hello folks!

i have been working on kernels for various xperia devices since the Xperia X10... i will update this thread with information on how to build kernels for various xperia devices...


Sony (Ericsson) started off helping the developer community with information on how to build kernels:
http://developer.sonymobile.com/2011/05/06/how-to-build-a-linux-kernel/

do read the above post, though its slightly old (2011), its really good! Since then Sony has released various devices which use a variety of chipsets and each chipset has different ways to build bootable kernel...

the objective of this thread is to provide brief instructions for some of these chipsets across the various device generations to build bootable kernels...

this will not cover how to build working ramdisks... you can always use the stock ramdisks from kernel.sin... here is how to get stock ramdisk out from kernel.sin...




Toolchains:

I have tested various toolchains for building kernels and very few work correctly on the kernel sources to get bootable kernel.

The toolchains which worked for me are:
  • arm-eabi-4.4.3 - GCC 4.4.3 toolchain from CyanogenMod repo
  • arm-eabi-linaro-4.6.2 - GCC Linaro 4.6.2 (2011.10) toolchain
  • arm-linux-androideabi-4.7 - GCC 4.7 from Google repo

all of these are posted on my git repo:
https://github.com/DooMLoRD/android_prebuilt_toolchains

sometimes the kernel sources need to be modified slightly to support compiling using these toolchains. I have mentioned the necessary patches where-ever applicable.




Instructions for various generation of devices:

Xperia 2014 (H1) - msm8974ab - Xperia Z2

Xperia 2013 (H2) - msm8974 - Xperia Z1, Z Ultra, Z Ultra GPe, Z1 Compact

Xperia 2013 (H1) - apq8064 - Xperia Z, ZL, ZR, Tablet Z

Xperia 2013 (H1) - msm8960t - Xperia SP

Xperia 2012 (H2) - msm8960 - Xperia T, TX, V

Xperia 2012 (H1) - msm8660 - Xperia S, SL, Ion, Acro S

Xperia 2011 - msm8x55/msm7x30 - Xperia Arc, Play, Neo, Ray, etc

Recommended toolchain:
GCC 4.6 Linaro


Fix Makefile for 4.6 Toolchain:
Code:
KBUILD_CFLAGS   := -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs \
       -Werror \

Supported boards on this platform:

  • zeus - Xperia Play, Xperia L
  • mogami - Xperia Arc, Arc S, Ray, Neo, etc


Building kernel (zImage):

for Xperia Arc (anzu):
import defconfig
Code:
ARCH=arm CROSS_COMPILE=~/android-toolchain-eabi-linaro-4.6-2011.10/bin/arm-eabi- make semc_anzu_defconfig

for Xperia Play (zeus):
import defconfig
Code:
ARCH=arm CROSS_COMPILE=~/android-toolchain-eabi-linaro-4.6-2011.10/bin/arm-eabi- make semc_zeus_defconfig


build zImage
Code:
ARCH=arm CROSS_COMPILE=~/android-toolchain-eabi-linaro-4.6-2011.10/bin/arm-eabi- make  -j8




Instructions for building boot.img


first get the kernel built... once kernel is built u will get zImage and copy that zImage to the folder containing the build tools...

i have posted the build tools i use here:
https://github.com/DooMLoRD/build_tools/tree/master/msm7x30_mogami_zeus


Sony used the standard boot.img format for this chipset devices


building boot.img

use the following command:
Code:
./mkbootimg --base 0x00200000 --kernel zImage --ramdisk ramdisk.cpio.gz -o boot.img




Special notes

  • Sometimes the compiled kernel will just not boot, will show blank screen. Workaround is, ramdisks needs to be filled with filler so that total size is bigger.
  • boot.img can be hotbooted (fastboot boot boot.img)

Recommended toolchain:
GCC 4.7



Fixes for 4.7 Toolchain:

Makefile fix

defconfig fix



Supported boards on this platform:

  • fuji- Xperia S, SL, Ion, Acro S



Building kernel (zImage):

for Xperia S (nozomi):

Instructions for building kernel.elf

first get the kernel built... once kernel is built u will get zImage and copy that zImage to the folder containing the build tools...

i have posted the build tools i use here:
https://github.com/DooMLoRD/build_tools/tree/master/msm8660_fuji


Sony shifted to ELF format for this chipset...

They had posted instructions on there website:
http://developer.sonymobile.com/201...-archive-released-with-building-instructions/
(avoid using those files as they are for GingerBread)


building kernel.elf

use the following command (for JB):
Code:
python mkelf.py -o kernel.elf [email protected] [email protected],ramdisk [email protected],rpm

the additional files required are posted at my build tools repo



Special notes

  • RPM is different for each device and also differs for OS release, so the same RPM wont work on Xperia S or Xperia Ion and GB/ICS/JB each have different RPMs
  • kernel.elf CANNOT be hotbooted (fastboot boot kernel.elf)

building boot.img

MSM8974 needs something new to build a kernel, this is called a dt.img. This basically is an img file which holds information about the board pagesize, kernel version and some other kernel related things. You can only use a specific dt.img with a kernel, this file needs to be generated by a binary called dtbTool. This binary can be found in the Cyanogen repo's or you can download a prebuild one in this thread.

to get the dt.img:
Code:
# path to kernel sources
KERNEL_SRC_PATH=~/android_kernel_sony_msm8974/

echo "generating device tree..."
./dtbTool -o dt.img -s 2048 -p {KERNEL_SRC_PATH}/scripts/dtc/ {KERNEL_SRC_PATH}/arch/arm/boot/

once u have the dt.img along with the zImage and ramdisk.cpio.gz use the following command:
Code:
./mkbootimg --base 0x00000000 --kernel zImage --ramdisk_offset 0x02000000 --tags_offset 0x01E00000 --pagesize 2048 --cmdline "androidboot.hardware=qcom user_debug=31 maxcpus=2 msm_rtb.filter=0x3F ehci-hcd.park=3 msm_rtb.enable=0 lpj=192598 dwc3.maximum_speed=high dwc3_msm.prop_chg_detect=Y" --ramdisk ramdisk.cpio.gz --dt dt.img -o boot.img


corrected build tools are posted at my build tools repo



Special notes

  • boot.img CAN be hotbooted (fastboot boot boot.img)

Hello doom,I want to ask you something.I manage to port your doomkernel v22 GB for Arc/Arc S to Neo/Neo V and I want permissions from you to share it in Neo forum.Sorry for asking here, but you don't answer me on the PM that I send you.

Sorry for my English.

Great tutorial! But I came across a problem:when compiling a CM kernel for Xperia TX,I need to change the command from
Code:
python mkelf.py -o kernel.elf [email protected] [email protected][COLOR="red"]4[/COLOR]00000,ramdisk [email protected],rpm [email protected],cmdline

to
Code:
python mkelf.py -o kernel.elf [email protected] [email protected][COLOR="red"]7[/COLOR]00000,ramdisk [email protected],rpm [email protected],cmdline

Otherwise the phone won't boot.Only black screen with backlight on and then reboot after pressing the power button,even no Sony/CM logo.

(Another strange case:when I use sksplit to split the official kernel,the ramdisk does lay in 0x81400000.But if I import the hayabusa_defconfig,compile the kernel from Sony source without any change and mkelf with official [email protected],the phone still refuses to boot.I have to change the 4 to 7 to make this kernel boot.Why?)
