56ebfcc6d5 Apply the following change from 06/28/2003 04:42:11 by gibbs to the
FreeBSD ahd driver:

Correct a typo in a comment.

Add a comment in ahd_clear_critical_sections() about
our need to leave ENBUSFREE set in SIMODE1 while single
stepping.

Re-arrange some delay loops so that we always perform
a read after any register write and before the delay.
This should make the delay loop more accurate.

When completing message processing for a packetized
commention, return the controller to a state where
invalid non-packetized phases will still cause protocol
violations.  These are the same operations as those
performed in the clear_target_state routine in the
firmware.

Now that we have a chip with working ABORTPENDING
support (the 7901B), comment out the automatic use
of this feature until we can adequately test it.
The previous checkin updated the bug mask for the
7901B so this code was exercised.

When resetting the bus, perform an ahd_flush_device_writes()
call so that our reset assertion delay is acurately
timed from when the reset bit is written to the controller.

aic79xx_pci.c:
        Split out the general aic790X setup into it's own
        setup handler that works on single and dual controllers.
        Adjust all other PCI setup handlers to initialize the
        chips basic features and type before calling the generic
        handler.

        Turn off a few Rev B workarounds that are not required
        on the 7901B.

FreeBSD ahd driver:

Add parenthesis so that we get all of the bits all
of the contents of the CCSCBCTL register into our
local varaible.  The other bits are used in later tests.
This avoids a potential deadlock in ahd_run_qoutfifo()
if we happen to catch the DMA engine in just the right
state.

FreeBSD ahd driver:

When single stepping, only leave ENBUSFREE enabled
if it was already enabled.  We don't want to set it
when it shouldn't be set, we just don't want to
inadvertantly turn it off.  This should fix a recent
report of the aic7xxx driver repeatedly complaining of
"unexpected busfree while idle" in one configuration.

720b377380 Apply the following change made 06/06/2003 23:51:13 by gibbs to the
FreeBSD ahd driver:

Work around SCSI spec violation by the Quantum Atlas 10K.
This drive delays going async after receiving a WDTR
message.  We now send an SDTR message after a WDTR even
if our goal is to go async.  This should work even for
confused devices.

If we get an unexpected busfree when attempting a WDTR
or SDTR, only set the goal negotiation parameters we were
trying to negotiate to off.  This means that should a WDTR
message fail, we will still try an SDTR if our goal is
non-async.

Fix a few more places where we were looking at goal.period
instead of goal.offset for determining if we should be
negotiating sync.  This should not have any impact on
our behavior, but the offset is more definitive and should
be used.

FreeBSD ahd driver:

Correct/Simplify ignore wide residue message handling

aic79xx.c:
	In ahd_handle_ign_wide_residue():
	o Use SCB_XFERLEN_ODD SCB field to determine transfer
	  "oddness" rather than the DATA_COUNT_ODD logic.
	  SCB_XFERLEN_ODD is toggled on every ignore wide
	  residue message so that multiple ignore wide residue
	  messages for the same transaction are properly supported.
	o If the sg list has been exausted, the sequencer
	  doesn't bother to update the residual data count
	  since it is known to be zero.  Perform the zeroing
	  manually before calculating the remaining data count.
	o Use multibyte in/out macros instead of shifting/masking
	  by hand.

aic79xx_inline.h:
	In ahd_setup_scb_common(), setup the SCB_XFERLEN_ODD field.

aic79xx.reg:
	Use the SCB_TASK_ATTRIBUTE field as a bit field in the
	non-packetized case.  We currently only define one bit,
	SCB_XFERLEN_ODD.

	Remove the ODD_SEG bit field that was used to carry the odd
	transfer length information through the SG cache.  This
	is obviated by SCB_XFERLEN_ODD field.

	Remove the DATA_COUNT_ODD scratch ram byte that was used
	dynamicaly compute data transfer oddness.  This is obviated
	by SCB_XFERLEN_ODD field.

aic79xx.seq:
	Remove all updates to the DATA_COUNT_ODD scratch ram field.
	Remove all uses of ODD_SEG.  These two save quite a few
	sequencer instructions.

	Use SCB_XFERLEN_ODD to validate the end of transfer
	ignore wide residue message case.

to be more efficient by having the sequencer copy the
single byte of valid lun data into the long lun field.

aic79xx.c:
	Memset our hardware SCB to 0 so that untouched
	fields don't confuse diagnostic output.  With the
	old method for handling the Rev A bug, if the long
	lun field was not 0, this could result in bogus
	lun information being sent to drives.

	Use the same SCB transfer size for all chip types
	now that the long lun is not DMA'ed to the chip.

e88c8722b7 Apply the following change checked in 2003/05/04 00:20:07 by gibbs
to the FreeBSD ahd driver:

Correct spelling errors.

Switch to handling bad SCSI status as a sequencer interrupt
instead of having the kernel proccess these failures via
the completion queue.  This is done because:

 o The old scheme required us to pause the sequencer and clear
   critical sections for each SCB.  It seems that these pause
   actions, if coincident with a sequencer FIFO interrupt, would
   result in a FIFO interrupt getting lost or directing to the
   wrong FIFO.  This caused hangs when the driver was stressed
   under high "queue full" loads.
 o The completion code assumed that it was always called with
   the sequencer running.  This may not be the case in timeout
   processing where completions occur manually via
   ahd_pause_and_flushwork().
 o With this scheme, the extra expense of clearing critical
   sections is avoided since the sequencer will only self pause
   once all pending selections have cleared and it is not in
   a critical section.

  aic79xx.c
        Add code to handle the new BAD_SCB_STATUS sequencer
        interrupt code.  This just redirects the SCB through
        the already existing ahd_complete_scb() code path.
        Remove code in ahd_handle_scsi_status() that paused
        the sequencer, made sure that no selections where
        pending, and cleared critical sections.  Bad
        status SCBs are now only processed when all of these
        conditions are true.

  aic79xx.reg:
        Add the BAD_SCB_STATUS sequencer interrupt code.

  aic79xx.seq:
        When completing an SCB upload to the host, if
        we are doing this because the SCB contains non-zero
        SCSI status, defer completing the SCB until there
        are no pending selection events.  When completing
        these SCBs, use the new BAD_SCB_STATUS sequencer
        interrupt.  For all other uploaded SCBs (currently
        only for underruns), the SCB is completed via the
        normal done queue.  Additionally, keep the SCB that
        is currently being uploaded on the COMPLETE_DMA_SCB
        list until the dma is completed, not just until the
        DMA is started.  This ensures that the DMA is restarted
        properly should the host disable the DMA transfer for
        some reason.

        In our RevA workaround for Maxtor drives, guard against
        the host pausing us while trying to pause I/O until the
        first data-valid REQ by clearing the current snapshot
        so that we can tell if the transfer has completed prior
        to us noticing the REQINIT status.

        In cfg4data_intr, shave off an instruction before getting
        the data path running by adding an entrypoint to the
        overrun handler to also increment the FIFO use count.

        In the overrun handler, be sure to clear our LONGJMP
        address in both exit paths.

Perform a few sequencer optimizations.

  aic79xx.c:
        Print the full path from the SCB when a packetized
        status overrun occurs.

        Remove references to LONGJMP_SCB which is being
        removed from firmware usage.

        Print the new SCB_FIFO_USE_COUNT field in the
        per-SCB section of ahd_dump_card_state().  The
        SCB_TAG field is now re-used by the sequencer,
        so it no longer makes sense to reference this
        field in the kernel driver.

  aic79xx.h:
        Re-arrange fields in the hardware SCB from largest
        size type to smallest.  This makes it easier to
        move fields without changing field alignment.

        The hardware scb tag field is now down near the
        "spare" portion of the SCB to facilitate reuse
        by the sequencer.

  aic79xx.reg:
        Remove LONGJMP_ADDR.

        Rearrange SCB fields to match aic79xx.h.
        Add SCB_FIFO_USE_COUNT as the first byte
        of the SCB_TAG field.

  aic79xx.seq:
        Add a per-SCB "Fifos in use count" field and use
        it to determine when it is safe (all data posted)
        to deliver status back to the host.  The old method
        involved polling one or both FIFOs to verify that
        the current task did not have pending data.  This
        makes running down the GSFIFO very cheap, so we
        will empty the GSFIFO in one idle loop pass in
        all cases.

        Use this simplification of the completion process
        to prune down the data FIFO teardown sequencer for
        packetized transfers.  Much more code is now shared
        between the data residual and transfer complete cases.

        Correct some issues in the packetized status handler.
        It used to be possible to CLRCHN our FIFO before status
        had fully transferred to the host.  We also failed to
        handle NONPACKREQ phases that could occur should a CRC
        error occur during transmission of the status data packet.

Correct a few big endian issues:

  aic79xx.c:
  aic79xx_inline.h:
  aic79xx_pci.c:
  aic79xx_osm.c:
        o Always get the SCB's tag via the SCB_GET_TAG acccessor
        o Add missing use of byte swapping macros when touching
          hscb fields.
        o Don't double swap SEEPROM data when it is printed.
          Correct a big-endian bug.  We cannot assign a
        o When assigning a 32bit LE variable to a 64bit LE
          variable, we must be explict about how the words
          of the 64bit LE variable are initialized.  Cast to
          (uint32_t*) to do this.

aic79xx.c:
        In ahd_clear_critical_section(), hit CRLSCSIINT
        after restoring the interrupt masks to avoid what
        appears to be a glitch on SCSIINT.  Any real SCSIINT
        status will be persistent and will immidiately
        reset SCSIINT.  This clear should only get rid of
        spurious SCSIINTs.

        This glitch was the cause of the "Unexpected PKT busfree"
        status that occurred under high queue full loads

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

        Reset the bus on an IOERR since the chip doesn't
        seem to reset to the new voltage level without
        this.
        Change offset calculation for scatter gather maps
        so that the calculation is correct if an integral
        multiple of sg lists does not fit in the allocation
        size.

        Adjust bus dma tag for data buffers based on 39BIT
        addressing flag in our softc.

        Use the QFREEZE count to simplify ahd_pause_and_flushworkd().
        We can thus rely on the sequencer eventually clearing ENSELO.

        In ahd_abort_scbs(), fix a bug that could potentially
        corrupt sequencer state.  The saved SCB was being
        restored in the SCSI mode instead of the saved mode.
        It turns out that the SCB did not need to be saved at all
        as the scbptr is already restored by all subroutines
        called during this function that modify that register.

ee0f53cd8c Make this work on systems where bus_dmamap_sync() is not a noop.
In particular, when doing the "swap hscbs" trick, the scb must
reference the correct hscb_map when it gets a new hscb, otherwise
when you go to sync an hscb later, you could end up using the wrong
dmamap.

In order to make this work, we have to convert the shared_data stuff
to use a map_node, because of the "sentinel" trick played with the
initial "next_hscb".

This driver now works on XScale-based platforms.

960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V
