aic7xxx.seq aic7xxx_inline.h
aic7xxx_pci.c
Log:
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.
