces of BSD disklabel fiddling code.

Remove ccdpsize, the disk mini-layer does this for us.

Don't allocate memory with M_WAITOK in ccdstrategy().

Remove boundary checks which the disk mini-layer does for us.

Don't allocate space for more than 2 ccdbuf, RAID was never implemented.

NB: I have not tried to address any of the preexisting ailments of CCD.
