lspci - list all PCI devices

Xwindow 설정시 현재 설치 되어 있는
그래픽 카드의 슬롯 번호라던가 종류등을 알아 내기 위해사용 한다.

위에는 현재 서버 노트북의 lspci 결과이다.

이녀석이 어떤때 쓰이냐면은..

/etc/X11/xorg.conf 에서

Section "Device"     Identifier    "Radeon-Cloned"     Driver        "ati"     BusID        "PCI:1:0:0" EndSection [출처 : http://rtr.ca/dell_i9300/xorg.conf]

이런식으로 사용되고, PCI:1:0:0은 대개 AGP를 의미한다고 한다.

Synopsis

lspci [options]

Description

lspci is a utility for displaying information about all PCI buses in the system and all devices connected to them.

By default, it shows a brief list of devices. Use the options described below to request either a more verbose output or output intended for parsing by other programs.

If you are going to report bugs in PCI device drivers or in lspci itself, please include output of "lspci -vvx" or even better "lspci -vvxxx" (however, see below for possible caveats).

Some parts of the output, especially in the highly verbose modes, is probably intelligible only to experienced PCI hackers. For the exact definitions of the fields, please consult either the PCI specifications or the header.h and /usr/include/linux/pci.h include files.

Access to some parts of the PCI configuration space is restricted to root on many operating systems, so the features of lspci available to normal users are limited. However, lspci tries its best to display as much as available and mark all other information with <access denied> text.
