I was going to make a kernel based on cm7 kernel, so how to start.
And how to add frequencies.
Adding over clicked frequencies is the main purpose, please help me somebody.
I want to make it for HTC explorer but there are nearly no devs who can help me that's why I am asking here

I really appreciate your work. Few weeks back.. i was trying to convince every Forum Admins to get
Explorer and similar devices.. a forum or atleast a sub-forum.. and happy to see they accepted our request..
Being a Lagacy Device.. they gave Explorer and others a complete forum!!

if u have some prior coding experience then adding frequencies, adding governors should be a piece of cake...
if no,
then you better check the gb cm7 rom for optimus one..try to find out the commit where actual work was started by the cm team on the kernel..you will find out how they added frequencies, governors and everything...:good:

That's nice idea of comparing with optimus one kernel

I would suggest you to try compiling the cm kernel for your phone whitout changes. (cm wiki)
After you succeed compiling the kernel, test if it is working.
Now you have a base you could start working on.
Next step could be to change something. (frequencies for the p500 have to be changed here: arch/arm/mach-msm/acpuclock.c)

Hi Guys. I know some of you are probably wanting OC in your ROM and might not want to wait for someone to implement it in there ROM or maybe you don't want to flash a ROM but just want the OC.
Well i am going to tell you how to get Z-OC in your phone. There are some thing you will need to remember and that is that this can be dangerous if you don't know what you are doing.
PLEASE NOTE: I AM IN NO WAY RESPONSIBLE IF YOU TURN YOUR PHONE INTO A PAPER WEIHGT OR TURN IT INTO A BRICK FOR A REPLACEMENT FOR YOUR WALL.
Here is what to do:
You will need the files at the bottom of this post and extract them.
For permissions. O means tick, X means leave unticked.
1. Place the install-recovery.sh file in system/ect/ and set permissions to:
ooo
oxo
oxo
2. Place these 3 files: zdzihu_oc.ko/ar6000.ko/tun.ko in system/lib/modules and set the permissions to:
oox
oxx
oxx
3. Go back to the install-recovery.sh file and select it and then select execute.
4. Reboot and enjoy
PLEASE NOTE: ONLY LOOK AND CHANGE THE CPU SPEED USING CPU MASTER. DO NOT TRY CHANGIING THE CLOCK SPEED WITH OTHER CPU APPS LIKE SET CPU OR YOU WILL LOSE THE 1113MHZ SPEED AND YOU WILL NEED TO GO BACK TO INSTALL-RECOVERY.SH AND EXECUTE AGAIN.
Awesome. Thank u so much

That's what the ar6000.ko is. Don't delete the original as I have not done that and my WiFi is fine. Also I need to add this to the op but everytime you reboot the phone you need to set the CPU again.

What does invoke mean?
EDIT: just searched it and yes still add it just in case you need to. You can always try without it and let me know or just stay on the safe side and add it. If I have time in a bit I will try without it as I think that the ar6000.ko is actually something to do with CM find coz if I remember rightly the CM kernels or gingerbread kernels had the ar6000.ko WiFi module and the 2.2 or 2.1 kernels had a different one but don't quote me on that one

It means OverClock

Correct me if I wrong, but for OC feature you need zdzihu_oc.ko only, others does nothing with OC.
Indeed, i am using terminal and insmod zdzihu_oc.ko and everything is fine...

Sent from my X10 using XDA Premium App
If it is the case only the z oc module is need then I will delete others but if I remember rightly the CM roms needed the ar6000.ko file for the WiFi to work and the tun.ko is a module for the CPU speeds to run by. Eg like CPU governer ect..... Correct me if I'm wrong but there must be reason they are there also the install-recovery.sh file has a lot of coding unlike the fps uncap one as where the one I added in this thread has a hell of a lot more also to do with the CPU governer.

I have tried to make an update zip also but if you try flashing this with a ROM with tweaks you will lose all the tweaks like with wolfs ROM. It is best to do it this way so you don't have the risk of something going wrong and also I get the same error with my zip and I used the update zip program to make it which set perms and signed and zips but still no go.

coz its already implemented. Unless you are on about his first ROM that is no longer in development. Also did you delete the original WiFi module

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!

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.
Sent from my GT-I9100
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

I do really apoligize if i sound incredibly noob-ish and dumb. If in theory i download a stock flashable xoom rom and then remove most xoom independent files such as kernel (modules) and other /system folders then flash it over a lightweight rom without tw apps, would i get a stock honeycomb rom? Mainly relying on compatible /system/app and system/framework folders?

nope. If you don't know what you're doing (and few of us do), just find a ROM in the dev forum and follow the instructions. If it was as easy as that, everyone would be a dev...

On the phone you can use a root file explorer app(available in the market) and go to system then apps and change the permissions to what he says above.
I was looking on the web for some kind of kdz file extraction and re-zip tool that could help with inserting the root file AND possibly the V20B bootloader unlock function for all of our L9 variants. Being a P769 user I would definitely gravity to using our phone first! But I found this link in android and it shows you how to extract a kdz via LG UPTESTEX MOD. Sound familiar, well it should because that's what we use to offline flash our phones. So it's saying that we can extract, modify then merge the files back INTO A KDZ for flashing. If this is true then we can manipulate the ROM! but I'm no devy so I can't so do. Here is the link for anyone curious about it:
Oh my apologies if I didn't put this in the right forum. I always wan to place things in the general forum so that I get maximum eyeage. But I placed it here for dev's to see.
Thanks for sharing! I hope the devs here can use this to their advantage! :thumbup:

Maybe we can load up cyanogenmod with the stock kernel a-la 2nd init with this method. THANKS
Well nice thought, but I think it wont work. I think so for a simple reason. We already tried that over at the p970 forum. I dont really remember of the dev who tried it, but it was either navossoc or xonar, if I remember correctly. He said something like, it s possible to extract the bin files, but he receives some nonsense code and doesnt know, how to interpret and put them back together. If you need the source, pm me please and I ll look it up
