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-7.64.0, Lynx-2.8.9rel.1 or Wget-1.20.1 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. Execute the following commands, as the root user, to create a systemd timer to update it weekly on Sundays at 2:30 A.M. (local time):

cat > /lib/systemd/system/update-pciids.service << "EOF" &&
[Unit]
Description=Update pci.ids file
Documentation=man:update-pciids(8)
DefaultDependencies=no
After=local-fs.target network-online.target
Before=shutdown.target

[Service]

RemainAfterExit=yes
ExecStart=/usr/sbin/update-pciids

Description=Update pci.ids file weekly

[Timer]
OnCalendar=Sun 02:30:00
Persistent=true
