Linux Kernel source code for the devices:
- Sony XPERIA L1
Specific sources are separated by releases with it's corresponding number. First, you should clone the project:
$ git clone -b cm-14.1 https://github.com/PineDevelopment/kernel_sony_pine.git kernel
At the same level of the "kernel" directory:
Download a prebuilt gcc
$ git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9 -b nougat-release
Create KERNEL_OUT dir:
$ mkdir KERNEL_OUT
Your directory tree should look like this:
- kernel
- aarch64-linux-android-4.9
- KERNEL_OUT
Finally, build the kernel according the next table of product names:
| device | product |
|---|---|
| Sony XPERIA L1 | pine |
$ make -C kernel O=../KERNEL_OUT ARCH=arm64 CROSS_COMPILE=../aarch64-linux-android-4.9/bin/aarch64-linux-android- pine_defconfig
$ make O=../KERNEL_OUT/ -C kernel ARCH=arm64 CROSS_COMPILE=../aarch64-linux-android-4.9/bin/aarch64-linux-android-
You can specify "-j CORES" argument to speed-up your compilation, example:
$ make O=../KERNEL_OUT/ -C kernel ARCH=arm64 CROSS_COMPILE=../aarch64-linux-android-4.9/bin/aarch64-linux-android- -j 8
