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

Lspci -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.)

Lspci -s
-s [[[[
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 hexadecimal. 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.

Lspci -vmm
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.
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).
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.

Lspci -d
-d [
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".
