Introduction to PCI Utils

The PCI Utils package contains a set of programs for listing PCI devices, inspecting their status and setting their configuration registers.

This package is known to build and work properly using an LFS-8.2 platform.

Installation of PCI Utils

Install PCI Utils by running the following commands:

make PREFIX=/usr                \
     SHAREDIR=/usr/share/hwdata \

This package does not come with a test suite.

Now, as the root user:

make PREFIX=/usr                \
     SHAREDIR=/usr/share/hwdata \
     SHARED=yes                 \
     install install-lib        &&

chmod -v 755 /usr/lib/libpci.so

Command Explanations

SHARED=yes: This parameter enables building of the shared library instead of the static one.

ZLIB=no: This option prevents compression of the pci.ids file.

Configuring PCI Utils

The pci.ids data file is constantly being updated. To get a current version of this file, run update-pciids as the root user. This program requires the Which-2.21 script or program to find cURL-7.58.0, Lynx-2.8.8rel.2 or Wget-1.19.4 which are used to download the most current file, and then replace the existing file in /usr/share/hwdata.

You may wish to add an entry to root's (or any other user who has write privilege to /usr/share/hwdata) crontab to automatically update the pci.ids file periodically.


Installed Programs: lspci, setpci, and update-pciids
Installed Library: libpci.so
Installed Directory: /usr/include/pci and /usr/share/hwdata
