Linux Kernel source code for the devices:

• bq aquaris M10 FHD

Specific sources are separated by branches and each version is tagged with it's corresponding number. First, you should clone the project:

    $ git clone https://github.com/bq/aquaris-M10-FHD.git

After it, choose the version you would like to build:

• Aquaris M10 FHD *

    $ mv aquaris-M10-FHD kernel
    $ cd kernel
    $ git checkout aquaris-M10-FHD_2.x
  

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 marshmallow-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:

    $ make -C kernel  O=../KERNEL_OUT  ARCH=arm64 CROSS_COMPILE=../aarch64-linux-android-4.9/bin/aarch64-linux-android- {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
