The PCI Utilities

What's that?

The PCI Utilities are a collection of programs for inspecting and manipulating configuration of PCI devices, all based on a common portable library libpci which offers access to the PCI configuration space on a variety of operating systems.


Thanks to, there are online versions of man pages of the utilities available. Please note that they take some time to update after new pciutils are released.

Supported systems

The library (and therefore all the utilities) works on the following operating systems:

However, not everything is supported on all systems. Some back-ends are read-only, some access the I/O ports directly, which need not work reliably. The only back-end which has all the features is Linux with a recent kernel.


The latest release of pciutils is version 3.12.0 (2024-04-05).

You can download it from the following servers. Please note that we provide only sources not compiled binaries for any system (with an occasional exception of Windows).

Releases are signed with the PGP key of Martin Mareš.

Git repositories

Development of the pciutils happens in the following Git repositories:


The PCI Utilities also contain a list of known vendors and devices. It is used for displaying vendor/device names instead of the ID numbers reported by the devices themselves. The list is maintained separately by the PCI ID Database project. Daily snapshots are available there and also mirrored at GitHub.

If lspci doesn't recognize some device in your machine and you know what the device is, please submit an update to the database.


You can ask questions and report bugs on the linux-pci mailing list running on Vger, but please Cc the author ( Announcements about new versions are also sent to the list.
