En sistemes Debian, l'ordre lspci es proporcionada pel paquet pciutils.
$ whereis lspci lspci: /usr/bin/lspci /usr/share/man/man8/lspci.8.gz $ dpkg -S /usr/bin/lspci pciutils: /usr/bin/lspci
L'ordre lspci mostra informació sobre el bus PCI i altres dispositius del sistema.
Un exemple de la comanda sense opcions:
$ lspci 00:00.0 Host bridge: nVidia Corporation nForce3 250Gb Host Bridge (rev a1) 00:01.0 ISA bridge: nVidia Corporation nForce3 250Gb LPC Bridge (rev a2) 00:01.1 SMBus: nVidia Corporation nForce 250Gb PCI System Management (rev a1) 00:02.0 USB Controller: nVidia Corporation CK8S USB Controller (rev a1) 00:02.1 USB Controller: nVidia Corporation CK8S USB Controller (rev a1) 00:02.2 USB Controller: nVidia Corporation nForce3 EHCI USB 2.0 Controller (rev a2) 00:06.0 Multimedia audio controller: nVidia Corporation nForce3 250Gb AC'97 Audio Controller (rev a1) 00:08.0 IDE interface: nVidia Corporation CK8S Parallel ATA Controller (v2.5) (rev a2) 00:0a.0 IDE interface: nVidia Corporation CK8S Serial ATA Controller (v2.5) (rev a2) 00:0b.0 PCI bridge: nVidia Corporation nForce3 250Gb AGP Host to PCI Bridge (rev a2) 00:0e.0 PCI bridge: nVidia Corporation nForce3 250Gb PCI-to-PCI Bridge (rev a2) 00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] HyperTransport Technology Configuration 00:18.1 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Address Map 00:18.2 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] DRAM Controller 00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control 01:00.0 VGA compatible controller: ATI Technologies Inc RV280 [Radeon 9200 PRO] (rev 01) 02:07.0 FireWire (IEEE 1394): VIA Technologies, Inc.

En sistemes Debian, aquesta comanda es proporcionada pel paquet pciutils.
Podem obtenir informació més detallada podem utilitzar el paràmetre verbose (-v)
$ lspci -v | more 00:00.0 Host bridge: Intel Corporation 82Q35 Express DRAM Controller (rev 02) Subsystem: Hewlett-Packard Company Device 2819 Flags: bus master, fast devsel, latency 0 Capabilities: <access denied> Kernel driver in use: agpgart-intel Kernel modules: intel-agp 00:02.0 VGA compatible controller: Intel Corporation 82Q35 Express Integrated Graphics Controller (rev 02) Subsystem: Hewlett-Packard Company Device 2819 Flags: bus master, fast devsel, latency 0, IRQ 2300 Memory at f0100000 (32-bit, non-prefetchable) [size=512K] I/O ports at 1230 [size=8] Memory at e0000000 (32-bit, prefetchable) [size=256M] Memory at f0000000 (32-bit, non-prefetchable) [size=1M] Capabilities: <access denied>
Com podeu observar, és convenient utilitzar la comanda more per paginar els resultats de la comanda.
Observeu la línia:
Capabilities: <access denied>
Això ens indica que certa informació només és accessible al superusuari:
Acacha Wiki$ sudo lspci -v | more
...
00:02.0 VGA compatible controller: Intel Corporation 82Q35 Express Integrated Graphics Controller (rev 02)
...
Capabilities: [90] Message Signalled Interrupts: Mask- 64bit- Queue=0/0 Enable+ Capabilities: [d0] Power Management version 2
Es poden afegir encara més paràmetres -v (doble o triple) per tal d'obtenir una sortida encara més completa. Combinat amb la opció -x (fa un volcat hexadecimal de l'espai de configuració) podem obtenir sortides molt completes que sovint només són útils quan es fan coses molt avançades relacionades amb el maquinari:
$ lspci -vvvxxxx
Com en moltes altres comandes, hi ha la opció -n (numèric) que en comptes de mostrar els noms del dispositiu i del fabricant. Per exemple:
$ lspci -n 00:00.0 0600: 8086:29b0 (rev 02) 00:02.0 0300: 8086:29b2 (rev 02) ...
Si ho compareu amb:
$ lspci 00:00.0 Host bridge: Intel Corporation 82Q35 Express DRAM Controller (rev 02) 00:02.0 VGA compatible controller: Intel Corporation 82Q35 Express Integrated Graphics Controller (rev 02)
Tenim doncs la següent assignació codi-->dispositiu/fabricant
Es pot mostrar combinat amb:
$ lspci -nn 00:00.0 Host bridge [0600]: Intel Corporation 82Q35 Express DRAM Controller [8086:29b0] (rev 02) 00:02.0 VGA compatible controller [0300]: Intel Corporation 82Q35 Express Integrated Graphics Controller [8086:29b2] (rev 02) 00:03.0 Communication controller [0780]: Intel Corporation 82Q35 Express MEI Controller [8086:29b4] (rev 02)
La conversió de codi a nom es fa mitjançant el fitxer:
/usr/share/misc/pci.ids
El qual, en sistemes Debian, també proporciona el paquet pciutils. Es pot utilitzar un altre fitxer amb la opció -i.
Es pot mostrar en forma d'arbre la sortida amb la opció -t:
$ lspci -tv

Finalment hi ha una opció avançada que només pot fer el superusuari que és realitzar un scanner:
$ sudo lspci -M
A vegades pot revelar dispositius amagats darreta d'una configuració incorrecte.
Aquesta comanda utilitza la carpeta fitxer:
/proc/bus/pci
Per obtenir informació sobre els dispositius PCI.
Podeu consultar el manual:
$ man lspci
O online a:
http://linux.die.net/man/8/lspci
NOTA: Tot i que l'ordre es digui lspci, també mostra informació dels dispositius AGP i posteriors com pci-e
Primer cal identificar quin és el dispositiu AGP amb:
$ lspci -nn | grep VGA 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc RV280 [Radeon 9200 PRO] [1002:5960] (rev 01)
en negreta està l'identificador. Ara podeu consultar tota la informació sobre aquest dispositiu amb:
