Overview + +The `loongarch64_virt/linux` directory contains code that has been verified on the QEMU LoongArch64 Virt platform for adapting to Linux kernel. The code includes the driver and board configurations. + +The LoongArch64 Virt platform is a `qemu-system-loongarch64` target device that simulates a general-purpose board running on the LoongArch64 architecture. +The board whose **machine** is **virt** in QEMU is configurable. For example, you can select the core type and quantity, memory size, and security extensions when configuring the board. + +This tutorial guides you through the configuration of a board based on the LoongArch 64 architecture, with one CPU, extended secure features, Generic Interrupt Controller versions 2 (GICv2), and 1 GB memory. +The system memory is hardcoded to 1024 MB. + +## 2.

Therefore, you must ensure that the qemu-system-loongarch64 version is 8.0 or later. + + +b) Run the images. + +After the source code is built, run the `./vendor/ohemu/qemu_loongarch64_linux_min/qemu_run.sh` or `./vendor/ohemu/qemu_loongarch64_linux_headless/qemu_run.sh` command, the images built in step 4 will be started. + +c) Exit QEMU. + +Press `Ctrl-A + x` to exit the QEMU virtual environment. diff --git a/loongarch64_virt/linux/README_zh.md b/loongarch64_virt/linux/README_zh.md new file mode 100755 index 0000000..fd0099f --- /dev/null +++ b/loongarch64_virt/linux/README_zh.md @@ -0,0 +1,107 @@ +# Qemu LoongArch64 Virt 标准系统教程 + +## 1. 简介 + +`loongarch64_virt/linux` 子目录包含部分Qemu LoongArch 64虚拟化平台验证的Linux kernel的适配代码，含驱动配置、板端配置等。 + +LoongArch64 虚拟化平台是一个 `qemu-system-loongarch64` 的目标设备，通过它来模拟一个通用的、基于龙架构的单板。 + +Qemu中machine为 **virt** 的单板就是这种可配置的，例如：选择核的类型、核的个数、内存的大小和安全特性等，单板设备的配置。 + +这次模拟的配置是：LoongArch 64架构，1个CPU，带安全扩展，1G内存。 + +提示: 系统内存硬编码为1024MB。 + +## 2. 环境搭建 + +参考链接: [环境搭建](https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/porting/Readme-CN.md) + +## 3. 获取源码 + +参考链接: [代码获取](https://gitee.com/openharmony/docs/blob/HEAD/zh-cn/device-dev/get-code/sourcecode-acquire.md) + +## 4. 源码构建 + +在已经获取的源码根目录，请输入： + +``` +./build.sh --product-name qemu-loongarch64-linux-min --ccache --jobs 4 +``` + +在构建完成之后，对应的镜像文件在out/qemu-loongarch64-linux/packages/phone/images/目录下。 + +`qemu-loongarch64-linux-min` 表示部件最小集合的产品。 + + +## 5. 在Qemu中运行镜像 + +a) 如果没有安装 `qemu-system-loongarch64` ，安装请参考链接 [Qemu installation](https://gitee.com/openharmony/device_qemu/blob/HEAD/README_zh.md) + +提示：当前引入的功能在virt-8.0的目标machine已经完成测试，不保证所有的Qemu版本都能够运行成功，因此需要保证你的qemu-system-loongarch64 版本尽可能在8.0及以上。 + +b) 运行镜像 + +执行`./vendor/ohemu/qemu_loongarch64_linux_min/qemu_run.sh`或`./vendor/ohemu/qemu_loongarch64_linux_headless/qemu_run.sh`即可运行步骤4生成的镜像。 + +c) 退出qemu环境 + +按下`Ctrl-A + x`可退出qemu虚拟环境。 + +### 5.1 qemu_run.sh使用说明 + +```C +Usage: qemu-run [OPTION]... +Run a OHOS image in qemu according to the options. + -e, --exec image_path images path, including: zImage-dtb, ramdisk.img, system.img, vendor.img, userdata.img + -g, --gdb enable gdb for kernel. + -n, --network auto setup network for qemu (sudo required). + -i, --instance id start qemu images with specified instance id (from 01 to 99). + it will also setup network when running in multiple instance mode. + -f force override instance image with a new copy. + -h, --help print this help info. + + If no image_path specified, it will find OHOS image in current working directory;
