  12    The PCI Utilities package contains a library for portable access to PCI bus
  13 configuration space and several utilities based on this library. Current
  14 version works only on Linux and also has an experimental support for FreeBSD,
  15 but it can be easily extended to work on other systems as well.
  16
  17    The utilities include:  (See manual pages for more details)
  18
  19         - lspci: displays detailed information about all PCI busses and devices
  20           in the system, replacing the original /proc/pci interface.
  21
  22         - setpci: allows to read from and write to PCI device configuration
  23           registers. For example, you can adjust the latency timers with it.
  24
  25    The library (and therefore all the utilities) can access PCI registers
  26 either via the /proc/bus/pci interface present since Linux 2.1.82 or
  27 via direct hardware access (to be used with older kernels and also for
  28 hardware diagnostics). It's also capable of reading and interpreting
  29 register dumps printed by `lspci -x'. Unfortunately, there is no documentation
  30 on how to use the library yet, so if you want to play with it, just ask
  31 me for whatever you want.
  32
  33    To compile the package, just run "make". To install it, "make install".
  34
  35    If you have any bug reports or suggestions, send them to the author.
  36
  37    If you want, subscribe to linux-pci@atrey.karlin.mff.cuni.cz (send
  38 "subscribe linux-pci" to majordomo@atrey.karlin.mff.cuni.cz).
  39 Release notes about new versions will be send to the list and problems with
  40 the Linux PCI support will be probably discussed there, too.
  41
  42    You also might want to look at the pciutils web page containing release
  43 notes and other news: http://atrey.karlin.mff.cuni.cz/~mj/pciutils.html .
  44
  45    If you're missing any PCI ID's, please look at the home page of the Linux
  46 PCI ID Repository at http://pciids.sourceforge.net/ and download an updated
  47 pci.ids file first. If the current version doesn't contain your devices,
  48 please send us an update either using the Web interface of the Repository
  49 or just mail a unified diff against the latest pci.ids to pci-ids@ucw.cz.
  50
  51    There also exists a utility called PowerTweak which is able to fine tune
  52 parameters of many chipsets much better than the Bridge Optimization code
  53 in Linux kernel (already removed in 2.3.x). See http://powertweak.sf.net/
  54 for more information.
