This package contains the PCI Utilities, version 2.1.9. Copyright (c) 1997--2001 Martin Mares All files in this package can be freely distributed and used according to the terms of the GNU General Public License, either version 2 or (at your opinion) any newer version. This is the same distribution policy as for the Linux kernel itself -- see /usr/src/linux/COPYING for details. 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 also has an experimental support for 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. If you want, subscribe to linux-pci@atrey.karlin.mff.cuni.cz (send "subscribe linux-pci" to majordomo@atrey.karlin.mff.cuni.cz). Release notes about new versions will be send to the list and problems with the Linux PCI support will be probably discussed there, too. You also might want to look at the pciutils web page containing release notes and other news: http://atrey.karlin.mff.cuni.cz/~mj/pciutils.html . If you're missing any PCI ID's, please look at the home page of the Linux PCI ID Repository at http://pciids.sourceforge.net/ and download an updated pci.ids file first. If the current version doesn't contain your devices, please send us an update either using the Web interface of the Repository or just mail a unified diff against the latest pci.ids to pci-ids@ucw.cz. There also exists a utility called PowerTweak which is able to fine tune parameters of many chipsets much better than the Bridge Optimization code in Linux kernel (already removed in 2.3.x). See http://powertweak.sf.net/ for more information. Have fun Martin
