I've managed to compile the latest source for our lovely device using a tutorial for the Thunderbolt. Is there a general guide related to our devices? Need to know folder structure and such for the 3D.

HTC hasn't released the latest source for the kernel in 2.17.651.5 yet. What folder structure are you talking about? Compiling a kernel gives you zImage and the modules that work with the kernel you compile. You can use koush's anykernel updater zip which will place zImage into boot.img (kernel+RAMDisk) and copy the modules to \system\lib\modules.

Not folder structure, I wasnt clear my apologies. I have anykernel updater. I was just seeing if there was any specific folder that listed all the compiled modules or if I had to go and manually pull them from each folder. I've been practicing with the .3 source just to get a feel of basic kernel dev.

Is it possible for me to edit my kernel to allow higher clock frequencies? I am trying to achieve 1700-1800mhz
Can i extract the kernel from my ROM zip?
Do I simply edit 'scaling_available_frequencies','cpuinfo_max_freq' & 'UV_mV_table'?
If so how can I gain write access to this file? Any info appreciated!

How do I open zimage
Sent from my GT-I9100 using xda premium
You can't unzip the zImage and make changes. You'll need to compile the kernel from source yourself.
Ok thanks for the reply. I am currently downloading the cm7 source code from github. Can you help with regard to overclocking?
Sent from my GT-I9100 using xda premium
You could try looking at the original overclocking commit and modifying it.
Why would you ever want 1.8GHz though? It'll almost certainly be unstable.

OK so what I've sussed out so far is as Oxygen ROM is cm7 based I can extract the boot.img from stable cm7 ROM (which is the kernel) and replace it with the Oxygen boot.img thus creating oxygen 2.3.1/wolverine, clockable to 1.6ghz.
I have found a tut on unpacking ramdisk, is this the boot.img?
If so can anybody tell me how id go about further increasing clock speed once unpacked?
Any help appreciated, cheers Andy
Sent from my GT-I9100 using xda premium
Like I said, it's not possible to change the available frequency steps in a compiled kernel. You can't unpack it and make changes, you've got to build it from source.
Thanks for the reply, I believe I have the source and instructions on compiling unsure what to edit. Am I rite in saying the kernel is generic to all devices and need tailoring to suite? Please forgive the noobness I like to dive in deep end. Hopefully studying comp sci in sept if I get my grades so maybe then ill be able to contribute to the forum a little better

As for why, my device runs real smooth even at 500mhz but have a friend who likes to gloat over a cf bench result id like to smash, that and learning more and as much as I can on android OS.

Oh no no. You are going the Samsung way I guess. In all Sony phones, we dont have a recovery partition. That means that we can't flash kernels from CWM. The only way is fastboot. So no way to include kernel in your rom zip file. Sorry. At the most you can only recommend users to use a particular kernel.

OHHHH!!... but in the tutorial by nero young on how to build a custom rom .. he has a sk17i and he uses his own custom kernel when he builds the rom... http://forum.xda-developers.com/showthread.php?p=26283930
so if i cant use a custom kernel .. how do i extract the kernel.sin into the rom?
Basically you just can't flash kernel with the phone.
Usual practive in our phones is to include th boot.img in the rom file and ask it to be extracted and flashed via fastboot through pc.
Hope it helps
Don't know about the tuto

You don't have to worry about the kernel when building a rom on stock rom. Just work on the system and you should have a proper working rom.

Yes. Kitchen requires a kernel for the working folder. Btw why do you need kitchen? If you need any help for developing your rom, just pm me.

Dude you can directly add root and busybox.and whatever you want. Check your pm.
Sent from my LT26i using xda app-developers app
Hi,
You can use the attached META-INF folder. It has only the basic stuff like basic symlinks and permissions required for the rom to work properly. Just check the comments in the updater-script to know where to add your tweaks.
Good luck developing

How do I extract a kernel from one rom to another rom?
I did do a search and from what I have read you can download both zips and extract the boot.img from one rom and put it in the other rom. Is this correct, a step by step on PC or phone would be nice. Or just extract boot.img from one rom then install the other rom and flash the other boot.img in TWRP on top of that rom. Again a step by step guide would help me. If I could get the source is there a easy way to make a flashable zip? Or if there is another method.
EDIT: I'm S-Off and 3.16 without touchpanel and trying to take one CM10 kernel from a rom and place it in another CM10 rom then flash.

Have you tried this? : https://play.google.com/store/apps/details?id=com.joeykrim.flashimagegui
Are you s-on?
If so, after extracting boot.img got to your folder that has your fastboot and adb exes in cmd and put your phone in fastboot usb and place your boot.img then issue the command: fastboot flash boot boot.img
Good luck!

Yes I am S-Off. Also with the program you linked to it looks like it is for S-On and most of the instructions that I find are for S-On. If I am wrong could you point me in the right direction with a guide for Flash Image GUI.

If you are s-off you can use the same commands or flash custom kernels, depending on the rom version you are using you just need to place the zip in your sd card and flash through twrp... Can you give more details of your setup and what kernel rom are u using or which one are you trying /want to flash?
For 3.16 you can use either thicklizard's Arc Reactor Kernel or flas2's Bulletproof... And depending on the rom you are running overclock/underclock - change schedulers or change voltage values using scripts or apps like setcpu, android tuner, etc...

I am trying to take the Evervolv kernel from its rom and put on the ChameleonOS. Thanks for the replies.
Used your sig to give more info:
Device: HTC EVO 4G LTE
ROM: ChameleonOS by TroNit
Kernel: Stock ChameleonOS
Radio: 1.12.11.1210
PRL:25014
HBOOT: 2.09
S-OFF: DirtyRacun
What did you end up doing?
Sent from my EVO using xda premium
I just gave up for the time the being tried all the CM10/AOSP roms on here and Evervolv kernel/rom is only rom that bluetooth on my vehicle like the Sense roms I used. I tried to use Flash Image GUI and it extracted the kernel I think but it put ChameleonOS on boot animation and would not load. Then I took the boot.img out of the Evervolv rom and replace it in the ChameleonOS and flashed and it would not load so it is either not compatible or I am doing something wrong.
Sounds like they aren't compatible.

If theres not already a master ICS source for your phone(No device tree),then yes you have to use the custom ICS rom on your phone so it can copy the right proprietary files to the source you repoed,or it will not run,you will get bootloops or a soft brick.

Unfortunately you can't compile Android or the Cyanogenmod source code that contains the Clockworkmod Recovery source code on Windows using Cygwin. Repo for example on the the critical tools for compiling from source doesn't work on Cygwin. Overall for compiling Clockworkmod Recovery from source a Unix based operating system such as Linux or OSX is needed.

From what I can tell his script takes a base already made CWMR for MTK processor devices and then modifies it through a series of hex edits to be compatible with that devices specific recovery partition block layout.
