Downloading sources
Download the source for the kernel you want to build using the appropriate
git clone command. For example, the following command clones the
hikey kernel, used for the HiKey reference boards:
git clone https://android.googlesource.com/kernel/hikey-linaro
A full list of kernel projects can be found in the
kernel directory. Below
are some of the commonly used kernels and their respective git clone
commands.
The exynos project has the kernel sources for Nexus 10, and can
be used as a starting point for work on Samsung Exynos chipsets.
git clone https://android.googlesource.com/kernel/exynos
The goldfish project contains the kernel sources for the
emulated platforms.
git clone https://android.googlesource.com/kernel/goldfish
The hikey-linaro project is used for HiKey reference boards,
and can be used as a starting point for work on HiSilicon 620 chipsets.
git clone https://android.googlesource.com/kernel/hikey-linaro
The msm project has the sources for ADP1, ADP2, Nexus One,
Nexus 4, Nexus 5, Nexus 6, Nexus 5X, Nexus 6P, Nexus 7 (2013), Pixel, and
Pixel XL, and can be used as a starting point for work on Qualcomm MSM chipsets.
git clone https://android.googlesource.com/kernel/msm
The omap project is used for PandaBoard and Galaxy Nexus, and
can be used as a starting point for work on TI OMAP chipsets.
git clone https://android.googlesource.com/kernel/omap
The samsung project is used for Nexus S, and can be used as a
starting point for work on Samsung Hummingbird chipsets.
git clone https://android.googlesource.com/kernel/samsung
The tegra project is for Xoom, Nexus 7 (2012), and Nexus 9, and can
be used as a starting point for work on NVIDIA Tegra chipsets.
git clone https://android.googlesource.com/kernel/tegra
The x86_64 project has the kernel sources for Nexus Player, and
can be used as a starting point for work on Intel x86_64 chipsets.
git clone https://android.googlesource.com/kernel/x86_64
Building the kernel
If you don't intend to build the default branch (for example, master), you
need to check out the desired commit before building. See
Identifying kernel versions for how to
identify the kernel version of a prebuilt kernel binary. Now you're ready
to build the kernel. The following build commands use the hikey kernel:
cd hikey-linaroexport ARCH=arm64export CROSS_COMPILE=aarch64-linux-android-make hikey_defconfigmake
To build a different kernel, simply replace hikey-linaro with
the name of the kernel you want to build and hikey_defconfig
with the name of the corresponding defconfig file.
The image outputs to the arch/arm64/boot/ directory; the
kernel binary outputs to the
arch/arm64/boot/dts/hisilicon/hi6220-hikey.dtb file. Follow the
instructions in
Running the kernel for how
to embedd the freshly built kernel into your AOSP image.
