Hope you're following linaro website regularly :)

May be an interface for switching between hotplug, single core, dual core and 'gokhan mode' (with aftr and sched_mc) in the legendary app we're all waiting for? :D

I also have problem with beta10 and checkrom 3.1.1

I don't have any voltage control script in init.d but, when I use the program, the phone freeze or reboot. I move back to beta6
[Galaxy S II Original Android Development] antt00:
I already manually delete the script. When i want to change to my setting of sio + lazy + 200-1200mhz it freezes when i click apply. Haven't even got to UV yet. Maybe those settings are part of the limitation. :D Oh and i have repeated this freeze twice in a row. Back to beta 8 for me.
[Galaxy S II Original Android Development] gokhanmoral:
maybe the UV values are still the same for voltagecontrol app.

anyway, I disabled UV completely on darkknight edition.

you can redownload it and try again.
[Galaxy S II Original Android Development] navodwickra:
sorry my bad BLN works fine on MIUI roms :D
[Galaxy S II Original Android Development] antt00:
I check the UV they were stock. Plus all my previous UV setting is only -50mV. Could be some conflict with voltage control app.
[Galaxy S II Original Android Development] iamsmallpang:
just flashed beta10

CRR 3.1.1 had not problem

working fine , smooth

setcpu max 12000 min 100 lulzactive

screen off profile max 500 min 100 ondemand
[Galaxy S II Original Android Development] SilverMist1:
can we enable SCHED_MC by adding “echo 0 > /sys/devices/system/cpu/sched_mc_power_savings” in a init.d scrpit
[Galaxy S II Original Android Development] gokhanmoral:
then it may be a bug in my limiting code. I will check it and if I find a problem in that code I will reenable lighter version of undervolting for darkknight edition. normally there will be a single release for the kernel and I will send this modified version to GadgetCheck but I thought it would be nice to have the community's help for testing :)
[Galaxy S II Original Android Development] gokhanmoral:
I will follow linaro website more often.

I didn't know that they were so active. I am still new to this world and learning :)

[Galaxy S II Original Android Development] droidphile:
Value 0 is for disabling.

Value 2 means it's enabled via load balancing.

sched_mc is supported only in 2.2 beat 9. Beta 10 has it disabled.
[Galaxy S II Original Android Development] BoneMo:
NOT-DK edition coming too or should i wait for B11??
[Galaxy S II Original Android Development] navdra:
Can't do.

FAT system of SD card does not allow to create one.

Couldn't access ext. SD card at all.

Also, CWM recovery not seeing Internal memory is turn off for me.

Skipping b10.

I believe that proper solution would be to rewrite parts of the code of CWMManager app so it knows where to look for backups and leave default mount /mnt/emmc alone. If I'm not mistaken CWMManager is the reason why you moved mount point of external SD card.
[Galaxy S II Original Android Development] BoneMo:
hmm will stay with Beta8...your problems+no UV edition,,,,,want UV because after long trying i have found my stable values which are not able to set on Beta10.1
[Galaxy S II Original Android Development] energie:
I'm skipping beta10 too,got some freeze and reboots.

went back to beta 9
[Galaxy S II Original Android Development] gokhanmoral:
With 10 or 10.1?
[Galaxy S II Original Android Development] veyka:
I also had a freeze with 10.1, i could turn the screen on and off with the power button but no response to touch inputs, luzactive 200-1200 with no undervolt.
[Galaxy S II Original Android Development] knzo:
Why do you have the loopback quadrant hack on your kernel?

So people can make 7000 on quadrant and think it's real?

Remove this. There's a "silent agreement" between developers to not include this on ROMs, kernels, whatever.
[Galaxy S II Original Android Development] droidphile:
Knzo, it's because people are quadraholic! (They also need o% loss overnight and 10 hours screen on time along with this score :) )

[Galaxy S II Original Android Development] frankcilo:
Hi Gokhanmoral, but this kernel every time it finishes charging do the battery calibration? If so, how do you exclude this feature? Why, after calibration, the autonomy is reduced and it settles after a few charging cycles. Instead, if we calibrate each charge, we will never have a real and effective autonomy!

Thanks
[Galaxy S II Original Android Development] antt00:
The batt is only calibrated once. It will put .battery-calibrated in /data once done. If you want to recalibrate then delete this file.

If you have a Japanese version the SC-02C from NTT Docomo you use the NTT one. Everyone else uses the other one

---------- Post added at 02:43 PM ---------- Previous post was at 02:42 PM ----------

Is anyone using betterbatterystats? I have started using it since my battery drain has always been pretty quick. It seams that the phone is not going into deep sleep. I have noticed since I have had it unplugged it used up 15-20% pretty fast and I only had 15 min of screen time but over an hour of awake and the wake locks were pretty minimal.

any ideas? I am using 1.7.2 the NTT version.
[Galaxy S II Original Android Development] ebliss:
My random reboot problem seems to be solved by changing the governor from smartassV2 to ondemand.
[Galaxy S II Original Android Development] gokhanmoral:
Was it reboot our lockup and are you using 1.7.2?
[Galaxy S II Original Android Development] ebliss:
I get random reboots and lockups since rc3. I am using 1.7.2 atm. I posted this when I was using smartassV2 with 1.7.2.
[Galaxy S II Original Android Development] bgx:
Just at the moment a random freeze here to with 1.7.2; last night I couldn't turn wifi on (shows only "Error").

I'm on smartassv2 with 100-1000mhz and a little UV 100;200;500 with 925 mv 800 with 975 mv and 1000 with 1075 mv gpu 100-267 UV at 850/950 mv

Don't want to cut of at 200mhz and don't want to change to ondemand. Will try a bit more...
[Galaxy S II Original Android Development] grisha1:
Also had a frozen phone this morning. After 2.5h of deep sleep it happened. 10 secs power button to reboot.

1.7.2, no UV, smartass down to 100 MHz.

[Galaxy S II Original Android Development] eybee1970:
I found out that probs with lockups or random reboots happen with CustomROMS using Kernel-tweaks in /system/etc/init.d...e.g. on Exynos: there is 'S98exynos' in init.d-Folder causing freezes with Siyah-Kernel - when you remove, no more problems.

I guess it's caused by one of following lines inside 'S98exynos:

That means, that tweaks brought by Siyah-Kernel missmatch with some kernel-tweaks in certain ROMs...
[Galaxy S II Original Android Development] Mayday_XL:
I have some problems with the Root Explorer, my S2 freezes sometimes (v 1.72). :confused:
[Galaxy S II Original Android Development] c4lamity:
That is incredible! I have 70% after 8 hours of pure idle time, haven't touched the phone at all. I use that gpu uv script from OP and cpu is uv as well using ondemand in setcpu. Should try smartassv2 maybe?

Deep sleep and 100mhz does work according to cpyspy. I am on xpower+ sp3 with siyah1.7.3 ATM posted by smaberg but got same batt drain 1.7.
[Galaxy S II Original Android Development] kwerdenker:
Yeah, because these ROM cookers put undervolting as a standardfeature in their init-script which they shouldn't really do. It should be up to the user if he wants to do it or not.

In this case the problem lies in the missmatch between the frequency steps in whatever kernel he is using in his rom and this kernel. His kernel has less steps than ours and when you echo this kinda string into this kernels UV_table and do a cat afterwards, you'll see how messed up things are.

Maybe I should put some more work into my adaptive UV script and release it in the development forum so they at least make sure their UV works with every possible kernel...

search the thread to find the discussions about this.

I don't know that silent agreement. and it is already removed by a another request. it wasn't there for all the versions. I have already said this several times, one more time I say: I wish I could make the quadrant score worse and if I could I wouldn't care any silent or written agreement about that.

did you read the comment on that part, by the way?

@gokhanmoral

I read in your....mmmhhh blog? (how should I call the webpage where you put your kernels?)

well, I read in your blog, that in beta 11 you will disabled hotplug_cpu by default, what you'll do this? what is the advantage?

thanks!!
[Galaxy S II Original Android Development] crypticc:
Read " enabled SCHED_MC and AFTR"

And then back a half dozen pages.

[Galaxy S II Original Android Development] SilverMist1:
so by disabling hotplug, 2 cores will always be active right? will there be a way to enable hotplug?
[Galaxy S II Original Android Development] gokhanmoral:
tegrak 2nd core app is still supported.

but use it if you want to use only one core.

or disable sched_mc before enabling dynamic mode.
[Galaxy S II Original Android Development] Piretia:
the link does not work for b11
[Galaxy S II Original Android Development] BoneMo:
so to be sure one core option will work and dynamic 1or2 core not ?or just i must not tick the dynamic mode ?sorry i dont understand it...or what will happen when i set dynamic mod without disabling sched_mc....how to disable it when needed ?
[Galaxy S II Original Android Development] myfluxi:
From my understanding AFTR is enabled only when just core0 is active. There pm-hotplug and AFTR go hand in hand. Check out s5pv310_enter_lowpower().
[Galaxy S II Original Android Development] crypticc:
That's beta 9 setting isn't it? I.e. before he knew they were mutually exclusive
[Galaxy S II Original Android Development] gokhanmoral:
hmm, right.. I looked at that part again.

then when I disable hotplug (by just preventing the second core to become offline) I also do not use AFTR at all, right?

did you disable hotplug_cpu while using sched_mc and also did not enable AFTR?

EDIT: ok. sched_mc usage doesn't make sense when we use hotplug_cpu, right? (as I have read on several articles on linaro website). but again, since we have 2nd core support it still makes sense to keep AFTR enabled.
[Galaxy S II Original Android Development] BoneMo:
so by disabling hotplug, 2 cores will always be active right? will there be a way to enable hotplug?

tegrak 2nd core app is still supported.

but use it if you want to use only one core.

or disable sched_mc before enabling dynamic mode.

so in the 2nd core app will dynamic hotplug not work ?? or will phone run only in 2 core mode or how....last few posts are confusing me...:confused::confused::confused::confused:
[Galaxy S II Original Android Development] AndreiLux:
I do not understand at all why you would want to remove/disable hotplug functionality. Neither sched_mc nor AFTR have anything to do with that.

https://wiki.linaro.org/WorkingGroups/PowerManagement/Specs/sched_mc
[Galaxy S II Original Android Development] gokhanmoral:
I am searching for the article where it was advised disabling hotplug when using sched_mc.

also, there is a strange "lagging" when switching the second core on or off.

it is much more smooth when using either only one core or both cores.

I thought that it was related with the code in cpufreq_stats.c but disabling it didn't help. there is still noticable difference.

EDIT: I could not find that article or maybe I misunderstood something. anyway.. It's too late. I have uploaded beta11 with hotplug enabled. I think there is no known problems in this release. please test and report. it's already very late here.. so, good night.
[Galaxy S II Original Android Development] AndreiLux:
Keep in mind that the multicore scheduling and all of those articles are designed, or targeted at higher cored systems and especially multi-socketed systems, none of the our phone really has. I didn't go into depth too much on what the effects would be on a simple dual-core.

I also do not think it would be wise to keep the 2nd core on, whatever much the hotplug itself costs in terms of power. Somebody with time can put the phone into airplane mode, do an "echo bananas > /proc/wakelocks" (Or whatever it was to set a wakelock, I forgot), and do an overnight run with forced 1-core compared to forced 2-core idling.

And anyway; you set the topology level to 2, which is useless on the Exynos.
[Galaxy S II Original Android Development] SilverMist1:
so in final version of beta11 hotplug is still enabled?
[Galaxy S II Original Android Development] gokhanmoral:
that test will be interesting. I am sure there are people who has time for that experiment (1-core vs 2-core while keeping the device awake)

http://www.mail-archive.com/linaro-dev@lists.linaro.org/msg08005.html

and in this post "...cpu hotplug (which is not a power saving feature)..." may have changed my mind about hotplugging...

and you are right about topology level. I changed it to 1 and uploading...

EDIT: tar uploaded but I could not delete CWM zip because it is in use. I will change the link
[Galaxy S II Original Android Development] crypticc:
It's or correct that manual suggests echo 1 it's most appropriate for power saving on single CPU dual core mode. I.e. load up first core first?

[Galaxy S II Original Android Development] :
Hmm.. i'm curious : what did you do to recreate it? I would like to know if i should have seen what was wrong...
[Galaxy S II Original Android Development] gokhanmoral:
external sd is mounted to /mnt/emmc in CM7

but CWMManager looks for the backups on externalsd in /mnt/sdcard/external_sd folder

so, I have mounted external_sd to /mnt/sdcard/external_sd by making a modification in init.rc

but also, I created a symbolic link from /mnt/emmc to /mnt/sdcard/external_sd not to break anyhing...

but that caused some programs (gallery or media managers) to index media twice because they are searching both directories which are pointing to the same location.

then I removed /mnt/emmc. but apparently, CM7 tries to scan the device which is pointed by /mnt/emmc and it waits for that folder to be mounted.

now, I created /mnt/emmc symlink again and put one more line to post-init.sh to wait for 30 seconds and then remove that link.

however, it doesn't work. I will try to solve that problem later. but it is not a big problem anyway.

now you have your external sd mounted to /mnt/sdcard/external_sd and you have a symbolic link from /mnt/emmc to /mnt/sdcard/external_sd.

Ok so far Beta 11 no freezes like beta 10. But for not so technical person like me :confused:, are both cores suppose to be online all the time for beta 11 (sched_mc = 1) cos 2nd core app indicates CPU 1 still goes offline.

Gokhan, did you revert the 2nd core active threshold back to 60 (or 50).

Because in hotplug, i can see 2nd core kick in too often.

Because of this, LP app drawer lag while scrolling slowly in lulzactive is back.

Even linpack gives higher scores on multithread run in hotplug as compared to beta9. So definitely, 2nd core is kicking in too often.

Could the reason be any conflict with aftr and sched_mc?
