linux中lspci是一个用来显示系统中所有PCI总线设备或连接到该总线上的所有设备的工具,比如查看网卡、存储等信息。   参数   -v 使得 lspci 以冗余模式显示所有设备的详细信息。   -vv 使得 lspci 以过冗余模式显示更详细的信息 (事实上是 PCI 设备能给出的所有东西)。这些数据的确切意义没有在此手册页中解释,如果你想知道更多,请参照 /usr/include/linux/pci.h 或者 PCI 规范。   -n 以数字形式显示 PCI 生产厂商和设备号,而不是在 PCI ID 数据库中查找它们。   -x 以十六进制显示 PCI 配置空间 (configuration space) 的前64个字节映像 (标准头部信息)。此参数对调试驱动和 lspci 本身很有用。   -xxx 以十六进制显示所有 PCI 配置空间的映像。此选项只有 root 可用,并且很多 PCI 设备在你试图读取配置空间的未定义部分时会崩溃 (此操作可能不违反PCI标准,但是它至少非常愚蠢)。   -b 以总线为中心进行查看。显示所有 IRQ 号和记忆体地址,就像 PCI 总线上的卡看到的一样,而不是核心看到的内容。   -t 以树形方式显示包含所有总线、桥、设备和它们的连接的图表。   -s [[]:][][.[]] 仅显示指定总线、插槽上的设备或设备上的功能块信息。设备地址的任何部分都可以忽略,或以「*」代替 (意味著所有值)。所有数字都是十六进制。例如:「0:」指的是在0号总线上的所有设备;「0」指的是在任意总线上0号设备的所有功能块;「0.3」选择 了所有总线上0号设备的第三个功能块;「.4」则是只列出每一设备上的第四个功能块。   -d []:[] 只显示指定生产厂商和设备 ID 的设备。 这两个 ID 都以十六进制表示,可以忽略或者以「*」代替 (意味著所有值)。     -i使用作为 PCI ID 数据库而不是使用预设的 /usr/share/hwdata/pci.ids。   -m 以机器可读的方式转储 PCI 设备数据 (支持两种模式:普通和冗余),便於稿本解析。   -M 使用总线映射模式,这种模式对总线进行全面地扫描以查明总线上的所有设备,包括配置错误的桥之后的设备。请注意,此操作只应在调试时使 用,并可能造成系统崩溃 (只在设备有错误的时候,但是不幸的是它们存在),此命令只有 root 可以使用。同时,在不直接接触硬体的 PCI 访问模式中使用 -M 参数没有意义,因为显示的结果 (排除 lspci 中的 bug 的影响) 与普通的列表模式相同。   –version 显示 lspci 的版本。这个选项应当单独使用。   -P使用 linux 2.1 风格的配置,直接访问目录而非 /proc/bus/pci 目录。(只能在linux 2.1或以上版本中使用)   -H1 通过 Intel 架构 1 来实现直接硬体访问。(只能用於 i386 及其相容机)   -H2 通过Intel 架构2来实现直接硬体访问。警告:此模式只能寻址任何总线上的前16个设备,并且在很多情况下相当不可靠。(只能用於 i386 及其相容机)   -S 使用 PCI 系统调用访问。(只能用於 Alpha 和 Ultra-Sparc 上的 Linux)     -F从所给的包含 lspci -x 命令输出的档案中相关信息。这在分析使用者提交的错误报告时很有用,因为你可以用任何方式来显示硬体配置信息而无需为了更多信息打扰使用者。(可用於所有系统)   -G 增加库的调试等级。(可用於所有系统)   实例   lspci -t [BDF]:显示指定BDF号的设备信息。   lspci -m/-mm:以一种机器可读的格式来显示pci设备信息。   # lspci -s ff:13.1

Memory Controller 0 – Target Address/Thermal/RAS” -r03 “Intel Corporation” “Broadwell Memory Controller 0 – Target Address/Thermal/RAS”   lspci -t:以树的形式显示pci设备信息。   lspci -v/-vv/-vvv:显示详细的pci设备信息,v越多,越详细,当然,上限3个。   lspci -x/-xxx/-xxxx:-x以16进制信息显示pci配置空间;-xxx显示部分读配置空间会crash的设备;-xxxx显示PCI-x2.0或者PCI-e总线扩展的配置空间。   lspci -b:以总线的角度来显示所有的IRQ和地址。根据我的观察,大部分信息和不带参数时显示一致,除了SR-IOV设备分配出的Virtual Function设备。如下示例:物理网卡PF(physical function )显示一直 ,但VF(virtual function )显示却不同。     # lspci -b -s 0a:00.1; lspci -b -s 0a:10.0 0a:00.1

#显示配置空间的标准部分的十六进制转储 -xxx Show hex-dump of the whole config space (dangerous; root only) #显示整个配置空间的十六进制转储(危险;只有root) -xxxx Show hex-dump of the 4096-byte extended config space (root only) #显示4096字节扩展配置空间的十六进制转储(仅限root用户) -b Bus-centric view (addresses and IRQ’s as seen by the bus) #以总线为中心的视图(巴士所看到的地址和IRQ) -D Always show domain numbers #始终显示域名编号 Resolving of device ID’s to names: -n Show numeric ID’s#将设备ID解析为名称: -nn Show both textual and numeric ID’s (names & numbers) #显示文本和数字ID(姓名和号码) -q Query the PCI ID database for unknown ID’s via DNS #通过DNS查询未知ID的PCI ID数据库 -sigusoft As above, but re-query locally cached entries #如上所述,但重新查询本地缓存条目 -Q Query the PCI ID database for all ID’s via DNS #通过DNS查询所有ID的PCI ID数据库 Selection of devices: -s [[[[<domain>]:]<bus>]:][<slot>][.[<func>]] Show only devices in selected slots #仅显示选定插槽中的设备 -d [<vendor>]:[<device>][:<class>] Show only devices with specified ID’s #仅显示具有指定ID的设备 Other options: -i <file> Use specified ID database instead of /usr/share/hwdata/pci.ids #使用指定的ID数据库而不是/usr/share/hwdata/pci.ids -p <file> Look up kernel modules in a given file instead of default modules.pcimap #查找给定文件中的内核模块而不是默认的modules.pcimap -M Enable `bus mapping’ mode (dangerous; root only) #启用`总线映射’模式(危险;只有root) PCI access options: -A <method> Use the specified PCI access method (see `-A help’ for a list) #使用指定的PCI访问方法(请参阅`-A help’列表) -O <par>=<val> Set PCI access parameter (see `-O help’ for a list) #设置PCI访问参数(请参阅“-O帮助”列表) -G Enable PCI access debugging #启用PCI访问调试 -H <mode> Use direct hardware access (<mode> = 1 or 2) #使用直接硬件访问(<mode> = 1或2) -F <file> Read PCI configuration dump from a given file #从给定文件读取PCI配置转储 简单的几个例子:(grep指令:https://blog.csdn.net/rong_toa/article/details/) #查看显卡信息 $ lspci | grep -i vga 00:0f.0 VGA compatible controller: VMware SVGA II Adapter #只显示制定槽中的设备 $ lspci -s 00:0f.0 00:0f.0 VGA compatible controller: VMware SVGA II Adapter #用机器可读的形式输出 $ lspci -mm -s 00:0f.0 00:0f.0 “VGA compatible controller” “VMware” “SVGA II Adapter” “VMware” “SVGA II Adapter” $ lspci -Q -s 00:0f.0 00:0f.0 VGA compatible controller: VMware SVGA II Adapter $ lspci -D -s 00:0f.0 0000:00:0f.0 VGA compatible controller: VMware SVGA II Adapter 查看详细信息: $ lspci -v -s 00:0f.0 00:0f.0 VGA compatible controller: VMware SVGA II Adapter (prog-if 00 [VGA controller]) Subsystem: VMware SVGA II Adapter Flags: bus master, medium devsel, latency 64, IRQ 16 I/O ports at 1070 [size=16] Memory at e (32-bit, prefetchable) [size=128M] Memory at fe000000 (32-bit, non-prefetchable) [size=8M] [virtual] Expansion ROM at c0000000 [disabled] [size=32K] Capabilities: <access denied> Kernel driver in use: vmwgfx
