Subject: [PATCH V3 00/13] cpufreq: governors: Fix ABBA lockups
Date: Mon, 8 Feb 2016 17:09:14 +0530 [thread overview]
Message-ID: <cover.1454931188.git.viresh.kumar@linaro.org> (raw)
Hi Rafael,
Things look much much better now. I have rebased this series over
pm/bleeding-edge, that has all your patches.
I have moved ahead and done few more changes in this series, that should
get rid of all the lockdeps we were getting earlier, that includes
fixing lockdep issue in update_sampling_rate() that we were chasing.
These are pushed here again:
git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm.git cpufreq/governor-kobject
@Juri/Shilpa: Can you please confirm if all the issues got resolved now
?
V2->V3:
- The first patch from V2, that was moving min_sampling_rate to
per governor structure was dropped, as you suggested.
- Also, I have moved common tunables to struct dbs_data now, which you
also suggested sometime back.
- Last 5 patches are all new and fix rest of the issues we were facing.
