| 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 The documentation is out of date | |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. | |

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. | |

| 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. | |
