1ead03c2ba Add support for changing the way that ToPIC csc interrupts are routed.
# Note: The ToPIC 100 and the ToPIC 97 datasheets are in disagreement
# as to if this bit is supposed to be set or cleared to enable INTA routing
# so I made my best guess.

Also, comments about the various chipsets, including some grumpy ones
about how vague the O2micro datasheets are.

592823383b Move to using a chip function + function pointers to deal with the
function and csc interrupt routing path (eg, ISA or PCI) so that we
can more easily switch between the two.

When we don't have a card ISR, put the function interrupt into ISA
mode.  This effectively masks the interrupt since it happens once, and
not again until we have an ISR.  This should help hangs, and might
help people that unwisely update the kernel w/o updating pccardd.
This is done at mapirq time.

Force CL-PD6729/30 to use ISA interrupt routing and maybe even detect
the number of pccard slots properly (this is still WIP).  We aren't
going to support PCI interrupts for this release.  A future release
should support them, however.  Shibata-san's 3.3V fixes are not
included.

Add a hack which should, in i386, rewrite IRQ 0 cardbus bridges to be
IRQ 255, which should cause interrupts to be routed.  This is mostly
untested since my one tester disappeared after reporting nothing
changed.

Implement, but do not use, a power method called cardbus.  It looked
like a great way to get around the 3.3V problem, but it seems that you
can only use it to power cardbus cards (I get no CIS when I enable it,
so maybe we're programming things bogusly).

GC the intr and argp stuff from the slot database.

Improve the ToPIC support with the power hacks that Nakagawa-san
published in FreeBSD Press and that Hiroyuki Aizu-san ported to
-stable.  The ToPIC hacks were for 3.3V support in ToPIC 100, but it
looks like the '97 also has identical registers, so use them too.

Add some #defines for the cardbus power stuff.

Finally implement making CSC on the Ricoh chips ISA or PCI.  This will
allow polling mode to work on vaios, I think.

Add some minor debugging.  This should likely be cleaned up or put
behing a bootverbose.

Some of this work, and earlier work, was influanced by Chiharu
Shibata-san's power handing patches posted to bsd-nomads:15866.

MFC: Soon, if possible.

880a354a4a Implement a slightly different window spill/fill algorithm for dealing
with user windows in kernel mode.  We split the windows using %otherwin,
but instead of spilling user window directly to the pcb, we attempt to
spill to user space.  If this fails because a stack page is not resident
(or the stack is smashed), the fault handler at tl 2 will detect the
situation and resume at tl 1 again where recovery code can spill to the
pcb.  Any windows that have been saved to the pcb will be copied out to
the user stack on return from kernel mode.

Add a first stab at 32 bit window handling.  This uses much of the same
recovery code as above because the alignment of the stack pointer is used
to detect 32 bit code.  Attempting to spill a 32 bit window to a 64 bit
stack, or vice versa, will cause an alignment fault.  The recovery code
then changes the window state to vector to a 32 bit spill/fill handler
and retries the faulting instruction.

Add ktr traces in useful places during trap processing.

Adjust comments to reflect new code and add many more.

ccc64d13f3 Implement pv_bit_count which is used by pmap_ts_referenced.
Remove the modified tte bit and add a softwrite bit.  Mappings are only
writeable if they have been written to, thus in general modify just
duplicates the write bit.  The softwrite bit makes it easier to distinguish
mappings which should be writeable but are not yet modified.

Move the exec bit down one, it was being sign extended when used as an
immediate operand.

Use the lock bit to mean tsb page and remove the tsb bit.  These are the
only form of locked (tsb) entries we support and we need to conserve bits
where possible.

Implement pmap_copy_page and pmap_is_modified and friends.

Detect mappings that are being being upgraded from read-only to read-write
due to copy-on-write and update the write bit appropriately.

Make trap_mmu_fault do the right thing for protection faults, which is
necessary to implement copy on write correctly.  Also handle a bunch
more userland trap types and add ktr traces.

181640a81c Clarify issues about whether we have SCCLUN (65535 luns) or non-SCCLUN (16
luns) firmware for the Fibre Channel cards.

We used to assume that if we didn't download firmware, we couldn't know
what the firmware capability with respect to SCCLUNs is- and it's important
because the lun field changes in the request queue entry based upon which
firmware it is.

At any rate, we *do* get back firmware attributes in mailbox register 6
when we do ABOUT FIRMWARE for all 2200/2300 cards- and for 2100 cards
with at least 1.17.0 firmware. So- we now assume non-SCCLUN behaviour
for 2100 cards with firmware < 1.17.0- and we check the firmware attributes
for other cards (loaded firmware or not).

This also allows us to get rid of the crappy test of isp_maxluns > 16-
we simply can check firmware attributes for SCCLUN behaviour.

This required an 'oops' fix to the outgoing mailbox count field for
ABOUT FIRMWARE for FC cards.

Also- while here, hardwire firmware revisions for loaded code for SBus
cards. Apparently the 1.35 or 1.37 f/w we've been loading into isp1000
just doesn't report firmware revisions out to mailbox regs 1, 2 and 3
like everyone else. Grumble. Not that this fix hardly matters for FreeBSD.

9d92f16230 Fix bus timeout bug which might happen when nsp do suspend I/O burst write.
A nsp chip does suspend I/O write by 512bytes burst write,
though the chip only has 48 bytes FIFO. The chip assert I/O WAIT
signal to PC-Card bus after the CPU writes more than 48 bytes to
the chip if the SCSI device does not respond immediately in supsend
I/O burst write. If the device does not respond for a while it might
cause PC-Card bus timeout.

The previous work around was to wait the request from SCSI device.
But there are some devices which request bytes for synchronous transfer
immediately. So current work aound is to fill 32bytes FIFO, wait for
FIFO empty and burst write 512-32 bytes for every 512 bytes block.

93f4fd1cb6 o Screw over users of the kern.{security.,}suser_permitted sysctl again,
by renaming it to kern.security.suser_enabled.  This makes the name
  consistent with other use: "permitted" now refers to a specific right
  or privilege, whereas "enabled" refers to a feature.  As this hasn't
  been MFC'd, and using this destroys a running system currently, I believe
  the user base of the sysctl will not be too unhappy.

356861db03 Remove the MPSAFE keyword from the parser for syscalls.master.
Instead introduce the [M] prefix to existing keywords.  e.g.
MSTD is the MP SAFE version of STD.  This is prepatory for a
massive Giant lock pushdown.  The old MPSAFE keyword made
syscalls.master too messy.

Begin comments MP-Safe procedures with the comment:
/*
 * MPSAFE
 */
This comments means that the procedure may be called without
Giant held (The procedure itself may still need to obtain
Giant temporarily to do its thing).

sv_prepsyscall() is now MP SAFE and assumed to be MP SAFE
sv_transtrap() is now MP SAFE and assumed to be MP SAFE

ktrsyscall() and ktrsysret() are now MP SAFE (Giant Pushdown)
trapsignal() is now MP SAFE (Giant Pushdown)

Places which used to do the if (mtx_owned(&Giant)) mtx_unlock(&Giant)
test in syscall[2]() in */*/trap.c now do not.  Instead they
explicitly unlock Giant if they previously obtained it, and then
assert that it is no longer held to catch broken system calls.

Rebuild syscall tables.

83e9f270b3 Clear SA_FLAG_ERR_PENDING for MTREW, MTERASE and MTRETENS ioctl cases.
Clear residual counts after a successful samount (the user doesn't
care that we got an N-kbyte residual on our test read).

Change a lot of error handling code.

1. If we end up in saerror, check more carefully about the kind of
error. If it is a CAM_SCSI_STATUS_ERROR and it is a read/write
command, we'll be handling this in saerror.  If it isn't a read/write
command, check to see whether this is just an EOM/EOP check condition-
if it is, just set residual and return normally. A residual and
then a NO SENSE check condiftion with the ASC of 0 and ASCQ of
between 1 and 4 are normal 'signifying' events, not errors per se,
and we shouldn't give the command to cam_periph_error to do something
relatively unpredictable with.

2. If we get a Bus Reset, had a BDR sent, or get the cam status of
CAM_REQUEUE_REQ, check the retry count on the command. The default
error handler, cam_periph_error, doesn't honor retry count in these
cases. This may change in the future, but for now, make sure we
set EIO and return without calling cam_periph_error if the retry
count for the command with an error is zero.

3. Clean up the pending error case goop and handle cases more
sensibly.

The rules are:

 If command was a Write:

  If we got a SSD_KEY_VOLUME_OVERFLOW, the resid is
  propagated and we set ENOSPC as the error.

  Else if we got an EOM condition- just mark EOM pending.

	And set a residual of zero. For the longest time I was just
        propagating residual from the sense data- but my tape
        comparison tests were always failing because all drives I
        tested with actually *do* write the data anyway- the EOM
        (early warning) condition occurred *prior* to all of the
        data going out to media- that is, it was still buffered by
        the drive. This case is described in SCSI-2, 10.2.14,
        paragraph #d for the meaning of 'information field'. A
        better fix for this would be to issue a WFM command of zero
        to cause the drive to flush any buffered data, but this
        would require a fairly extensive rewrite.

 Else if the command was a READ:

  If we got a SSD_KEY_BLANK_CHECK-
	If we have a One Filemark EOT model- mark EOM as pending,
	otherwise set EIO as the erorr.
  Else if we found a Filemark-
	If we're in Fixed Block mode- mark EOF pending.

 If we had an ILI (Incorrect Length Indicator)-
  If the residual is less than zero, whine about tape record
  being too big for user's buffer, otherwise if we were in
  Fixed Block mode, mark EIO as pending.

All 'pending' conditions mean that the command in question completes
without error indication. It had succeeded, but a signifying event
occurred during its execution which will apply to the *next* command
that would be exexcuted. Except for the one EOM case above, we always
propagate residual.

Now, way back in sastart- if we notice any of the PENDING bits set,
we don't run the command we've just pulled off the wait queue. Instead,
we then figure out it's disposition based upon a previous command's
association with a signifying event.

 If SA_FLAG_EOM_PENDING is set, we don't set an error. We just complete
 the command with residual set to the request count (not data moved,
 but no error). We continue on.

 If SA_FLAG_EOF_PENDING- if we have this, it's only because we're in
 Fixed Block mode- in which case we traverse all waiting buffers (which
 we can get in fixed block mode because physio has split things up) and
 mark them all as no error, but no data moved and complete them.

 If SA_FLAG_EIO_PENDING, just mark the buffer with an EIO error
 and complete it.

Then we clear all of the pending state bits- we're done.

d3b6477a19 It turns out that while Toshiba laptops don't want to route interrupts
multiple times, others do.  The last strategy, which was to assume
that already routed interrupts were good and just return them doesn't
work for some laptops.  So, instead, we have a new strategy: we notice
that we have an interrupt that's already routed.  We go ahead and try
to route it, none the less.  We will assume that it is correctly
routed, even if the route fails.  We still assume that other failures
in the bios32 call are because the interrupt is NOT routed.

Note: some laptops do not support the bios32 interface to PCI BIOS and
we need to call it via the INT 2A interface.  That is another windmill
to till at later.

Also correct a minor typo and minor whitespace nits.

Strong MFC candidate.

d93d282620 Add support for the 3c656B cardbus adapter. This is one half of a
dual function card. It needs pretty much the same flags as the 656C,
except that it seems to need both the INVERT_MII_PWR and INVERT_LED_PWR
flags set. Tested with cardbus in -current as of today.

Also added support for the 3c656, which looks to be the same as
the 656B, except it doesn't need the EEPROM_8BIT flag. I think. This
one is untested, but the added support should not break any of the
other cards.

00c4116b3e Systems based on the ICH2/ICH2-M chip from Intel have a defect where
the chip can cause a PCI protocol violation in under certain scenarios.
The workaround is to rewrite the EEPROM to disable Dynamic Standby Mode.

Once the EEPROM is rewritten, the system needs to be rebooted in order
to pick up the new settings.

This has been tested on several ICH2/ICH2-M systems, found in 815E based
boards, and usually identified by the presence of the 82562 ET/EM PHY.

Thanks to: Mike Tansca, Paul Saab for samples of the problematic boards.
