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
