[PATCH] PM / OPP: Fix parsing of opp-microvolt and opp-microamp properties

by Bartlomiej Zolnierkiewicz

Commit 01fb4d3c39d3 ("PM / OPP: Parse 'opp-<prop>-<name>' bindings") broke support for parsing standard opp-microvolt and opp-microamp properties. Fix it by setting 'name' string to proper value for !dev_opp->prop_name cases. Cc: Viresh Kumar <viresh.kumar(a)linaro.org> Cc: Lee Jones <lee.jones(a)linaro.org> Cc: Rafael J. Wysocki <rafael.j.wysocki(a)intel.com> Fixes: 01fb4d3c39d3 ("PM / OPP: Parse 'opp-<prop>-<name> 'bindings") Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie(a)samsung.com> --- This fixes Exynos4x12 cpufreq-dt support regression present in linux-pm/linux-next tree.

[PATCH] sched/fair: update scale invariance of pelt

by Vincent Guittot

The current implementation of load tracking invariance scales the load tracking value with current frequency and uarch performance (only for utilization) of the CPU. One main result of the current formula is that the figures are capped by the current capacity of the CPU. This limitation is the main reason of not including the uarch invariance (arch_scale_cpu_capacity) in the calculation of load_avg because capping the load can generate erroneous system load statistic as described with this example [1] Instead of scaling the complete value of PELT algo, we should only scale the running time by the current capacity of the CPU. It seems more correct to only scale the running time because the non running time of a task (sleeping or waiting for a runqueue) is the same whatever the current freq and the compute capacity of the CPU. Then, one main advantage of this change is that the load of a task can reach max value whatever the current freq and the uarch of the CPU on which it run. It will just take more time at a lower freq than a max freq or on a "little" CPU compared to a "big" one. The load and the utilization stay invariant across system so we can still compared them between CPU but with a wider range of values. With this change, we don't have to test if a CPU is overloaded or not in order to use one metric (util) or another (load) as all metrics are always valid. I have put below some examples of duration to reach some typical load value according to the capacity of the CPU with current implementation and with this patch. Util (%) max capacity half capacity(mainline) half capacity(w/ patch) 972 (95%) 138ms not reachable 276ms 486 (47.5%) 30ms 138ms 60ms 256 (25%) 13ms 32ms 26ms We can see that at half capacity, we need twice the duration of max capacity with this patch whereas we have a non linear increase of the duration with current implementation.

[LSK] linaro-android topic branches updated for 15.12

by Amit Pundir

Hi Kevin, Alex, There are no linaro-fixes to go on top of lsk-v3.14-android and lsk-v3.18-android this time around as well. So please pull aosp/android-3.{14,18} directly into linux-linaro-lsk-v3.{14,18}-android for 15.12. Also now that android-4.1[1] is no longer experimental, I have prepared a lsk-v4.1-android topic branch[2] which you can pull from: git://android.git.linaro.org/kernel/linaro-android.git linux-linaro-lsk-v4.1-android Regards, Amit Pundir [1] https://android.googlesource.com/kernel/common/+log/android-4.1 [2] https://android-git.linaro.org/gitweb/kernel/linaro-android.git/shortlog/re…
