# lsgpu(1)

List and inspect GPUs by scanning the PCI bus, DRM, and sysfs

## Name

lsgpu - List and inspect GPUs by scanning the PCI bus, DRM, and sysfs

## SYNOPSIS

**lsgpu** \[*OPTIONS*\]

## DESCRIPTION

**lsgpu** is part of the **igt-gpu-tools** suite, and it is designed to assist in GPU enumeration and debugging. **lsgpu**  is a command-line tool for listing and inspecting GPUs available on the system. It scans the PCI bus, DRM subsystem, and sysfs to gather information about detected GPU devices and their properties.

By default, **lsgpu** displays a list of GPUs along with basic details. The tool supports additional options to print detailed properties and sysfs attributes, apply filters to select specific devices, and verify access permissions to GPU nodes.

Filtering can be performed using the -d or --device option, allowing users to match GPUs based on vendor, PCI attributes, or other criteria. When a filter is applied, only the first matching device is displayed.

Additionally, **lsgpu** attempts to open the corresponding DRM device nodes (/dev/dri/cardX, /dev/dri/renderDX) to check for access permissions. It follows the IGT variable search order for selecting the target device:

- 1\.

  The **--device** option, if provided

- 2\.

  The **IGT\_DEVICE** environment variable, if set

- 3\.

  The **.igtrc** configuration file (Common::Device setting), if neither of the above is specified

## OPTIONS

- **-h, --help**

  Show help text.

- **-n, --numeric**

  Print vendor/device as hex

- **-c, --codename**

  Print codename instead pretty device name

- **-s, --print-simple**

  Print simple (legacy) device details

- **-p, --print-details**

  Print devices with details

- **-P, --pci-scan**

  Print PCI GPU devices

- **-v, --list-vendors**

  List recognized vendors

- **-l, --list-filter-types**

  List registered device filters types

- **-d,***--device* **\<filter\>**

  Apply a device filter (e.g. 'pci:vendor=Intel,device=discrete,card=0'). Can be used multiple times.

- **-V, --version**

  Print version information and exit

### Default print mode options

These options are only valid when using the default printout mode:

- **--drm**

  Default: Print DRM filters for each device

- **--sysfs**

  Print sysfs filters for each device

- **--pci**

  Print PCI filters for each device
