Created attachment 107155 [details] [review] patch The patch is here and sent to mailing list. However I'm closing the bug anyway since the powertop behaviour described isn't true. I just tested my patch with latest powertop v2.6.1 and it still shows RC6p and RC6pp as 0%.

That's exactly the behavior that I said current powertop has; thus, this change will not break existing versions of powertop. I'm proposing this change because then *new* versions of powertop can stop displaying these fields entirely. Josh, please notice that even though both Sandybridge and Ivybdrige support RC6p and RC6pp, by default we don't ever enable RC6pp on any platform, and we only enable RC6p on Ivybridge. So we're still going to have the "Why isn't my system getting into a deeper sleep state?" questions for the next decades. The advantage is that only people with SNB and IVB will be asking this. Since we're probably still going to have the questions, setting up a webpage with an answer and an IRC bot to parse questions and provide the FAQ URL would be a better bug fix. Still, let's work to get Rodrigo's patch merged. Patch merged upstream. Thanks for the request/suggestion. commit bb530a44ceaec228bdf7329e303875d2cc82c115 Author: Rodrigo Vivi <rodrigo.vivi@intel.com> Date: Tue Oct 7 07:06:50 2014 -0700 drm/i915: Do not export RC6p and RC6pp if they don't exist |
