Convert to a read-only algorithm for validing entries in the

Clarify some comments.
Don't clear BUSFREE interrupt enable in SIMODE1 in the SELTO
handler. Just clearing the interrupt status is sufficient and
this avoids the chance of disabling busfree detection in connection
that occurs while we are handling the busfree interrupt.
Clear all possible interrupt sources when handling a busfree
interrupt. The hardware clears some but not all of them.
Don't panic if we get into the default SCSIINT handler.
Dump the card state and clear all interrupt sources in the
hope that we can continue.
LASTPHASE != PREVPHASE. Use the correct PREVPHASE for testing
against values in the PERRDIAG register.
According to SPI4, the bus free that is required after certain
PPR negotiations will only occur at the end of all message phases.
Handle the bus free if it occurs after a transaction in either
the message-in or message-out phases. The busfree can also occur
if the status of IU_REQ changes due to a WDTR or SDTR message.
We now set the expect busfree flag in ahd_set_syncrate so that
it works regardless of message type.
Correct a problem with missing certain busfree events. The
chip supports single-stepping even if a SCSIINT is pending.
This obviates the need to clear all of the SCSI interrupt enables
prior to single stepping. Since ENBUSFREE can only be disabled
manually and not re-enabled, avoiding touching this bit in the
single-step case yields reliable bus free detection.
Enhance ahd_clear_intstat to clear all SCSIINT sources.
Only use ahd_update_pending_scbs() if we are active on the
bus. We cannot modify the "MK_MESSAGE" bits on SCBs in the
execution queue if a selection might be in process since
the sequencer uses this bit to detect PPR negotiation to
a target with an outstanding IU_REQ agreement.
Allocate the SCB delivery mechansim's sentinal SCB specially
so we don't waste a valid SCB for this task.
Move tranceive state settle logic to ahd_chip_init() since
this needs to occur after every chip reset, not just the
chip reset that happens during primary driver initialization.
Correct a bug with transmitting lun information in packetized
connections.
Restrict busy target table operations to the range of luns
that can be used for non-packetized connections. Larger luns
can only be accessed in packetized mode.
Correct a busy target table addressing bug.
Be more careful about how we shutdown the DMA engines during
bus reset events.
Only freeze the SIMQ once regardless of the number of bus
reset events that occur while we are polling for the resets
to stop.
Don't rely on the sequencer remaining paused() during our
reset poll. It is safe for the sequencer to run during this
time, and many callers to the bus reset code would need to
be modified to make this assumption universally true.
Even if we are not going to clobber SCB state when an auto-request
sense SCB has a check condition, we must still unfreeze the queue.
Re-arrange the BAD STATUS handler to handle this case appropriately.
Modify the SCB download size depending on whether long luns are

When pausing the card to perform error recovery, ensure that we

We are having panics with the driver under stress with jumbo frames.
Unfortunately we didnot catch it during our regular test cycle.
I am going to MFC the backout immediately.
- Add an ACPI PCI-PCI bridge driver (the previous driver just handled
Host-PCI bridges) that is a PCI driver that is a subclass of the generic
PCI-PCI bridge driver. It overrides probe, attach, read_ivar, and
pci_route_interrupt.
- The probe routine only succeeds if our parent is an ACPI PCI bus which
we test for by seeing if we can read our ACPI_HANDLE as an ivar.
- The attach routine saves a copy of our handle and calls the new
acpi_pcib_attach_common() function described below.
- The read_ivar routine handles normal PCI-PCI bridge ivars and adds an
ivar to return the ACPI_HANDLE of the bus this bridge represents.
- The route_interrupt routine fetches the _PRT (PCI Interrupt Routing
Table) from the bridge device's softc and passes it off to
acpi_pcib_route_interrupt() to route the interrupt.
- Split the old ACPI Host-PCI bridge driver into two pieces. Part of
the attach routine and most of the route_interrupt routine remain in
acpi_pcib.c and are shared by both ACPI PCI bridge drivers.
- The attach routine verifies the PCI bridge is present, reads in
the _PRT for the bridge, and attaches the child PCI bus.
- The route_interrupt routine uses the passed in _PRT to route a PCI
interrupt.
The rest of the driver is the ACPI Host-PCI bridge specific bits that
live in acpi_pcib_acpi.c.
- We no longer duplicate pcib_maxslots but use it directly.
- The driver now uses the pcib devclass instead of its own devclass.
This means that PCI busses are now only children of pcib devices.
- Allow the ACPI_HANDLE for the child PCI bus to be read as an ivar
of the child bus.
- Fetch the _PRT for routing PCI interrupts directly from our softc
instead of walking the devclass to find ourself and then fetch our
own softc.
With this change and the new ACPI PCI bus driver, ACPI can now properly
route interrupts for devices behind PCI-PCI bridges. That is, the
Itanium2 with like 10 PCI busses can now boot ok and route all the PCI
interrupts. Hopefully this will also fix problems people are having with
CardBus bridges behind PCI-PCI bridges not properly routing interrupts
when ACPI is used.
Tested on: i386, ia64
driver. This driver overrides the probe, attach, and read_ivar methods.
If the parent bridge is an ACPI PCI bridge, then the probe routine will
match, otherwise it will fail. It tests this by seeing if it can get
the ACPI_HANDLE ivar from the bridge device.
In the attach routine, it uses pci_add_children() to add all the child
devices (but with a slightly larger ivar so it can store ACPI_HANDLE's
for child devices) and then walks through the ACPI namespace below the
bus device to cache ACPI_HANDLE's for all child devices present in the
namespace. It does this by comparing the pci slot and function to the
address encoded in _ADR of the devices in the ACPI namespace.
The read_ivar routine passes most requests off to pci_read_ivar()
and adds a new request so that the ACPI_HANDLE for a child device can
be read.
To add proper power support the power methods can be overridden as well,
but that is not currently implemented. Also, there are cases where a
device may show in the ACPI namespace as a PCI device that the PCI probe
does not find. Currently such devices are ignored.
Tested on: i386, ia64
OOP speak, you would mark these as 'protected' members. Specifically:
- Make the pcib_softc struct public so it can be used by subclasses.
- Make pcib_{read,write}_ivar(), pcib_alloc_resource(), pcib_maxslots(),
and pcib_{read,write}_config() globals that can be used by subclasses.
- Make the pcib devclass a global variable.
- Move most of the pcib_attach() function into a global
pcib_attach_common() function that can be called by the attach routines
of subclasses.
Tested on: i386, alpha, sparc64, ia64
- Make the pci devclass a global variable.
- Add child devices in pci_attach() instead of pci_probe(). Change
pci_probe() to just check for a valid bus number from the associated
bridge and return -1000 if successful. This allows subclasses of the
PCI bus driver to override the generic driver.
- Move the code to load the vendor data into its own public function.
Really though, doing this at attach is just plain wrong. This should
really be done in the module load routine instead. As a side effect,
the 'busno' variable in pci_attach() is now no longer static (minor
bug that was harmless so far.)
- Change pci_add_children() to take an extra argument that is the size of
the device info structure passed to pci_read_device() and make it public
so subclasses of the PCI bus can call it in their attach routines.
- Move the bits to attach a probed PCI child to a PCI bus into a global
pci_add_child() function. This will allow subclasses that can detect
a PCI device not found in the normal PCI probe to add those devices in
their own attach routine. (I have seen this in the ACPI tree on my
laptop for example.) As a side effect, change the static function
pci_add_resources() to get the busno, slot, and func from the passed
in dinfo structure instead of requiring them as function arguments.
Tested on: i386, alpha, ia64, sparc64
LNK device (interrupt source provider sort of) is present before using it,
but the code actually tested the status (_STA) of the PCI bridge device

This is required for some Thinkpad (and maybe VAIO) machines to wake
the system up from sleep.
Currently partially implemented, more complete implementation will come later.
pci support. This really needs to be fixed properly some day, but judging
by the fact that the nopci case hasn't compiled for quite a while, there
does not seem to be much urgency.

This driver actually works slightly better on -stable than on -current
(the system locks on detach on -current), so it should be MFC'd somewhat
sooner.
This driver currently points out a difficulty in the sound device framework.
The PCM unregister routine is allowed to refuse the detach if the device is
in use. In the case of a USB device, however, this unregistration is much more
mandatory in nature, since the device is *actually* gone when this call is
made. The sound subsystem really should not refuse an unregistration and
should take its own steps to reject further I/O. As a result, if you detach
a USB sound device while it is in use, you can expect a panic shortly
thereafter.
This device cannot currently record audio. Some routines are unwritten as
of yet in uaudio.c to support recording.
This device hangs my -current box on detach. I don't know why. This does
not happen on my -stable machine.

in the .h file. Make it static __inline to make sure that it doesn't
wind up defined in any files.
Also, fix a typo that said null_do_attach instead of null_do_probe.

The value we use is still questionable for 440BX chipsets.
- When flushing the TLB just toggle the bit in question instead of writing
a magic value that could trash other unrelated bits.
because the previous interface handle gets freed when the config
number is set. This fixes a problem where memory could be accessed
after it was freed when the interface was ifconfig'd up.

one out of a block cipher. This has 2 advantages:
1) The code is _much_ simpler
2) We aren't committing our security to one algorithm (much as we
may think we trust AES).
While I'm here, make an explicit reseed do a slow reseed instead
of a fast; this is in line with what the original paper suggested.
- always reinitialize the rx descriptors, even if the mbuf is kept.
This should fix the hangs on ifconfig that were observed
- on an rx overflow, reinitialize the descriptor so that the interface
will not hang
- correct some bus_dmamap_sync() calls
- correct some debug messages
- some minor nits
o Assert that the page queues lock is held in vm_page_unwire().
o Make vm_page_lock_queues() and vm_page_unlock_queues() visible
to kernel loadable modules.
This code does not imply that SBus cards work yet. They hang for me.
But I can't netboot the latest snapshot on my ultra1e, and things
hang at bus_setup_intr time.
Since I'm offline for a while, I thought I'd toss this in in case somebody
else who has a bit better luck wants to fart around with it. Please try
and wait until I get back to check things in.
