intel_reg.rst was the first man page written in reStructuredText. Follow suit with the rest of the man pages. Add a generated defs.rst include file for definitions such as intel-gpu-tools version. This replaces the MAN_SUBSTS sed script substitutions from xorg-macros for old man pages. Signed-off-by: Jani Nikula <jani.nikula@intel.com>

SYNOPSIS
|
|
========
|
|
|
|
**intel_gpu_frequency** [*OPTIONS*]
|
|
|
|
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.
|
|
|
|
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
