How to compile kernel from source for Sony Xperia L
Things needed :
A PC
Ubuntu on VM or Main Os
Android Phone/Tab
, In this case XL unlocked
Brain (Be sure you get it).
I suggest to get Hells-Kitchen Ubuntu distro it has all the basic things installed for compiling kernels/modding/and ROMS.
Distro Link : http://xdaforums.com/showthread.php?t=2152398
> Then proceed further by getting the opensource archives from Sony developer website.
> I suggest you to download within Ubuntu distro for ease.
> Extract it.
> Now we need to setup and fix some sh*ts before we can rven think of compiling.
> To start of setup the toolchains, In my case I used Linaro you can use the ones posted here

> Then setup the toolchains in your Makefile.
> Now the real work begins we need to fix the source before compilation.

> Pack your kernel get all the modules search for .ko files.
> Flash you kernel with Fastboot mode.
> Flash your modules or replace them manually and set permissions accordingly.
> You are done with your kernel if all goes well Xperia Should boot up
