+.TH INTEL_FREQUENCY: "1" "January 2015" "intel_gpu_frequency" "User Commands"
+.SH NAME
+intel_gpu_frequency: \- manual page for intel_gpu_frequency
+.SH SYNOPSIS
+.B intel_gpu_frequency
+[\fI\,-e\/\fR] [\fI\,--min | --max\/\fR] [\fI\,-g (min|max|efficient)\/\fR] [\fI\,-s frequency_mhz\/\fR]
+.SH DESCRIPTION
+\&A program to manipulate Intel GPU frequencies. Intel GPUs
+will automatically 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 attempt 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.
+.SH OPTIONS

+.TP
+\fB\-c\fR, \fB\-\-custom\fR
+Set a min, or max frequency "min=X | max=Y"
+.TP
+\fB\-m\fR  \fB\-\-max\fR
