Help with Doomkernel - Xperia SP Q&A, Help & Troubleshooting

Hi ! :cyclops:
I'm now using Doomkernel for one day but I don't really understand all the settings ....
I'd like to know what are the differences between the different schedulers and governors, the function of Zram and KSM :good:
Hope you can help me,
thanks

Try to use apps like SetCPU and Trickster MOD, in these apps you can turn nearly all kernel functions (Sorry for my bad english).

[Q] Kernerl and Governor (not a "what is....")

Hi
I have some things regarding Kernerls and Governors, and relax it's not about "what it is".
I am currently using Huexxx ROM 3.2 on a P970 v20N.
Now, Huexxx ROM is based on the stock rom.
So my question is:
1. a) Which Governors are included in the stock ROM?
b) If there are any other, how can I Change to another one?
2. All Governors I've found are for NOVA ROM or CM7 based ROMs, are there any for stock ROM? If so, where?
Thanks
Ps. was looking on Smartass/Smartass2.
If there is one for Stock ROM, please Link
Omg. Answer is in the First post in huexx thread.:banghead:

I must be blind.
real life and a forum is not that different. A student, or a any person who relies on web if need or want to know something begins in search engines, XDA is no different.
Kernel Governors, Modules, I/O Schedulers, CPU Tweaks
Governors are Android wide. not just for Nova nor CM. All android phones use them.
You mentioned nova, nova once used scripts in terminal to choose Governors:
su
nova
so zeus:
su
zeus
SetCPU and No-frills has problems with the stock ROM nor modified stock. Never use them.

remove a kernel? or change gouverner?

How remove a kernel i had tesmaks oc kernel and istaled spica one and had big battery drain
and, i have a wierd thing i only have performance or powersave and standart is perfermace i dont want to and i had installed set cpu to get powersave a boot
but i re instales tesmaks kernels but i want just to know how remove al kernels or change the gouverner? To ondemande or powersave at boot normale
Na just remove all kernels would also help
So thx if anny body knows a awnser to this questions thx
Btw im on tesmaks cm7kang 121
And would like to remove the performace gouverner eat my battery in 6h grr
And would lile all the gouverner options not only 2,or just no kernels just stock
Kernels get me sick to much bug blablabla
You can replace a kernel by installing a new one over it.
For governor, replace it with another one as well, eg powersave.

Can you make a version with also fast charge? Anyway working great

I'd like to see more feedback about this kernel as it looks promising. Thank you
Sent from my Nexus S using xda app-developers app
Kernel is good.. snappy.. nice performance..
There is no 1000mhz on the clock, so it's always on 1.24ghz ..
Pls add interactive governor.. I can't change the governor, only shows smartassv2 ...
Battery life not gr8.. But runs well.. power hungry games are smooth.. good overall..

This is inspired by SAMSUNG Infuse 4G, which use the same CPU and do not have 1.0GHz step in its stock kernel.
when there are both 1.24 and 1.0GHz, the governor will prefer to use 1.24GHz. And i thought it may help governor switch between steps faster.
so it won't eat more battery in this case.

I only built smartassV2(tweaked) into kernel. because it balance between battery life and performance.
There are also include kernel module of ondemand and conservative, you could load them by insmod if you like.
Thank you very much and must try it .

thanks for your kernel! i will try it now and report back
EDIT: unfortunately kernel doesn't work for me - i use it with paranoidandroid and rom was really sluggish at first (maybe cache-related...). then i startet setcpu for adjustments and the phone stopped responding with "colorful snow" on the screen. i pulled battery to reboot. - maybe my 9023 doesn't like 1,24 ghz (it is a bit picky, but 1,2 ghz at stock vol was never a problem).

yea, well, with stock kernel (and thalamus and matr1x and air kernel) everything runs fine, but i wanted to know, if there is a way to find out what exactly causes the problem with your kernel and my phone (which also might help somebody else). - raising the vol does not help that much, still some freezes from time to time (even though i'm above stock vols).

GT-S5830i Interactive Kernel, root, interactive,and much more

Hi friends of XDA, friends of Android, friends of S5830i, friends of ROM's, friends of Kernels, friends of....
This is my last creation: Interactive nit Kernel for GT-S5830i
Based on my kernel ([email protected]), i have created the Interactive nitKernel.
Kernel now includes a system app called nitManager to manage the kernel features and others:
- Set Max Frequency
- Set Min Frequency
- Set Prefered Governor
- Set Prefered I/O Scheduler
- Set Apps Install Location (Apps to Ext-SD for example)
- Set swap (the app will create the correspondig swap partition if not found and enable and disable swap feature)
- Download and Install Busybox if not detected in the device
- Download and install Superuser app if not detected in the device. (Installing Superuser app will slower kernelManager app)
Instalation:
Download the kernel from here:
https://dl.dropbox.com/u/68301491/PDAnitInteractiveKernel.tar
This version is only flashable through Odin.
Just put the file in the PDA section and flash.
Once installed go to your apps and find nitManager App, open it and start managing all the kernel options.
I have tested flashing the kernel directly from fully stock ROM, and works great.
From stock ROM you'll get everything you need to boost your device, su, kernelManager, busybox, swap, superuser, apps2sd etc...
Kernel Features:
Freqs:
156 MHz
312 MHz
624 MHz
832 MHz
Governors:
Intellidemand
InteractiveX
SmartassV2
Conservative
bcm21553
Performance
I/O Schedulers
noop

sio --> Got this one from Rafael Baugis Source. Thankyou Rafael, hope this is not an inconvenient.
Fatures:
Enabled Module Loading
Init.d Support
Improved kernel scripts (Many of them, i dont really know why Samsung is opensourcing such sources. I know this is a low cost phone, but...)
Swap support
Ramzswap support
Root --> Kernel is all ready rooted, su is in xbin as usual lol.
Camera, Flash, Wifi etc etc etc... is working fine.
Filesystem Support
ext2, 3, 4
Msdos
VFAT
YAFFS2
JFFS2
Hope you like it.
If you like it please dont forget to press the thanks button, this is always very nice.
ROM developers, please feel free to use my kernel in your developments. I have developed the kernel specially for all of you.
Thank you.
Nice
Can't I just Download Rafael.baugis Kernel and replace Thema Boot.img with yours? IT could be flashed with cwm.

Hi Android-fany, its not recommended. I have developed the kernel manager for my kernel. Im not sure it will work on Rafaels. Never tried anyway.
On the other hand the kernel manager has been developed to manage my kernel features, so traying what you say will limit Rafaels kernel to the features in my kernel

Only one updated kernel we have is CoCore, so it is best one. ROM, maybe HarshJelly/SamiOS for stock, or some CM (I think CM10.1 is most stable of all we have for now).
I used thunderzap 4.1 with jellymod 4.1 and was pretty dissapointed cuz games were not smooth...I will try Roms u mentioned...
