aic7xxx.h:
Split out core chip initialization into ahc_chip_init().
This will allow us to reset the chip correctly at times
other than initial chip setup.
aic7770.c
aic7xxx_pci.c:
Flesh out bus chip init methods for our two
bus attachments and use these, in addition to
bus suspend/resume hooks to get the core in
better shape for handling these events.
When disabling PCI parity error checking, use FAILDIS.
Although the chip docs indicate that clearing PERRESPEN
should also work, it does not.
Auto-disable pci parity error checking after informing
the user of AHC_PCI_TARGET_PERR_THRESH number of parity
errors observed as a target.
aic7xxx.h:
aic7xxx_pci.c
aic7770.c
aic7xxx.c
Add the instruction_ram_size softc field.
Remove the now unused stack_size softc field.
Modify ahc_loadseq to return a failure code
and to actually check the downloaded instruction
count against the limit set in our softc.
Modify callers of ahc_loadseq to handle load
failures as appropriate.
Set instruction RAM sizes for each chip type.
aic7xxx_pci.c:
Add some delay in the aic785X termination
control code. This may fix problems with
the 2930.
Be consistent in how we access config space
registers. 16bit registers are accessed using
16bit ops.
aic7xxx.c:
Correct spelling errors.
Have ahc_force_renegotiation() take a devinfo as is done
in the U320 driver. Use this argument to correct a bug
in the selection timeout handler where we forced a renegotiation
with the last device that had set SAVED_SCSIID. SAVED_SCSIID
is only updated once a selection is *sucessfull* and so is
stale for any selection timeout.
Cleanup the setup of the devinfo for busfree events. We
now use this devinfo for a call to ahc_force_renegotiation()
at the bottom of the routine, so it must be initialized in
all cases.
In ahc_pause_and_flushwork(), adjust the loop so that it
will exit in the hot-eject case even if the INT_PEND mask
is something other than 0xFF (as it is in this driver).
Correct a wrapping string constant.
Call ahc_fini_scbdata() after shutdown so that
any ahc_chip_init() routine that might access
SCB data will not access free'd memory.
Correctly setup our buffer tag to indicate that 39bit
addressing is available if in 39bit addressing mode.
Rearrange some variable declarations based on
type size.
aic7xxx.c
aic7xxx.h:
aic7xxx.reg:
Consistently use MAX_OFFSET for the user max syncrate
set from non-volatile storage. This ensures that the
offset does not conflict with AHC_OFFSET_UNKNOWN.
Change AHC_OFFSET_UNKNOWN to 0xFF. This is
a value that the curr->offset can never be,
unlike '0' which we previously used. This
fixes code that only checks for a non-zero
offset to determine if a sync negotiation
is required since it will fire in the unknown
case even if the goal is async.
Change MAX_OFFSET to 0x7f which is the max
offset U160 aic7xxx controllers can negotiate.
This ensures that curr->offset will not
match AHC_OFFSET_UNKNOWN.
aic7xxx_inline.h:
Have our inline interrupt handler return with a value
indicating whether we serviced a real interrupt. This
is required for Linux support.
Return earlier if the interrupt is not for us.
patch workarounds for each phy revision.
Obtained from: NetBSD & Broadcom Linux driver
- Disable AUTOPOLL when accessing the PHY as it may cause PCI errors.
Obtained from: NetBSD
- Check the UPDATED bit in the status block so the driver knows
that the status block as indeed changed since the last access.
Broadcom documentation states drivers should unset the UPDATED/CHANGED
bits after reading them.
- When changing media types, first loop the phy then set the media.
Broadcom documentation and Linux drivers do this and I observed
much better handling of link after this change.
- Broadcom documentation states that for 1000BaseT operation,
autonegotiation must be enabled. Fix hard coding of media so that
the driver only advertises 1000BaseT as the supported media type
and enable autonegotition.
- Only set Master/Slave on the 5701.
Obtained from Broadcom Linux driver.
- Use htole* macros where appropriate so that the driver could work on non-x86 architectures
- Use m_getcl() instead of MGETHDR/MCLGET macros

Note: this might print failure messages on some systems, unfortunatly
the info from the device, stating if flushing is supported, cannot be trusted
so the operation is always issued on all devices, just in case...
just return it. Don't try to reinitialize it. This should fix a
number of inconsistencies that some people encountered with "vinum
start".

of <machine/pc/bios.h> specific to i386 and added a conditional define
for BIOS_PADDRTOVADDR that depends on ISA_HOLE_START. The latter is
undefined on alpha and ia64. Since the former is defined the same on
both alpha and ia64, assume the ISA_HOLE_START dependent definition
is specific to amd64 and use the identity-mapping in all other cases.
This of course is getting uglier every day...
project by providing documentation (under NDA) and hardware for
testing. This commit is the first result of the cooperation, and
adds support for several of their new controllers that we didn't
support before (and probably newer would have without this arrangement).
Add support for the Promise SATA150 TX2/TX4 and the Promise TX4000
controllers. This also adds support for various motherboard fitted
Promise SATA/ATA chips.
Note that this code uses memory mapped registers to minimize overhead.
I belive FreeBSD has made another first in the Open Source world
by being able to release support for this :)

work out why.

As a result of the minor number changes, split out the superdevice
handling into a separate function, vinum_super_ioctl. This was most
of the code of vinumioctl.

init_drive: Rephrase error message text.
Remove dead code (inside #if 0).
Change name of find_drive_by_dev to the more descriptive
find_drive_by_name.

at all (ie reads yield constant values). Display the width as the
difference between max and min so that constant timers have width
zero.
o Get the address of the timer from the XPmTmrBlk field instead of
the V1_PmTmrBlk field. The former is a generic address and can
specify a memory mapped I/O address. Remove <machine/bus_pio.h>
to account for this. The timer is now properly configured on
machines with ACPI v2 tables, whether PIO or MEMIO. Note that
the acpica code converts v1 tables into v2 tables so the address
is always present in XPmTmrBlk.
o Replace the TIMER_READ macro with a call to the read_counter()
function and add a barrier to make sure that we observe proper
ordering of the reads.
