Computing the dynamic-power-coefficient on Exynos5422

by Oliver Effland

Hello everyone, I hope this is the right place to ask, otherwise please just point me in the right direction. I'm currently testing the EAS patches [v4] on an ODROID-XU3 board, which has an Exynos5422 SoC. However, the corresponding DT is missing the "dynamic-power-coefficient" that is needed for an appropriate EM. So I'm trying to compute the dynamic-power-coefficient according to the formula: Pdyn = dynamic-power-coefficient * V^2 * f The frequency f is given by the DT.The actual Voltage and Power are determined by means of the on-chip sensors (returns the values for the specific cluster). When using the Voltage given in the DT, the differences for the d-p-coefficient are negligible. So I'm calculating the d-p-coefficient (mW/MHz/uV^2) by reading out the following SoC sensor values. For the little cluster (A7): frequency(MHz) Voltage(V) Power(mW) Dynamic-power-coefficient 200 0.9175 49.470 ~2.938*10^-13 400 0.9165 91.892 ~2.736*10^-13 600 0.9638 149.454 ~2.682*10^-13 800 1.0263 223.453 ~2.652*10^-13 1000 1.1000 327.707 ~2.708*10^-13 1200 1.1725 445.899 ~2.703*10^-13 1400 1.2713 627.010 ~2.771*10^-13 For the big cluster (A15): frequency(MHz) Voltage(V) Power(mW) Dynamic-power-coefficient 200 0.9162 159.676 ~9.510*10^-13 500 0.9138 325.480 ~7.797*10^-13 800 0.9288 511.360 ~7.410*10^-13 1100 1.0063 828.020 ~7.434*10^-13 1400 1.0713 1209.774 ~7.530*10^-13 1700 1.1750 1835.784 ~7.822*10^-13 2000 1.2700 2661.849 ~8.252*10^-13 But those values are way off for the DT, unless I multiply the d-p-coefficient with 10^15. Assuming the Power value needs to be subtracted by a static component (power usage when idle), the results change as follows: For the little cluster (A7): frequency(MHz) Voltage(V) P-dyn(mW) Dynamic-power-coefficient 200 0.9175 36,381 ~2,160*10^-13 400 0.9165 73,438 ~2,186*10^-13 600 0.9638 122,470 ~2,197*10^-13 800 1.0263 184,135 ~2,185*10^-13 1000 1.1000 270,425 ~2,234*10^-13 1200 1.1725 367,121 ~2,225*10^-13 1400 1.2713 513,989 ~2,271*10^-13 For the big cluster (A15): frequency(MHz) Voltage(V) P-dyn(mW) Dynamic-power-coefficient 200 0.9162 99,834 ~5,945*10^-13 500 0.9138 244,651 ~5,860*10^-13 800 0.9288 401,986 ~5,825*10^-13 1100 1.0063 664,565 ~5,966*10^-13 1400 1.0713 985,268 ~6,132*10^-13 1700 1.1750 1494,173 ~6,366*10^-13 2000 1.2700 2086,273 ~6,467*10^-13 While looking for examples in the kernel that calculate the dynamic-power-coefficient, I found this patch [1] by Caesar Wang that introduced this value for the rk3399 big cluster. Unfortunately, I'm unable to reproduce the same results for the coefficient with the given values. My results are also with a 10^-13 factor and even when I scale them with 10^15, my results have a certain margin of error: > frequency(MHz) Voltage(V) Current(mA) Dynamic-power-coefficient (My) d-p-coefficient > 24 0.8 15 > 48 0.8 23 ~417 ~598 > 96 0.8 40 ~443 ~520 > 216 0.8 82 ~438 ~474 > 312 0.8 115 ~430 ~460 > 408 0.8 150 ~455 ~459 Is this the right approach, or am I missing something? Hope someone can help me out. Thanks in advance, Oliver Effland [1] https://patchwork.kernel.org/patch/9861505/

"WALT wallclock appears to have gone backwards or reset" warring question. Thanks!

by Wu Gang(吴刚)

Hi all, When using WALT for EAS scheduler( android common 4.4 code base with commit fe09418d6f88b55920c576166b6e6a5ad456920f ), I met “WALT wallclock appears to have gone backwards or reset” WARNING. This warring is very hard to duplicate, and I met two times totally (for one time: wallclock is 64090104834350 and rq->window_start is 64255280000001 , windown_start is wrong). I am wondering is there anyone else meet similar issue as me? Or is this one known issue ? Thanks very much!

[RFC eas-dev] sched/fair: Skip pelt update if preempted by RT

by Joel Fernandes

From: "Joel Fernandes (Google)" <joel(a)joelfernandes.org> Here's a very rough patch just to discuss prevention of decay of CPU/task's util_avg signal incase its preempted by RT or DL. Its likely not correct and needs more work but it solves the issue I see with my synthetic test. To reproduce the issue, I wrote a synthetic rt-app test with RT task preempting a 100% CFS task for 300ms. https://pastebin.com/raw/rXNmRUZY I have seen in traces that the util_avg decays quickly even before the RT task sleeps. The idea is to mark the CFS class from put_prev_task_fair if the task was running while the put_prev_task() happened and unmark it from pick_next_task_fair. This approach also keeps the solution of this within CFS without modification to other classes. What do you think? Note: - Just for demo/trial, I took a full int from sched_avg. I am open to any ideas on a flag we can set, all that's needed is 1 bit. - The current UTIL_EST design cannot prevent this issue because it relies on task's sleeping and infact could be affect by this issue itself incase task's util-est EWMA hasn't built up. - Vincent's patches for PELT in DL/RT are still needed for correct OPP selection and estimation of capacity_of etc. This patch solves a different issue.

prefer_idle behavior in android-4.14

by Chris Redpath

Hi, Joel was looking at something else in android-4.14 wakeup path and he noticed that we have a difference in behavior for prefer_idle tasks when we're using find_best_target, so he asked if we could discuss that here. Behavior in android-4.9 and earlier ----------------------------------- When we find an idle CPU for a task which has the prefer_idle attribute, we immediately return that CPU from the energy-based wakeup CPU selection. This happens in slightly different places over the EAS and android versions but it is always true that we take the recommended idle CPU for tasks in this class. How that changed in android-4.14 -------------------------------- android-4.14 has two different wakeup paths, selected with a sched_feature FIND_BEST_TARGET. This defaults to true with the intent of preserving the previous behavior. Both paths are different, so I'll describe them below separately. The two paths however share some common code - the way we integrated EAS with the regular wakeup code is different in android-4.14. There were two reasons for doing this. 1. minimize the differences in select_task_rq_fair wrt mainline code 2. make better use of the per-sd overutilization flags Since we have per-sd overutilised flags, we attempt to perform an EAS wakeup at the highest non-overutilised sched_domain - meaning that we can still perform an energy-aware wakeup for small tasks inside a non-overutilized group of small CPUs while potentially other groups of CPUs are overutilized. The decision about attempting to use energy awareness is taken in wake_energy function at the top of strf - all the cases where we can't use energy-awareness are ruled out, and the decision about using find_idlest_cpu/EAS for prefer_idle tasks is also done here. If we are using energy aware wakeups, then we will find the highest non-overutilised SD to wake in. In all cases where we do an energy aware wakeup but don't find any suitable candidate CPUs we will go on to use find_idlest_cpu. android-4.14 sched_feat(FIND_BEST_TARGET) true wakeup path ---------------------------------------------------------- When FIND_BEST_TARGET sched feature is on (the default), we call find_best_target to populate the energy_env structure. This takes note of the prefer_idle flag and the task boost to change which task placement strategy will be used - the algorithm is the same as in previous versions of android. However in android-4.14 (unintentionally) the prefer_idle task placement is not immediately acted upon - when a prefer_idle task is placed, we will select the first idle CPU we see *but* this will become the target CPU and we will still perform an energy diff and select between prev/target based upon energy requirement. The open question is - now that we have realized that there is a different strategy in place, should we change it to be the same as the old version? I think that we should - it will be a simple change to use the idle cpu selected immediately without the energy diff. All we would need is to add something like this: --- a/kernel/sched/fair.c +++ b/kernel/sched/fair.c @@ -7383,7 +7383,7 @@ static int find_energy_efficient_cpu(struct sched_domain *sd, } } else { int boosted = (schedtune_task_boost(p) > 0); - int prefer_idle; + int prefer_idle, target_cpu; /* * give compiler a hint that if sched_features @@ -7396,10 +7396,18 @@ static int find_energy_efficient_cpu(struct sched_domain *sd, eenv->max_cpu_count = EAS_CPU_BKP + 1; /* Find a cpu with sufficient capacity */ - eenv->cpu[EAS_CPU_NXT].cpu_id = find_best_target(p, + target_cpu = find_best_target(p, &eenv->cpu[EAS_CPU_BKP].cpu_id, boosted, prefer_idle); + /* immediately select idle CPUs for prefer-idle tasks */ + if (prefer_idle && target_cpu >= 0 && + idle_cpu(target_cpu))) + return target_cpu; + + /* place target into NEXT slot */ + eenv->cpu[EAS_CPU_NXT].cpu_id = target_cpu; + /* take note if no backup was found */ if (eenv->cpu[EAS_CPU_BKP].cpu_id < 0) eenv->max_cpu_count = EAS_CPU_BKP; It could be the case that there are energy advantages to performing an energy diff for prefer_idle tasks, we've tried a few times to come up with a way to use lower-energy CPUs for these tasks where possible (for cases like full-screen video playback or screen-off audio playback) without harming the interactive response, but we haven't managed to come up with anything which doesn't need per-platform tuning which isn't really suitable. The underlying requirement for these prefer_idle tasks is that they should ideally not be preempted as they are likely to be part of the critical frame drawing path. We should also note that the EAS_PREFER_IDLE sched_feature potentially also has an effect on this - if we are using find_best_target and we do not have EAS_PREFER_IDLE set to true (true is the default), then we don't pass the prefer_idle status of the task to find_best_target - however if EAS_PREFER_IDLE is not true, we should have avoided entering find_energy_efficient_cpu in the first place. To be complete, there is also a further sched_feat for task placement which controls how we evaluate the energy requirement for a task. If FBT_STRICT_ORDER is on (the default), we will select the first CPU we find which saves energy compared to the prev_cpu. This matches previous versions of android. We have been experimenting with selecting the most efficient out of the target/backup CPUs provided by find_best_target, if FBT_STRICT_ORDER is false this is what the scheduler will do. In testing there isn't really a clear winner out of these options, so I added the sched feature so users could play with the options easily on their platforms without code changes. android-4.14 sched_feat(FIND_BEST_TARGET) false wakeup path ----------------------------------------------------------- This uses the brute-force placement strategy from the pre-simplified-EM mainline EAS patch set, inside the android energy diff algorithm. In android, we collect all the potential CPU placement options in a data structure, and then evaluate the energy for all of them at each sched_domain traversal level. This is done to avoid visiting each domain & group more than once. Other than the switch to the new energy calculation method, the energy required is still calculated for every allowable CPU and then the option which has the lowest overall consumption is selected. When it comes to dealing with prefer_idle tasks, there is another optional behaviour in this mode. If you have sched_feat(EAS_PREFER_IDLE) set to true (the default), then prefer_idle tasks have no special treatment in the energy-aware wakeup path. This means they will get the lowest-energy option with no regard to idleness. However, if EAS_PREFER_IDLE is false (i.e. don't use EAS for prefer-idle tasks) then we route these tasks through the slow path wakeup code - the decision is made inside wake_energy, which propagates through to calling find_idlest_cpu instead of find_energy_efficient_cpu. If the find_best_target feature FBT_STRICT_ORDER is true (the default) then the first CPU which saves energy compared to default will be selected rather than the most efficient. When combined with the brute force selection algorithm, this will result in the lowest-numbered cpu which saves energy over the prev_cpu being selected. This is not the way that the brute force (mainline-alike) placement is intended to work, so when using brute force (FIND_BEST_TARGET=false) one should also turn off strict ordering (FBT_STRICT_ORDER=false) *and* opt out of using EAS for prefer_idle tasks (EAS_PREFER_IDLE=false). --Chris

Android kernel 4.14: warning in walt_fixup_busy_time()

by Leo Yan

Hi all, I can reproduce the warning from WALT function walt_fixup_busy_time() in Android kernel 4.14 on Hikey960 board. The detailed log is as below. To trigger this issue, I usually reboot the board for multiple times: 'while true; do adb reboot; sleep 30; done' and at the boot time this issue can be reproduced. Before dig into this, I share the log to check in case we have the fixing yet for it. Thanks, Leo Yan --- log --- console:/ $ [ 9.260172] read descriptors [ 9.263096] read strings [ 9.267978] wlcore: wl18xx HW: 183x or 180x, PG 2.2 (ROM 0x11) [ 9.272518] wlcore: loaded [ 9.348146]
