The PCI Utilities




The PCI Utilities

What's that?

The PCI Utilities package contains a library for portable access to PCI bus
configuration space and several utilities based on this library. Current
version works only on Linux and FreeBSD, but it can be easily extended to work
on other systems as well.

The utilities include: (See manual pages for more details)

lspci
displays detailed information about all PCI busses and devices
in the system, replacing the original /proc/pci interface.
setpci
allows to read from and write to PCI device configuration
registers. For example, you can adjust the latency timers with it.


The library (and therefore all the utilities) can access PCI registers
either via the /proc/bus/pci interface present since Linux 2.1.82 or
via direct hardware access (to be used with older kernels and also for
hardware diagnostics). It's also capable of reading and interpreting
register dumps printed by `lspci -x'.
Unfortunately, there is no documentation
on how to use the library yet, so if you want to play with it, just ask
me for whatever you want.

To compile the package, just run "make". To install it, "make install".

If you have any bug reports or suggestions, send them to the author.

You can ask questions and report bugs on the linux-pci
mailing list. Ask majordomo@atrey.karlin.mff.cuni.cz
to subscribe. Announcements about new versions are also sent there.

Where can I get it?

The latest release can be downloaded from:

atrey.karlin.mff.cuni.cz
ftp.kernel.org (expect a few hours delay)
metalab.unc.edu (expect a few days delay)


You can find the latest updates to the pci.ids file (the list
of all known vendor, device, subsystem and class ID's) in the PCI
ID Repository.

If you dare to try a development version, look at our Alpha directory, but keep in mind that these versions tend to be everything else than stable and bug-free.
