Linux Kernel source code for the devices:
- bq aquaris X
Specific sources are separated by releases with it's corresponding number. First, you should clone the project:
$ git clone https://github.com/bq/aquaris-X.git
After it, choose the release you would like to build:
Aquaris X
$ mv aquaris-X kernel
$ cd kernel
$ git checkout tags/{release}
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
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 |
|---|---|
| bq aquaris X | bardock |
$ make -C kernel O=../KERNEL_OUT ARCH=arm64 CROSS_COMPILE=../aarch64-linux-android-4.9 {product}_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
