937a5e2c20 Simplify chkattached(). The PCIOCATTACHED ioctl only needs the pi_sel
field populated, it ignores the rest of the 'pci_sel' structure.

da1e0915c5 - Add a new ioctl to /dev/pci to fetch details on an individual BAR of a
device.  The details include the current value of the BAR (including all
  the flag bits and the current base address), its length, and whether or not
  it is enabled.  Since this operation is not invasive, non-root users are
  allowed to use it (unlike manual config register access which requires
  root).  The intention is that userland apps (such as Xorg) will use this
  interface rather than dangerously frobbing the BARs from userland to
  obtain this information.
- Add a new sub-mode to the 'list' mode of pciconf.  The -b flag when used
  with -l will now list all the active BARs for each device.

8818afb711 Make selector parsing accept the dot "." as an alternative selector
with identical meaning as the colon ":". This is to support a syntax
that is more similar to a PCI device specification in the device hints
file. The selector is not fully compatible with the specification in
the hints file, since entries in that file use a different prefix,
which needs to be added to the getsel() routine, if full support of
that syntax is found to be desirable.

d23a84a0a8 Restore compatibility with version before introduction of PCI domains.
PCI selectors with 2 or 3 elements behave exactly as before (i.e. the
domain is 0 and in the 2 element case, the function is also 0).
The form with 4 selector elements works as in the previous revision
and provides the PCI domain number as the left-most selector element.

This change allows old scripts (which used the 2 or 3 selector element
formats) to be kept. Without this patch, the 3 element form was parsed
as starting with a domain number (and the function was assumed to be 0),
with this patch, the domain is assumed to be 0 (and the last value is
used as the function number).

The man page is updated to describe the new selector semantics.

55aaf894e8 Make the PCI code aware of PCI domains (aka PCI segments) so we can
support machines having multiple independently numbered PCI domains
and don't support reenumeration without ambiguity amongst the
devices as seen by the OS and represented by PCI location strings.
This includes introducing a function pci_find_dbsf(9) which works
like pci_find_bsf(9) but additionally takes a domain number argument
and limiting pci_find_bsf(9) to only search devices in domain 0 (the
only domain in single-domain systems). Bge(4) and ofw_pcibus(4) are
changed to use pci_find_dbsf(9) instead of pci_find_bsf(9) in order
to no longer report false positives when searching for siblings and
dupe devices in the same domain respectively.
Along with this change the sole host-PCI bridge driver converted to
actually make use of PCI domain support is uninorth(4), the others
continue to use domain 0 only for now and need to be converted as
appropriate later on.
Note that this means that the format of the location strings as used
by pciconf(8) has been changed and that consumers of <sys/pciio.h>
potentially need to be recompiled.

8866f04eb1 - Teach pciconf(8) to list the PCI capabilities supported by each device
via a new -c flag to be used with -l.  Some simple parsing code is
  present for the following capabilities: Power Management, AGP, VPD,
  MSI, PCI-X, HyperTransport, Vendor-specific, EHCI Debug Port, PCI-PCI
  bridge subvendor ID, PCI-express, and MSI-X.
- Fix a few warnings in pciconf.c.
- Update some cruft in pciconf(8):
  - PCI 2.1 is no longer a revolutionary standard, and subvendor ID's are
    fairly common at this point, so reflect that.
  - Header type 2 is used for PCI-CardBus bridges.
  - Describe the -v option for -l after completing the basic -l description
    instead of disrupting the flow in the middle.

7df76a1312 Use larger buffers to read lines from the vendor list.
Trim trailing whitespace and comments before parsing, and skip empty lines.
Skip subvendor / subdevice entries (which start with two tab characters).
Change the scanf() format string to match any amount and type of whitespace

6c72866dff Only a read-only file descriptor is required to implement list_devs()
and list_verbose(), so don't open /dev/pci read-write.  This allows
pciconf -l[v] to work for non-root users, assuming the securelevel is
0 or -1.

64ae346b52 [ repository copy of sys/pci/pci_ioctl.h to sys/sys/pciio.h happened in the
background ]

Rename sys/pci/pci_ioctl.h to sys/sys/pciio.h to make it easier for
userland programs to use this interface.  Reformat the file, and add a
BSD-style copyright to it.

Add a new man page for pci(4).  The PCIOCGETCONF, PCIOCREAD, and PCIOCWRITE
ioctls are documented, but the PCIOCATTACHED ioctl is not documented
because it is not implemented.

Change includes of <pci/pci_ioctl.h> to <sys/pciio.h> or remove them
altogether.  In many cases, pci_ioctl.h was unused.

7f054c59a5 Modify pciconf(8) so that it will print out PCI devices that have no driver
configured in the kernel.  It gives them a device name of "none" and
monotonically incrementing unit numbers.  (starting at 0)  Before, pciconf
would just skip over unconfigured devices.  (unconfigured devices can be
detected because they have a null string for a device name)

Update the man page to reflect the new pciconf output.  Unfortunately, this
causes the sample 'pciconf -l' output lines to wrap, but I'm not sure what
to do about that really.

If anyone presents a reasonable case for printing out something other than
"none1" for unconfigured devices, I'm willing to listen.
