lspci stands for list pci. Think of this command as 'ls' + 'pci'.
Rogers place edmonton casino restaurants buffet. This will display information about all the PCI bus in your server.
To check the total free memory amount, physically used and swap memory, you will use the free command. The free command is also used to display the information about buffers that are used by the kernel and specifications of the RAM of your system. Type the following command to check the system's memory: $ free -m -h. Top command is mainly used to display dynamic real-time view of a running system especially the Linux processes or threads currently being managed by the Linux kernel. But it also displays system summary information, including RAM memory and swap free and used size. To exit from top program, press Ctrl + c, or just q.
Apart from displaying information about the bus, it will also display information about all the hardware devices that are connected to your PCI and PCIe bus.
For example, it will display information about Ethernet cards, RAID controllers, Video cards, etc.
lspci utility is part of the pciutils package.
If you don't have pciutilis, install it on your system as shown below.
1. Default Usage
By default it will display all the device information as shown below. The first field is the slot information in this format: [domain:]bus:device.function
In this example, since all the domain are 0, lspci will not display the domain.
Note: In all the examples below, we'll be showing only partial output by picking couple of devices from the above list.
2. Dump PCI Info in Different Format
If you want to pass the output of the lspci command to a shell script, you may want to use -m option (or -mm option) as shown below.
This option is also helpful when you want to view the subsystem information. For example, for the RAID controller, the default output just says that is is using LSI Logic RAID controller. But, the following output displays the subsystem, which is DELL PERC H700 Integrated RAID controller system.
3. Output in Tree Format
The -t option will display the output in tree format with information about bus, and how devices are connected to those buses as shown below. The output will be only using the numerical ids.

4. Detailed Device Information
If you want to look into details of a particular device, use -v to get more information. This will display information about all the devices. The output of this command will be very long, and you need to scroll down and view the appropriate section.
For additional level for verbosity, you can use -vv or -vvv.
In the following example, I've given output of only the RAID controller device.
5. Display Device Codes in the Output
If you want to display the PCI vendor code, and the device code only as the numbers, use -n option. This will not lookup the PCI file to get the corresponding values for the numbers.
If you want to display both the description and the number, use the option -nn as shown below.
6. Lookup a Specific Device
When you know the slot number in the domain:bus:slot.func format, you can query for a particular device as shown below. What's the closest casino to lake geneva wisconsin. In the following example, we didn't specify the domain number, as it is 0, which can be left out.
When you know the device number in the vendor:device format, you can query for a particular device as shown below.
If you know only either the vendor id, or the device id, you can omit the other id. For example, both the following command will return the same output as the above.
7. Display Kernel Drivers
This is very helpful when you like to know the name of the kernel module that will be handling the operations of a particular device. Please note that this option will work only on Kernel 2.6 version and above.
