Using -v results in a more detailed listing:
$ lspci -v [...] 01:00.0 \ VGA compatible controller: Matrox Graphics, Inc. MGA G550 AGP (rev 01) \ (prog-if 00 [VGA]) Subsystem: Matrox Graphics, Inc. Millennium G550 Dual Head DDR 32Mb Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at d8000000 (32-bit, prefetchable) [size=32M] Memory at da000000 (32-bit, non-prefetchable) [size=16K] Memory at db000000 (32-bit, non-prefetchable) [size=8M] Expansion ROM at <unassigned> [disabled] [size=128K] Capabilities: <available only to root>
Information about device name resolution is obtained from file /usr/share/pci.ids. PCI IDs not listed in this file are marked “Unknown device”.
The parameter -vv produces all the information that could be queried by the program. To view the pure numeric values, you should use the parameter -n.
