How to identify a device > PCI


How to "identify" the PCI-like devices (AGP, PCI-Express, CardBus, Express Card, etc) that are connected to you computer.

Many people simply use lspci, which is available on every Debian system, to list the device on their computer. hardinfo is available to install and use with GTK based desktops such as GNOME, MATE or Xfce. users can install and use the method. kinfocenter is available in KDE Plasma Desktop.

PCI-id

PCI devices are identified by a pair of hexadecimal numbers. 1014:003E for example.

  • The 4 first hexadecimal digits are the Vendor ID (1014 = IBM)
  • The 4 last hexadecimal digits are the Device ID (003e = 16/4 Token ring)

There is also some sub-vendor-id, sub-vendor-id (to identify the computer/vendor implementation), PCI function and class, see the references section for more information.

Some of the devices (device-ids) handled by Debian are listed in the DeviceDatabase/PCI page.

lspci

lspci (from the pciutils package) is the standard tool to query the devices connected to any PCI compatible bus.

{i} discover uses its own files: /lib/discover/pci-busclass.xml, /lib/discover/pci-device.xml, /lib/discover/pci-vendor.xml

Manual

/proc/bus/pci/devices

If lspci isn't available (!), you can display the content of /proc/bus/pci/devices to list vendor and device IDs.

$ cat /proc/bus/pci/devices 

/sys/bus/pci

If lspci isn't available (!), you can browse /sys/bus/pci (assuming sysfs is mounted on /sys). The Linux kernel sysfs PCI documentation (also available in the linux-doc packages) gives details about the files in /sys/bus/pci.
