Introduction to PCI Utilities

The PCI Utilities package is 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-7.1 platform.

Installation of PCI Utilities

Install PCI Utilities by running the following commands: 

make PREFIX=/usr MANDIR=/usr/share/man \
     ZLIB=no SHARED=yes PCI_COMPRESSED_IDS=0 all

This package does not come with a test suite.

Now, as the root user: 

make PREFIX=/usr MANDIR=/usr/share/man \
     ZLIB=no SHARED=yes PCI_COMPRESSED_IDS=0 \
     install install-lib

Command Explanations

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

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

PCI_COMPRESSED_IDS=0: This parameter ensures that compression won't be used when updating pci.ids.

Configuring PCI Utilities

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-2.20 script or program to find cURL-7.25.0, Wget-1.13.4 or Lynx-2.8.8dev.10 which are used to download the most current file, and then replace the existing file in /usr/share.

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