[Q] Stock Kernel - Add frequencies and/or governors - Moto G Q&A, Help & Troubleshooting

Hi community:
I wanted to know if there's some way to edit frequency values on the stock kernel and hopefully to add new governors. I tried some custom kernels but right now I want to stick to the stock kernel because I read that it has a proprietary driver that manages CPU (MPdecision I think it is).
I would be willing to compile, test and stuff on my device but if someone knows an easier trick (build prop or stuff) I'll gladly appreciate it.
Also if there's a stock-based customized kernel out there with such capabilities (I searched but all are AOSP based) I would try it.

i don't know if it works but try using engineering mode..

This app was mentioned on XDA news today - claims to let you tweak CPU: (no mention of it requiring a custom kernel)

overclocking on the fly without a custom kernel

I found a link explaining how to overclock motorola milestone phone on the fly without any reeboot or flashing a custom overclocked kernel. This information might be useful for overclocking galaxy 3 mobiles and I think this would be a better way of overcloking, since it doesnot require flashing a separate overcloked kernel.

Since our phone is using s5p6442 cpu,there are some slight changes that has to be done. I tried and compared the guide with our froyo kernel source released by samsung.
I found the frequency table for our cpu to be present in
arch/arm/plat-s5p64xx/s5p6442-dvfs.c
But i couldnt find which function manipulates the frequency tables present here,I'm not a developer so I'm posting what i know here, Hoping some developer takes this information and implementes it.
downloading the source codes now....wonder if i can figure out anything~im just a noob

[Q] How to add SetCPU support to custom kernel?

Hi guys, first of all, I hope this is the right place to ask, if not then please move this thread
I want to compile a custom kernel for my device Spice Mi310. I want to know how I can add SetCPU support to my kernel (2.6.32.9)? I've seen many people here on xda enabling SetCPU support for their kernels, unfortunately my device isn't that popular so no one has an OC kernel for this device. I've compiled dozens of kernels for Linux PC's but I'm new to android kernel compiling
If any of the kernel hackers here on xda can help, it would be much appreciated
bump....no one?

Please help with kernel edit/recompile

Hello, I have an LG Optimus pad running honeycomb 3.0.1. There is very limited development for the optimus/g-slate right now, but there are a couple of custom kernels available. Unfortunately, the kernel I am interested in trying out is OC'ed to 1.5ghz by default and my tablet becomes unstable at anything beyond 1.2 so I can't get it to boot. I assume that the source code could be modified somehow to lower the default clock speed, but I'm not a dev and I have very little linux experience so I have no idea how to go about changing it. I have read a couple of guides regarding recompiling a kernel from source and I think I could handle the recompile if someone could just point me to the files/values I would need to modify. Any help would be greatly appreciated!

Kernel questions

Hello everybody,
I'm looking for a good kernel for an ICS rom (I'm still on stock 4.0.4).
I have been looking at [Kernel][S4 ICS][10 DEC][SENSE] Beastmode BRICKED Ville [Linaro -O3][3.0.56].
I have a few questions about that kernel:
1) does it support init.d scripts?
2) does it improve multitasking in any way? Other kernels use zRam for this purpose, but I don't understand if this kernel does that too. Has "Google Snappy Compression" (mentioned in the features) something to do with this?
3) will I need to use a 3rd party app (like kerneltuner) in order to undervolt? And will the undervolt stick when shutting down the phone?
4) will I be able to go back to the stock kernel by restoring a backup with TWRP?
Those features are implemented in Fusion kernel, although it's no longer mantained...
Thank you in advance, it's my first time studying the kernel subject, sorry for bothering.

Question - Wich LineageOS based ROM is Overclockable ?

Hi everybody.
I have testing some LineageOS based ROMs lately in my P5110 and P3110 and found no overclock option so far ?
Considering the low hardware profile in our tabs and the actual real overlclock, better user experience and battery tunning / real gain we get with some CyanogenMods 6.0.1, I see no point using, until now, the new LineageOS based ROMs!?
So I ask: Is there any known LineageOS ROM or compatible kernel with overclock potential that allows to improve the user experience as the "old" CM 6.0.1 does ?
Thanks

no
No luck here as well mate, I've been forced to stick with CM13 since OC and themes are a must for me
Best user experience, for me, is with CM 6.0.1 from "[ROM][P31xx][P51xx][MM][6.0.1][Linaro][SaberMod] CyanogenMod 13" (https://forum.xda-developers.com/showthread.php?t=2686613) and "[ KERNEL - AOSP] Dhollmen Espresso" from (https://forum.xda-developers.com/showthread.php?t=2176563&page=138).
Can run everything I need with good speed and make tweaks to allow battery savings even possible!
Hello everybody.
I have read previous answers, thanks.
Considering the time since the original question, I would ask again:
1- if there is no option so far to add an overclocked kernel to our tabs ?
2- I am not a developer, but maybe I could get the info needed to build my own overclocked kernel and share it with the forum, where to start from ? I think these would really be faster for those already with the proper skills to do it! I mean: do you developers really use your tabs without overclock nowadays ?
Thanks again.

1-There is still no overclock available.
2-I am not a developer (yet) but I think the tab is fast enough as it is (running Slim7 if you want to know) and I don't think overclock is necessary. The place to start for building a kernel is google. I think I saw a guide in the past.
Also, keep in mind that devs make things because they want to and get no reward for that. So don't ask or press them to make anything. If you create your own kernel it will be greatly appreciated, but I think you wouldn't like people constantly asking you for something (and yes, overclock has been asked for a lot of times in the past).
