                   This is Dorimanx Kernel 13.X

You can build this kernel easily on BBQLinux (http://www.bbqlinux.org/), an Arch based distro for Android Devs.

Install it and simply do these commands:

Use 64BIT installation or build will fail!!!

To compile you need:

sudo pacman -S bc

set your shell to bash

chsh -s /bin/bash YOUR-USER(best if it will be root)

set permissions on temp!

sudo chmod -R 777 /tmp

Clean TMP

sudo rm -rf /tmp/*

To clone this repo

mkdir ~/samsung-i9100 cd ~/samsung-i9100 git clone https://github.com/gsstudios/Dorimanx-SG2-I9100-Kernel.git git clone https://github.com/gsstudios/initramfs3.git

allow access for login as root to ssh

vi /etc/ssh/sshd_config

look for

PermitRootLogin yes

uncomment

PermitRootLogin yes

save file. (shift :wq)

To enable SSH access to machine:

open terminal

sudo systemctl start sshd

to start it, and to make it start always at boot

sudo systemctl enable sshd.service

ssh is online now :)

Install normal text editor!

sudo pacman -S vim export EDITOR=/usr/bin/vi sudo rm /usr/bin/vi sudo cp /usr/bin/vim /usr/bin/vi echo "syntax on" > $HOME/.vimrc echo "colo elflord" >> $HOME/.vimrc echo "export EDITOR=vi" >> ~/.bashrc

setup git to help you to work :)

cd ~/samsung-i9100/Dorimanx-SG2-I9100-Kernel

tell git who are you!

git config --global user.name John Doe git config --global user.email johndoe@example.com

set helpers

git config --global push.default simple git config --global alias.last 'log -1 HEAD' git config --global alias.unstage 'reset HEAD --' git config --global alias.hard 'reset --hard' git config --global alias.co checkout git config --global alias.br branch git config --global alias.ci commit git config --global alias.st status git config --global color.diff auto git config --global color.ui auto git config --global color.status auto git config --global color.branch auto

check all config

git config -l

set auto complite commands for git when using bash shell

cp /usr/share/git/completion/git-completion.bash ~/.git-completion.bash vi ~/.bashrc

add at the bottom if file

source ~/.git-completion.bash

save! shift :wq

to make it work exit and loggin to ssh/terminal again.

To start the build

****

!!!!Login to SSH/Terminal as ROOT user!!!!!!

****

now if you are ROOT, then build, if you are not ROOT, go away.

cd ~/samsung-i9100/Dorimanx-SG2-I9100-Kernel sh load_config.sh sh build_kernel.sh

Enjoy!

==================================================================

This kernel must be compiled on Ubuntu Server/Desktop 64BIT ONLY!!!.

Kernel not support 32BIT!

It is important to keep this one, otherwise the kernel will be compiled

but it won't boot as the script will fire errors.

It is important to install this otherwise the linaro GCC will fire errors

================================================================== My info guide.

How to cherry pick commits from other branch to yours.

fetch new branch, checkout inside.

git fetch git://github.com/dorimanx/Dorimanx-SG2-I9100-Kernel.git git checkout FETCH_HEAD

now git log

find the hash number of the oldest commit that you want and the newst commit that you want, it's a range of commits! :)

now example! ( the .. from old to new is a must) rm -f *.patch (clean all old junk)

you must use commit hash -1 from commit that you want to start adding! just take commit that you have/not want as first!, git format-patch will start from next to one you put as the oldest.!

then "OLD" + "NEW" are info, dont write.

git format-patch "OLD" 177e5c7ce53b6d06b9ee3448c00215ba6d70ffc9..c87ade04d28d2024b8ed2000346aa568a07a7f0b "NEW" git checkout DESTINATION/YOUR branch. git am .patch rm -f .patch git push

all done :)

if git am fail to add patch, you can stop and try to fix the commit, that is another story :)

UNIX & Linux Shell Scripting Tutorial

TOC | Introduction | Variables | If/Else | Looping | Cases | Functions | Search & Sort | Advanced | Forum

If/Else

In order for a script to be very useful, you will need to be able to test the conditions of variables. Most programming and scripting languages have some sort of if/else expression and so does the bourne shell. Unlike most other languages, spaces are very important when using an if statement. Let's do a simple script that will ask a user for a password before allowing him to continue. This is obviously not how you would implement such security in a real system, but it will make a good example of using if and else statements.

!/bin/sh

This is some secure program that uses security.

VALID_PASSWORD="secret" #this is our password.

echo "Please enter the password:" read PASSWORD

if [ "$PASSWORD" == "$VALID_PASSWORD" ]; then echo "You have access!" else echo "ACCESS DENIED!" fi

Remember that the spacing is very important in the if statement. Notice that the termination of the if statement is fi. You will need to use the fi statement to terminate an if whether or not use use an else as well. You can also replace the "==" with "!=" to test if the variables are NOT equal. There are other tokens that you can put in place of the "==" for other types of tests. The following table shows the different expressions allowed. Comparisons: -eq equal to -ne not equal to -lt less than -le less than or equal to -gt greater than -ge greater than or equal to

File Operations: -s file exists and is not empty -f file exists and is not a directory -d directory exists -x file is executable -w file is writable -r file is readable

Let's try using a couple of these in a script. This next script will ask for a user name, if there is not a file that exists with the name "username_DAT", the script will prompt the user for their age, it will then make sure that they are old enough to use this program and then it will write their age to a file with the name "username_DAT". If the file already exists, it will just display the age of the user.

!/bin/sh

Prompt for a user name...

echo "Please enter your name:" read USERNAME

Check for the file.

if [ -s ${USERNAME}_DAT ]; then

Read the age from the file.

    AGE=`cat ${USERNAME}_DAT`
    echo "You are $AGE years old!"

else

Ask the user for his/her age

    echo "How old are you?"
    read AGE

if [ "$AGE" -le 2 ]; then
    echo "You are too young!"
else
    if [ "$AGE" -ge 100 ]; then
        echo "You are too old!"
    else
        # Write the age to a new file.
        echo $AGE > ${USERNAME}_DAT
    fi
fi

fi

Run this program a couple of times. First run it and give it the user name of "john". When it asks for an age, enter the age "1". Notice that it will say that you are too you and then exit. Now run the program again with the name "john" and the age 200. This time the script will tell you that you are too old and exit. Now run the the script again with the name of "john", enter the age 30. The script exits normally this time, the program created a file called "john_DAT" which contains the text "30". Finally run the program one more time and give it the name "john". This time it will not prompt you to enter an age, instead it will read the age from a file and say "Your are 30 years old!".

We introduced something else new in this script. On line 10 of the file, we see the code:

AGE=`cat ${USERNAME}_DAT`

This is how you execute a command and put the text output from the command into a variable. The unix command cat reads the file named ${USERNAME}_DAT and outputs it to the console. Instead of putting it to the console in our script, we wrap the command with the character `, this puts the text into our variable AGE.

You can test multiple expressions at once by using the || (or) operator or the && (and) operator. This can save you from writing extra code to nest if statements. The above code has a nested if statement where it checks if the age is greater than or equal to 100. This could be changed as well by using elif (else if). The structure of elif is the same as the structure of if, we will use it in an example below. In this example, we will check for certain age ranges. If you are less than 20 or greater than 50, you are out of the age range. If you are between 20 and 30 you are in your 20's and so on.

!/bin/sh

Prompt for a user name...

echo "Please enter your age:" read AGE

if [ "$AGE" -lt 20 ] || [ "$AGE" -ge 50 ]; then echo "Sorry, you are out of the age range." elif [ "$AGE" -ge 20 ] && [ "$AGE" -lt 30 ]; then echo "You are in your 20s" elif [ "$AGE" -ge 30 ] && [ "$AGE" -lt 40 ]; then echo "You are in your 30s" elif [ "$AGE" -ge 40 ] && [ "$AGE" -lt 50 ]; then echo "You are in your 40s" fi

More will be added later.

Linux kernel release 3.x <http://kernel.org/>

These are the release notes for Linux version 3. Read them carefully, as they tell you what this is all about, explain how to install the kernel, and what to do if something goes wrong.

WHAT IS LINUX?

Linux is a clone of the operating system Unix, written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX and Single UNIX Specification compliance.

It has all the features you would expect in a modern fully-fledged Unix, including true multitasking, virtual memory, shared libraries, demand loading, shared copy-on-write executables, proper memory management, and multistack networking including IPv4 and IPv6.

It is distributed under the GNU General Public License - see the accompanying COPYING file for more details.

ON WHAT HARDWARE DOES IT RUN?

Although originally developed first for 32-bit x86-based PCs (386 or higher), today Linux also runs on (at least) the Compaq Alpha AXP, Sun SPARC and UltraSPARC, Motorola 68000, PowerPC, PowerPC64, ARM, Hitachi SuperH, Cell, IBM S/390, MIPS, HP PA-RISC, Intel IA-64, DEC VAX, AMD x86-64, AXIS CRIS, Xtensa, Tilera TILE, AVR32 and Renesas M32R architectures.

Linux is easily portable to most general-purpose 32- or 64-bit architectures as long as they have a paged memory management unit (PMMU) and a port of the GNU C compiler (gcc) (part of The GNU Compiler Collection, GCC). Linux has also been ported to a number of architectures without a PMMU, although functionality is then obviously somewhat limited. Linux has also been ported to itself. You can now run the kernel as a userspace application - this is called UserMode Linux (UML).

DOCUMENTATION:

INSTALLING the kernel source:

SOFTWARE REQUIREMENTS

Compiling and running the 3.x kernels requires up-to-date versions of various software packages. Consult Documentation/Changes for the minimum version numbers required and how to get updates for these packages. Beware that using excessively old versions of these packages can cause indirect errors that are very difficult to track down, so don't assume that you can just update packages when obvious problems arise during build or operation.

BUILD directory for the kernel:

When compiling the kernel all output files will per default be stored together with the kernel source code. Using the option "make O=output/dir" allow you to specify an alternate place for the output files (including .config). Example: kernel source code: /usr/src/linux-3.N build directory: /home/name/build/kernel

To configure and build the kernel use: cd /usr/src/linux-3.N make O=/home/name/build/kernel menuconfig make O=/home/name/build/kernel sudo make O=/home/name/build/kernel modules_install install

Please note: If the 'O=output/dir' option is used then it must be used for all invocations of make.

CONFIGURING the kernel:

Do not skip this step even if you are only upgrading one minor version. New configuration options are added in each release, and odd problems will turn up if the configuration files are not set up as expected. If you want to carry your existing configuration to a new version with minimal work, use "make oldconfig", which will only ask you for the answers to new questions.
