sparc64, where the relocations for the metadata are different than on other
architectures; the relative offset is in the addend of an Elf_Rela record
instead of the original value of the location being patched.
Also fix printf formats in debug code.

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.

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.
