Hey guys!
Wanted to bounce a question off of all of you,
I have Uruk 1.0 installed, with Urukconfig 1.1.0, I also have SetCPU installed.
I'm looking to find the 'best' config to optimize my CPU governing....
SetCPU seems to take longer to 'set' due to SU permissions, but 'runs' just fine after booting - the system is nice and snappy, but there seems to be some slight bugs in it.... sometimes it wipes my settings out of it, especially after a reboot, but it is intermittant.
CPUGovernor in Urukconfig works well no matter how I cut it, but I am unsure how to set the scaling of the CPU.
One thing I did notice, between the two governors, if I have them both 'running' SetCPU reports 'interactive' scaling, while urukconfig reports 'ondemand' scaling... I think they might not like playing nice with each other, but don't quote me on that.
Any suggestions or comments?

I figured this out, go into /etc/uruk.conf and edit the cpugovernor file.

I think I may have 'fixed' this problem (I'm not sure though, I really hope I'm not screwing things up...)
I went into /sys/devices/system/cpu/cpu0/cpufreq and edited cpuinfo_min_freq to my desired 600000 (default 300000) and rebooted.
There seems to be no issues, SetCPU is now keeping my settings.
EDIT: Even after setting the cpu speeds manually, even making them read only permissions, the system resets them on reboot, seems like a fix described in this thread http://forum.xda-developers.com/showthread.php?t=1169625 may do the trick.
EDIT2 Between the script I wrote and killing SU to SetCPU, the system is no longer rewriting the cpu_min/max_freq - Thanks arpruss!

I can say, with the changes I implemented editing both the cpugovernor and cpuinfo_min_freq files, my system is most definitly running in interactive mode, but urukconfig still reports the mode as 'ondemand' - pretty sure it's not reporting correctly.
Im still open to thoughts on this, I would really like to hear what some of the seniors around here have to say
Cool, great info. What did you change in the cpugovernor file? Have you tried to change the Max freq yet? I'd love to get uruk to 1.2

I set my desired min / max cpu speeds, and set the governor to interactive mode (seems to be a bit peppier than ondemand)
Unfortunately the only way to overclock is a kernel capable of it, then setting everything appropriately. Uruk 0.7 has an OC kernel - try it out

ok, gotcha.
Yeah, I was afraid you says 0.7 was the only way. I was hoping you found a way on 1.0. I used to be on 0.7 with OC and I might go back.
Powersave CPU Manager
Automatically manages you cpu no matter what you use, ie. setcpu, cpumaster, virtuous_oc. This will automatically underclock your cpu and change the governor when your battery reaches a specified level. Kind of like powersave mode in settings.
You don't need to do anything to make it happen its all automated. By default it sets the governor to conservative and underclocks to 702000 then depending on whats installed it restarts virtuous_oc or changes back the governor to ondemand and the cpu back to stock (1188000).
These settings can be edited at:
/system/etc/init.d/74-virtuous for virtuous users
/system/etc/init.d/75-pcm for stock users
/system/etc/init.d/76-pcmapk for apk users (setcpu)
The lines are commented so editing should be easy enough in root explorer, if not lmk i will help out.
You will have to restart setcpu or whatever apk after your battery reaches the threshold. It works with setcpu, cpumaster, cputuner, and overclock widget.
Once you battery gets above the threshold it will restart virtuous oc or change the gov and cpu freq to whatever you specify in the script. It checks the battery level every minute.
The virtuous oc attachment includes virtuous oc this can be flashed right over my flashable oc daemon. It can be used with roms that include virtuous oc as well.
Download the zip you need:
Virtuous_OC-PCM = Virtuous_OC and PCM
PCM = PCM Stand alone Auto sets default cpu frequency use without setcpu or virtuous
PCMAPK = PCM for use with some apk's that control cpu (setcpu)
Please report any bugs here.
How to edit settings:
This is virtuous_oc version but they are all about the same.
Edit the lines in red to adjust settings, this is labeled actual script will look a little different.
Code:
#!/system/bin/sh
#PowerSave CPU Manager Virtuous
#smokin1337
SLEEP=60
(
while : ; do
#Powersave Threshold Default-25
CAP=[color=red]25[/color] [color=blue]<<-- This is the battery percent where the powersave settings will be applied, change the number in red.[/color]
LEVEL=`cat /sys/class/power_supply/battery/capacity`
if [ "$LEVEL" -lt "$CAP" ]; then
pkill virtuous_oc
#Powersave Governor
echo [color=red]conservative[/color] > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor [color=blue]<<-- Edit this to the governor you want it to be set to in powersave mode. ie. powersave, conservative, ondemand, userspace, etc.[/color]
#Powersave CPU Frequency
echo [color=red]702000[/color] > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq [color=blue]<<-- Edit this to set the cpu frequency for powersave mode ie. underclock. [/color]
else
/system/xbin/virtuous_oc
fi
sleep $SLEEP
done
) &
In the stand alone version (75-pcm) there is also a setting for your default governor when not in powersave. This will be your default setting.
Your rom MUST support init.d, this is a script.
Thank you!
I will try it now.
Does this work with the kernel in the 2.08.651.2 release?
Is this a Terminal-based app or an actual app? If Terminal, what command invokes it?
Also, you say whatever CPU management tool we use doesn't matter, does that also mean I can just toss SetCPU altogether?
Yes it works with the new kernel. It gets installed to init.d so it runs by itself when you boot the phone. You dont need to run it in a terminal.
It works with setcpu, you need the pcmapk version. What it does is shutdown setcpu when your battery gets low and underclocks your cpu to save battery. You just have to run setcpu again when your battery gets charged.
I'm interested in this mod but I don't understand what i have to do. Do I download all 3? I don't want to use any apk. to help. Do any of those downloads manage everything alone. PLEASE HELP...thank you and sorry for the noob ???s.

Yes the PCM-signed.zip will manage it without any apk or virtuous oc. Just flash it as is. Sorry about the explanation of it i didnt know how far to go.
Wow...thanks for the quick response. Thank you for your work.
not trying to be a **** here but whats the point of this being used with setcpu since setcpu seems to already do what you are describing here. profiles set up right will underclock and change govenor when battery gets to level X.
Now for the others it seems to be helpful for those that like profiles being used.
Honestly i havent used setcpu. But your right it works well by itself, and really good with virtuous oc. I use it personally with virtuous oc and it helps alot saving juice.
Gonna try this out. I don't want to overclock, I just want to underclock in order to save juice.
Please help me understand it a little more, I already use virtuous oc, I've been running the pcm version with virtuous oc the last dew days and notice a huge lag when phone reaches 20%, how can i give it a bit more juice? I think whatever you set it to when battery is low is too slow..
How does virtuous oc work together with pcm?
Also is the version for the virtuous OC-PCM in this thread the same as in the other thread (virtuous OC thread)?

Download the uninstaller file in the thread related to it. But by now im pretty sure you fixed it. Is it stable yet?
Edit: This is stable but it doesn't save juice and my OC isn't completely stable.
Although some parts can be considered as original, all are based on inspirations, examples and other people's code.
I have no claim to be original. I am only trying to make my (and probably other's) SGS2 experience better and fun.
I do this for fun. so, if you just want to argue with me please don't. use the energy coming from your youth in something useful.

Who Should NOT Use This Kernel?
If you are going to use very low voltage settings and complain about having lockups, you SHOULD NEVER use this kernel... just run away! This kernel is just as stable as the stock kernel if you do not modify any settings. Do not blame the kernel if you change the voltage or clock settings. If you do so I will blame your stupidity. I will not remove any feature just because some dumb users select wrong settings. If you are a rookie with an uncontrollable instinct of modifying advanced settings please use speedmod or stock kernel.
This kernel generally contain some experimental code and some of them may be even undocumented. I have different release strategy. I always use the latest version and if I notice any problem I try to fix it. However, I do not use all the features of the phone. So, if you notice any problem please report it. bug reports are welcomed, whining is not.
If you judge a kernel by quadrant score, please, I beg you, don't use this kernel. I don't have enough time nor motivation to answer your questions... Some people got 8000+ quadrant (search the thread) and there is no way you can beat them anyway.. so, go away...
If you are one of those who judges a kernel while sleeping ("oh my god!! lost %1 during sleep"-guy) please use another kernel, sleep and never wake up. it will maximize your battery and minimize the tension in the thread.
If you still believe in battery calibration, discuss it in some thread else. we respect all religions but missionary acts are not welcomed in this thread.
99.9% of the code belong to others. I have some modifications and/or additions to the kernel as C code or scripts but they are so little compared to the original code base. If you think you are better developer than I am, don't waste your time (and mine) as I accept it beforehand so please just go away.
FAQ
Q: Does this kernel support Samsung's ICS leak, CM9 or any ICS edition?
A: No, it does not.
Q: Does this kernel support latest Samsung i9100 ROM?
A: Yes, it does. Unless otherwise stated, you can use this kernel on latest Samsung ROMs (official and leaks). it is tested on 2.3.4, 2.3.5, 2.3.6.
Q: Can I use this kernel on I9100G?
A: No, you cannot. Only european i9100 models are supported. Also, I compile ntt-docomo version for each release but beta versions do not support gps and digital tv on ntt-docomo devices.
Q: Does this kernel support CM7 or any other AOSP based roms?
A: Yes, but it only support cm7 or miui based roms for now. If you are using another aosp based Rom tell me and I will support it.
Q: Can I use app protectors with this kernel?
A: Yes, you can. Android logger is enabled by default.
Q: Some custom lockscreens or protectors do not work with this kernel. Can you fix it?
A: see the question above.
Q: What is smartassV2 governor?
A: It is a governor to control CPU frequency. This governor has a built-in "profile" similar to SetCPU but the profile has no upper frequency limit. It tends to stay on lower frequencies when the screen is off and scale up very slowly, so screen off will use lower clock rate thus conserve more battery, but it also has a fast wake up feature so that user interaction will not see the lag when switching from Sleep to Wake state.... (So SetCPU Profiles are sorta redundant when using this governor, you can still use SetCPU to OC to higher than default Clock frequency).
Q: What is the best UV settings?
A: There is nothing as best UV settings. You have to find the best settings for your device for yourself. Start by decreasing 25mV on each freq and decrease it every day until your device becomes unstable.
Q: What can I do to have the best battery life ever?
A: put your phone into airplane mode. if you don't like to do it read the guide below.
Q: Which roms are supported?
A: All android 2.3.4 and 2.3.5 roms are supported. Try the latest version. if you have any problems leave a post to this forum and ask for help.
Q: I get random reboots or freezes. What should I do?
A: Before reporting any problems you have to make sure that you are using stock voltage values. Some phones cannot handle undervolting. Secondly, you have to give details. When did it happen, which rom are you using, can you reproduce it, do you have any custom init scripts which changes kernel parameters such as freq voltage or anything else?
Q: do I need to recalibrate the battery?
A: You don't need to calibrate battery for SGS2. Thanks to Entropy512 to pointing out that our device uses MAX17042 which is specifically designed not to require calibration.
Q: do I need to perform any wipe?
A: no. you don't have to wipe anything. however, try wiping cache and dalvik cache if you have any force closes or any other issues before reporting the issue.
Q: Is the battery life better/worse?
A: maybe... you'll never know if you don't try... People are reporting that they are having the best battery but it may not be the case for your device.
Q: where is the interface to change GPU clock and voltage?
A: There is no GUI (graphical user interface). the interface is used via device files. you have to use init.d scripts to adjust the values. there are some examples in the first post about how to use init.d scripts and gpu voltage/clock interface.
Q: Which governor is the best? Which I/O scheduler is the best?
A: You have to try them and select the one you like. There is a very good explanation about governors and i/o schedulers here: http://forum.xda-developers.com/showthread.php?t=1242323
Q: My phone doesn't go into deep sleep mode. Why?
A: try to clear cache and dalvik cache by using CWM recovery and make sure that your phone is not connected to a charger. it does not go into deep sleep when it is charging.
Q: Which version is the best?
A: supposedly, the latest version is the best. But if the latest version is beta there may be unstable code in it. testing the beta version and reporting bugs will help me. but it's your choice... try and see... maybe this kernel is not stable for your device at all, who knows... I will not answer any "what is the best?" questions and I kindly ask you not to ask that kind of questions since there is no answer to that.
Q: How does the automatic battery calibration work?
A: Automatic battery calibration feature is removed as it was useless for SGS2.
Q: What is an init.d script?
A:init.d scripts are the scripts which are executed during the boot time. actually, they are meant to initialize and deinitialize system daemons and manage some startup/shutdown tasks. but in android world they are just "autoexec.bat"s. so, it is a mix of rc.d and init.d directories in linux distros. everything in /system/etc/init.d are executed during the booting process. since it is not standard in every android device,some developers choose to execute files starting with "S" and some execute everything. in this kernel, everything in /system/etc/init.d is executed. you can create a script to change, lets say, voltages, schedulers, apply tweaks, run overclocking daemon or run anything else you can imagine.
Q: My phone doesn't go into deep sleep. What is wrong?
A: Make sure that you have cleared cache and dalvik-cache after you install the kernel. Also, reboot once more after the flashing. the phone doesn't go into deep sleep if it is connected to a charger or to a computer. There may be an application running in the background which is preventing deep sleep. In that case you can check which app causing the problem with "BetterBatteryStats" application (search in Google).
Q: I want more info about CPU governors.
A: There is a great post about cpu governors (thanks to droidphile): http://forum.xda-developers.com/showpost.php?p=19339524&postcount=10023
If you still want more info, try them by yourself.
Q: Can I use this kernel with I9100T?
A: Yes, you can. the only difference between I9100 and I9100T is that they have different SAR values.
quick and dirty guide to have less battery drain:
- use 2G-only if you don't need 3G
- monitor programs which cause wake-lock. use betterbatterystats and either uninstall or tweak them
- do not use task killers. see the previous item and find the malicious programs instead of repeatedly killing them.
- do not activate google latitude on maps.
- if you don't need pushmail, uncheck gmail sync and use k-9 mail to pull mail, lets say, every 1 hour or so.
- go to settings / location and security. disable "use wireless networks" and "use gps satellites". enable them when you need them, other than that keep them disabled.
- disabling auto-brightness and using a low brightness level helps. do you know that you can adjust the brightness by swiping your finger across the notification bar? try it...
- using juicedefender may help, but it may also cause more drain. test it yourself.
- if you need more speed than 2.5G (i.e. edge) disable HSDPA (*#301279#, select 2 then select 1). you will have 3G instead of H(SDPA) and I think it is fast enough
- disable fast dormancy. dial *#9900# and disable.
- disable auto sign in for google talk (search for talk in appdrawer and use settings to disable automatic sign in)
- disable samsung update and don't use samsung gadgets if you are not in love with them. (this part may be taken care of the rom developers)
- try several radios. I recommend you to try KE7, KG2 and KH3 and choose the one which suits you best. KG2 seems to be the best for me. however, in terms of battery life, there is not much difference between those three.
- be aware that more you use your phone more the battery drains don't complain like "my battery drains quite fast but I did not use my phone. I only played angry birds for hours without making a single call" or don't expect to have a decent battery life if you use your phone as a computer or download torrents using your phone.
i think i will wait 4 feedback because it's based on u2 source.
But good job anyway
cheers

yes, I know that is why I have asked for patience in OP. If the moderators were a bit more patient maybe I would be using some other kernel and wouldn't bother to compile my own
I've uploaded the recompiled kernel. enjoy.

you have to try.
smartassv2 governor with 200-1200mhz setting is very satisfying and the battery lasts at least as long as speedmod-v27 for me.
bfq scheduler maybe
..........will u add it in the next release?
CFQ scheduler really drain too much power.....

power drain change is not noticable though.
Did you get better battery life than REGEmod-U1?

I haven't tested it, but theoretically smartassv2 governor that I am using in the kernel should give better battery life than ondemand with a little (not even noticable) sacrifice of performance. you don't need to use any setcpu profiles with smartass governors.
test it. it may or may not give better battery life for you.
I will. Thank you.

great work
i have searched and re-searched a lot of times for threads that talk about my same problem, but none of them is related to it in terms of phone, kernel or ROM, and they're all nearly 2 years old
in addition, i am new to this forum, so please don't shoot me
anyway here it is:
i've tried almost every existing method to get governors like smartassV2 and interactive (my favorites) to stick without reverting to ondemand, but none worked
i noticed this:
in the exact moment the screen is locked, something sets the governor to ondemand
in the exact moment the screen is UNlocked, the same thing (i guess) sets it to performance, then to ondemand
since i know a bit about intents and receivers, i can say this behavior is triggered by android.intent.action.SCREEN_OFF/ON intents, so there must be some system apk with a receiver for those which reacts and changes governor accordingly
right now i'm running a modded init.qcom.post_boot.sh that sets back the governor to a custom one (i.e. smartassV2) every 20 seconds, which is the only way i can get it to "stick", however i hate this method 'cause it implies there is a shell running in the background, thus stealing some (yet minimal) resources and battery, and the problem is still there
some info that might come in handy:
phone: Acer Liquid Glow E330
ROM: Glowing Liquid 1.5.2 (ICS)
kernel: Lupo's kernel V3
take a look at the logcat screenshot attached, i think i found something but i have no idea what to do
EDIT: if you can't read what's in the pic, it's saying something about a CpuGovernorService
how is it possible that nobody cares? i've given more info than anyone else on this problem people, experts, devs, anyone, say sumthin'
Maybe try tot set it with an app like trickster mod and set it on boot? Or try another ROM to see if its a system app. Sorry I dont really know the programming part..

i'll disable my script and give it a shot, however there is no other ROM, only two existing alternatives are stock (which only has crappy ondemand) and glowing liquid by vache
EDIT: didn't work dammit
UPDATE: by raising the log level to 7 in a custom boot.img i can now see PrintK saying this:
cpu_policy->user_policy.governor name interactive, str_governor = ondemand
update_cpufreq_governor cpufreq_update_policy return = 0
as a linux user, i know that PrintK is basically the kernel talking to the user/log daemon, so i am now asking help to kernel developers for any clues about it, and maybe how to change that parameter (or whatever it is) in the kernel to get rid of ondemand
as difficult as this can be to figure out, i'm sure that this would be the end to many headaches, so anyone who knows about how linux kernels work please help me find the solution to this thing
Alright, i give up, ain't no answers here
Somebody close/delete this goddamned thread, please

If you look closely, it resets to ondemand every time the screen changes state

EDIT: the thing is, i do have a cpu tuner with wake/sleep profiles, i simply can't seem to have it doing its job
also i stick on stock kernel because the other ones have buffer problems with music, and i'm not sacrificing my flac files for
crappy mp3s

is it this one ? "CPU tuner (Rooted phones)" on play store , i give it a chance yesterday and it looks to do the job, more than nofrill etc .... no easy to set fine but if i see the log file 'journal' it works , i come back to "smartassV2" (wich is "virtuel" gov settings) after wake up and at enter calls ...

No, just the setcpu implementation in rom toolbox. anyway i tried that "cpu tuner" and it kept forcing the governor to ondemand despite the "normal" mode being set to interactive (and yes, "normal" was the current setting)

Hey, so basicly im running cm10,2 on my SIII and im just woundering what the best tweaks/mods are to improve battery life,
so far i have
install rom toolbox pro, and set the cpu profiles up as to lower cpu power as the battery drains
(confued as to what i/o scheluler i should use, and governor, i have done lots and reading but selectedi/o cfq and gov is pagasusk
plus under sysctl tweaks and govenor there are alot more setting, but im affraid to touch them as i dont want to become unstable
i also have greenefy and du battery saver i also have trustgo antivirus,
also if someone could help me, du battery saver have cpu lowering capabilys and if i was to use it with rom toolbox pro cpu profiles, would this conflict,
my kernel is 3.064-cm-g0a49c6d
and ive been looking at pimp my rom, app, but i dont know if its safe and benifishal,
sorry for spelling,
cheers jason
not sure if you're mentioning undervolting with "lowering cpu power" but if you're not you should try to undervolt your cpu
