"No-Frills CPU control/Pimp my Rom" for different speed governors and I/O schedulers

"No-Frills CPU control/Pimp my Rom" for different speed governors and I/O schedulers
The custom Kernel for A110 is coming. But till then, you can try out some different clock settings to get you more speed when on games and experiment with speed governors and I/O schedulers with the stock kernel.
Install No-frills CPU control or use Pimp my ROM to change the Min clock(limited to 250 MHz) or Max clock (limited to 1.001 Ghz now) and 5 governors (ondemand, userspace, powersave, hybrid, performance). For optimal battery and speed use ondemand with 1Ghz/250Mhz and noop scheduler. For games, try performance governor. Those who want maximum battery life can try powersave governor....

I think you have not read the post correctly. See the heading...Its not for changing clock speeds...Its for changing governors and I/O schedulers and there is no way you can do that on stock ROM without an external application as there is no settings for that in the stock ROM. And I am not taking anything about overclocking dude And many of the end users are beginners who do not even know these things...
I have clearly mentioned that the highest freq is capped. And it is not useless. We can play with the governors and the I/O schedulers. Read before you comment pal

but all are useless in stock kernel.ask varun if u have any doubt.

You are totally wrong dude..Get your info right. I have been playing with android right from 2010 and have used a multitude of phones Am not a beginner...I do not have to ask Varun on this...Default kernels come with limited speed governors and I/O schedulers that I have listed above, and THEY DO WORK...When you modify the kernel using sources, you can add many more governors and schedulers and also add other functionalities like over-clocking. Think before you post pal
http://forum.xda-developers.com/showthread.php?t=1369817
Read this dude....
And for your knowledge. The default governor and scheduler that our A110 comes set with is hybrid/cfq. That gives the maximum quandrant score of 3000 and above. Try to change it and you will see the difference in performance. The quadrant scores will go down. The settings DO WORK and to get better battery you can compromise on the performance.
Cheers....

m also not new in android..i also used too many android phones.

You mallu?
same here, expand what you are trying to say?
o/c not possible in stock kernel, but yes we can set clock values depending on the stock clock values between 0 - 1ghz (min 250mhz / maxx 1ghz), and even set governers, we need root for doing such actions na? but not possible without root!!!

so can you give me a clean explanation of everything u said on the 1st post?

Yup..plz explain dude.:angel:

in the stock rom/kernel , what settings in "no frills cpu control" is the best for performance and battery respectively ?
the options seen are governors ( userspace , ondemand,hybrid, powersave , performance ) and I/O scedulers (cfq , deadline, noop) ..
will changing these options be effective in the stock kernel ?

[KERNEL][TouchWiz] TerraBuzz [22 May][PR2.7][STweak][OC/UV][CPU/GPU/MDNIE]

Hello,
Let me introduce a kernel that I've been using every day. Despite the name which is me, the actual developer of this kernel is aatjitra, so please thank him. Since he is using N7105 and for ease of reports, we decided to make a separate thread for the International Samsung Galaxy Note II GT-N7100 model. So it is me that will maintain this thread for N7100. Of course with the help of him to answer questions.
For GT-N7105 model, please visit the original thread here
* WARNING *​This kernel is only for stock ROM or TW Based custom ROM!​DWYOR - Do With Your Own Risk!!!​​
TerraBuzz kernel is created for Samsung Galaxy Note 2 that will suits daily usage. There is no cutting edge and fancy development for this kernel as it's made as close as stock kernel based on source code provided by Samsung. Only cherrypick modification/enhancement from other developers to be implemented in this kernel. This kernel is fast, stable, and battery friendly. All tweaks and modifications are carefully tested to ensure great performance without compromising Galaxy Note II standard features.
Some unnecessary debug and log is also removed to make this kernel as light as possible.

Smooth and battery friendly
Installation
You have to be rooted
Install it using your preferred custom recovery
Reboot the phone
Enjoy the smoothness!
If you're coming from previous version (ex: PR2.5 and up):
- Open STweak and go to 'Extras' and tap 'Reset settings to default'. The apps will close by itself and let it be.
- Open Root Explorer or any file explorer with root access, go to folder /data and delete the folder .terratweak
- Download kernel that match your device type and save it to internal/external storage card on your phone.
- Flash the kernel via TWRP or CWM.
- Reboot and let it stay for a while or until the icon 'checking sd card for error' is gone.
- Open STweak and now you will see a control tab for SCREEN

Screenshots
Here are some screenshots collected from some of our users in the development of this kernel using various ROMs. Please use it as reference only, actual experience and results may differ.

TerraBuzzQ CPU Governor (Suspended)
I tried a few CPU governor which can suit my preferences that will turn off CPU core if the load is light to save battery.
And I come to LulzactiveQ by Tegrak that initially I think this is suitable for me. Nobody is using this governor for Note 2 and I dare myself to try it on my own.
Later on, I modified the source code for LulzactiveQ to remove some parts that I don't need and create my own logic for this cpu governor.
There are 3 thresholds for CPU load:
High Threshold = 100%
Up Threshold = 60%
Down Threshold = 30%
If CPU load = High Threshold (CPU Load = 100%)
CPU scaling per 200 MHz until it reaches maximum frequency 1600 MHz.
If Up Threshold < CPU Load <= High Threshold (CPU Load between 61% and 99%)
CPU scaling per 100 MHz until it reaches 1400 MHz and stop at that point.
If Down Threshold < CPU Load < Up Threshold (CPU Load between 31% and 60%)
CPU scaling per 100 MHz until it reaches 1200 MHz and stop at that point.
If CPU Load <= Down Threshold (CPU Load less than 30%)
CPU down to lowest frequency 200 MHz.​
By this logic, TerraBuzzQ Governor suits my daily usage pattern and tested by beta tester team. The result is great battery life and no lag encounter in heavy game such as Real Racing 3.​

Finally, it's available in XDA...
Best kernel i've tried so far.. Battery friendly yet very smooth...

Best Custom Kernel Setting

Hi guys please post your custom kernel setting with highly battery life and cool temperature

fateh3ro said:

CPU governor - intelliactive
Disable MP decision and enable Intelli-Plug
Set multicore power saving to 2
I/O scheduler - cfq
If you don't want high graphics then reduce the GPU frequency and similarly if you don't want smoothness them reduce CPU frequency
I personally don't advise settings CPU profiles as they make the phone lag a lot!
Hit thanks if it helped!

Yeah deep sleep is fixed, in the other kernel it did not go into deep sleep which was where the battery drained.

So when will it be completed? (And if it is completed, when can we download?) I'm itching to test it out.

So how high does the GPU overclock to? And where can I go to change the frequency? Can I use trickstermod app?
BTW, its a pretty good kernel. Nice and smooth. Ever better when I use Seeder. Only thing I noticed was that it reboots every time I try to overclock it to 1747Mhz. 1500Mhz is the most stable for me so I'm sticking with it for now. Keep up the good work!!

ive not added the option to set your own gpu overclock yet, but it will be implemented in a future release thankyou!

Thanks a lot. Very stable and fast so far. I couldn't install double tap to wake. Your old kernel supports this right? Or did I use it elsewhere? Sorry been flashing lots of ROMs lately.
**seems my kindle can't handle a high oc for even short bursts. I set it to 1747 and 10 seconds later it went to bootloop. Shutting it down manually then restarting didn't work. Had to reboot in recovery. But I don't pretend to know precisely what I'm doing.
Have you or anyone else tested above 1500? And if it's working could you share the exact settings? Thanks.

Highest I can go to is 1632. No hiccups so far. Using Interactive Governer with Min Frequency set at 1200Mhz. At the moment I am testing out the new I/O Scheduler that was added, sioplus.

That's what I was doing except with a lower min value and it crashed. Not the system just the browser this time. I'm thinking not all kfhds are created equally.
Overall this has been pretty stable though when I keep it at or below 1500

This doesn't support double tap to wake as it stopped the device from going into deep sleep which caused the huge battery drain, sorry about that.
And yeah I usually stay at 1500, but the option is there for kindles that can handle higher

Not sure if this is related to kernel or ROM (beanstalk) but I'm getting incompatible a lot in play store. I tried market helper but apparently its not ready for lollipop yet. Is there a workaround or like I just considered now--lots of the apps aren't compatible with 5?

Yeah its because a lot of apps don't support lollipop, however most of them can be downloaded from your browser with a quick google search

I know this is way out there a year later, but any plan on updating to 5.1.1 CM based?

What app do I use to tune this kernel?
I highly recommend Kernel Adiutor. It's free, open-source and is on the Google Playstore.
When will feature xyz be added?
I'll add it if I think everyone will benefit from this change, and that also means that I must find this feature to be useful.
Donations
While I am glad people want to help with the development through donations, I am generally opposed to accepting any form of donation.
Microphone not working?
Make sure the microphone gains in the sound section of KA is > 0. Alternatively, ensure that apply on boot has been unticked.
How do I use intellithermal?
In the CPU hotplug tab in KA, disable the two sliders underneath the slider for intellithermal. Then you may switch on intellithermal.
How can I help with development?
If you see or encounter any issues, let me know on github or on an XDA post. If you want to help develop, you can easily fork this project on github, add your own changes, then submit a pull request.

I'm back into kernel development after taking a long break since maintaining Dorimanx kernel for the S5. :highfive:
I've just released my first build (v1) which I've tested for some time now. Please let me know if there are any issues with the usual bug report format (dmesg + logcat + description of issue).
I just like a give another special thanks to @sunilpaulmathew for allowing me to use his kernel as base and for being open to the opensource community
Enjoy

Good to see you back to Kernel development... :good:
It will be a good deal for our S5 users
and hope you will still be active in my thread...

I'll try it, I just want perf fixes

Further testing has reveal that Faux sound control values don't stick after setting them in KA. This issue will be resolved in the next build.

If you mean the performance issues with Smartpack + RR, then yes. However, it will take some tweaking it get it "buttery smooth".

I guess you mean internal IO scheduler? Works fine on my end. Maybe reflash kernel or try one of the modded KA apps.
As for faux sound control and V4A, I think you can have both, as long as you don't tune the values for faux sound (which BTW is broken until the next release).

Internal I/O is missing from menu's, kernel clearly is flashed
good to know

Odd, I would imagine it would be an issue with KA unable to detect the paths required for IO tuning. Maybe problems with permissions? Any logs because I'm running out of ideas...

@Saber and @GeTex Can you please post your recommended settings? Battery is more important to me than performance. Would appreciate it very much.

There's many ways to go about it, I cannot comment immediately and I'd rather work with @Saber first on a good configuration but so far I can recommend this
Change CPU gov to ondemandplus
Change CPU hotplug to intelliplug, change hytersis value to 4, change screen of freq to 10xx MHz, use profile balanced and touch boost on
Change internal I/O to sio or sioplus, readahead to 1024, external I/O to noop and readahead 2048, change swappiness to 30 and vfs cache pressure to 130, or keep 100 for neligable benefits, turn on KSM with an interval of 1000 or 500 for slightly better performance at cost of minor battery, make sure Zram is set to 420mb or less. Turn off the thermal drivers and use intellithermal on defaults
With a brand new battery I have 4hr10 screentime and 1d standby, that is with alot of background stuff such as 20 minute GPS pings and weather updates, wifi and data and GPS always on
Battery life isn't up to date yet, will need to test a few more days

I was previously using these settings. Do any of these still apply? Thanks
Cpu governor: nightmare
Cpuhotplug: intelliplug
Touchboost: on
Cpu threshold: 1250
Thermal: intellithermal on, vdd and corecontrol off
Gpu: adreno idler
I/o scheduler: zen
Sleep between scans: 1000ms
Power suspend mode: autosleep
Fast charge on
Fsync On

No adreno idler in this kernel. Best to use power suspend mode hybrid for better battery life (uses display state + kernel sleep).
Edit: Also no UKSM. You can enable KSM if you like, but I personally don't need it.

Please read my second post. Main goal of my profile is good battery + performance balance without that "lag" in RR. Change around the profile if you like to suit your taste (e.g. zzmoove instead of ondemandplus).

Is following your suggested settings plus what @GeTex recommended doing too much? Thanks alot

It's a little more extra compared to my recommendations, but either is fine for good balance.

When turning on intellithermal do I have to turn off vdd and corecontrol? Also do I have to turn off mpdescion?
