gpu-mon - continuously update a table with the state of all compatible GPUs

gpu-mon [--help | --about]
gpu-mon [--gui] [--no_fan] [--plot] [--ltz] [--sleep N] [--debug] [--pdebug]

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.

gpu-mon will continuously display the current state of all compatible GPUs. The default behavior is to update a text based table in the current window until Ctrl-C is pressed. Command line options can alter this behaviour allowing the use of GUI, modifying update interval, excluding fans, writing to a log, selecting UTC or local time zone, and engaging a graphical display of real-time trends of relevant parameters.

Will display details about gpu-mon.
The table of relevant parameters will be updated in a Gtk window instead of a text table in the terminal window.
Write all mon data to a logfile. The real-time display will indicate that logging is enabled and will show the filename used.
Use local time zone instead of UTC for displays and logging.
Will exclude fan information from the display. Useful with water cooled GPUs.
Will enable debug output for the gpu-plot plotting utility.
Open and write to, gpu-plot, the gpu-util plotting utility.
Specifies N, the number of seconds to sleep between updates.
Will output additional useful debug/troubleshooting details to a log file.
Display help text and exit. 

gpu-mon --sleep 5 --log

Will display a continuously updating table of GPU operating parameters updating with an interval of 5 sec. All parameters will be written to a logfile which will be indicated in the table. The displayed parameters include GPU model, GPU and memory load percentage, power, power cap, energy consumption, temperature, voltage (not available for NV), fan speed, Sclk frequency/p-state, Mclk frequency/pstate, and performance mode. Updating of the table will continue until ctrl-c is pressed.

gpu-mon --gui


Will open a new Gtk window and display basic parameters updated with the default interval.

gpu-mon --plot


Will open 2 new Gtk windows. One will display the basic parameters and the second will display a continuously updating plot of these parameters. It is suggested that this method be used if both displays are desired, instead of executing both gpu-mon and gpu-plot as the later will result in twice the reads of GPU data.

/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.

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
