I'm using emanoN V4 with No-Frills, and since CM7.1 with SetCPU, I always used 'ondemand' as Governor.
But reading other posts on other devices forums about this, some people say SmartassV2 is the best...
So, as each device is different (specially by the ARM version and manufacturer), I decided to begin this conversation here, and listen to what people with the same device as me has to say about it.
So which Governor do you consider the best for SGM?
Im using cm7.2, setting at nofrilis Governor : SavagedZen io : sio and undervolt at cm setting, give more battery life.

Thanks for the reply, but as I can see on No-Frills, sio is th I/O Scheduler, that is already set. I'm asking here about the Governor.
Ondemand and set noop
Sent from my GT-S5570 using xda premium
on emanonV4 i use Smartassv2 nd i/o noop
I see that people are very divided between ondemand and SmartassV2.
Now with sio and noop as I/O Scheduler.
Anyone else would like to share?
i will say ondemand because cpu will be set at lowest frequency and when you need it it will set at higher frquency which will save your battery and if you want performance then no lag will be good
The principle of the ondemand governor I'd already figured out (and actually didn't like it, very rough).
I would like to hear more about the principle of the SmartassV2, whereas since this morning I'm using SmartassV2 + noop and I noticed my SGM way smoother than with ondemand + sio.
Now is wait and see if the battery is sucked more.

smartassV2 is a re-working of the original smartass governor, it allows for the CPU to scale through all frequencies from the lowest you set to the highest, based on the load occuring. Basically it scales CPU based on realtime needs of the system, saV2 supposedly incorporates some more agressive settings for screen off, and I believe quicker scaling than the original smartass.

Thanks a lot, man! And now I think that I had made my choice:
Governor: SmartassV2
I/O Scheduler: noop
Highly recommended!
Hey guys,
I know the HTC One has a few cpu governors like msm-dcvs, intellidemand, ondemand etc... and gpu governors like ondemand, simple and interactive... and I know there's a thread that explains each governor, but what are the differences between each governor in relation to the HTC One, and which would you recommend for a nice balance of battery and performance? and what are the limitations of each one? Thanks a bunch!
This is the thread you're talking for...
However, the difference is how the governor work.
And the chose of the governor depends about your use of the phone...
There is still no answer about GPU governors. Aswell as specific settings in every governor which can we set
Is there any way to overclock this device's cpu or gpu or even change governors?

AFAIK, the power plan modifies the cpu frequency stepping, but still it doesn't allow surpassing the maximum CPU frequency of 1795 MHz.
And the only governor in our kernel is a version of hotplug.
Here's how it works in my understanding:
Quote: The “hotplug” governor scales CPU frequency based on load, similar to “ondemand”. It scales up to the highest frequency when “up_threshold” is crossed and scales down one frequency at a time when “down_threshold” is crossed.
The powerplan can modify the up- and down- threshold steps (so the device can use max frequency sooner and stay on higher frequencies longer), but that doesn't affect max frequency at all.
Hi!
This scripts is not overclock, but change/lock clock speed.
You need root, and any Script runner app.
Ddr_gpu=lock max speed ddr and gpu
ddr_gpu_cpu=lock max speed ddr, gpu and cpu
ddr_gpu_cpu_4core=lock max speed ddr, gpu, cpu and lock 4 core cpu
ddr_gpu_cpu_core_4core_stock=revert all to stock.
This scripts not pernement, if you restart the phone, all settings revert back to stock.
Ps: please when you download this files, delete the .zip.

Won't allow overclocking max frequency either... Just increasing min freq, and decreasing max freq.
Pretty much useless on P7, since we only have 1 governor and 3 I/O schedulers to chose from.

Hello guys..Now how we have a lot of new kernel, in yours opinion which is best setup for performance,battery in governor, sheduler ,min&max Cpu,Gpu etc for our MI3 ? For now I use interactive,noop ,min 300 MHz and max 1,2 MHz..Gpu max 462MHz.. And that's seems ok for me..and franco kernel by audahadi

Actually I can't...cuz I have no idea!
If you read the original post I linked, my aim was to increase battery life, so I just reduced all clock speeds while maintaining the default order
MaxFreq>SyncThreshold>InputFreq>MinFreq
But it gave me awesome results (again, check the link in prev post) without causing any lags, and ppl were asking for my setup, so I shared it with you guys.
Hope it helps you too :good:

okay let me explain then it used to increase the max cpu clock speed if needed, like if you've clocked your cpu at 1.5 and the cpu gets exhausted with 100% usage then the cpu will be increased to given SyncThreshold value for sometime to lower the pressure on cpu,, in simple words it should not be lower than the max cpu Freq. and preferably disabling it is a better option.. and btw your settings are just awesome phone is not over heating also and thanks.

Kernel by Gnome :thumbup:
Sent from my MI 3W using XDA Free mobile app
I don't know if it works on OOS versions but it does, on the OB12. You need to be rooted to be doing this.
Lower the input boost to 1036 on the big and 556 on the small first. Now, change the governor of the big cluster to conservative and the small to ondemand or conservative , benefit!
To see the improvement in FPS, you need to go to developer options and switch on profile GPU rendering. For those who didn't understand this: lower the graph is, higher the fps. Hit thanks if helped
Where to change these settings?
Any kernel manager would do. I'd recommend kernel aduitor

You'll see input boost in the bottom section of CPU in kernel adiutor. Core 1- 1036, core 3 -556 is what you've to do. It'll be 1324 default on both. I'm suggesting that for slightly better battery life

Lower SOTs are obvious, but to what degree is what matters. As far as I see, it's not that much.
GUYS, I recommend not to use this anymore. Oneplus has a reason to not release the kernel with conservative on . This is because conservative is not optimized for battery while interactive is. If interactive weren't optimized for battery, it'd be better than conservative for sure. I get only 4 hr sot on conservative but 5.5 on interactive. Though this is not placebo, it has a negative impact on SOT .
When I change big cluster to conservative, those cores will always stay above 2 GHz, as shown in Kernel Adiutor.

Good you realised that.. I did a little investigation on your tweak.. Apparently setting governor to conservative locks the frequency of big cluster to max possible, usually above 2 ghz and it will step down slowly ( by slow I mean really slow like 1-2 seconds). Thus causes you to have very less render times on gpu profile as shown in the xda portal post.. I opened up ex kernel manager and observed same freq in higher range.
After some time I just changed governor to interactive and changed minimum freq of big cluster to 2 ghz.. I observed the same render times as situation as time when conservative was set as governor...
So this tweak is nothing but type of placebo since ramping up freq can lead to faster processing
Edit.: Couple of people on xda portal have said the same.. I didn't check it..
