3.10-rcX: cpu governor ondemand doesn't scale well after s2ram

At a stable 32bit Gentoo Linux with a i5 processor (2.6 GHZ max, 3.1 GHz boost) I've to change the governor after a s2ram all 4 cores from "ondemand" to "performance" and back to "ondemand", otherwise cpu1 till cpu3 would stay after s2ram at 2.6 GHz (whilst cpu0 is at the expected 800 MHz if no load is at the system) - FWIW I do set ignore_nice to "1".

3.9.6 is ok, the bug was introduces somewhere in 3.10-rcX.

FWIW the following commands circumvents that issue :

# for i in $(seq 1 3); do echo performance > /sys/devices/system/cpu/cpu$i/cpufreq/scaling_governor; done
# for i in $(seq 1 3); do echo ondemand    > /sys/devices/system/cpu/cpu$i/cpufreq/scaling_governor; done

cpu0 is unaffected

Hmm. This looks like something unrelated to the previous reports.

How do you check the frequencies?

Does that happen every time? If so, any chance to bisect driver/cpufreq changes between 3.9 and now?

Does it work without ignore_nice?

yes

much more significant is the temperature :

$> cat /sys/devices/system/cpu/cpu\?/thermal_throttle/package_power_limit_count /proc/acpi/ibm/fan /sys/class/hwmon/hwmon\?/device/temp\?_input'

- it is around 49° if just 4 BOINC childs are running at nice level -19, but it is above 65°C if the issue exists. And in hat case I just do run

$> for g in performance ondemand; do for i in 0 1 2 3; do echo $g > /sys/devices/system/cpu/cpu$i/cpufreq/scaling_governor; done; done; echo 1 > /sys/devices/system/cpu/cpufreq/ondemand/ignore_nice

and the system is back to normal.

first bisect attempts failed. I realized that the issue only occurs if the power is plugged in. If the system is running on battery the issue doesn't occurred (I checked it more than once)

Seems not to be related to that.

Well, I'm not aware of any recent changes in cpufreq that would make things work differently depending on whether or not AC power is used.

Thanks,

Toralf,

It would be helpful if you can do git bisect and let us know which patch created this problem. Otherwise its very difficult to trace it.

Yep, but 14 commits to bisect and about 20-30 min for each - will see, when I find a time slot.

Just FWIW thie following is now a good indicator for the issue - that's the picture after wakeup, where I'd expect always 800 MHz:

$ sudo cat /sys/devices/system/cpu/cpu?/cpufreq/cpuinfo_cur_freq
800000
2601000
2601000
2601000

Hmm..

Can you give dumps of complete cpufreq directories for all cpus before and after s2r. That may give us some hint about the problem.

here it is:

Do you have CONFIG_NO_HZ_FULL set by chance?

Rafael

Hmm.. So this is what I make out of it.
scaling_cur_freq: is the freq which cpufreq core thinks is set. Which is correct. 800 MHz.

cpuinfo_cur_freq: is the actual freq in hardware, which is wrong. @Rafael: If I am not wrong we have seen this earlier too in last few months. There was some problem with bootloader or something else I can't remember.

The latest bisect attempt gave :

cpufreq: Preserve sysfs files across suspend/resume

The file permissions of cpufreq per-cpu sysfs files are not preserved across suspend/resume because we internally go through the CPU Hotplug path which reinitializes the file permissions on CPU online.

But the user is not supposed to know that we are using CPU hotplug internally within suspend/resume (IOW, the kernel should not silently wreck the user-set file permissions across a suspend cycle). Therefore, we need to preserve the file permissions as they are across suspend/resume.

The simplest way to achieve that is to just not touch the sysfs files at all - ie., just ignore the CPU hotplug notifications in the suspend/resume path (_FROZEN) in the cpufreq hotplug callback.

To get a more reliable bisect result I had to start BOINC before (4 childs each with nice -19 started)

Well, to be honest, I'm not really sure how the above commit can cause the problem you're seeing to happen ...

Srivatsa, Viresh, any ideas?

Rafael

I speak only for myself.
Rafael J. Wysocki, Intel Open Source Technology Center.

I don't. But its very simple to get this checked isn't it? Just revert this patch on top of your kernel (leave bisect) and see if gets fixed.

I do (mostly) check a bisect result before I post it to a mailing list to not blame the wrong commit to be guilty (b/c - erm - I did it in the past).

Said that I finished bisect, checked out commit a66b2e5, tested it (has the issue), did "git show a66b2e5 | patch -p1 -R" and checked that result (no issue).

I tried to look up what problem is being reported, but apart from the hint from the subject line, I couldn't find anything more. So, guessing that there is something wrong with cpufreq after an s3 cycle, Toralf, can you please try out the below patch and see if it improves anything? (Don't revert anything, just apply the below diff on a problematic kernel and see if it solves your issue).

Subject: [PATCH] cpufreq: Fix cpufreq regression after suspend/resume

Toralf Förster reported that the cpufreq ondemand governor behaves erratically (doesn't scale well) after a suspend/resume cycle. The problem was that the cpufreq subsystem's idea of the cpu frequencies differed from the actual frequencies set in the hardware after a suspend/resume cycle. Toralf bisected the problem to commit a66b2e5 (cpufreq: Preserve sysfs files across suspend/resume).

Among other (harmless) things, that commit skipped the call to cpufreq_update_policy() in the resume path. But cpufreq_update_policy() plays an important role during resume, because it is responsible for checking if the BIOS changed the cpu frequencies behind our back and resynchronize the cpufreq subsystem's knowledge of the cpu frequencies, and update them accordingly.

So, restore the call to cpufreq_update_policy() in the resume path to fix the cpufreq regression.

But if I do apply that patch on top of kernel 3.10 then it has no effect

Weird. So I think something *else* got broken by some other patch, _after_ a66b2e5. Viresh, do you have any suspect commits in mind?

Regards,
Srivatsa S. Bhat

If I was God I could have. But as I am a poor human being I need more details (preferably with git bisect) :)

--
Viresh

Haha :)

Coming to git bisect, I think it needs to be done between a66b2e5 + this-patch and 3.10 + this-patch, to ensure that we look for problematic commits in-between a66b2e5 and 3.10 (to avoid the bisect result ending up at a66b2e5 again).

Regards,
Srivatsa S. Bhat

Exactly!!

Toralf,

Try reverting these patches in the order specified (revert both) 419e172145cf6c51d436a8bf4afcd17511f0ff79 c28375583b6471c1cb833a628ab6afb5b69079d0

They are touching ondemand governor and this may be creating some problems. But I am not sure about it, I must admit.

Ok, I did a mistake here (Thanks Srivatsa for telling me), this wasn't there in 3.10 but 3.11-rc1

So just try reverting about commit.

In case you are using acpi-cpufreq driver, please try reverting this before above one:

8673b83bf2f013379453b4779047bf3c6ae387e4

It is playing with how frequencies are reported and may be the culprit.

I reverted 8673b83b on top of 3.10.0 - no success, then I reverted c2837558 too - no success.

MfG/Sincerely
Toralf Förster
pgp finger print: 7B1A 07F4 EC82 0F90 D4C2 8936 872A E508 7DB6 9DA3

I assume that you have applied the patch given by Srivatsa earlier over these reverts?

In that case you can go for a revert I believe. There aren't many cpufreq patches between 3.10 and the commit where you tested successfully earlier.

But I now also suspect that this might have been caused by something outside cpufreq.

yes

+1

At least the likelihood is big and the "saving" to narrow down bisecting just to the cpufreq patch is small compared to the "cost" of the risk of an unwanted side effect. OTOH not sure when I find a time frame for the bisect nightmare.
That's why I tweaked my s2ram script in this way:

+ if [[ "$1" = "mem" && "$(uname -r)" = "3.10.0" ]]; then
+ echo " tweak governor ..."
+ for g in performance ondemand; do
+ for i in 0 1 2 3; do
+ echo $g > /sys/devices/system/cpu/cpu$i/cpufreq/scaling_governor
+ done
+ done
+ echo 1 > /sys/devices/system/cpu/cpufreq/ondemand/ignore_nice
+ fi

Problem : yesterday I wasn't even able to 100% validate the issue at commit a66b2e5 + f51e1eb just b/c there's another issue which erratically happens here: sometimes cpu0 is too (not only cpu 1-3). In that case the frequency are set to 2.6 GHz for each coret instead of 800 MHz for cpu0 and 2.601 GHz for cpu 1-3.

Furthermore I've the strong feeling, that the plugged in USB devices might have an effect. And in the mean while I would not even exclude the influence of the type of the 4 BOINC tasks (Asteorid@Home versus Einstein@Home / World Community Grid which I have to run with nice -19 in the back ground) at the bisect results.

So all my ongoing attempts to bisect weren't successful till now.

I just tested the latest git tree from today (v3.10-8615-g23e3a1d) - although f51e1eb is merged - the origin issue (cpu 1-3 set to 2.601 GHz after wakeup) is still here.

Toralf Förster
pgp finger print: 7B1A 07F4 EC82 0F90 D4C2 8936 872A E508 7DB6 9DA3

I tested the patch several times on top of a66b2e5 - the origin issue is fixed but - erratically another issue now appears : all 4 cores are runs after wakeup at 2.6 GHz.
The temporary hot fix is to switch between governor performance and ondemand for all 4 cores.

Hi Toralf,

Thanks for all your testing efforts. The commit a66b2e5 took a shortcut to achieve its goals but failed subtly in many aspects. Below is a patch (only compile-tested) which tries to achieve the goal (preserve sysfs files) in the proper way, by separating out the cpufreq-core bits from the sysfs bits. You might want to give it a try on current mainline and see if it improves anything.

Regards,
Srivatsa S. Bhat

(Applies on current mainline)

Oops! You are right. Hmm, this looks quite difficult to get right :( There are multiple challenges here:

1. The sysfs files must not be removed during cpu_down, and not initialized

during cpu_up. That would help us preserve the file permissions.
2. But we should ensure that we really do the cpufreq-core parts of the cpu initialization during cpu_up. If we fail to free some of the data-structures during cpu_down, the cpu_up callback will think that a full-init is not required and not do its job. That will make cpufreq behave erratically after suspend/resume and take us back to square one.

3. A full re-init in the cpu_up callback also involves memory allocations. So if we don't release the memory in the cpu_down callback, we'll end up in a memory leak.

I tried to address all these in this patch, but you found yet another serious loop-hole. I guess I'm out of ideas now... if anybody has any thoughts on how to get this right, then I'm all ears. Else, we'll just revert the original commit like Rafael suggested and leave it upto userspace to save and restore the permissions across suspend/resume if it wants ;-(

If I understand correctly, the most concern is how to deal with per cpus' cpufreq_policy structure. If something wrong , please correct me.

For this case, cpufreq_policy must be reserved since all related cpufreq data and kobj is also store into it. We can't release it.

cpufreq_add_dev() checks whether the cpu has been attached cpufreq_cpu_data and associated kobj has been created. If yes, it would try to release it by cpufreq_cpu_put() and return directly. This seems to be conflicted with the above.

Even we remove the previous check, cpu scaling driver's init() also will change some data of struct cpufreq_policy and this is also what we don't like to see.

How about implement scaling driver's suspend/resume callback()? Although this needs to be dealt with case by case. If one's callbacks hasn't been implemented, it would have to follow current rule.

Asking as a naive outsider who is completely unfamiliar with the code, why are any of these things at all troublesome?

Can't cpu_up tell the difference between activating a brand-new CPU and reactivating one that was present before but was temporarily disabled?

Doesn't cpu_up know which data structures get freed when an active CPU is temporarily deactivated?

Doesn't cpu_down know what memory gets allocated in cpu_up? Can't it deallocate just the right parts for the type of transition it is doing?

It sounds like you're really asking how to make sure that cpu_up and cpu_down both know what the other is doing, so that each can do the opposite of the other. That doesn't sound hard.

Well, I'm now trying a slightly different approach at reorganizing the code, and so far I think I'll be able to get it right this time. Let's see how it goes.

It would not have been hard if the code had been already structured that way. Currently, the code is quite a bit entangled, and it doesn't distinguish the "temporarily deactivated" and the "fully torn-down" cases. To add to the mess, the code is generously sprinkled with notifiers that are invoked every now and then (which depend on previous init steps etc).

But the bottomline is that this is purely a code-reorganization issue, nothing more than that. And hopefully we'll be able to separate out the "temporarily deactivated" and the "fully down" cases reasonably well, such that we can preserve the sysfs file permissions easily across suspend/resume. That's the code reorganization I'm working on at the moment; I'll post it out as soon as I'm done.

Srivatsa's patch became commit f51e1eb63d ("cpufreq: Fix cpufreq regression after suspend/resume").

Well, a laptop I use seems to run into something related: the second of its two cores can get stuck at a fixed frequency after resume. Often it's its maximum frequency. That makes the CPU run hot, without actually doing much work. But it can also get stuck at its lowest frequency.

Please note that commit f51e1eb63d, which is part of v3.10.1-rc1, doesn't seem to cause this behavior. This issue can already be seen when running v3.10.0. So perhaps that commit just made this issue more noticeable to Toralf. But it's not clear to me what Toralf's origin(al?) issue actually was.

Anyhow, I suspect that the stuck frequency is a regression introduced in v3.10.0. But I have been unable to pinpoint it to a commit added in the v3.10 cycle through bisecting. I must have marked a commit good that was actually bad, just because a few suspend and resume cycles didn't trigger this issue. To be continued...

That workaround works here too. I switch the core that is stuck at a particular frequency to some other governor and then back to ondemand.

Thanks,

Paul Bolle

The culprit apparently is commit a66b2e503f ("cpufreq: Preserve sysfs files across suspend/resume"). Srivatsa submitted a patch to revert that commit (see https://lkml.org/lkml/2013/7/11/661 ). That revert seems to fix this issue too.

Paul Bolle

Thanks a lot for your tests and for confirming that the complete revert fixes your cpufreq issue.
