INTEL_GPU_FREQUENCY(1) General Commands Manual INTEL_GPU_FREQUENCY(1) NAME intel_gpu_frequency - Manipulate Intel GPU frequencies SYNOPSIS intel_gpu_frequency [OPTIONS] DESCRIPTION A program to manipulate Intel GPU frequencies. Intel GPUs will automati- cally throttle the frequencies based on system demands, up when needed, down when not. This tool should only be used for debugging performance problems, or trying to get a stable frequency while benchmarking. Intel GPUs only accept specific frequencies. The tool may, or may not at- tempt to adjust requests to the proper frequency if they aren't correct. This may lead to non-obvious failures when setting frequency. Multiples of 50MHz is usually a safe bet. OPTIONS -e Lock frequency to the most efficient frequency. -g, --get Get all the current frequency settings. -s FREQUENCY, --set=FREQUENCY Lock frequency to an absolute value (MHz). -c, --custom Set a min, or max frequency "min=X | max=Y". -m, --max Lock frequency to max frequency. -i, --min Lock frequency to min (never a good idea, DEBUG ONLY). -d, --defaults Return the system to hardware defaults. -h, --help Show help. -v, --version Show version. EXAMPLES intel_gpu_frequency -gmin,cur Get the current and minimum frequency. intel_gpu_frequency -s 400 Lock frequency to 400Mhz. intel_gpu_frequency -c max=750 Set the max frequency to 750MHz REPORTING BUGS Report bugs to <https://bugs.freedesktop.org> .
