GPU-LS(1)

NAME
gpu-ls - display details about gpu compatible GPU cards

SYNOPSIS
gpu-ls [--short]
gpu-ls [--help | --about]
gpu-ls [--clinfo] [--no_fan] [--ppm] [--pstates]

CONFIGURATION
In order to get maximum capability of these utilities, you should be running with a kernel that provides support of the GPUs you have installed. If using AMD GPUs, installing the latest amdgpu driver package or the latest ROCm release, may provide additional capabilities. If you have Nvidia GPUs installed, nvidia-smi must also be installed in order for the utility reading of the cards to be possible. Writing to GPUs is currently only possible for AMD GPUs, and only with compatible cards and with the the AMD ppfeaturemask set to 0xfffd7fff. This can be accomplished by adding amdgpu.ppfeaturemask=0xfffd7fff to the GRUB_CMDLINE_LINUX_DEFAULT value in /etc/default/grub and executing sudo update-grub.

DESCRIPTION
gpu-ls displays most relevant parameters for installed and compatible GPUs. The default behavior is to list relevant base parameters by GPU.

OPTIONS

--about
    Will display details about gpu-ls.

--clinfo
    If the clinfo package is installed, openCL details will be included in the output for each compatible GPU.

--no_fan
    Will exclude fan information from the display. Useful with water cooled GPUs.

--short
    Will display short list of key descriptive parameters for each installed GPU.

--table
    Will display table of basic GPU parameters.

--ppm
    Will display descriptions of available power performance modes.

--pstates
    Will display P-state table for system and memory clocks.

--debug
    Will output additional useful debug/troubleshooting details to a log file.

-h, --help
    Display help text and exit.

EXAMPLES
gpu-ls
This will display the basic parameters for all compatible GPUs. These include device ID, GPU frequency/voltage control type, decoded device ID, card model, short card model, display card model, card number, card path, PCIe ID, driver, vBIOS version, HWmon path, current power, power cap, power cap range, fan enable, fan PWM mode, current fan PWM, current fan speed, fan target speed, fan speed range, fan PWM range, current temp, critical temp, current VddGF, Vddc range, current GPU loading, memory details, link speed, link width, current Sclk p-state, current Sclk frequency, Sclk range, current Mclk p-state, current Mclk frequency, Mclk range, power performance mode, and power force performance level.

gpu-ls --short
This will produce a short list of key descriptive parameters for each installed GPU.

gpu-ls --clinfo
In addition to the basic parameters, openCL parameters are also displayed for each compatible GPU. This option is dependent on the installation of clinfo.

gpu-ls --ppm
Instead of the basic parameters, a table of power/performance modes is displayed.

gpu-ls --pstates
Instead of the basic parameters, a table of power states or curve points is displayed.

FILES

/usr/share/misc/pci.ids
    The system list of all known PCI ID's (vendors, devices, classes and subclasses). It can be updated with the update-pciids command.

/sys/class/drm/card*/device/pp_od_clk_voltage
    Special driver file for each AMD GPU required by some rickslab-gpu-utils.

/etc/default/grub
    The grub defaults file where amdgpu.ppfeaturemask needs to be set.

BUGS
Known to not work well with Fiji ProDuo cards and will issue warning messages for Fiji Nano cards. Please report any additional bugs/issues at https://github.com/Ricks-Lab/amdgpu-utils
