Tim Gore	20d6e0f41b	tools/intel_gpu_frequency: remove use of getsubopt ... getsubopt is not available in android. The "get" option doesn't really need sub-options, just display all the current frequency settings (as per discussion with Ben Widawsky) Ben v2: Remove the -geff example in the header Fixed another typo for the --set while there (found by Dave Gordon) Signed-off-by: Tim Gore <tim.gore@intel.com> Reviewed-by: Ben Widawsky <ben@bwidawsk.net>	2015-01-16 10:23:34 -08:00
Ben Widawsky	5fb26d1469	intel_gpu_frequency: A tool to manipulate Intel GPU frequency ... WARNING: very minimally tested In general you should not need this tool. Its primary purpose is for benchmarking, and for debugging performance issues. For many kernel releases now sysfs has supported reading and writing the GPU frequency. Therefore, this tool provides no new functionality. What it does provide is an easy to package (for distros) tool that handles the most common scenarios. v2: Get rid of -f from the usage message (Jordan) Add space before [-s (Jordan) Add a -c/--custom example (Jordan) Add a setting for resetting to hardware default (Ken) Replicate examples in commit message in the source code. (me) v3: Its not It's (me) Add --help/-h to usage Add Version + man page Rename tool to intel_gpu_frequency, from intel_frequency Remove "sudo" from the examples Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Reviewed-by: Jordan Justen <jordan.l.justen@intel.com> Cc: Kenneth Graunke <kenneth@whitecape.org> Here are some sample usages: $ intel_gpu_frequency --get=cur,min,max,eff cur: 200 MHz min: 200 MHz RP1: 200 MHz max: 1200 MHz $ intel_gpu_frequency -g cur: 200 MHz min: 200 MHz RP1: 200 MHz max: 1200 MHz $ intel_gpu_frequency -geff RP1: 200 MHz $ intel_gpu_frequency --set min=300 $ intel_gpu_frequency --get min cur: 300 MHz min: 300 MHz RP1: 200 MHz max: 1200 MHz $ intel_gpu_frequency --custom max=900 $ intel_gpu_frequency --get max cur: 300 MHz min: 300 MHz RP1: 200 MHz max: 900 MHz $ intel_gpu_frequency --max $ intel_gpu_frequency -g cur: 1200 MHz min: 1200 MHz RP1: 200 MHz max: 1200 MHz $ intel_gpu_frequency -e $ intel_gpu_frequency -g cur: 200 MHz min: 200 MHz RP1: 200 MHz max: 200 MHz $ intel_gpu_frequency --max $ intel_gpu_frequency -g cur: 1200 MHz min: 1200 MHz RP1: 200 MHz max: 1200 MHz $ intel_gpu_frequency --min $ intel_gpu_frequency -g cur: 200 MHz min: 200 MHz RP1: 200 MHz max: 200 MHz	2015-01-12 15:58:21 -08:00
