[Q] adding governors

how do i add additional cpu governors on a custom boot.img?

I think u need an app like no frills CPU or set CPU to control your CPU and apply govners
just re read your post and I wouldn't no where to start by adding them to a boot.img. do u mean built into the rom ?

i mean adding more governors to the boot.img... i think it has something to do with the kernel??? cm7 only has 4 governors by default... not sure if its the rom that needs editing or the boot.img?

Yes - governors are hardcoded in the kernel as far as I know - so you have to recomile a kernel from source - including your changes - and then flash it. It's not just a simple editing of txt files...
More info about other governors you will find at cyanogen forum - as they developed them (e.g. smartass v1/2).

You are correct sir.
Here's how to add a governor into a kernel (thanks to doomlord for his awesome github)

It shows all the files that need to be changed to add in a new governer ... if there's a + before a line, that means it was added, - means it was removed.

First step
1) Make sure you are running linux, or else it won't work
2) Download the source code from either opensource.sonymobile.com (for a stock kernel) or FXP github (https://github.com/freexperia/semc-kernel-msm7x30) for FXP Kernel.
3) unpack the source code
4) make changes to the source code you want to (i.e. adding in governors or io schedulers)
5) Follow this guide on how to build the source (note: the defconfig is probably different you'll have to check the /arch/arm/config folder to figure out which ones is the FXP one...)
6) Make it into a boot img following this tutorial
7) Try booting, if it works, check to make sure that the changes you made sticked. If it doesn't boot, well, you can ask questions in this thread and i'll help you
Any questions?

will try this.. tnx
EDIT:
-is it not possible to use with windows???
-so i have to build a kernel from scratch?? i can't simply add the new governors to an existing kernel?

A) Nope linux is the only way. I suggest ubuntu 10.04 LTE
B) unless you can create a way to decompile and recompile the zImage file (using linux) you're not going to get anywhere fast. (Governors are part of the built kernel, and can't be added into after the fact)

cant i simply copy the kernel from another boot.img file?? are there any other kernels that are compatible with cm7 fxp111 that has more governors??
is it possible to use kernels from other xperia phones using cm7??

1) technically yes, but kinda pointless because: 2) other than dooms (old) cm kernel (GSM) nope (I'm not sure if he had more governors or if it's compatible with with newer fxp)
3) nope, they use a different board.

[DEV/ROM][I957]Compiled ICS For i957[3/24/12]

Please keep in mind this is a work in progress and is currently intended for devs only. Do not flash if you don't know what you're doing.
Ok, after making some progress towards getting this thing ready for user-space, I've decided to finally start a thread on it just to see if I can get anyone interested or willing to help... This ROM is currently in below Alpha status (if there is such a thing) and does not boot, but I believe I can get it booting in about a week barring a system crash or a zombie apocalypse. Again, this is only meant for a jumping off point towards getting AOSP ICS on our I957s, so don't blame me if you flash this and your tab becomes bricked...

Base drivers can be used from the msm8660 ics source code provided by Code Aurora, and proprietary can be used from the stock Honeycomb firmware. Hopefully.

1. THANKS JO!
2. In order to boot, what is needed?

Thank You. Hell yeah! You guys rock. I'll help out if I can.

I'm willing to test too.

hey Jo there are some ICS CWM roms starting to come out for the skyrocket (ICSMOD5 is what I was looking at). Do you think with some script edits this could be flashed to the i957?

thanks to OP for attempting this. there are enough of us i957 users out there I think !

Yes, but the problem is we would probably need our own ICS kernel to get most of the stuff working. I'll try my hand at ICSMOD5, but I'm not sure if anything will work without a dedicated kernel.

Ok, I'm not really going to be able to use my tab for dev purposes this weekends, but if you want to try a port here's what you need to do.
1) Setup a build enviornment in dsixda's kitchen with ICSMOD5.
2) You'll need to look at the updater-script and change the partition blocks according to the Tab (e.g system needs to be 25 instead of 24).
3) Two ways to do 3. One: grab the kernel from this thread and put it in ICSMOD, or Two: You could just leave the kernel as is. I'm wary of option Two.
4) Flash it. If it doesn't boot, try to get a logcat and send it my way. If it does, then yay ICS.

OK I have followed these instructions; downloaded ICSMOD5, set up the kitchen, grabbed the kernel (assuming that's boot.img) from your zipfile in the first post of this thread and copied it to the working folder, overwriting the Skyrocket kernel.
Then I looked at the updater script to see if partitions need changing. Per this post the layout looks OK. Example: /system is p24 and /boot is p08 already.
So far so good? Planning a test for later today.

Exciting let me know how it goes

next time, you can do it in easier way though.
things you need : 1. kernel flashable zip( you can use the one from this thread) 2. boot.img you wanted to flash 3. win rar or 7zip or etc you prefer
the steps
1. extract boot.img you wanted from the rom flashable zip
2. open your kernel flashable zip
3. drag the kernel you just extracted to the kernel flashable zip content
4. voila the boot.img in the kernel flashable zip will be changed to the one you dragged
sorry, OP i'm just helping him, rather than using traditional time wasting method this one is lots faster

[XS][Kernel][STOCK+] V5.4.1OC [14-03-13] Recovery Independent!!

For those who have an UNLOCKED boot loader.
Kernel Stock+ is
= Sony latest ICS .55 kernel base
+ Auto-root with SuperSU
+ Init.d
+ Governor : Badass, Intellidemand, Interactive, Lagfree, Hotplug, Wheatley
+ I/O schedule : SIO, ROW, ZEN
+ elf extract (support recovery in FOTA partiton)
+ few tweak
+ OC to 1674Mhz(some version)
Stock+ V5.4.1 (OC)
- Over clock again to 1674MHz
- Port few lib, optimize from Open SEMC kernel
- Omit smartassv2 it cause my phone stuck at max frequently.
http://www.mediafire.com/download.php?hsma936uzlasgao
Stock+ V5.3 (Not OC)
http://www.mediafire.com/download.php?ohybzjcfu1ad6hc
- Update recovery TWRP 2.4.1
- Support elf extract so you are no longer tie to TWRP 2.4.1. Now you can update TWRP to the latest version or even install CWM. Check http://forum.xda-developers.com/showthread.php?t=2173202
- Fix Auto Root
- Remove PeqasusQ
- Add Lagfree, Hotplug, Wheatley
Stock+ V5.2 (Enable to Over Clock to match XSL speed)
http://www.mediafire.com/?4n0n5b04g76h8ew
- Change max frequency to 1674MHz
- Change RAM Disk to limit max frequency at 1512MHz
Stock+ V5.1 (update TWRP to V2.3.3.0)
http://www.mediafire.com/?ehkzz5lb59zgbxd
- New ramdisk structure. Now ramdisk split into two 1st for recovery and 2nd for Stock ICS boot.
- 1st ramdisk is ported from http://forum.xda-developers.com/showthread.php?t=2075562.
- 2nd ramdisk is exacted from sony stock kernel.sin merge with ramdisk from Advance Stock Kernel this should retain "autoroot" function and "init.d" support
Stock+ V2
link : http://www.mediafire.com/?vzpj4b6kpoa5zsl
This kernel feature
- build from .55 source + fix cache formatting issue
- little mod ram disk to set minimum frequency at 192000
- on demand tweak for better battery life.
- autoroot with superSU
- Xperia boot screen
Stock+ V1
Link : http://www.mediafire.com/?5sb5352k7pz5lc5
It is unmodified STOCK kernel extract from .55 kernel.sin plus CWM with auto root functionality.
I made a little mod to ramdisk to make it auto root with SuperSU instead of Superuser. The wifi module also replace with the one from stock firmware as well. The wifi module in Advance stock Kernel is not compatible with this kernel.
The kernel work just fine but I notice some bug when I try to format cache or wipe cache it will cause your cache partition corrupt. So if you like to use unmodified stock kernel please remember NOT wipe or format cache.
Well if you already wipe/format and want to get around the problem just simply install other kernel e.g. advance stock ICS17 or my stock mod kernel list above then format cache after that reinstall unmodified stock or you can leave it as it is.
Note.
- 28/01/13 : just found a bug regarding to setcpu and antutu set at boot not appear to set both core correctly. Please give No-frills CPU control or Kernel tuner a try but remember not to use with pagasusq.
- To install by fastboot just extract kernel.elf from the zip.
- Source is outdate because I can not upload a big file. I will update source as soon as I get proper internet connection.
- Now you can update TWRP to the latest version using goo.manager or even install CWM. Check http://forum.xda-developers.com/showthread.php?t=2173202
Feedback is appreciate.

I think this is different mate. The one you provide is not the real recovery. This is the same way people use for Locked boot loader. The recovery is locate in "system". If you format system you will loose it or if you install new ROM which has script to format system you probably loose recovery!!
Mine the recovery is not in system partition. It is loaded in ramdisk. You won't loose it even you format system.

I did it but for now it is in elf format. Please check first post.
You probably not need it because if you already rooted with ICS16 which come with superuser then the kernel will not reroot your system.
I'm still learning, could you please explain or give me some info about how you find user friendly of superuser? I read around here and lot of people said supeSU is quicker.

I am not a Dev but since my 1st Xperia NEO I have always used Superuser. I only once used SuperSu and its was last night When I was looking for a way to Root .55 of my Xperia S.
The used Interface it kinda messy and had a lot of option but in Superuser it just a few thing and easy to understand.
I don't know about others but As far as I know and Experienced most of the xperia user and even my friend use Superuser instead of supersu.

It suppose to work on windows but you will need cgywin. You also need some other software like phyton 7zip java etc. If you have Linux then it will be easy to install all those software.

Similar problem before.

The kernel was tested. So...no, I don't think that's from the kernel. Make sure you downloaded it entirely. And...I don't know, make sure you don't have any funny stuff like custom recovery or something like that installed on your phone. Other than that...it should work.

yeah, my bad. i don't know, this is my recovery or something else that weird. i try flash stock kernel by arsradu I got installation abort. i flash it when i using cwm 6.0.4.4 it's ok, no problem. I think this is not the file that corrupt. I'm using cwm 6.0.4.5 that hadi posted in his cm11 section, and install it by ATE.

My similar problem had been.
Dev asked him to Arsradu.Had given the answer to the above.
I don't know what the problem is.
6.0.4.4 try to install with.

Android developers changed the format of the shared memory area used to store system properties in the kitkat branch, then made some further changes (1, 2, 3, 4). Then they added backward compatibility with the older format, but only in one direction — now an executable linked with the new bionic libc can work even if the init process is from an older version (the commit log mentions the case when an older recovery is used to install an update.zip for a new version), but an executable linked with the old bionic libc will not work with a new init process. The latter case is what happens when you try to install a baseband zip file using the recovery built for kitkat — every update.zip file contains its own update-binary inside, and in this case update-binary is statically linked with the old (pre-kitkat) bionic libc. Because of this incompatibility getprop() calls in the updater-script do not return the expected values, and the compatibility check fails.
I could try to update at least my baseband zip files with a new update-binary, but this will take some time to check whether this could really work with different recovery versions, and then to upload all those files and update links to them.
BTW, the CWM recovery 6.0.4.5 image from this thread seems to be built in the 4.3.1 (JB) environment, therefore baseband update zips should be installable with this recovery version (however, I'm not sure about compatibility with kitkat ROMs).

maybe this is the answer to our problem.
Someone could try arco cwm 6.0.4.5, it is built in 4.3.1 enviroment the others should be 4.4.1 enviroment

i have a bug to report with this kernel: it's almost 1hour and a half that i'm surfing the web, using facebook app and playing, and my phone battery's percentage stuck at 23%!! (the percentage that was when i rebooted the device after flashing this rom)

Thanks for the report. I think I used the wrong zImage while compiling. I will fix it when I get home.

Here is anykernel version attached. You can flash it.

And remember that you can successfully flash "anykernel" version if you're running the stock kernel by Radu. Other than that you can face some system apps FC.
One can easily flash "anykernel" version over the stock kernel only once. The reason is the ramdisk.

Yes you are right. I will make a boot.img version when I get home from work.

What's this "anykernel"? A simple stock kernel, or a modified one by you without that bug?

Anykernel only flashes the kernel zImage and modules not the ramdisk. So this is a modified one and there is no battery stuck problem.

so this is your kernel but without the ramdisk. And what this will mean? If this is a modified one without battery stuck problem, why don't you post directly this in your first post? Just for knowledge

ramdisk is a small partition image that is mounted by the kernel at boot time. It only contains init and a few config files. It is used to start init which will mount the rest of the system images properly and run the init procedure.
Just googled it as I dont know the exact definition...
