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.
Note
Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.
Package Information
pciutils Dependencies
Recommended
cURL-8.5.0, Wget-1.21.4, or Lynx-2.8.9rel.1 (for the update-pciids script to function correctly).
Installation of PCI Utils
Install PCI Utils by running the following commands:
make PREFIX=/usr \
SHAREDIR=/usr/share/hwdata \
SHARED=yes
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-8.5.0, Lynx-2.8.9rel.1, or Wget-1.21.4 which are used to download the most current file, and then replace the existing file in /usr/share/hwdata
.
You should update the /usr/share/hwdata/pci.ids
file periodically. If you've installed Fcron-3.2.1 and completed the section on periodic jobs, execute the following commands, as the root
user, to create a weekly cron job:
cat > /etc/cron.weekly/update-pciids.sh << "EOF" &&
#!/bin/bash
/usr/sbin/update-pciids
EOF
chmod 754 /etc/cron.weekly/update-pciids.sh
