1. What's that?
configuration registers and several utilities based on this library.
Currently, pciutils work on all versions of Linux and they also have somewhat
-experimental support for FreeBSD and AIX. It should be very easy to add support
-for other systems as well (volunteers wanted; if you want to try that, please
-send the patches to me, so that I can include them in the next version).
+experimental support for FreeBSD, NetBSD, AIX, GNU Hurd and Solaris/x86.
+It should be very easy to add support for other systems as well (volunteers
+wanted; if you want to try that, I'll be very glad to see the patches and
+include them in the next version).
The utilities include: (See manual pages for more details)
- - lspci: displays detailed information about all PCI busses and devices.
+ - lspci: displays detailed information about all PCI buses and devices.
- setpci: allows to read from and write to PCI device configuration
registers. For example, you can adjust the latency timers with it.
CAUTION: There is a couple of dangerous points and caveats, please read
the manual page first!
+ - update-pciids: download the current version of the pci.ids file.

2. Compiling and (un)installing
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If you are missing names for any of your devices or you just want to stay
on the bleeding edge, download the most recent pci.ids file from
-http://pciids.sf.net/. You can try "make update-ids" to accomplish that
-automatically (requires wget and bzip2).
+http://pciids.sf.net/ (e.g., by running the update-ids utility).
If your devices still appear as unknown, please send us their ID's and
names, the detailed instructions for submissions are listed on the
4. Available access methods
~~~~~~~~~~~~~~~~~~~~~~~~~~~
The library (and therefore all the utilities) know a variety of methods for
-accessing the PCI registers. Here is a list of them:
+accessing the PCI registers. Here is a list of them, sorted by autodetection
+priority:
/proc/bus/pci on all Linux systems since kernel 2.1.82.
- direct port access on all Linux systems with i386, to be used when
- /proc/bus/pci is unavailable or you want to scan
- the bus manually when hunting kernel bugs.
- dumps reading of dumps produced by `lspci -x'.
- lsdev + odmget used on AIX
+ /sys/bus/pci on all Linux systems since kernel 2.5.xx.
+ direct port access on i386 systems running Linux, GNU Hurd or Solaris/x86;
+ available only to root, useful if no other access
+ method is available or you want to hunt kernel bugs
/dev/pci used on FreeBSD
+ lsdev + odmget used on AIX
+ libpci used on NetBSD
+ dumps reading of dumps produced by `lspci -x'
+ (this one is not autodetected)

There also exists a utility called PowerTweak which is able to fine tune
parameters of many chipsets much better than the Bridge Optimization code
