[GUIDE] Howto compile your own Pershoot kernel for CM7 Final for Vision

Compiling Pershoot's Vision Kernel for CyanogenMod 7
Why would I do this?
1. You must enjoy punishment
2. You want to know how a kernel gets compiled for Android.
3. You want to modify your kernel somehow, such as adding the Interactive Scheduler to the default Pershoot config or switching between CFS and BFS.
4. You want to modify the overclocking frequencies or voltages.
I don't teach how to do anything but #1 and 2, the rest I might get into later, but this guide is the gateway to all that.
You will need a working Ubuntu system. 10.04, 10.10, or 11.04 should all be fine. I did it with 11.04, so bleeding edge is working 100%.
On Ubuntu 10.04 and 10.10, get the following packages:
Code:
sudo apt-get install git-core gnupg sun-java6-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev
On Ubuntu 11.04 get:
Code:
sudo apt-get install git-core gnupg openjdk-6-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev
Let's create our compilation area:
Code:
cd ~
mkdir kernel-compilation
mkdir kernel-compilation/toolchain
mkdir kernel-compilation/finals
mkdir kernel-compilation/staging
Download the following files:
http://www.mediafire.com/file/5aqhkl69fq75253/arm-eabi-4.3.1.zip - Unzip to ~/kernel-compilation/toolchain
http://www.mediafire.com/file/7lo2ctg7r56urky/staging.zip - Unzip to ~/kernel-compilation/staging
And lastly, grab the source from Pershoot's GIT, which will end up in kernel-compilation/vision-2632:
Code:
cd ~/kernel-compilation/
git clone https://github.com/pershoot/vision-2632.git -b gingerbread
Next we'll set up the compiler to use the ARM toolchain through an environment variable to make it easier later:
Code:
export CCOMPILER=~/kernel-compilation/toolchain/arm-eabi-4.3.1/bin/arm-eabi-
Next we'll use Pershoot's default configuration file as a starting point:
Code:
cd ~/kernel-compilation/vision-2632
cp arch/arm/configs/pershoot_vision_defconfig .config
If you wish to modify his configuration:
Code:
make ARCH=arm CROSS_COMPILE=$CCOMPILER menuconfig
Next we'll compile the newly configured kernel:
Code:
make ARCH=arm CROSS_COMPILE=$CCOMPILER -j4 (replace 4 with the number of physical processor cores on your system, or leave the -j option off altogether if you don't know)
And the modules:
Code:
make ARCH=arm CROSS_COMPILE=$CCOMPILER modules
Now we'll start installing the kernel into our staging area.
Copy the kernel image from the source area into staging:
Code:
cp arch/arm/boot/zImage ~/kernel-compilation/staging/kernel/zImage
and install the modules (and fix where it puts them):
Code:
make ARCH=arm INSTALL_MOD_PATH=~/kernel-compilation/staging/system modules_install
cp ~/kernel-compilation/staging/system/lib/modules/2.6.32.38-cyanogenmod/kernel/drivers/net/wireless/bcm4329/bcm4329.ko ~/kernel-compilation/staging/system/lib/modules/bcm4329.ko
rm -rf ~/kernel-compilation/staging/system/lib/modules/2.6.32.38-cyanogenmod
Now let's finish up by zipping it all into the finals area:
Code:
cd ~/kernel-compilation/staging
zip -r ~/kernel-compilation/finals/mykernel.zip *
Now go to your finals directory and get to flashing!

dude, this is one amazingly simple tutorial I have almost zero ubuntu experience, and i have literally NEVER created my own anything for my phone, much less something as seemingly complex as the base kernel, but your easy walkthrough made it one of the easiest things Ive ever done, and now I have a working kernel with all the features i was looking for but never knew how to make myself
EDIT: may have spoken too soon. The kernel compiled fine and booted fine, but when i look for my added governors (interactive and conservative) in the listings, they dont appear there. any thoughts on what I need to do?

Am I right in assuming that the CPU frequencies/voltages are in /arch/arm/mach-msm/acpuclock-7x30.c , and that modifying those values in gedit (default program that opened when I doubleclicked it) would stick once I compile the kernel?

I'm assuming that you did the 'make ARCH=arm menuconfig' step and didn't properly save your changes. When you exit the menu it'll ask if you'd like to save, obviously select 'yes'. Don't choose the option to save an alternate config at the bottom of the main menu, just keep hitting exit until it asks to explicitly.

The short answer is yes, the long answer is that while that is indeed where the frequencies and voltages are stored, its pretty greek to me. I attempted to copy the 1.9 ghz acpuclock-7x30.c from another post on this forum and it doesn't seem like it compiled it, I still only made it to 1.5.
I'm going to investigate both this and where exactly the smartass governor source is and update this guide later.

lol, thanks i had found my mistake, and i just started it from after where it had me retrieve the files (which of course, i already had from before) and it got me to the right place to run the command. everything seems to have worked, but ill see once my phone boots.
EDIT: that did it! thanks again, bro

Instead of:
Code:
make ARCH=arm CROSS_COMPILE=$CCOMPILER -j4 (replace 4 with the number of physical processor cores on your system, or leave the -j option off altogether if you don't know)
You can use this:
Code:
make ARCH=arm CROSS_COMPILE=$CCOMPILER -j`grep 'processor' /proc/cpuinfo | wc -l`
that will put the right value based on your processor.
Out of curiosity, why is the interactive governor & others left out of pershoot's kernel in the first place?
I'm wondering if there are compatibility issues or other optimisations with undervolting etc and you may be running the risk of causing problems/damage to your hardware.

I only ask as, in pershoot's kernel the sysfs cpufreq directory differs from what seems the norm (from what I've seen); There are two cpufreq directories in (cpu & cpu0), but we only have one processor?
Dunno, maybe I'm just being paranoid and need to download the source and investigate...

Yeah I left that out for simplicity of the guide. Most people should know how many cores they have.

I actually have some issues using BFS (his default scheduler) with the interactive governor regarding stability. I'm assuming that BFS is the culprit for leaving it out.

Seems I was right about the CPU frequencies/voltages being there - I finally compiled a kernel that booted - I added a frequency value of 184Mhz, and SetCPU reflects this.
Thank you so much for this guide - I'm so chuffed with myself compiling a working kernel

(Q) Kernel building 101

I am a native Linux user and have configured/compiled *nix kernels dozen of times.
I was wondering about the HTC kernel and how it my differ from let's say a gentoo build?
I have found little to none on kernel programing, I must be blind. Can someone direct me to some tutorials? I'm not trying to re-program, I'm trying to re compile the Droid kernel and see what options and what it could take to ultimately port the Linux aircrack-ng suite over to Droid.
.
Sent from my ADR6300 using XDA App

Hey. I'm not sure about the kernel compiling part, but bump for that stuff. The aircrack part I've heard that the encryption for aircrack en mass is incredibly slow on arm procs. However if you find out some info, I'd be right there with you

Oh and yes, I'm part of the Gentoo clan also. So I'm no stranger to compiling and troubleshooting kernels. Haha or any number of other related problems
Sent from my ADR6300 using XDA Premium App

You just need to grab an arm cross compiler and build with that. You can use the one provided by Google or a number of others. Other than that its pretty much the same as building a kernel for your desktop. I'll post some more detailed instructions later if you need them when I have access to a computer.
Sent from my ADR6300 using XDA App

Im running gentoo, backtrack and kubuntu. I really enjoyed installing gentoo, really helped learning more of the innerworkings of Linux .
That would be great if you could suggest some material chad. I'm currently running your latest kernel and have no problems. Thanks for all of the releases, I bet its been a long road.
Sent from my ADR6300 using XDA App

Okay, kernel building 101:
You need to grab a few packages first. If you're running (k)ubuntu/debian you need:
Code:
32bit and 64bit systems:
git-core gnupg sun-java6-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev
64bit only (in addition to the above):
ia32-libs lib32z1-dev lib32ncurses5-dev gcc-multilib g++-multilib
Then you need to grab a cross compiler. You can use the one provided by google:
http://dl.google.com/android/ndk/android-ndk-r5b-linux-x86.tar.bz2
or grab one of numerous others (codesourcery, I believe there may be one in the ubuntu repos, etc etc.)
extract that somewhere.
Grab the kernel source of your liking (from developer.htc.com or from someones github).
Go into the kernel working directory and then:
Code:
export CROSS_COMPILE=wherever_you_extracted_the_ndk/android-ndk-r5b/toolchains/arm-eabi-4.4.0/prebuilt/linux-x86/bin/arm-eabi-
make ARCH=arm whatever_defconfig (you need to find the name of the defconfig you want to use, they're located in arch/arm/configs)
then do as you please to the config / source etc. If you want to use menuconfig make sure you do:
Code:
make ARCH=arm menuconfig
when you're ready to compile:
Code:
make ARCH=arm -whatever_flags_you_want_to_set
then you have to package up the kernel / modules how you want and flash them. I use koush's AnyKernel as do most others. You can just grab a random zipped kernel on here and replace the zImage and modules with those from the kernel you just built and flash.
when its done building the zImage is located at:
arch/arm/boot/zImage
The modules are located all over depending on which ones you built. I generally only include the wifi module and one for cifs. They'll be at
drivers/net/wireless/bcm4329/bcm4329.ko
and
fs/cifs/cifs.ko
Good luck have fun!

Thank you

Amazingly, you have me compiling a kernel in about 10 minutes of work, vs the couple hours I've spent trying to get it before. Granted last time I was compiling an arm toolchain from scratch, which was a little more bothersome lol

[Dev Tutorial] Kernel compiling for PrimoC/U

Hello everyone. Today I decided I wanted to give back to the One V community with a tutorial on building a kernel. This is not specific to the Primoc/u and contains the directions for both. The source even includes both! So lets hit the ground running.
Note: for the most up to date instructions visit here
Now youll need to have access to sudo to get the packages needed. here are the commands to get packages
Ubuntu 10.04-11.10:
Code:
sudo apt-get update; sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev libc6-dev lib32ncurses5-dev ia32-libs x11proto-core-dev libx11-dev lib32readline5-dev lib32z-dev libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc gcc
Ubuntu 12.04
Code:
sudo apt-get update; sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 libgl1-mesa-dev g++-multilib mingw32 openjdk-6-jdk tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386 gcc
Now, to get the source run these commands
Code:
cd ~/
mkdir kernel
cd kernel
git clone git://github.com/teamblueridge/MSM7X30_KERNEL.git onev_kernel
cd onev_kernel
first you are changing to your home directory. Next your making a folder for kernels, and then pulling the source from github. This source is modified and maintained by me, so I know it stays working. Finally your changing into the kernels directory. Now how do we build this thing you ask. Well we have to do some more prep work. Lets start that prep work
run these commands
Code:
cd ~/
mkdir toolchains
cd toolchains
#this takes some time
git clone https://android.googlesource.com/platform/prebuilt android_prebuilt
cd ~/kernel/onev_kernel
Now we select our branch
for ics run
Code:
git checkout ics
For jb
Code:
git checkout jb-hack
Now were ready to build. Basically your grabbing the android prebuilts which includes the needed toolchain in the steps before.
Now heres the fun codes
Okay below, i have a -jX in the command. This is the number of parallell builds. This will be the number of your CPU's plus one. If you have no clue how many cpus you have run this code below and add one
Code:
grep -c processor /proc/cpuinfo
To make CDMA
Code:
make ARCH=arm primoc_defconfig
make -jX ARCH=arm CROSS_COMPILE="~/toolchains/android_prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-"
To make GSM
Code:
make ARCH=arm primou_defconfig
make -jX ARCH=arm CROSS_COMPILE="~/toolchains/android_prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-"
So whats going on here you ask now? your using gnu make to build a kernel! arm is the architecture, CROSS_COMPILE is the toolchain we downloaded and -j`grep -c processor /proc/cpuinfo` will find the number of cpu cores you have and adjust the speed for your system!
So now your kernel is created and you want the kernel image to stick in your boot.img. Well its always located at ~/kernel/onev_kernel/arch/arm/boot/zImage any modules you selected are listed at the end of the build
If you were wondering, you can also modify the .config with this command
Primoc
Code:
make mrproper"
make ARCH=arm primoc_defconfig
make menuconfig
Primou
Code:
make mrproper
make ARCH=arm primou_defconfig
make menuconfig
Want the easy way out? Try this script
https://github.com/simonsimons34/kernel-building-script

reserverd for future use

Perfect!! Now I can remember how to do it when I don't want to waste Jenkins!

Nice one! :good:

At the beginning, why not just have them export "~/toolchains/android_prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-" as CROSS_COMPILE? I am sure there is a legit reason why, so I am not being a stink head. I suppose that unless the user added it to .bash_profile, they'd forget to do the "export" command each time...

You actually answered your own question there this is meant to be easy to follow and not go into too much depth where users unfamiliar to linux cant follow. Its trying to get people enjoying the ease of linux and not be too easily scared off. Also, forgetting to export was the exact reason I didn't have an export. This hurts nothing, afterall

got an error. followed the guide step by step, Ill fix it myself im just letting you know.

ok first awsome of u to share it with us ok ive ran the commands with ubuntu and ive done the whole process and when it is finished and the kernel is done what do we have to do how to we convert it to a image file and get it on the device im sure this is a stupid question and a waist of ur time i appoligize for me being a noob

Mods/admins recently had a discussion on where guides/tutorials should go and it was decided that the General section is the place for them. Moved there.

No no this is a tutorial. Its meant to allow people interested to be able to learn and do it. The next big thing may come from someone that gave up. Everyone needs help along the way. Once you get the kernel compiled, you can download android kitchen from here. I don't have a link, Google will suffice. So take that open menu with ./menu now go yo 0>12>w>x>0>x and go to the boot extracted folder. Note you must set up kitchen from a sick kernel zip that I have released. Now once in this directory delete the zImage there and replace with the one you compiled. Now go to ./menu 0>12>b>x>0>x and in the Working directory your new kernel is ready to be sent to your phone! All you have to do after that is when the ROM is booted run
adb remount
adb push /path/to/bcmdhd.ko /system/lib/modules/bcmdhd.ko
Enjoy

[Kernel Base][3.4.55][Dev]Bare Repositories of TW/AOSP Kernel (4.3 Sammy Sources!)

Up-to-Date Bare Repositories for TW/AOSP 4.2.2 Kernel​samsung-kernel-jfltexx​
Short Info:
I've made this repository to have a central place for everyone to fork their kernel base from. The advantage of this repo is that it is always up-to-date (as in the latest linux kernel version). Imagine the difference from starting at a 3.4.0 kernel base and 3.4.52 kernel base, there are thousands of new patches in that patch range. :good:
Repository Url:
Code:
https://github.com/broodplank/samsung-kernel-jfltexx
Repository Info:
Name: samsung-kernel-jfltexx
Description: Bare repositories for jfltexx (i9505)
Branches: tw-4.2.2 and aosp-4.2.2 (aosp 4.3 coming when 4.3 kernel sources are released)
tw-4.2.2 = Stock i9505 TouchWiz Kernel from Samsung sources patched until latest linux kernel version
aosp-4.2.2 = i9505g Google Edition Kernel (for AOSP 4.2.2 Google Edition and TouchWiz 4.2.2) (for i9505)
Getting the sources:
If you want to compile the kernel directly without much changes it's advised to clone it:
Code:
git clone [url]https://github.com/broodplank/samsung-kernel-jfltexx[/url] -b branchname
If you want to make your own kernel it's advised to fork the kernel:
- Login at github
- Go to https://github.com/broodplank/samsung-kernel-jfltexx
- Click Fork at the right top of the page

Usage Info:
Initializing first config:
Code:
make VARIANT_DEFCONFIG=jf_eur_defconfig jf_defconfig
Configuration:
Easiest variant (QT based GUI, needs libqt4-dev libqt4-core and libqt4-gui)
Code:
make xconfig
Default variant:
Code:
make menuconfig
Other less popular variants:
(GTK based, doesn't need any special packages)
Code:
make gconfig
(Ncurses based, needs libncurses5, libncurses5-dev and libncursesw5)\
Code:
make nconfig
Building Kernel:
Code:
export ARCH=arm
export CROSS_COMPILE=/path/to/toolchain/bin/arm-eabi-
make -jx (where x is the amount of cpu cores + 1)
Toolchains:
Toolchains that are suited for building the sources are:
arm-eabi-4.6
Click to expand...
Click to collapse
Building boot.img:
Code:
./build_bootimg
(Choose the rom type you will be using and it will be created in build/output)
Flashing boot.img and modules:
Code:
./flash_bootimg
(This is a process that pushes boot.img to your phone and then to the kernel partition, after that you can choose whether to push modules or not, and finally you can choose to wipe dalvik-cache or not and it will reboot.
Updating Info:
If you have forked the repository do this to fetch the updates from this repository:
First add it to the remote:
Code:
git remote add bare [url]https://github.com/broodplank/samsung-kernel-jfltexx[/url]
git fetch bare
Then search for the commit(s) that you want to merge
For 1 commit:
Code:
git cherry-pick [commit hash here, this is the last part of a commits url]
(for example: https://github.com/broodplank/samsung-kernel-jfltexx/commit/612bbea08b67f16dd5628cb8cd8406973f8fe821 would be: 612bbea08b67f16dd5628cb8cd8406973f8fe821)
For a range of commits:
Code:
git cherry-pick [commit a hash]^..[commit b hash]
Where commit a is the oldest commit and commit b the newest.
for example:
Code:
git cherry-pick 0bff3bdba64c58ea6100d72763f2be3acc9659db^..612bbea08b67f16dd5628cb8cd8406973f8fe821

Thanks, I just forked it.
I'm a noob at this but am learning fast. I've modified and compiled the 3.0.31 kernel for the 9210T but I'd like to now try 3.4. Appears none of the celox changes for board_msm8x60.c source came across from 3.0 to 3.4 so I think I've got my work cut out for me.

This guide is not working for me.
If I follow your guide the resulting kernel boots, but I have no sound and no 3G (PIN pad doesn't show up).
I'm on MF8 stock ROM. Yours, Ausdims or my own (based on Samsung Update 2 sources) work fine.
This is what I did:
$ git clone https://github.com/broodplank/samsung-kernel-jfltexx -b tw-4.2.2
$ make VARIANT_DEFCONFIG=jf_eur_defconfig jf_defconfig
$ export ARCH=arm
$ export CROSS_COMPILE=/path/to/toolchain/bin/arm-eabi-
$ make xconfig (no changes!)
$ make -j3
$ ./build_bootimg && ./flash_bootimg (selected 1 for TW)
What am I doing wrong?

Don't know.
I used the script to build the boot.img. If I do the same with my sources, it works.
In both cases, I haven't touched those files.

Tonight Ill do a little research on this and tell you the solution.

I remember when I started to make my first kernel, I had similar problems with the Samsung sources.
Wanam gave me his jf_defconfig file and it worked. He said that the config file by Samsung is crap. But I forgot to ask for details.
If I use my config file on your sources, it results in a bootloop, whereas they work fine with Samsung update 2 sources.
Does that make sense?

Still figuring out, why i cant even successfully compile the sources. With ktoonse sources it works.
But i'm still a beginner. Will see about that xP

I hate it -.- xD
Now it worked. And I do not know why... As I am pretty new to this, as already said, - could this be the problem? :
I think I made this:
$ make VARIANT_DEFCONFIG=jf_eur_defconfig jf_defconfig
$ make xconfig
$ export ARCH=arm
$ export CROSS_COMPILE=/path/to/toolchain/bin/arm-eabi-
Click to expand...
Click to collapse
instead of:
$ make VARIANT_DEFCONFIG=jf_eur_defconfig jf_defconfig
$ export ARCH=arm
$ export CROSS_COMPILE=/path/to/toolchain/bin/arm-eabi-
$ make xconfig
Click to expand...
Click to collapse
So I used xconfig before setting ARCH and CROSS_COMPILE.
Could that be the problem?
Atm i can not paste the error. The first one had something to do with a buffersize. Could "fix" that by setting "CONFIG_FRAME_WARN=1024" higher. Because it said it was 1032.
Second error was something like "‘ret’ may be used uninitialized in this function [-Wuninitialized]".
---------- Post added at 08:08 PM ---------- Previous post was at 07:32 PM ----------
Will add a new post for this, if it's okay.
And i hope it's okay to ask in here
So, first, as wrote in my previous post the compiling worked.
Now, i did the following:
1. Changed in the config: "kernel compression mode -> LZO
2. Removed "Optimize for size"
3. And changed the flag in the makefile to O3.
kernel/workqueue.c: In function 'freeze_workqueues_begin':
kernel/workqueue.c:483:11: warning: array subscript is above array bounds [-Warray-bounds]
error, forbidden warning: workqueue.c:483
make[1]: *** [kernel/workqueue.o] Error 1
make[1]: *** Waiting for unfinished jobs....
While writing this I reset "Optimize for size" and restart compiling. Now it does seem to work.
So i guess there is a problem with the flag. Where is the right place of the flag?

If you want to use O2 or O3, it requires some modification of config and make files.
The build boot.img script worked for me right away.

I do have a working build environment and I can compile and install a kernel that is better than stock kernel.
Only these sources don't work. How is that possible?

It will work if you have the right toolchain, I use this one:
http://www.mediafire.com/download/i...linaro_4.7.4-2013.07-build_2013_07_12.tar.bz2
It's an optimized Linaro toolchain (http://forum.xda-developers.com/showthread.php?t=2098133)

We've had one major update. 4.1.2. We started with zv7, zv8 and 9 were bug fixes. ZVB is the only major one I can think of. Zvc seems fairly minor.

Sorry to resurrect a dead thread but this is the only one that I saw that talks about compiling from LG kernel source.
I think I did everything like your instructions say but the output folder for my kernel doesn't have a zImage file. The closest name is Image but it's 14.4MB (way bigger than viper kernel, for instance) and it doesn't boot via fastboot boot Image. I'd appreciate it if anyone could give me some pointers.
EDIT: looks like I hadn't installed lzop, never mind.

I tried it using toolchain 4.6.3, among many others, and at best, the error was with the tsp.drv. When I removed it it compiled fine. But no boot.
How did you get past that error? Also, I have issues getting the modules to compile. How'd you fix that?
I'm trying to learn in my spare time so that's probably my problem. TIA

I just started with the source of Viper Kernel, it's ZVC based and already have some good fixes.
You can also see the source I'm working on at bmos/JB_LS970ZVC_Adder, although mine isn't booting right now (although I'm about to try toolchain 4.7 which it says it is optimised for)
