I've changed the defaults to what has been proposed in this bug report. Why 50% was chosen, I really don't have an answer. But thanks for reporting the bug. I took time to monitor it today, and the improvements are good, and there is no negative power impact. I don't intend another point release immediately. So, until the next release, please change the values. Exact git commit is: commit 07457235f45630b7b5b0091eed7774fe7fb39147 Author: Ritesh Raj Sarraf <[email protected]> Date: Thu Apr 7 19:05:42 2016 +0530 Fix defaults for Intel P State Driver Thanks: George Caswell and Matthew Gabeler-Lee Closes: #814578 The LMT P State module's history shows the ONBATT default value of 50. I have no history on why that was chosen. But reading up the docs, and looking at the feedback from reporters (thanks), this seems to be wrong. Intel P State driver is self sufficient in scaling in/out the frequency and voltage based on the state of the machine. There isn't a need to do much from sysfs, for the default cases.
