ahc_eisa.c:
ahc_pci.c:
ahd_pci.c:
aic7xxx.c:
aic79xx.c:
aic_osm_lib.c:
aic_osm_lib.h:
Use common OSM routines from aic_osm_lib for bus dma operations,
delay routines, accessing CCBs, byte swapping, etc.
aic7xxx_pci.c:
Provide a better description for the 2915/30LP on attach.
aic7xxx.c:
aic79xx.c:
aic7770.c:
aic79xx_pci.c:
aic7xxx_pci.c:
aic7xxx_93cx6.c:
Move FBSDID behind an ifdef so that these core files will
still compile under other OSes.
aic79xx.h:
aic79xx_pci.c:
aic79xx.seq:
To speed up non-packetized CDB delivery in Rev B, all CDB
acks are "released" to the output sync as soon as the
command phase starts. There is only one problem with this
approach. If the target changes phase before all data are
sent, we have left over acks that can go out on the bus in
a data phase. Due to other chip contraints, this only
happens if the target goes to data-in, but if the acks go
out before we can test SDONE, we'll think that the transfer
has completed successfully. Work around this by taking
advantage of the 400ns or 800ns dead time between command
phase and the REQ of the new phase. If the transfer has
completed successfully, SCSIEN should fall *long* before we
see a phase change. We thus treat any phasemiss that
occurs before SCSIEN falls as an incomplete transfer.
aic79xx.h:
Add the AHD_FAST_CDB_DELIVERY feature.
aic79xx_pci.c:
Set AHD_FAST_CDB_DELIVERY for all Rev. B parts.
aic79xx.seq:
Test for PHASEMIS in the command phase for
all AHD_FAST_CDB_DELIVERY controlelrs.
ahd_pci.c:
ahc_pci.c:
aic7xxx.h:
aic79xx.h:
Move definition of controller BAR offsets to core header files.
aic7xxx.c:
aic79xx.c:
In the softc free routine, leave removal of a softc from the
global list of softcs to the OSM (the caller of this routine).
This allows us to avoid holding the softc list_lock during device
destruction where we may have to sleep waiting for our recovery
thread to halt.
ahc_pci.c:
Use ahc_pci_test_register access to validate I/O mapped in
addition to the tests already performed for memory mapped
access.
Remove unused ahc_power_state_change() function. The PCI
layer in both 4.X and 5.X now offer this functionality.
ahd_pci.c:
Remove reduntant definition of controller BAR offsets. These
are also defined in aic79xx.h.
Remove unused ahd_power_state_change() function. The PCI
layer in both 4.X and 5.X now offer this functionality.
aic7xxx.c:
aic79xx.c:
aic79xx.h:
aic7xxx.h:
aic7xxx_osm.c:
aic79xx_osm.c:
Move timeout handling to the driver cores. In the case
of the aic79xx driver, the algorithm has been enhanced
to try target resets before performing a bus reset. For
the aic7xxx driver, the algorithm is unchanged. Although
the drivers do not currently sleep during recovery (recovery
is timeout driven), the cores do expect all processing to
be performed via a recovery thread. Our timeout handlers
are now little stubs that wakeup the recovery thread.
aic79xx.c:
aic79xx.h:
aic79xx_inline.h:
Change shared_data allocation to use a map_node so
that the sentinel hscb can use this map node in
ahd_swap_with_next_hscb. This routine now swaps
the hscb_map pointer in additon to the hscb
contents so that any sync operations occur on
the correct map.
physaddr -> busaddr
Pointed out by: Jason Thorpe <thorpej@wasabisystems.com>
aic79xx.c:
Make more use of the in/out/w/l/q macros for accessing
byte registers in the chip.
Correct some issues in the ahd_flush_qoutfifo() routine.
o Run the qoutfifo only once the command channel
DMA engine has been halted. This closes a window
where we might have missed some entries.
o Change ahd_run_data_fifo() to not loop to completion.
If we happen to start on the wrong FIFO and the other
FIFO has a snapshot savepointers, we might deadlock.
This required our delay between FIFO tests to be
moved to the ahd_flush_qoutfifo() routine.
o Update/add comments.
o Remove spurious test for COMPLETE_DMA list being empty
when completing transactions from the GSFIFO with
residuals. The SCB must be put on the COMPLETE_DMA
scb list unconditionally.
o When halting command channel DMA activity, we must
disable the DMA channel in all cases but an update
of the QOUTFIFO. The latter case is required so
that the sequencer will update its position in the
QOUTFIFO. Previously, we left the channel enabled
for all "push" DMAs. This left us vulnerable to
the sequencer handling an SCB push long after that
SCB was already processed manually by this routine.
o Correct the polarity of tests involving
ahd_scb_active_in_fifo(). This routine returns
non-zero for true.
Return to processing bad status completions through
the qoutfifo. This reduces the time that the sequencer
is kept paused when handling transactions with bad
status or underruns.
When waiting for the controller to quiece selections,
add a delay to our loop. Otherwise we may fail to wait
long enough for the sequencer to comply.
On H2A4 hardware, use the slow slewrate for non-paced
transfers. This mirrors what the Adaptec Windows
drivers do.
On the Rev B. only slow down the CRC timing for
older U160 devices that might need the slower timing.
We define "older" as devices that do not support
packetized protocol.
Wait up to 5000 * 5us for the SEEPROM to become unbusy.
Write ops seem to take much longer than read ops.
aic79xx.seq:
For controllers with the FAINT_LED bug, turn the diagnostic
led feature on during selection and reselection. This covers
the non-packetized case. The LED will be disabled for
non-packetized transfers once we return to the top level idle
loop. Add more comments about the busy LED workaround.
Extend a critical section around the entire
command channel idle loop process. Previously
the portion of this handler that directly manipulated
the linked list of completed SCBs was not protected.
This is the likely cause of the recent reports of
commands being completed twice by the driver.
Extend critical sections across the test for,
and the longjump to, longjump routines. This
prevents the firmware from trying to jump to
a longjmp handler that was just cleared by the
host.
Improve the locations of several critical section
begin and end points. Typically these changes
remove instructions that did not need to be
inside a critical section.
Close the "busfree after selection, but before busfree
interrupts can be enabled" race to just a single sequencer
instruction. We now test the BSY line explicitly before
clearing the busfree status and enabling the busfree
interrupt.
Close a race condition in the processing of HS_MAILBOX
updates. We now clear the "updated" status before the
copy. This ensures that we don't accidentally clear
the status incorrectly when the host sneaks in an update
just after our last copy, but before we clear the status.
This race has never been observed.
Don't re-enable SCSIEN if we lose the race to disable SCSIEN
in our interrupt handler's workaround for the RevA data-valid
too early issue.
aic79xx_inline.h:
Add comments indicating that the order in which bytes are
read or written in ahd_inw and ahd_outw is important. This
allows us to use these inlines when accessing registers with
side-effects.
aic79xx_pci.c:
The 29320 and the 29320B are 7902 not 7901 based products.
Correct the driver banner.
aic7xxx.h:
Enable the use of the auto-access pause feature
on the aic7870 and aic7880. It was disabled due
to an oversight.
aic7xxx.reg:
Move TARG_IMMEDIATE_SCB to alias LAST_MSG to
avoid leaving garbage in MWI_RESIDUAL. This
prevents spurious overflows whn operating target
mode on controllers that require the MWI_RESIDUAL
work-around.
aic7xxx.seq:
AHC_TMODE_WIDEODD_BUG is a bug, not a softc flag.
Reference the correct softc field when testing
for its presence.
Set the NOT_IDENTIFIED and NO_CDB_SENT bits
in SEQ_FLAGS to indicate that the nexus is
invalid in await busfree.
aic7xxx_93cx6.c:
Add support for the C56/C66 versions of the EWEN and EWDS
commands.
aic7xxx.c:
aic7xxx_pci.c:
Move test for the validity of left over BIOS data
to ahc_test_register_access(). This guarantees that
any left over CHIPRST value is not clobbered by our
register access test and lost to the test that was
in ahc_reset.

aic79xx_pci.c:
aic79xx.seq:
To speed up non-packetized CDB delivery in Rev B, all CDB
acks are "released" to the output sync as soon as the
command phase starts. There is only one problem with this
approach. If the target changes phase before all data are
sent, we have left over acks that can go out on the bus in
a data phase. Due to other chip contraints, this only
happens if the target goes to data-in, but if the acks go
out before we can test SDONE, we'll think that the transfer
has completed successfully. Work around this by taking
advantage of the 400ns or 800ns dead time between command
phase and the REQ of the new phase. If the transfer has
completed successfully, SCSIEN should fall *long* before we
see a phase change. We thus treat any phasemiss that
occurs before SCSIEN falls as an incomplete transfer.
aic79xx.h:
Add the AHD_FAST_CDB_DELIVERY feature.
aic79xx_pci.c:
Set AHD_FAST_CDB_DELIVERY for all Rev. B parts.

In the softc free routine, leave removal of a softc from the
global list of softcs to the OSM (the caller of this routine).
This allows us to avoid holding the softc list_lock during device
destruction where we may have to sleep waiting for our recovery
thread to halt.
ahc_pci.c:
Use ahc_pci_test_register access to validate I/O mapped in
addition to the tests already performed for memory mapped
access.
Remove unused ahc_power_state_change() function. The PCI
layer in both 4.X and 5.X now offer this functionality.

aic7xxx.h:
aic7xxx_osm.c:
aic79xx_osm.c:
Move timeout handling to the driver cores. In the case
of the aic79xx driver, the algorithm has been enhanced
to try target resets before performing a bus reset. For
the aic7xxx driver, the algorithm is unchanged. Although
the drivers do not currently sleep during recovery (recovery
is timeout driven), the cores do expect all processing to
be performed via a recovery thread. Our timeout handlers
are now little stubs that wakeup the recovery thread.
aic79xx.c:
aic79xx.h:
aic79xx_inline.h:
Change shared_data allocation to use a map_node so
that the sentinel hscb can use this map node in
ahd_swap_with_next_hscb. This routine now swaps
the hscb_map pointer in additon to the hscb
contents so that any sync operations occur on
the correct map.
physaddr -> busaddr
Pointed out by: Jason Thorpe <thorpej@wasabisystems.com>
aic79xx.c:
Make more use of the in/out/w/l/q macros for accessing
byte registers in the chip.
Correct some issues in the ahd_flush_qoutfifo() routine.
o Run the qoutfifo only once the command channel
DMA engine has been halted. This closes a window
where we might have missed some entries.
o Change ahd_run_data_fifo() to not loop to completion.
If we happen to start on the wrong FIFO and the other
FIFO has a snapshot savepointers, we might deadlock.
This required our delay between FIFO tests to be
moved to the ahd_flush_qoutfifo() routine.
o Update/add comments.
o Remove spurious test for COMPLETE_DMA list being empty
when completing transactions from the GSFIFO with
residuals. The SCB must be put on the COMPLETE_DMA
scb list unconditionally.
o When halting command channel DMA activity, we must
disable the DMA channel in all cases but an update
of the QOUTFIFO. The latter case is required so
that the sequencer will update its position in the
QOUTFIFO. Previously, we left the channel enabled
for all "push" DMAs. This left us vulnerable to
the sequencer handling an SCB push long after that
SCB was already processed manually by this routine.
o Correct the polarity of tests involving
ahd_scb_active_in_fifo(). This routine returns
non-zero for true.
Return to processing bad status completions through
the qoutfifo. This reduces the time that the sequencer
is kept paused when handling transactions with bad
status or underruns.
When waiting for the controller to quiece selections,
add a delay to our loop. Otherwise we may fail to wait
long enough for the sequencer to comply.
On H2A4 hardware, use the slow slewrate for non-paced
transfers. This mirrors what the Adaptec Windows
drivers do.
On the Rev B. only slow down the CRC timing for
older U160 devices that might need the slower timing.
We define "older" as devices that do not support
packetized protocol.
Wait up to 5000 * 5us for the SEEPROM to become unbusy.
Write ops seem to take much longer than read ops.
aic79xx.seq:
For controllers with the FAINT_LED bug, turn the diagnostic
led feature on during selection and reselection. This covers
the non-packetized case. The LED will be disabled for
non-packetized transfers once we return to the top level idle
loop. Add more comments about the busy LED workaround.
Extend a critical section around the entire
command channel idle loop process. Previously
the portion of this handler that directly manipulated
the linked list of completed SCBs was not protected.
This is the likely cause of the recent reports of
commands being completed twice by the driver.
Extend critical sections across the test for,
and the longjump to, longjump routines. This
prevents the firmware from trying to jump to
a longjmp handler that was just cleared by the
host.
Improve the locations of several critical section
begin and end points. Typically these changes
remove instructions that did not need to be
inside a critical section.
Close the "busfree after selection, but before busfree
interrupts can be enabled" race to just a single sequencer
instruction. We now test the BSY line explicitly before
clearing the busfree status and enabling the busfree
interrupt.
Close a race condition in the processing of HS_MAILBOX
updates. We now clear the "updated" status before the
copy. This ensures that we don't accidentally clear
the status incorrectly when the host sneaks in an update
just after our last copy, but before we clear the status.
This race has never been observed.
Don't re-enable SCSIEN if we lose the race to disable SCSIEN
in our interrupt handler's workaround for the RevA data-valid
too early issue.
aic79xx_inline.h:
Add comments indicating that the order in which bytes are
read or written in ahd_inw and ahd_outw is important. This
allows us to use these inlines when accessing registers with
side-effects.
aic79xx_pci.c:
The 29320 and the 29320B are 7902 not 7901 based products.
Correct the driver banner.
aic7xxx.h:
Enable the use of the auto-access pause feature
on the aic7870 and aic7880. It was disabled due
to an oversight.
aic7xxx.reg:
Move TARG_IMMEDIATE_SCB to alias LAST_MSG to
avoid leaving garbage in MWI_RESIDUAL. This
prevents spurious overflows whn operating target
mode on controllers that require the MWI_RESIDUAL
work-around.
aic7xxx.seq:
AHC_TMODE_WIDEODD_BUG is a bug, not a softc flag.
Reference the correct softc field when testing
for its presence.
Set the NOT_IDENTIFIED and NO_CDB_SENT bits
in SEQ_FLAGS to indicate that the nexus is
invalid in await busfree.
aic7xxx_93cx6.c:
Add support for the C56/C66 versions of the EWEN and EWDS
commands.
aic7xxx.c:
aic7xxx_pci.c:
Move test for the validity of left over BIOS data
to ahc_test_register_access(). This guarantees that
any left over CHIPRST value is not clobbered by our
register access test and lost to the test that was
in ahc_reset.

On the Rev B. only slow down the CRC timing for
older U160 devices that might need the slower timing.
We define "older" as devices that do not support
packetized protocol.
Wait up to 5000 * 5us for the SEEPROM to become unbusy.
Write ops seem to take much longer than read ops.
aic79xx.seq:
For controllers with the FAINT_LED bug, turn the diagnostic
led feature on during selection and reselection. This covers
the non-packetized case. The LED will be disabled for
non-packetized transfers once we return to the top level idle
loop. Add more comments about the busy LED workaround.
Extend a critical section around the entire
command channel idle loop process. Previously
the portion of this handler that directly manipulated
the linked list of completed SCBs was not protected.
This is the likely cause of the recent reports of
commands being completed twice by the driver.
Extend critical sections across the test for,
and the longjump to, longjump routines. This
prevents the firmware from trying to jump to
a longjmp handler that was just cleared by the
host.
Improve the locations of several critical section
begin and end points. Typically these changes
remove instructions that did not need to be
inside a critical section.
Close the "busfree after selection, but before busfree
interrupts can be enabled" race to just a single sequencer
instruction. We now test the BSY line explicitly before
clearing the busfree status and enabling the busfree
interrupt.
Close a race condition in the processing of HS_MAILBOX
updates. We now clear the "updated" status before the
copy. This ensures that we don't accidentally clear
the status incorrectly when the host sneaks in an update
just after our last copy, but before we clear the status.
This race has never been observed.
Don't re-enable SCSIEN if we lose the race to disable SCSIEN
in our interrupt handler's workaround for the RevA data-valid
too early issue.
aic79xx_inline.h:
Add comments indicating that the order in which bytes are
read or written in ahd_inw and ahd_outw is important. This
allows us to use these inlines when accessing registers with
side-effects.
aic79xx_pci.c:
The 29320 and the 29320B are 7902 not 7901 based products.
Correct the driver banner.
aic7xxx.h:
Enable the use of the auto-access pause feature
on the aic7870 and aic7880. It was disabled due
to an oversight.
aic7xxx.reg:
Move TARG_IMMEDIATE_SCB to alias LAST_MSG to
avoid leaving garbage in MWI_RESIDUAL. This
prevents spurious overflows whn operating target
mode on controllers that require the MWI_RESIDUAL
work-around.
aic7xxx.seq:
AHC_TMODE_WIDEODD_BUG is a bug, not a softc flag.
Reference the correct softc field when testing
for its presence.
Set the NOT_IDENTIFIED and NO_CDB_SENT bits
in SEQ_FLAGS to indicate that the nexus is
invalid in await busfree.
aic7xxx_93cx6.c:
Add support for the C56/C66 versions of the EWEN and EWDS
commands.
aic7xxx.c:
aic7xxx_pci.c:
Move test for the validity of left over BIOS data
to ahc_test_register_access(). This guarantees that
any left over CHIPRST value is not clobbered by our

aic79xx.seq:
To speed up non-packetized CDB delivery in Rev B, all CDB
acks are "released" to the output sync as soon as the
command phase starts. There is only one problem with this
approach. If the target changes phase before all data are
sent, we have left over acks that can go out on the bus in
a data phase. Due to other chip contraints, this only
happens if the target goes to data-in, but if the acks go
out before we can test SDONE, we'll think that the transfer
has completed successfully. Work around this by taking
advantage of the 400ns or 800ns dead time between command
phase and the REQ of the new phase. If the transfer has
completed successfully, SCSIEN should fall *long* before we
see a phase change. We thus treat any phasemiss that
occurs before SCSIEN falls as an incomplete transfer.

Move timeout handling to the driver cores. In the case
of the aic79xx driver, the algorithm has been enhanced
to try target resets before performing a bus reset. For
the aic7xxx driver, the algorithm is unchanged. Although
the drivers do not currently sleep during recovery (recovery
is timeout driven), the cores do expect all processing to
be performed via a recovery thread. Our timeout handlers
are now little stubs that wakeup the recovery thread.

contents so that any sync operations occur on
the correct map.
physaddr -> busaddr
Pointed out by: Jason Thorpe <thorpej@wasabisystems.com>
aic79xx.c:
Make more use of the in/out/w/l/q macros for accessing
byte registers in the chip.
Correct some issues in the ahd_flush_qoutfifo() routine.
o Run the qoutfifo only once the command channel
DMA engine has been halted. This closes a window
where we might have missed some entries.
o Change ahd_run_data_fifo() to not loop to completion.
If we happen to start on the wrong FIFO and the other
FIFO has a snapshot savepointers, we might deadlock.
This required our delay between FIFO tests to be
moved to the ahd_flush_qoutfifo() routine.
o Update/add comments.
o Remove spurious test for COMPLETE_DMA list being empty
when completing transactions from the GSFIFO with
residuals. The SCB must be put on the COMPLETE_DMA
scb list unconditionally.
o When halting command channel DMA activity, we must
disable the DMA channel in all cases but an update
of the QOUTFIFO. The latter case is required so
that the sequencer will update its position in the
QOUTFIFO. Previously, we left the channel enabled
for all "push" DMAs. This left us vulnerable to
the sequencer handling an SCB push long after that
SCB was already processed manually by this routine.
o Correct the polarity of tests involving
ahd_scb_active_in_fifo(). This routine returns
non-zero for true.
Return to processing bad status completions through
the qoutfifo. This reduces the time that the sequencer
is kept paused when handling transactions with bad
status or underruns.
When waiting for the controller to quiece selections,
add a delay to our loop. Otherwise we may fail to wait
long enough for the sequencer to comply.
On H2A4 hardware, use the slow slewrate for non-paced
transfers. This mirrors what the Adaptec Windows
drivers do.
On the Rev B. only slow down the CRC timing for

acks are "released" to the output sync as soon as the
command phase starts. There is only one problem with this
approach. If the target changes phase before all data are
sent, we have left over acks that can go out on the bus in
a data phase. Due to other chip contraints, this only
happens if the target goes to data-in, but if the acks go
out before we can test SDONE, we'll think that the transfer
has completed successfully. Work around this by taking
advantage of the 400ns or 800ns dead time between command
phase and the REQ of the new phase. If the transfer has
completed successfully, SCSIEN should fall *long* before we
see a phase change. We thus treat any phasemiss that
occurs before SCSIEN falls as an incomplete transfer.
aic79xx.h:

aic79xx_pci.c:

In the softc free routine, leave removal of a softc from the
global list of softcs to the OSM (the caller of this routine).
This allows us to avoid holding the softc list_lock during device
destruction where we may have to sleep waiting for our recovery
thread to halt.
ahc_pci.c:
Use ahc_pci_test_register access to validate I/O mapped in
addition to the tests already performed for memory mapped
access.
Remove unused ahc_power_state_change() function. The PCI
layer in both 4.X and 5.X now offer this functionality.

Move timeout handling to the driver cores. In the case
of the aic79xx driver, the algorithm has been enhanced
to try target resets before performing a bus reset. For
the aic7xxx driver, the algorithm is unchanged. Although
the drivers do not currently sleep during recovery (recovery
is timeout driven), the cores do expect all processing to
be performed via a recovery thread. Our timeout handlers
are now little stubs that wakeup the recovery thread.
aic79xx.c:
aic79xx.h:
aic79xx_inline.h:
Change shared_data allocation to use a map_node so
that the sentinel hscb can use this map node in
ahd_swap_with_next_hscb. This routine now swaps
the hscb_map pointer in additon to the hscb
contents so that any sync operations occur on
the correct map.

aic79xx.c:
Make more use of the in/out/w/l/q macros for accessing
byte registers in the chip.
Correct some issues in the ahd_flush_qoutfifo() routine.
o Run the qoutfifo only once the command channel
DMA engine has been halted. This closes a window
where we might have missed some entries.
o Change ahd_run_data_fifo() to not loop to completion.
If we happen to start on the wrong FIFO and the other
FIFO has a snapshot savepointers, we might deadlock.
This required our delay between FIFO tests to be
moved to the ahd_flush_qoutfifo() routine.
o Update/add comments.
o Remove spurious test for COMPLETE_DMA list being empty
when completing transactions from the GSFIFO with
residuals. The SCB must be put on the COMPLETE_DMA
scb list unconditionally.
o When halting command channel DMA activity, we must
disable the DMA channel in all cases but an update
of the QOUTFIFO. The latter case is required so
that the sequencer will update its position in the
QOUTFIFO. Previously, we left the channel enabled
for all "push" DMAs. This left us vulnerable to
the sequencer handling an SCB push long after that
SCB was already processed manually by this routine.
o Correct the polarity of tests involving
ahd_scb_active_in_fifo(). This routine returns
non-zero for true.
Return to processing bad status completions through
the qoutfifo. This reduces the time that the sequencer
is kept paused when handling transactions with bad
status or underruns.
When waiting for the controller to quiece selections,
add a delay to our loop. Otherwise we may fail to wait
long enough for the sequencer to comply.
On H2A4 hardware, use the slow slewrate for non-paced
transfers. This mirrors what the Adaptec Windows
drivers do.
On the Rev B. only slow down the CRC timing for
older U160 devices that might need the slower timing.
We define "older" as devices that do not support
packetized protocol.
Wait up to 5000 * 5us for the SEEPROM to become unbusy.
Write ops seem to take much longer than read ops.
aic79xx.seq:
For controllers with the FAINT_LED bug, turn the diagnostic
led feature on during selection and reselection. This covers
the non-packetized case. The LED will be disabled for
non-packetized transfers once we return to the top level idle
loop. Add more comments about the busy LED workaround.
Extend a critical section around the entire
command channel idle loop process. Previously
the portion of this handler that directly manipulated
the linked list of completed SCBs was not protected.
This is the likely cause of the recent reports of
commands being completed twice by the driver.
Extend critical sections across the test for,
and the longjump to, longjump routines. This
prevents the firmware from trying to jump to
a longjmp handler that was just cleared by the
host.
Improve the locations of several critical section
begin and end points. Typically these changes
remove instructions that did not need to be
inside a critical section.
Close the "busfree after selection, but before busfree
interrupts can be enabled" race to just a single sequencer
instruction. We now test the BSY line explicitly before
clearing the busfree status and enabling the busfree
interrupt.
Close a race condition in the processing of HS_MAILBOX
updates. We now clear the "updated" status before the
copy. This ensures that we don't accidentally clear
the status incorrectly when the host sneaks in an update
just after our last copy, but before we clear the status.
This race has never been observed.
Don't re-enable SCSIEN if we lose the race to disable SCSIEN
in our interrupt handler's workaround for the RevA data-valid
too early issue.
aic79xx_inline.h:
Add comments indicating that the order in which bytes are
read or written in ahd_inw and ahd_outw is important. This
allows us to use these inlines when accessing registers with

on the aic7870 and aic7880. It was disabled due
to an oversight.
aic7xxx.reg:
Move TARG_IMMEDIATE_SCB to alias LAST_MSG to
avoid leaving garbage in MWI_RESIDUAL. This
prevents spurious overflows whn operating target

work-around.

AHC_TMODE_WIDEODD_BUG is a bug, not a softc flag.
Reference the correct softc field when testing

Set the NOT_IDENTIFIED and NO_CDB_SENT bits
in SEQ_FLAGS to indicate that the nexus is
invalid in await busfree.
aic7xxx_93cx6.c:
Add support for the C56/C66 versions of the EWEN and EWDS
commands.
aic7xxx.c:
aic7xxx_pci.c:
Move test for the validity of left over BIOS data
to ahc_test_register_access(). This guarantees that
any left over CHIPRST value is not clobbered by our

aic79xx.seq:
To speed up non-packetized CDB delivery in Rev B, all CDB
acks are "released" to the output sync as soon as the
command phase starts. There is only one problem with this
approach. If the target changes phase before all data are
sent, we have left over acks that can go out on the bus in
a data phase. Due to other chip contraints, this only
happens if the target goes to data-in, but if the acks go
out before we can test SDONE, we'll think that the transfer
has completed successfully. Work around this by taking
advantage of the 400ns or 800ns dead time between command
phase and the REQ of the new phase. If the transfer has
completed successfully, SCSIEN should fall *long* before we
see a phase change. We thus treat any phasemiss that
occurs before SCSIEN falls as an incomplete transfer.
aic79xx.h:
Add the AHD_FAST_CDB_DELIVERY feature.
aic79xx_pci.c:
Set AHD_FAST_CDB_DELIVERY for all Rev. B parts.

In the softc free routine, leave removal of a softc from the
global list of softcs to the OSM (the caller of this routine).
This allows us to avoid holding the softc list_lock during device
destruction where we may have to sleep waiting for our recovery
thread to halt.
ahc_pci.c:
Use ahc_pci_test_register access to validate I/O mapped in
addition to the tests already performed for memory mapped
access.
Remove unused ahc_power_state_change() function. The PCI
layer in both 4.X and 5.X now offer this functionality.
ahd_pci.c:

Move timeout handling to the driver cores. In the case
of the aic79xx driver, the algorithm has been enhanced
to try target resets before performing a bus reset. For
the aic7xxx driver, the algorithm is unchanged. Although
the drivers do not currently sleep during recovery (recovery
is timeout driven), the cores do expect all processing to
be performed via a recovery thread. Our timeout handlers
are now little stubs that wakeup the recovery thread.
aic79xx.c:
aic79xx.h:
aic79xx_inline.h:
Change shared_data allocation to use a map_node so
that the sentinel hscb can use this map node in
ahd_swap_with_next_hscb. This routine now swaps
the hscb_map pointer in additon to the hscb
contents so that any sync operations occur on
the correct map.
physaddr -> busaddr
Pointed out by: Jason Thorpe <thorpej@wasabisystems.com>
aic79xx.c:
Make more use of the in/out/w/l/q macros for accessing
byte registers in the chip.
Correct some issues in the ahd_flush_qoutfifo() routine.
o Run the qoutfifo only once the command channel
DMA engine has been halted. This closes a window
where we might have missed some entries.
o Change ahd_run_data_fifo() to not loop to completion.
If we happen to start on the wrong FIFO and the other
FIFO has a snapshot savepointers, we might deadlock.
This required our delay between FIFO tests to be
moved to the ahd_flush_qoutfifo() routine.
o Update/add comments.
o Remove spurious test for COMPLETE_DMA list being empty
when completing transactions from the GSFIFO with
residuals. The SCB must be put on the COMPLETE_DMA
scb list unconditionally.
o When halting command channel DMA activity, we must
disable the DMA channel in all cases but an update
of the QOUTFIFO. The latter case is required so
that the sequencer will update its position in the
QOUTFIFO. Previously, we left the channel enabled
for all "push" DMAs. This left us vulnerable to
the sequencer handling an SCB push long after that
SCB was already processed manually by this routine.
o Correct the polarity of tests involving
ahd_scb_active_in_fifo(). This routine returns
non-zero for true.
Return to processing bad status completions through
the qoutfifo. This reduces the time that the sequencer
is kept paused when handling transactions with bad
status or underruns.
When waiting for the controller to quiece selections,
add a delay to our loop. Otherwise we may fail to wait
long enough for the sequencer to comply.
On H2A4 hardware, use the slow slewrate for non-paced
transfers. This mirrors what the Adaptec Windows
drivers do.
On the Rev B. only slow down the CRC timing for
older U160 devices that might need the slower timing.
We define "older" as devices that do not support
packetized protocol.
Wait up to 5000 * 5us for the SEEPROM to become unbusy.
Write ops seem to take much longer than read ops.
aic79xx.seq:
For controllers with the FAINT_LED bug, turn the diagnostic
led feature on during selection and reselection. This covers
the non-packetized case. The LED will be disabled for
non-packetized transfers once we return to the top level idle
loop. Add more comments about the busy LED workaround.
Extend a critical section around the entire
command channel idle loop process. Previously
the portion of this handler that directly manipulated
the linked list of completed SCBs was not protected.
This is the likely cause of the recent reports of
commands being completed twice by the driver.
Extend critical sections across the test for,
and the longjump to, longjump routines. This
prevents the firmware from trying to jump to
a longjmp handler that was just cleared by the
host.
Improve the locations of several critical section
begin and end points. Typically these changes
remove instructions that did not need to be
inside a critical section.
Close the "busfree after selection, but before busfree
interrupts can be enabled" race to just a single sequencer
instruction. We now test the BSY line explicitly before
clearing the busfree status and enabling the busfree
interrupt.
Close a race condition in the processing of HS_MAILBOX
updates. We now clear the "updated" status before the
copy. This ensures that we don't accidentally clear
the status incorrectly when the host sneaks in an update
just after our last copy, but before we clear the status.
This race has never been observed.
Don't re-enable SCSIEN if we lose the race to disable SCSIEN
in our interrupt handler's workaround for the RevA data-valid
too early issue.
aic79xx_inline.h:
Add comments indicating that the order in which bytes are
read or written in ahd_inw and ahd_outw is important. This
allows us to use these inlines when accessing registers with
side-effects.
aic79xx_pci.c:
The 29320 and the 29320B are 7902 not 7901 based products.
Correct the driver banner.
aic7xxx.h:
Enable the use of the auto-access pause feature
on the aic7870 and aic7880. It was disabled due
to an oversight.
aic7xxx.reg:
Move TARG_IMMEDIATE_SCB to alias LAST_MSG to
avoid leaving garbage in MWI_RESIDUAL. This
prevents spurious overflows whn operating target
mode on controllers that require the MWI_RESIDUAL
work-around.
aic7xxx.seq:
AHC_TMODE_WIDEODD_BUG is a bug, not a softc flag.
Reference the correct softc field when testing
for its presence.
Set the NOT_IDENTIFIED and NO_CDB_SENT bits
in SEQ_FLAGS to indicate that the nexus is
invalid in await busfree.
aic7xxx_93cx6.c:
Add support for the C56/C66 versions of the EWEN and EWDS
commands.
aic7xxx.c:
aic7xxx_pci.c:
Move test for the validity of left over BIOS data
to ahc_test_register_access(). This guarantees that
any left over CHIPRST value is not clobbered by our
register access test and lost to the test that was
in ahc_reset.
