-Beware, this is a preliminary test version! Anything might not work!
-
-Some more things I intend to merge before the 2.2.0 release:
-
- o pcimodules and possibly other Linux module related stuff
- o Linux sysfs support
- o Support for PCI domains (at least partially; needed for sysfs)
- o New ID's from the pciids project
- o Cross-compilation support

1. What's that?
~~~~~~~~~~~~~~~
The PCI Utilities package contains a library for portable access to PCI bus
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, NetBSD 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

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.
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
