Add a new -e flag to pciconf(8)'s list mode to display PCI error details.
Currently this dumps the status of any error bits in the PCI status register
and PCI-express device status register. It also lists any errors indicated
by version 1 of PCI-express Advanced Error Reporting (AER).

- 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.

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.

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.

- Bump document date.
- Kill whitespace at EOL.
- Add missing markup bit.

- 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.

Update to improve handling of verbose PCI vendor/device information.

- Read the database from /usr/share/misc (or wherever else we're pointed)
rather than compiling it in.
- Decode the class/subclass fields if requested.
- Print things in a slightly longer but more readable format.

mdoc(7) police: do not split author names in the AUTHORS section.

mdoc(7) police: use the new features of the Nm macro.

Add support for decoding the PCI vendor and device ID registers. Add a
database of about 1400 vendors and 2700 devices courtesy of
www.yourvote.com/pci. We still need to add some more, but this is a good
start.

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

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.

Sync usage string with man page.

Revert $FreeBSD$ to $Id$
