- 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.

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
doing the routing, not the actual LNK device. Fix it to check the status
of the LNK device.
pmap_zero_page() and pmap_zero_page_area() were modified to accept
a struct vm_page * instead of a physical address, vm_page_zero_fill()
and vm_page_zero_fill_area() have served no purpose.
Attempt to determine what function of AUX_OUT is: "True line level
out", "Headphone out", or "4-Channel out" and frig OSS mixer label

Addresses problem raised by Randy Bush on -multimedia of not being
able to hear audio on ich2 m/b which was eventually found to be
because the mixer monitor value was 0. On this h/w the label
"monitor" should now be presented as the marginally more intuitive
"ogain".
We now also read configuration information for the SCSI cards- this allows
us to try and say what the speed settings now are.
Start, but not yet complete, the process of reorgs && #defines so that we

but since pc hardware only allows one AT-style keyboard controller, this
doesn't seem particularly urgent. (I do not know what the old sunriver
remote keyboard/mouse/vga cards do, that might be an exception).
little more than a place holder, because nothing actually counted the
number of 'sc' units to compare it against NSC. A bit more work here
is needed so that the scaling of SC_MAX_HISTORY_SIZE and extra_history_size
goes up when more sc units are added. But, it does not appear that we can
have more than one console yet, so it does not seem particularly urgent.

load f/w images > 0x7fff words), set ISP_FW_ATTR_SCCLUN. We explicitly
don't believe we can find attributes if f/w is < 1.17.0, so we have to
set SCCLUN for the 1.15.37 f/w we're using manually- otherwise every
target will replicate itself across all 16 supported luns for non-SCCLUN
f/w.
Correctly set things up for 23XX and either fast posting or ZIO. The
23XX, it turns out, does not support RIO. If you put a non-zero value
in xfwoptions, this will disable fast posting. If you put ICBXOPT_ZIO
in xfwoptions, then the 23XX will do interrupt delays but post to the
response queue- apparently QLogic *now* believes that reading multiple
handles from registers is less of a win than writing (and delaying)
multiple 64 byte responses to the response queue.
At the end of taking a a good f/w crash dump, send the ISPASYNC_FW_DUMPED
event to the outer layers (who can then do things like wake a user
daemon to *fetch* the crash image, etc.).

accept an 'active_cred' argument reflecting the credential of the thread
initiating the ioctl operation.
- Change fo_ioctl() to accept active_cred; change consumers of the
fo_ioctl() interface to generally pass active_cred from td->td_ucred.
- In fifofs, initialize filetmp.f_cred to ap->a_cred so that the
invocations of soo_ioctl() are provided access to the calling f_cred.
Pass ap->a_td->td_ucred as the active_cred, but note that this is
required because we don't yet distinguish file_cred and active_cred
in invoking VOP's.
- Update kqueue_ioctl() for its new argument.
- Update pipe_ioctl() for its new argument, pass active_cred rather
than td_ucred to MAC for authorization.
- Update soo_ioctl() for its new argument.
- Update vn_ioctl() for its new argument, use active_cred rather than
td->td_ucred to authorize VOP_IOCTL() and the associated VOP_GETATTR().

This is an architecture that present a thing message passing interface
to the OS. You can query as to how many ports and what kind are attached
and enable them and so on.
A less grand view is that this is just another way to package SCSI (SPI or
FC) and FC-IP into a one-driver interface set.
This driver support the following hardware:
LSI FC909: Single channel, 1Gbps, Fibre Channel (FC-SCSI only)
LSI FC929: Dual Channel, 1-2Gbps, Fibre Channel (FC-SCSI only)
LSI 53c1020: Single Channel, Ultra4 (320M) (Untested)
LSI 53c1030: Dual Channel, Ultra4 (320M)
Currently it's in fair shape, but expect a lot of changes over the
next few weeks as it stabilizes.

The driver is mostly from some folks from Jeff Roberson's company- I've
been slowly migrating it to broader support that I it came to me as.
The hardware used in developing support came from:
FC909: LSI-Logic, Advansys (now Connetix)
FC929: LSI-Logic
53c1030: Antares Microsystems (they make a very fine board!)

is that some cards built around fm801 chip have the same device ID, only
have radio tuner onboard, but no sound capabilities. Therefore, with such
card inserted and `device pcm' in kernel the user has a big problem, as
the fm801 driver effectively hangs the machine when trying to initialise
nonexistent ac97 codecs (it does 500 retries with 1 second interval!).
