From cc7387f17ce5750fc640355d94ed60b6936c2d7b Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Tue, 1 Mar 2016 12:57:48 +0200 Subject: man: rewrite manual pages in reStructuredText 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.

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 + +REPORTING BUGS +============== + +Report bugs to https://bugs.freedesktop.org. -- cgit v1.2.3
