[Q] SetCPU governors (explained)

The SetCPU website explains some governors: http://www.pokedev.com/setcpu/#7
However it seems that some extra governors, not covered by the SetCPU site, have been added to some kernels; which I think should be documented so users know which one to pick.
I will add responses as to what each governor does to this post. If there are any governors not explained that you've come across, please post and we'll see if somebody can explain it.
Unexplained governors (somebody please tell me what they do)
smartass (Best explanation i've found paraphrases to: based on interactive, but better.)
----
ondemand
Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see "up threshold" in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed. - SetCPU website
conservative
Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery. - SetCPU website
performance
Available in most kernels. It will keep the CPU running at the "max" set value at all times. This is a bit more efficient than simply setting "max" and "min" to the same value and using ondemand because the system will not waste resources scanning for the CPU load. This governor is recommended for stable benchmarking. - SetCPU website
powersave
Available in some kernels. It will keep the CPU running at the "min" set value at all times. - SetCPU website
userspace
A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor. - SetCPU website
Interactive
The 'interactive' governor has a different approach. Instead of sampling the cpu
at a specified rate, the governor will scale the cpu frequency up when coming
out of idle. When the cpu comes out of idle, a timer is configured to fire
within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer
fires then we assume the cpu is underpowered and ramp to MAX speed.
If the cpu was not 100% busy, then the governor evaluates the cpu load over the
last 'min_sample_rate' (default 50000 uS) to determine the cpu speed to ramp down
to. - [Patches] For developers, interactive governor patch for leo kernel

As explained by MDJ:
SMARTASS GOVERNOR - is based on the concept of the interactive governor.
I have always agreed that in theory the way interactive works - by taking over the idle loop - is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the "old" minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 245Mhz (or if your min frequency is higher than 245 - why?! - it will cap it to your min frequency). Lets take for example the 998/245 kernel, it will sleep at 245. No need for sleep profiles any more!

Thanks for this. Smartass has been a mystery to me.

When I installed SETCPU I selected auto-detect, now on my device (not a HD2, but this seemed like a good place to ask as it is directly related) now I have no way to select the governor at all (box is blank), how to I change the detection from automatic to a device type "Tegra 2" in my case, I see no option to allow me to do this?
Thanks,

Powersave
I read on this forum that Power save SetCPU governor saves the best battery. I Hope this is true?
I am trying to get my hands on powersave
I can't find powersave in the "market" though.. What's up with that? Can anyone tell me which one it is? Maybe give the name of the developer so i can find it back easier?

Yeah, that's not how it works. Governors are a part of the kernel. If you want features in your kernel that you don't have, you must flash a new kernel.
also, perhaps you should reread what 'powersave' is. It will keep your phone at the lowest cpu speed constantly. This will save battery, sure, but it will also completely destroy your phone's performance. Might as well go back to your old Moto Razr.

thx, actually, i set those gov randomly before i read this post

Ondemand vs. Smartass vs. Performance gov. - Test
The idea was, that maybe the display eats so much power,
that if it is on, the CPU setting does not make a big different.
Bottom line: it does.
Phone: HTC Sensation, Leedroid Sensational 3.1 (kernel 3.2)
Conditions: Simulating light cpu use like writing email:
Brightness 50% (no timeout), MP3 playing (Volume=1, headphone), a new document on the screen,
Wifi and 3G network off (these have fluctuation, so it is easier to compare if these are off)
Ondemand 192/1188 governor: 5 h 10 min
Performance governor: 4 h 20 min
SmartassV2 192/1188 governor: 5 h 2 min
Off course if the display is off, it is easy to choose, because there is no need for performance.
I set up Conservative 192/810, but any similar can work.
I choose Ondemand, and using "Tasker" to switch to Performance, if certain applications are active,
like Doodle Jump - which run a little smoother with the Performance, for as an example.

thanks for the info...

nice, thanks

Thanks, cleared my doubts.

completely noob question, how do u choose between governors? set cpu from the market its a paid app, and the one i downloades from the official post wont work

SetCPU best speed

Hey everyone, just wanted to post this to see what cpu speed works best for you guys.. Im using these preset things with the program like performance or power saver etc but i dont seem to notice a difference all of them seem to be the exact same.. Wondering how to make it good for like 50% power and 50% performance, basicly balancing the 2 out as long as its better than stalk and not burning out my cpu.. so thanks, let me know what works for you guys as ive heard its slightly different for everyone else
(HTC EVO 4G)

I use the standard "ondemand" governor with a 998max-245min, but the thing I found makes the most difference are the settings under "Advanced".
I use the below "Advanced" settings along with a 245-245 screen off profile.
Seems to get me the best battery and cpu scaling.
It also helps to use an undervolting kernel like Freedom-More.
Try that for a couple days.
NOTE: click the apply button a couple of times (might be bug but they sometimes don't take on 1 button click). Try them as is without "Set on Boot", until you are sure that your phone likes them. Plus, check after a reboot that you verify/reapply them.
Sampling rate: 20000
Up Threshold: 85
Ignore nice load: 0
Powersave Bias: 14

The "presets" are how the cpu scales i'd use "interactive" or "smartassv2" 245 min and max at 998+ then search around for here for various profile set-ups

I'm running the Gingerbread-Evo-Deck 1.3 with a Savaged Zen 2.2.1 CFS HAVS Kernel. I'm also undervolted 50mV, and using the interactive x governor set at 128MHz-768mhz. Running a few other simple tweaks learned from Carhauler, and I've got excellent battery life and great performance.

I currently run mine on an ICS rom & it comes standard with a tiatmat 4.1.0+ kernel & the cpu is running at about 245mhz-1036mhz with smartass governor(I usually set it to smartass v2 but it switches back to smartass haha). My battery life for me is enough to get me thru the day.

What governor is the best and max cpu frequency on SDSL REVO by miroslav ?

it depends on your CPU . every CPU has different quality: some cam go up to 900 mHz and some do freeze even at 806 mHz. Julst test it out but remember not to set the frequency at boot ^^
e.g i could go up to 880 mHz with .29 kernel (old mur4ik ROMs) for a few hours.
wih .32 kernel (PCFighter v5) 825 was the maximum
EDIT: smartass v2 is best governor for me

I Thought SmartassV2 was a battery saving governor ?
my quadrant score with REVO is always better on ondemand
@ 806mhz

for me smartass2 is best governor and my max cpu frequencu 729MHz, i use SDSL pre-Final, score in quadrant is 1259, and sometimes i oc it to 806MHz, then quadrant score is 1432, on same rom.

Smartassv2 is undoubtedly the best governor, my frecuencies are: min 245mhz and max 768mhz..
Antutu benchmark give me 1932

For me Smartassv2 is the best and my frequency is: min245 and max 806.

Smartassv2.
Min: 122
Max: 806

SmartassV2 with SIO, @122/600 daily use, Performance @245/852 for bench.
Freezes @ 864mhz

I use Smartassv2 min245 and max 729
It's the best for me, also best results with native freq.

Guys,
Everybody talks about "huge" Quadrant numbers...like >1400 points with similar settings I have.
I get 1060 points with SmartAssV2, CPU Min 245, MAX 729, JIT ON, CompCache OFF, VM size 32.
Can it mean that my CPU is "weaker" then others?
Thanks.

Every cpu is diferent, mine go max to 787 and give 1389 on quadrant, at 729 smartassv2 i get 1193 on quadrant.

yeah mines is getting very weak too i used to get to 1500 for quadrant but now its very low like yours no matter how i set it.......
my cpu can no longer score above 3000................ ZZZZZ OMG next signing of contract is in may OMG

SmartassV2 gives lower scores.
Try with Performance governor, 245/~800mhz,u'll get an higher score

just wondering, where can i get smartass v2? would like to try it, but cant find it. or is it in the cyanogenmod settings of the rom?

If you use performance it will always scale the highest possible eg 806 so it wastes very much battery

The CPU frequency depends on how much your chipset can handle ( mine can handle up to 806 Mhz with Alfs and 787 Mhz with nAa). for the governor select smartassv2 i think its the best

Undervolting the GT-N7000 for better Battery life

Hey there ,
so i wanted to share share my awsome Undervolting results with you
At first im running on Chasmodo's latest CM 10.1 i really appreciate his work ! I use the latest CM 10.1 Kernel.
With his rom and this voltages u find under this introduciton text i could get nearly a month with Standby time
(without doing anything , Wlan turned on , Data off) i attached a screenshot (29 Days and 5 Hours sorry for the German language)
Every day i plug my N7000 out from the Loading station its 5am on 3pm i lost 1%.
to change the Voltages i use SetCPU (full version)
1400 MHz
1200 mV (Stock: 1350mV)
1200 MHz
1100 mV (Stock: 1275mV)
1000 MHz
1000 mV (Stock: 1175mV)
800 MHz
925 mV (Stock: 1100mV)
500 MHz
900 mV (Stock 1000mV)
200 MHz
800 mV (Stock: 975mV)
So i dont know my Voltage group sorry guys , if this values are not working just go in 25mV steps lower from your stock voltage
until the CPU gets unstable or crashes than u know that u cant go lower just do this with every clocking !
I also used this voltages on XXLSC Ultimate Rom with the HydraCoreNirvana Kernel i had fantastic results too but not that good like i get with the Asylum CM 10.1.
PS: Just this Voltages wont give you very good Battery life if your Rom / Settings is/are eating your battery. If you get better results with
lower results (stable) just go ahead and post it but im sure this values are nearly the lowest stable u can get
Code:
Its [U]impossible [/U]to hard brick your device with Undervolting , you only could get a soft brick if you use (Set on Boot) and your voltages will crash your System after boot. thats easy to fix just after the phon booted up fast go into SuperSU and delete the root rights for your Undervolting tool.
Thanks for Reading and if i you liked this push the Thanks button =) !:victory:

Thanks man

I think you should say which Voltgroup (A, B or C) your note is. Because those freq are really low (I think too much low for my note, that's voltgroup B).
Do you remember which voltgroup has your note, when you installed hydracore kernel?

Better i would buy a spare battery rather than spoiling my devices performance. We arr not in 1000BC with no electricity. Sure every one can charge a spare and can switch it.

It's a feature of the hydracore kernel only I think, because its read a particular value (something about mainboard and/or cpu) and the kernel automatically apply dedicated undevolt values. You could see it in system information, where hydracore kernel is detected. Without it, I think you can't do anything :/
Anyway, sincerely I remember some time ago I tried to lower my already undervolted cpu voltages, and I got freezes. I will try to go lower a bit, hoping it will works. A very important thing, is not only the lower battery drain, but also the lower cpu temps.

I bought rom toolbox full sometime ago, when there was sales. If I remember correctly, there is a section relative to the cpu control, but I don't remember if it was undervolting capable also. You should start to search it from there (I'm sorry, I don't have the app installed anymore, so I can't help you properly... In case, use voltage control app)

I don't know - I am not sure if Undervolting could hard-brick or damage the hardware but back then running GB roms I had undervolted FM Kernel and there was trrrr trrr trrr like sound from my Note.
Be careful.

never had any problems and just logical cpus could brick if you give them too mutch voltage , if you give them less voltage the system only can crash your sound could have been beacuse it crashed so really u cant hard brick your device with undervolting ... maybe a softbrick if your unstable voltage settings are on autostart.

Hey there , you cant uv with Philz kernel just read his thread check his FAQ there hes writing that hes not supporting
oc/uv its just a repacked stock kernel
use HydraCoreNirvana but when you download the kernel check that its the OC version if not than you cant change your voltage like with Philz kernel.

You can you can
Just use tegrak ultimate Overclock app. I bought it because I think it's the only who give you the possibility to Undervolt the gpu also. Initially, philz kernel wasn't supported, but now it is. I undervolted my cpu setting the values that I had using the hydracore kernel oc. And today I lowered them of another - 25mV also. Everything works nicely until now

Better i would buy a spare battery rather than spoiling my devices performance. We arr not in 1000BC with no electricity. Sure every one can charge a spare and can switch it.

Nice attitude you are showing there. Oh, there is plenty of power, let's waste.it! Really, that kind off attitude is definitely going to make the world a better place
What's more why do you think undervolting does influence the performance? It only influences the power consumtion and if you go too far it does render the phone unstable. But it certainly does not in-, or decrease the cpu's performance.

Yep tegrak definitely does the trick with PhilZ kernels. I have been using it for at least 8 months now and my phone is undervolted too. Only the highest cpu state is overvolted because I overclocked it to 1552 MHz instead of 1400.

I would love this kernel under ubls4 if it has a proper exfat support. Until this is not fixed like philz kernel, I can not test or try

Please explain why you overvolted AND overclocked the highest cpu state. Doesn't this shorten your batteries performance?

Did you changed cpu governor or something else (like screen off profile to reduce CPU) to achieve 1% battery loss at 3pm?
And was that with mobile data on?

I overcloked the highest cpu state from 1400 Mhz to 1552 Mhz because I want more performance. And because my phone became unstable with the 1552 Mhz and the standard voltage. So now my phone saves energy when the lower cpu states are active and it has a bit of extra power at the expense of battery life when it needs the most processing power. All in all that gives me better battery life than with stock settings and a snappier device when needed. For me this is the ideal solution.
