# raspberrypi-kernel

English | [简体中文](./README.md)

#### Description

The kernel for running on Raspberry Pi.

This repository is based on [openEuler kernel](https://gitee.com/openeuler/kernel) which is merged patches of [Raspberry Pi kernel](https://github.com/raspberrypi/linux).

#### Architecture Requirements

Hardware: Raspberry Pi 3B/3B+/4B.

Architecture: AArch64.

#### Compiling

Compile kernel and kernel modules.

1.  Prepare compile environment

    OS: openEuler or CentOS 7/8;

    Architecture: AArch64.

    You follow the documents of [raspberrypi](https://gitee.com/openeuler/raspberrypi/blob/master/README.en.md) to cross-compile this kernel.

2.  Download source

    You need download different branches of different repositories according to the kernel version.

    1.  Kernel 5.10

        - openEuler 21.09: `git clone git@gitee.com:openeuler/raspberrypi-kernel.git -b openEuler-21.09 && cd raspberrypi-kernel`
        - openEuler 21.03: `git clone git@gitee.com:openeuler/kernel.git -b openEuler-21.03 && cd kernel`

    2.  Kernel 4.19

        - openEuler 20.03 LTS: `git clone git@gitee.com:openeuler/raspberrypi-kernel.git -b openEuler-20.03-LTS && cd raspberrypi-kernel`
        - openEuler 20.09: `git clone git@gitee.com:openeuler/raspberrypi-kernel.git -b openEuler-20.09 && cd raspberrypi-kernel`

3.  Load default settings

    You need load different settings according to the kernel version.

    1.  Kernel 5.10

        - openEuler 21.09: `make bcm2711_defconfig`
        - openEuler 21.03: `make bcm2711_defconfig`

    2.  Kernel 4.19

        - openEuler 20.03 LTS: `make openeuler-raspi_defconfig`
        - openEuler 20.09: `make openeuler-raspi_defconfig`

    The corresponding defconfig file is in . /arch/arm64/configs.

4.  Compile kernel

    `make ARCH=arm64 -j4`

5.  Create directory for compiling kernel modules

    `mkdir ../output`

6.  Compile kernel modules

    `make INSTALL_MOD_PATH=../output/ modules_install`

Now, the kernel compilation is complete.

#### Installation
