基础用法

由于访问权限，普通用户运行 lspci 时显示的信息可能会受限，因此可以使用 sudo 运行命令，系统会给出完整的信息图。

直接运行 lspci 命令会列出 PCI 总线及其连接的设备，下图是在我的虚拟机 PC 上的演示样例。

NAME
       lspci - list all PCI devices

SYNOPSIS
       lspci [options]

DESCRIPTION
       lspci is a utility(实用工具) for displaying information about PCI buses in the system and devices connected to them.

       By  default, it shows a brief list(简要列表) of devices. Use the options described below to request either a more verbose(更详细的) output or output intended(预期的) 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(警告)).

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

       Access to some parts of the PCI configuration space is restricted(受限制的) 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.

OPTIONS

基本显示模式

   Basic display modes
       -m     Dump PCI device data in a backward-compatible(向后兼容) machine readable form.  See below for details.

       -mm    Dump PCI device data in a machine readable form for easy parsing by scripts.  See below for details.

       -t     Show a tree-like diagram(简图) containing all buses, bridges, devices and connections between them.

显示模式

   Display options
       -v     Be verbose and display detailed information about all devices.

       -vv    Be very verbose and display more details. This level includes everything deemed(被认为) useful.

       -vvv   Be even more verbose and display everything we are able to parse, even if it doesn't look interesting at all (e.g.,  undefined  memory regions).

       -k     Show kernel drivers handling each device and also kernel modules capable of handling it.  Turned on by default when -v is given in the normal mode of output.  (Currently works only on Linux with kernel 2.6 or newer.)

       -x     Show hexadecimal dump of the standard part of the configuration space (the first 64 bytes or 128 bytes for CardBus bridges).

       -xxx   Show hexadecimal dump of the whole PCI configuration space. It is available only to root as several PCI devices crash when you try  to read some parts of the config space (this behavior probably doesn't violate the PCI standard, but it's at least very stupid). However, such devices are rare, so you needn't worry much.

       -xxxx  Show hexadecimal dump of the extended (4096-byte) PCI configuration space available on PCI-X 2.0 and PCI Express buses.

       -b     Bus-centric view. Show all IRQ numbers and addresses as seen by the cards on the PCI bus instead of as seen by the kernel.

       -D     Always show PCI domain numbers. By default, lspci suppresses them on machines which have only domain 0.

       -P     Identify PCI devices by path through each bridge, instead of by bus number.

       -PP    Identify PCI devices by path through each bridge, showing the bus number as well as the device number.

用于控制将 ID 解析为名称的选项

   Options to control resolving ID's to names
       -n     Show PCI vendor and device codes as numbers instead of looking them up in the PCI ID list.

       -nn    Show PCI vendor and device codes as both numbers and names.

       -q     Use DNS to query the central PCI ID database if a device is not found in the local pci.ids file. If the DNS query succeeds, the result is  cached  in ~/.pciids-cache and it is recognized in subsequent runs even if -q is not given any more. Please use this switch inside automated scripts only with caution to avoid overloading the database servers.

       -qq    Same as -q, but the local cache is reset.

       -Q     Query the central database even for entries which are recognized locally.  Use this if you suspect that the displayed entry is wrong.

设备选择选项

   Options for selection of devices
       -s [[[[<domain>]:]<bus>]:][<device>][.[<func>]]
              Show only devices in the specified domain (in case your machine has several host bridges, they can either share a  common  bus  number space  or  each of them can address a PCI domain of its own; domains are numbered from 0 to ffff), bus (0 to ff), device (0 to 1f) and function (0 to 7).  Each component of the device address can be omitted or set to "*", both meaning "any value". All numbers are hexa‐ decimal.   E.g.,  "0:" means all devices on bus 0, "0" means all functions of device 0 on any bus, "0.3" selects third function of device 0 on all buses and ".4" shows only the fourth function of each device.

       -d [<vendor>]:[<device>][:<class>]
              Show only devices with specified vendor, device and class ID. The ID's are given in hexadecimal and may be omitted or  given  as  "*", both meaning "any value".

其他选项

   Other options
       -i <file>
              Use <file> as the PCI ID list instead of /usr/share/misc/pci.ids.

       -p <file>
              Use  <file>  as the map of PCI ID's handled by kernel modules. By default, lspci uses /lib/modules/kernel_version/modules.pcimap.  Ap‐
              plies only to Linux systems with recent enough module tools.

       -M     Invoke bus mapping mode which performs a thorough scan of all PCI devices, including those behind misconfigured bridges, etc. This option  gives  meaningful results only with a direct hardware access mode, which usually requires root privileges.  Please note that thebus mapper only scans PCI domain 0.

       --version
              Shows lspci version. This option should be used stand-alone.

PCI 访问选项

   PCI access options
       The PCI utilities use the PCI library to talk to PCI devices (see pcilib(7) for details). You can use the following options to influence  its
       behavior:

       -A <method>
              The  library supports a variety of methods to access the PCI hardware.  By default, it uses the first access method available, but you can use this option to override this decision. See -A help for a list of available methods and their descriptions.

       -O <param>=<value>
              The behavior of the library is controlled by several named parameters.  This option allows one to set the value of any of the  parame‐ ters. Use -O help for a list of known parameters and their default values.

       -H1    Use direct hardware access via Intel configuration mechanism 1.  (This is a shorthand for -A intel-conf1.)

       -H2    Use direct hardware access via Intel configuration mechanism 2.  (This is a shorthand for -A intel-conf2.)

       -F <file>
              Instead  of accessing real hardware, read the list of devices and values of their configuration registers from the given file produced by an earlier run of lspci -x.  This is very useful for analysis of user-supplied bug reports, because you can  display  the  hardware configuration in any way you want without disturbing the user with requests for more dumps.

       -G     Increase debug level of the library.

MACHINE READABLE OUTPUT
       If  you  intend to process the output of lspci automatically, please use one of the machine-readable output formats (-m, -vm, -vmm) described in this section. All other formats are likely to change between versions of lspci.

       All numbers are always printed in hexadecimal. If you want to process numeric ID's instead of names, please add the -n switch.

   Simple format (-m)
       In the simple format, each device is described on a single line, which is formatted as parameters suitable for passing  to  a  shell  script, i.e.,  values separated by whitespaces, quoted and escaped if necessary.  Some of the arguments are positional: slot, class, vendor name, de‐ vice name, subsystem vendor name and subsystem name (the last two are empty if the device has no subsystem); the remaining arguments are  op‐
       tion-like:

       -rrev  Revision number.

       -pprogif
              Programming interface.

       The  relative order of positional arguments and options is undefined.  New options can be added in future versions, but they will always have a single argument not separated from the option by any spaces, so they can be easily ignored if not recognized.

   Verbose format (-vmm)
       The verbose output is a sequence of records separated by blank lines.  Each record describes a single device by a  sequence  of  lines,  each line containing a single `tag: value' pair. The tag and the value are separated by a single tab character.  Neither the records nor the lines within a record are in any particular order.  Tags are case-sensitive.

参数定义

       The following tags are defined:

       Slot   The name of the slot where the device resides ([domain:]bus:device.function).  This tag is always the first in a record.

       Class  Name of the class.

       Vendor Name of the vendor.

       Device Name of the device.

       SVendor
              Name of the subsystem vendor (optional).

       SDevice
              Name of the subsystem (optional).

       PhySlot
              The physical slot where the device resides (optional, Linux only).

       Rev    Revision number (optional).

       ProgIf Programming interface (optional).

       Driver Kernel driver currently handling the device (optional, Linux only).

       Module Kernel module reporting that it is capable of handling the device (optional, Linux only). Multiple lines with this tag can occur.

       NUMANode
              NUMA node this device is connected to (optional, Linux only).

       New tags can be added in future versions, so you should silently ignore any tags you don't recognize.

   Backward-compatible verbose format (-vm)
       In this mode, lspci tries to be perfectly compatible with its old versions.  It's almost the same as the regular verbose format, but the  De‐ vice  tag  is  used  for  both the slot and the device name, so it occurs twice in a single record. Please avoid using this format in any new code.

FILES
       /usr/share/misc/pci.ids
              A list of all known PCI ID's (vendors, devices, classes and subclasses). Maintained at https://pci-ids.ucw.cz/, use the  update-pciids utility to download the most recent version.

       /usr/share/misc/pci.ids.gz
              If lspci is compiled with support for compression, this file is tried before pci.ids.

       ~/.pciids-cache
              All ID's found in the DNS query mode are cached in this file.

BUGS
       Sometimes, lspci is not able to decode the configuration registers completely.  This usually happens when not enough documentation was available to the authors.  In such cases, it at least prints the <?> mark to signal that there is potentially something more to say. If  you  know the details, patches will be of course welcome.

       Access to the extended configuration space is currently supported only by the linux_sysfs back-end.
