pcictl(8) -- a program for frobbing the PCI bus, and also an example
of how to use libpci.

Currently has "list" (list devices within a PCI domain) and "dump" (dump
PCI configuration header for a device) sub-commands.

Use .Sy, not .Em, for bold-faced WARNING of impending doom.

Underline and, worse, italic aren't as good at catching the eye.

apply the previous typo in another place as well.

Sort sections. Formatting nitpicks. Fix typo.

add some examples: "pcictl pci0 list" and "pcictl pci0 list -N".

Sternly advise against `pcictl read/write'. Use .Cm, not .Nm, while here.

add -N option to print the driver name as returned by pci_drvname(3).

Use more appropriate macro for command line command argument.

Add quoting for minus, for PostScript output.

Today I learned that 'pcictl pci0 list -b -1' lists devices on all busses.

New sentence, new line.

Add "list -n" to print ID and class numerical, instead of resolving to strings:

miyu% pcictl /dev/pci1 list
001:00:0: ATI Technologies Rage Fury MAXX AGP 4x (TMDS) (VGA display)
miyu% pcictl /dev/pci1 list -n
001:00:0: 0x50461002 (0x3000000)

fix typo.

By poppular demand, don't wildcard "bus" on the "list" command
by default.

introduce a better pci_drvname() and PCI_IOC_DRVNAME as pciio_drvnameonbus()
and PCI_IOC_DRVNAMEONBUS. the new ones also take a (autoconf) PCI bus
number, which allows lookups for any device on any pci bus node. use this
in pcictl which current reports the wrong values sometimes.

up next: use these in libpciaccess.

avoid very long loop when you run pcictl on a PCI bus which has no devices on it.

Update for new pci_devinfo(3) signature.

Homogenize usage messages: make the 'usage' word all lowercase, as this seems
to be the most common practice in our tree.

sweep of errx/warnx, remove unnecessary trailing \n

Don't abuse opendisk(3) to open PCI bus devices which are no disks. This
fixes PR bin/14468 by Valeriy E. Ushakov.

use strtol instead of atoi to catch non numeric values

By poppular demand, don't wildcard "bus" on the "list" command
by default.

Fix missing : in a getopt() string.
