- The PCI Utilities package contains a library for portable access to
- PCI bus configuration registers and several utilities based on this
- library.
- Currently, pciutils work on all versions of Linux and they also have
- somewhat experimental support for OpenBSD, FreeBSD, NetBSD, AIX, GNU
- Hurd and Solaris/x86. It should be very easy to add support for other
- systems as well (volunteers wanted; if you want to try that, I'll be
- very glad to see the patches and include them in the next version).
- The utilities include: (See manual pages for more details)
- - lspci: displays detailed information about all PCI buses and
- devices.
- - setpci: allows to read from and write to PCI device configuration
- registers. For example, you can adjust the latency timers with it.
- CAUTION: There is a couple of dangerous points and caveats, please
- read the manual page first!
- - update-pciids: download the current version of the pci.ids file.
- On OpenBSD you need to set sysctl machdep.allowaperture=2 in
- /etc/sysctl.conf, and run lspci and setpci as root.
