  12 BIG FAT WARNING: This is an ALPHA version. The documentation is out of date
  13                  and the same holds for spec files and even for this README.
  14                  And, of course, you should expect this release to contain BUGS.
  15
  16 WHY ALPHA?       I've split the real PCI access primitives from the rest
  17                  of the code and created libpci, which supports not only
  18                  /proc/bus/pci, but also direct hardware access and reading
  19                  of configuration space dumps and it's intended to work
  20                  on all Linux versions and even on non-Linux systems, making
  21                  creation of portable programs communicating with PCI devices
  22                  possible.

  26    The Linux PCI Utilities contain various utilities for dealing with the PCI
  27 bus in Linux:
  28
  29         - lspci: displays detailed information about all PCI busses and devices
  30           in the system, replacing the original /proc/pci interface.
  31
  32         - setpci: allows to read from and write to PCI device configuration
  33           registers. For example, you can adjust the latency timers with it.
  34
  35    See manual pages for more details.
  36
  37    To compile the package, just run "make". To install it, "make install".
  38
  39    You need kernel 2.1.82 or newer to use all functions of this package.
  40 For older kernels, only direct hardware access is supported and you must
  41 be root to use it.
  42
  43    If you have any bug reports or suggestions, send them to the author.

  46 "subscribe linux-pci Your Full Name" to listproc@atrey.karlin.mff.cuni.cz).
  47 Release notes about new versions will be send to the list and problems with
  48 the Linux PCI support will be probably discussed there, too.
