Don't know whether it is right place or wrong but I wanna know one thing, that when I'm trying to compile a kernel for my LENOVO K6 NOTE, after adding features like new cpufreq_governor, compilation was successful but nothing appears in governor list in kernel auditor.. in configuration menu the governor appears but not in compiled kernel..
PLEASE ANYBODY HELP

hi.. i need some advice/guide regarding this matter..
first of all, i'm planning on compiling custom kernel myself for my ace. i've succesfully compiled a kernel on my debian box using kernel sourcecode from samsung and also applied bfs patch. but now i dont want to just stop here.
the problem is i dont know where to look for those undervolt patch, smartass governor patch, interactive governor patch etc etc. gooling for "android kenel patch/module" just bring me to precompiled kernel thread, not the source patch itself. so maybe anyone can guide me the right direction? thx before

better to see the github site, lot of kernel source with many patching in there. and i think, for the much customized of samsung kernel, you can just patching, manual diffing will more better because samsung kernel is not vanillaish android kernel. much modification in there.

Custom kernel for the Ace on it's way..?
Hello! I just recently got a brand new MyTouch4GSlide ($5 from t-mobile xD) Anyhow since the lack of development going on for this phone I decided to join in and do my part... My original plan was to create a simple CM7 Kernel with support for UV and OC + Smartass... I have successfully in the past week set up my ubuntu virtual machine, kernel source, kitchen (boot.img extract/compile), voltage table & have successfully compiled a custom working kernel for my device, but i just need a bit of help.... I have 3 specific questions wich hopefully someone will be able to answer so I may get better with developing and continue developing in the future...
1) Adding new frequencies to the kernel
-I have created my voltage table and have added it to the file acpuclock-8x60.c (Which is corresponding to my device) located in /arch/arm/mach-msm O have also disabled the performance lock in the .config file using the make menuconfig command but when I compile the kernel and flash it setcpu does not recognize the frequencies... Did I not edit the correct file? Am I missing a lock placed by HTC somewhere else?
2) Adding Smartass
-I have found 1 source for the smartass module but whenever I try to compile the module I get #define OFS_KALLSYMS_LOOKUP_NAME 0xc009684c // kallsyms_lookup_name any reason why this is? am I using the wrong source? is there an easier way?
3) WiFi Module
-Whenever I compile my kernel the WiFi does not turn on... Probably because I have not compiled a Wifi module -_- but how can I compile a WiFi module? do I use the same source as the kernel? how would I go about doing this? how do I pack it with the boot.img?
Thats all for now... I shall edit this if I have more questions... I shall constantly be checking this thread hoping for some responses... I am eager to get this working!
Thanks in advanced! ~GiGoO
P.S. If you want you may add me on Skype if you would like to help me with this xD (robster105)

Hey Rob, I wish you the best of luck and don't give up!
The one thing I can say is when I was compiling my own kernels a while back and when I was trying to do the exact same thing and add different frequencies, if I remember correctly, there is a couple files that need to be changed, not just one, but don't quote me on that
I would also try getting help from other phone developers too. Post in the Q&A section of the phones, you might get more help that way.
Other then that good luck!

Hey guys,
So I've been searching around for a while now and I could not find any updated guide on porting/building custom kernels. I need a lot of help for this, as I am completely new and do not know anything to do with kernel stuff. I do my part by finding out whats a ramdisk and stuff, but please pardon me if I ask very stupid questions which may give you cancer.
I asked quite a few people, but all those don't reply. I won't list names, but just to let you know I tried.
Anyways, my problem here is I want to port a kernel which isn't available for my device, i9305. First kernel I want to try porting is boeffla kernel. Here is the repo --> https://github.com/n0aaz/boeffla-kernel-cm-s3/tree/boeffla13.0_u600 I am continuing off @aaz03 's work, as his laptop spoilt or something. In the first place, when I tried to use the script bbuild.sh, the terminal window immediately closes after a bunch of stuff happened and I cannot find the .zip. I don't even know if there's an error in building because terminal window immediately closes after a huge bunch of text showed up
I would also want to port other kernels in the future but I guess I'll get some basic knowledge of kernels first.
Thanks,

Told you in private : launch the script using
Code:
sudo ./bbuild.sh
The terminal closing problem is due to a syntax error.
Also the kernel, first time I managed to build it was booting, not working, it booted until lockscreen and then immediately bootloop. Will upload the faulty kernel for those who want to try, for every dev/contributer that can help please come and let us make a glorious boeffla kernel
The boeffla I built is from zanezam's custom for i9300 and everything is on my github.
EDIT: make a thread in i9305 Q&A, no one gives a shirt about i9305 here and we will be more visible to i9305 users

Nope, I tried and the terminal still dies.
Anyways I posted here because not only boeffla I also want to port AK. But boeffla first since the "base" has been set I guess...
edit: I'll make a thread in i9305 Q&A tmr, no time today.

Here the booting boeffla I built : https://mega.nz/#!PEh2mTCL!jvkZ-xaDXiMlymTUMxeObZ471-d_9kCGP2xAYF67Pmw it will probably help
Hello,
I asked Boeffla once and he told me to pick all commits from his Boeffla Kernel to your kernel. At your site, I would start with adding some custom Governos. And after that pick some schedulers.
Clone your kernel (git clone)
Fetch the other kernel repo (git fetch)
Pick the commit (git cherrz-pick)
Push the commit (git push)
Then you will see n0aaz committed with Trafalgar-Square (your username) on date in GitHub.

Yeah I agree this is a normal procedure for a kernel port but for us it isn't really a port as the i9300 and the i9305 share the same smdk4412 source with very few differences so you can easily recycle the folder and I take as proof that it is booting. Plus I have zero knowledge about standalone kernel building so I'm happy with the boeffla building script...
I have never rooted it or touched my g850 's kernel, it is 5.0.2 lollipop and kernel version is 3.10.9-8213318.
I want to benchmark performance and power consumption on exynos5430 with HMP scheduler and Energy Aware Scheduler.
I have questions about this.
Is my g850's kernel include HMP scheduler(Global task scheduler)? I mean, does it applied on my kernel and my g850's processor is running with HMP Scheduler without any configuration?
And, If I want to compile 3.18 kernel which include Energy Aware Scheduler, what kind of defconfig do I have to use?
I checked arch/arm/config, but there are only arm's fundamental defconfig files.(like acs5k, armadillo, exynos, versatile .... etc)
Is there any defconfig for g850? or can I use 5430-base_defconfig(I can't paste link here)?
If I compiled 3.18 kernel, How can I install it on my device? I tried to unpack original rom and change kernel image, but it's md5 file, so I dunno how to. Is there any ONE SIMPLE WAY to just install my zimage on my device? or appropriate guide to install it on g850. I found bunch of guides on google, but most of the uses nexus.
I'm so desperate to do this, I wish I can get an answer here. Thanks
hi guys
i need some ways to add overclock gpu(mali880) cpu on my kirin955 kernel
i want to know how kernel developer find so many opmtimazition on their kernels?
is there any repo for module and hack and optimazation for android kernel development?
Any Help?
