[GUIDE][HOW TO]Compile S5670 kernel with many Features :D

zcop · Jan 27, 2012

Menu:

1. Guide install Ubuntu

2. Download Source and Setup workspace

3. Feature
●Make kernel support EXT2, 3, 4
●Make Overclock, Undervolt kernel, add IO shedule and CPU Gorvernor
●Make kernel support Cifs Manager and DroidVPN( add cifs and tun module to kernel)
●Make kernel support SWAP
4. Finish your work - Compile kernel and pack new boot image

You need linux enviroment to compile kernel.
Suggest: Install Ubuntu 64bit.
Download:http://www.ubuntu.com/download/ubuntu/download
Select Ubuntu 11.10 and 64bit version

Hardware required:
CPU >= 1,5Ghz
Ram >= 2GB
HDD atleast 20GB space left

After complete download Ubuntu. You have 3 choices:
-Install Ubuntu in VMware
-Install Ubuntu like system OS
-Install Ubuntu like a soft in Windows
I recommend the 3rd way.

Extract ISO file with winzip or winra or 7z to a folder.
Go in to that folder run wubi.exe

Restart to complete install ubuntu.

If you want to uninstall Ubuntu: go to Control Panel and uninstall Ubuntu like other soft in windows.

Ubuntu 11.10 come with a wifi problem. Broadcom chip has no driver. Solution:
-Turn on wifi on S5670
-USB tether
-Now you have internet
-Follow pitures to solve problem

Download S5670 Newest Source release

https://opensource.samsung.com/index.jsp

Link Mediafire

Download Toolchain to compile kernel
https://sourcery.mentor.com/sgpp/lite/arm/portal/package8734/public/arm-none-eabi/arm-2011.03-42-arm-none-eabi-i686-pc-linux-gnu.tar.bz2
After download complete follow pitures

After all workplace should like this

How to open Terminal

Or use combo key: CTRL+ALT+T

Open Terminal copy command below an paste in Terminal

Code:

sudo apt-get install git-core gnupg flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev valgrind

Now you need a boot.img that you want to modify kernel. Exp: Boot.img from DXKT4

You need tool to unpack, repack boot.img
http://www.mediafire.com/?zdw766gu35o0fb6
Thank to ketut.kumajaya about his useful tool.
Extract to folder android
In Terminal

Code:

cd /home/[COLOR="red"]your username[/COLOR]/android/boot.img-tools

Now copy boot.img to folder called source_img in boot.img-tools folder above
Open Readme.txt
Follow the guide to extract boot.img
============================================================================================
After extract boot.img done

Code:

cd /home/[COLOR="Red"]your username[/COLOR]/android/GT-S5830_kernel/kernel

Code:

gedit Makefile

A text file open
Ctrl+F type: cross_compile
Find:

Code:

CROSS_COMPILE   =../../toolchain/arm-eabi-4.4.3/bin/arm-eabi-

Change to

Code:

CROSS_COMPILE   =../arm-2011.03/bin/arm-none-eabi-

Ctrl+S
Close

Code:

cd /home/[COLOR="Red"]your username[/COLOR]/android/boot.img-tools/boot/lib/modules

Code:

strings fsr.ko | grep vermagic

You'll see something like this

Code:

vermagic=2.6.35.7-perf-[COLOR="Red"]CL783107[/COLOR] preempt mod_unload ARMv6

Go to home/android/GT-S5830_kernel/kernel/arch/arm/configs
Find beni_rev01_defconfig open with gedit( double click to file > Display)
Find line

Code:

CONFIG_LOCALVERSION="-perf"

change to

Code:

CONFIG_LOCALVERSION="-perf-[COLOR="Red"]CL783107[/COLOR]"

The RED depends on your boot.img so it's diffirent the one from mine

GUIDE make kernel SUPPORT EXT2,3,4
Open beni_rev01_defconfig
find line "File systems" edit "# CONFIG_EXT3_FS is not set" to "CONFIG_EXT3_FS=y"

Code:

# File systems
#
CONFIG_EXT2_FS=y
CONFIG_EXT2_FS_XATTR=y
# CONFIG_EXT2_FS_POSIX_ACL is not set
# CONFIG_EXT2_FS_SECURITY is not set
# CONFIG_EXT2_FS_XIP is not set
# CONFIG_EXT3_FS is not set
[COLOR="Blue"]CONFIG_EXT4_FS=y[/COLOR]
CONFIG_EXT4_USE_FOR_EXT23=y
CONFIG_EXT4_FS_XATTR=y
# CONFIG_EXT4_FS_POSIX_ACL is not set
# CONFIG_EXT4_FS_SECURITY is not set
# CONFIG_EXT4_DEBUG is not set

Save and exit
Go to folder where boot.img extracted

Code:

cd /home/your username/android/boot.img-tools/boot/

Open init.rc with Gedit.
We a going to add mount point so system can mount EXT4 partition. By default, system only mount partition with RFS file system.Add red line to init.rc

Code:

# Mounting of /cache
[COLOR="Red"][B]mount ext4 /dev/block/stl14 /cache wait nosuid nodev noatime nodiratime noauto_da_alloc[/B][/COLOR]
mount rfs /dev/stl14 /cache nosuid nodev check=no

# Mounting of system/userdata is moved to 'on emmc' and 'on nand' sections
# We chown/chmod /data again so because mount is run as root + defaults
[COLOR="red"][B]mount ext4 /dev/block/stl13 /data wait nosuid nodev noatime nodiratime noauto_da_alloc[/B][/COLOR]
mount rfs /dev/stl13 /data nosuid nodev check=no

# Mount /system rw first to give the filesystem a chance to save a checkpoint
[COLOR="red"][B]mount ext4 /dev/block/stl12 /system ro wait noatime nodiratime noauto_da_alloc[/B][/COLOR]
mount rfs /dev/stl12 /system ro check=no

nice guide...

the tutorial was incomplete when i posted, so i thought you're teaching ubuntu installation.

asad007 · Jan 27, 2012

Very usefull indeed
btw can you tell me how to overclock the kernel??

zcop · Jan 28, 2012

Add OC and Undervolt Feature to kernel
GO to /home/Your username/android/GT-S5830_kernel/kernel/arch/arm/mach-msm/
Open acpuclock.c with Gedit
Find

Code:

static void acpuclk_set_div

and fix it like this

Code:

static void acpuclk_set_div(const struct clkctl_acpu_speed *hunt_s) 
{
      uint32_t reg_clkctl, reg_clksel, clk_div, src_sel, [B][COLOR="Blue"]a11_div[/COLOR][/B];
      reg_clksel = readl(A11S_CLK_SEL_ADDR);
      /* AHB_CLK_DIV */
      clk_div = (reg_clksel >> 1) & 0x03;
     /* CLK_SEL_SRC1NO */
     src_sel = reg_clksel & 1;
[B] [COLOR="blue"]    a11_div=hunt_s->a11clk_src_div;
     if(hunt_s->a11clk_khz>600000) {
     a11_div=0;
     writel(hunt_s->a11clk_khz/19200, MSM_CLK_CTL_BASE+0x33C);
     udelay(50);
}[/COLOR][/B]
/*
* If the new clock divider is higher than the previous, then
* program the divider before switching the clock
*/
........etc.......

Now find this line

Code:

/* 7x27 normal with GSM capable modem - PLL0 and PLL1 swapped */

Add

Code:

{ 1, 652800, ACPU_PLL_2, 2, 1, 200000, 2, [COLOR="Blue"][B]7[/B][/COLOR], 160000 },
{ 1, 768000, ACPU_PLL_2, 2, 2, 160000, 2, [COLOR="Blue"][B]7[/B][/COLOR], 160000 },
{ 1, 800000, ACPU_PLL_2, 2, 0, 200000, 3, [COLOR="Blue"][B]7[/B][/COLOR], 122880 },

after { 1, 600000, ACPU_PLL_2, 2, 1, 200000, 2, 7, 122880 }, and before { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, {0, 0, 0}, {0, 0, 0} }

The Blue column is set voltage for cpu. MSM7227 has voltage range from 1.2 to 1.35V as value 1 to 7.

Here is some Frequency if you 'd like to add more

Code:

{ 1, 652800, ACPU_PLL_2, 2, 1, 200000, 2, 7, 160000 }, 
{ 1, 691200, ACPU_PLL_2, 2, 1, 200000, 2, 7, 160000 }, 
{ 1, 710400, ACPU_PLL_2, 2, 1, 200000, 2, 7, 160000 }, 
{ 1, 729600, ACPU_PLL_2, 2, 1, 200000, 2, 7, 160000 }, 
{ 1, 748800, ACPU_PLL_2, 2, 1, 200000, 2, 7, 160000 }, 
{ 1, 768000, ACPU_PLL_2, 2, 1, 200000, 2, 7, 160000 }, 
{ 1, 787200, ACPU_PLL_2, 2, 2, 160000, 2, 7, 160000 }, 
{ 1, 800000, ACPU_PLL_0, 4, 0, 206400, 3, 7, 122880 },
{ 1, 806400, ACPU_PLL_2, 2, 2, 160000, 2, 7, 160000 }, 
{ 1, 825600, ACPU_PLL_0, 4, 0, 206400, 3, 7, 122880 },
{ 1, 844800, ACPU_PLL_0, 4, 0, 211200, 3, 7, 122880 },
{ 1, 864000, ACPU_PLL_0, 4, 0, 216000, 3, 7, 122880 },

AND another Freq provide by pratyush.creed

Code:

	{ 1, 600000, ACPU_PLL_2, 2, 1, 200000, 2, 7, 122880 },
 	{ 1, 614400, ACPU_PLL_2, 2, 0, 153600, 3, 6, 122880 },
 	{ 1, 672000, ACPU_PLL_2, 2, 0, 168000, 3, 6, 122880 },
 	{ 1, 729600, ACPU_PLL_2, 2, 0, 182400, 3, 7, 122880 },
	{ 1, 800000, ACPU_PLL_2, 2, 0, 200000, 3, 7, 122880 },

Due to some isues about not set default Freq that make phone run at max Freq as default. Here
Open beni_rev01_defconfig find line

Code:

# CONFIG_MSM_CPU_FREQ_SET_MIN_MAX is not set

change to

Code:

CONFIG_MSM_CPU_FREQ_SET_MIN_MAX=y

And add this below CONFIG_MSM_CPU_FRQ_MIN_MAX

Code:

CONFIG_MSM_CPU_FREQ_MAX=600000
CONFIG_MSM_CPU_FREQ_MIN=245000

nope

just change this line
# CONFIG_EXT4_FS is not set

to

CONFIG_EXT4_FS=y

zcop · Jan 29, 2012

no, you should uncomment it ( del the # symbol)
set value to it
EX: # CONFIG_EXT4_FS is not set >>> CONFIG_EXT4_FS=y

Thank's sir...n your thread is really2 helpfull for a noob like me....

*thank's button has been pressed..*

sakindia123 · Jan 30, 2012

i believe there's a mistake.

Code:

CROSS_COMPILE   =../arm-2011.03/bin/arm-none-eabi-

should be

Code:

CROSS_COMPILE   =../arm-2011.03/bin/arm-none-linux-gnueabi-

Repack Ramdisk and Compile zImage

Go to /home/android/GT-S5830_kernel/kernel
Double click on make_kernel_GT-S5830.sh> Display
Change

Code:

make cooper_rev03_defconfig

to

Code:

make beni_rev01_defconfig

Save and exit
In Terminal

Code:

cd /home/[COLOR="Red"]your username[/COLOR]/android/GT-S5830_kernel/kernel

Code:

./make_kernel_GT-S5830.sh

take a cup of coffee
(15-20m)
Now you get your kernel. It's zImage
Take zImage from /home/android/GT-S5830_kernel/kernel/arch/arm/boot copy to /home/android/boot.img-tools/unpack
Del old boot.img-zImage

Repack new Ramdisk

Code:

cd /home/[COLOR="Red"]your username[/COLOR]/android/boot.img-tools/

Code:

tools/mkbootfs boot | gzip > unpack/boot.img-ramdisk.gz

Repack boot.img

Code:

 cd /home/[COLOR="Red"]your username[/COLOR]/android/boot.img-tools/

Code:

tools/mkbootimg --kernel unpack/zImage --ramdisk unpack/boot.img-ramdisk.gz -o target_img/boot.img --base `cat unpack/boot.img-base`

If you want flash boot.img through download mode

Code:

cd /home/[COLOR="Red"]your username[/COLOR]/android/boot.img-tools/target_img

Code:

tar cvf boot.tar boot.img

Or you can make CWM zip

Now taste your work:
