ahc_eisa.c:
Change aic7770_map_int to take an additional irq parameter.
Although we can get the irq from the eisa dev under FreeBSD,
we can't do this under linux, so the OSM interface must supply
this.
ahc_pci.c:
Move ahc_power_state_change() to the OSM. This allows us to
use a platform supplied function that does the same thing.
-current will move to the FreeBSD native API in the near
future.
aic7770.c:
Sync up with core changes to support Linux EISA.
We now store a 2 bit primary channel number rather
than a bit flag that only allows b to be the primary
channel. Adjust for this change.
aic7xxx.c:
Namespace and staticization cleanup. All exported symbols
use an "ahc_" prefix to avoid collisions with other modules.
Correct a logic bug that prevented us from dropping
ATN during some exceptional conditions during message
processing.
Take advantage of a new flag managed by the sequencer
that indicates if an SCB fetch is in progress. If so,
the currently selected SCB needs to be returned to the
free list to prevent an SCB leak. This leak is a rarity
and would only occur if a bus reset or timeout resulting
in a bus reset occurred in the middle of an SCB fetch.
Don't attempt to perform ULTRA transfers on ultra capable
adapters missing the external precision resistor required
for ultra speeds. I've never encountered an adapter
configured this way, but better safe than sorry.
Handle the case of 5MHz user sync rate set as "0" instead of 0x1c
in scratch ram.
If we lookup a period of 0 in our table (async), clear the scsi offset.
aic7xxx.h:
Adjust for the primary channel being represented as
a 2 bit integer in the flags member of the ahc softc.
Cleanup the flags definitions so that comment blocks are
not cramped.
Update seeprom definitions to correctly reflect the fact
that the primary channel is represented as a 2 bit integer.
Add AHC_ULTRA_DIASABLED softc flag to denote controllers
missing the external precision resistor.
aic7xxx.reg:
Add DFCACHETH to the definition of DFSTATUS for completness sake.
Add SEQ_FLAGS2 which currently only contains the SCB_DMA
(SCB DMA in progress) flag.
aic7xxx.seq:
Correct a problem when one lun has a disconnected untagged
transaction and another lun has disconnected tagged transactions.
Just because an entry is found in the untagged table doesn't
mean that it will match. If the match on the lun fails, cleanup
the SCB (return it to the disconnected list or free it), and snoop
for a tag message. Before this change, we reported an unsolicited
reselection. This bug was introduced about a month ago during an
overly aggressive optimization pass on the reselection code.
When cleaning up an SCB, we can't just blindly free the SCB. In
the paging case, if the SCB came off of the disconnected list, its
state may never have been updated in host memory. So, check the
disconnected bit in SCB_CONTROL and return the SCB to the disconnected
list if appropriate.
Manage the SCB_DMA flag of SEQ_FLAGS2.
More carefully shutdown the S/G dma engine in all cases by using
a subroutine. Supposedly not doing this can cause an arbiter hang
on some ULTRA2 chips.
Formatting cleanup.
On some chips, at least the aic7856, the transition from
MREQPEND to HDONE can take a full 4 clock cycles. Test
HDONE one more time to avoid this race. We only want our
FIFO hung recovery code to execute when the engine is
really hung.
aic7xxx_93cx6.c:
Sync perforce ids.
aic7xxx_freebsd.c:
Adjust for the primary channel being a 2 bit integer
rather than a flag for 'B' channel being the primary.
Namespace cleanup.
Unpause the sequencer in one error recovery path that
neglected to do so. This could have caused us to perform
a bus reset when a recovery message might have otherwise been
successful.
aic7xxx_freebsd.h:
Use AHC_PCI_CONFIG for controlling compilation of PCI
support consistently throughout the driver.
Move ahc_power_state_change() to OSM.
aic7xxx_inline.h
Namespace cleanup.
Adjust our interrupt handler so it will work in the edge
interrupt case. We must process all interrupt sources
when the interrupt fires or risk not ever getting an
interrupt again. This involves marking the fact
that we are relying on an edge interrupt in ahc->flags
and checking for this condition in addition to the
AHC_ALL_INTERRUPTS flag. This fixes hangs on the
284X and any other aic7770 installation where level
interrupts are not available.
aic7xxx_pci.c:
Move the powerstate manipulation code into the OSM. Several
OSes now provide this functionality natively.
Take another shot at using the data stored in scratch ram
if the SCB2 signature is correct and no SEEPROM data is
available. In the past this failed if external SCB ram
was configured because the memory port was locked. We
now release the memory port prior to testing the values
in SCB2 and re-acquire it prior to doing termination control.
Adjust for new 2 bit primary channel setting.
Trust the STPWLEVEL setting on v 3.X BIOSes too.
Configure any 785X ID in the same fashion and assume
that any device with a rev id of 1 or higher has the
PCI 2.1 retry bug.
o Separate the kernel stuff from the Yarrow algorithm. Yarrow is now
well contained in one source file and one header.
o Replace the Blowfish-based crypto routines with Rijndael-based ones.
(Rijndael is the new AES algorithm). The huge improvement in
Rijndael's key-agility over Blowfish means that this is an
extremely dramatic improvement in speed, and makes a heck of
a difference in its (lack of) CPU load.
o Clean up the sysctl's. At BDE's prompting, I have gone back to
static sysctls.
o Bug fixes. The streamlining of the crypto stuff enabled me to
find and fix some bugs. DES also found a bug in the reseed routine
which is fixed.
o Change the way reseeds clear "used" entropy. Previously, only the
source(s) that caused a reseed were cleared. Now all sources in the
relevant pool(s) are cleared.
o Code tidy-up. Mostly to make it (nearly) 80-column compliant.

in vr_init(). The VIA Rhine chip happens to be able to automatically
read its station address from the EEPROM automatically when reset,
so you don't need to program the filter if you want to keep using the
factory default address, but if you want to change it with "ifconfig vr0
ether xx:xx:xx:xx:xx:xx" then we need to manually set it in the init
routine.

palette. As a result, the colors on the video console can look rather
weird. For example, sysinstall on the alpha has a read background. We
can work around this partially by remapping the colors used by syscons for
the ANSI color escape sequences. Note that screen savers and anything that
sets the colors explicitly will still get incorrect colors, but programs
such as sysinstall will now use the correct colors. A more correct fix
would be to actually fix the VGA palette on boot by either swapping all
the red and blue attributes or by hardcoding a standard palette and
overwriting the entire palette.

bolted to a ne-2000 chip. This is necessary for the NetGear FA-410TX
and other cards.
This also requires you add mii to your kernel if you have an ed driver
configured.
This code will result in a couple of timeout messages for ed on the
impacted cards. Additional work will be needed, but this does work
right now, and many people need these cards.

This is a pretty invasive change, but there are three good
reasons to do this:
1. We'll never have > 16 bits of handle.
2. We can (eventually) enable the RIO (Reduced Interrupt Operation)
bits which return multiple completing 16 bit handles in mailbox
registers.
3. The !)$*)$*~)@$*~)$* Qlogic target mode for parallel SCSI spec
changed such that at_reserved (which was 32 bits) was split into
two pieces- and one of which was a 16 bit handle id that functions
like the at_rxid for Fibre Channel (a tag for the f/w to correlate
CTIOs with a particular command). Since we had to muck with that
and this changed the whole handler architecture, we might as well...
Propagate new at_handle on through int ct_fwhandle. Follow
implications of changing to 16 bit handles.
These above changes at least get Qlogic 1040 cards working in target
mode again. 1080/12160 cards don't work yet.

for all PCI cards. The softc fields `lnc_btag' and `lnc_bhandle'
were not initialised, `rap', `rdp' and `bdp' were initialised to
the wrong values, and the size of the DMA ring memory was calculated
incorrectly.

for selecting unit). Instead, use the resource hints mechanism.
One unfortunate situation here is that there is no resource_quad_value
function- which is what I needed for WWN boot time replacement. Worse-
you can't store the hint as just plain
hint.isp.0.nodewwn="0x50000000aaaa0001"
because this gets interpreted as an int- incorrectly because it can't
be converted to an int. I can't even get this as a string. To work
around this particular case for nodewwn && portwwn setting, this
rather grotesque form will be used:
hint.isp.0.nodewwn="w50000000aaaa0001"
hint.isp.0.portwwn="w50000000aaaa0002"
At the same time, if we have no hinted WWN, set the default WWN (which, btw,
gets overridden if the card has valid NVRAM, which is usual) to
0x400000007F000009ull (which translates to NAA == IPv4, 127.0.0.9).

Add the 'virtual nulmodem driver'
Particularly useful for debuging kernels using vmware.
If your name is Bruce evans and you are a WIZ at tty interfaces,
then you should probably rip this to shreds and offer lots of suggestions and
patches. I've been using this since 4.0-CURRENT and it's never caused
problems but I'm sure I got something wrong. This is similar to the pty/cty
device driver except that both sides are ttys. Even minor numbers
are side A and odd minor numbers are side B.
Work needs to be done regarding what happens to the other side when you
close a node.
to use with vmware, configure vmware to redirect COM2 out to side A of one
of these and boot a kernel with teh gdb remote port set to sio1.
AFTER dropping into the gdb kernel debugger in your test kernel,
fire up gdb with it's remote port pointing at the appropriate side B.
To catch all console output, you can boot the vmware kernel with a serial
console, (COM1) similarly redirected to a nulmodem, and use 'tip' to observe it.
This is practically unaltered since pre 4.0 days except for
changes made along the way needed to make it compile, so any suggestions
or offers of total rewrites will be listenned to :-)
