Rust 官方并没有为 riscv64gc-unknown-none-elf 这个 target 提供标准库 std,而只有核心库 core 。所以是因为现在 build 的项目用到了标准库 std 才出现了这个问题,详情参考文档第一章第二小节的 移除标准库依赖

M1 MacbookPro 正常启动 Qemu 安装:

执行:

brew install ninja glib pixman pkg-config texinfo nettle gettext libffi
git clone https://github.com/patchew-project/qemu
cd qemu

然后需要加一个补丁,以避免qemu-system-riscv: qemu_mprotect__osdep: mprotect failed: Permission denied的问题。

// util/osdep.c 
// 在 int qemu_mprotect_none(void *addr, size_t size) 函数中加入 m1 平台判断

int qemu_mprotect_none(void *addr, size_t size)
{
#ifdef _WIN32
    return qemu_mprotect__osdep(addr, size, PAGE_NOACCESS);
#elif defined(__APPLE__) && defined(__arm64__)
    /* Workaround mprotect (RWX->NONE) issue on Big Sur 11.2 */
    return 0;
#else
    return qemu_mprotect__osdep(addr, size, PROT_NONE);
#endif
}

开始构建:

mkdir build && cd build
../configure --target-list=riscv64-softmmu,aarch64-softmmu --extra-cflags=-I/opt/homebrew/opt/gnutls/include --extra-ldflags=-L/opt/homebrew/opt/gnutls/lib --enable-cocoa
make -j
sudo make install

构建完毕,注意设置 qemu 的 PATH 为 build 目录。

以上。应该就可以在 M1 上正常使用 Qemu 了。

rust安装脚本中toolchain需要手动选择nightly,否则默认安装的为default版本

可以通过在项目根目录下添加写有 nightlyrust-toolchain 文件实现本项目使用 nightly 版本,而非 stable 版本。这样的话,电脑上会同时存在两个版本。

@imjustfly 你是在用m1 吗? Could not allocate dynamic translator buffer这个错误是需要打patch的。你可以看看我上面评论里的那个方法重装一下qemu。然而那个patch也是针对 5.2.50最新版本的。总之目前还不如用docker。

Q:windows下可以开展OS实验的方便环境吗?
A:可以的,有两种方式:

  1. 安装wsl2和vscode,在wsl2上安装ubuntu 20.04,并进一步根据本章描述在ubuntu上安装相关软件;在vscode安装Remote - WSL,Rust Analyzer等插件。就可以在vscode上编辑/分析位于wsl2的ubuntu 20.04中的代码文件了
  2. 安装wsl2和clion,在wsl2上安装ubuntu 20.04,并进一步根据本章描述在ubuntu上安装相关软件(包括xfce4 GUI环境,clion IDE for linux);安装VcXsrv(xserver in win)。这样就可以在VcXsrv提供的图形界面下用clion IDE编辑/分析位于wsl2的ubuntu 20.04中的代码文件了

注:编译运行一般在命令行通过 make run等完成。

Copy link

安装WSL2应该不需要加入预览体验计划吧

@imjustfly
Copy link

@ZhangHanDong M1 没错。你上面那个手动的patch是修复M1 macos 11.2 下的 mprotect问题,Could not allocate dynamic translator buffermmap问题,这个在5.2.50版本才修复,之前的版本都不行。

然而,rustsbi表示必须在5.1以下的qemu中使用:

https://github.com/luojia65/rustsbi/issues/12#issuecomment-784900685

所以,我也懒得研究把5.2.50中对于mmap syscall的使用的修改port到5.1去了,毕竟只是一时兴起想学习一下这个项目,我还是直接docker或者ssh 一个linux主机吧。

ZhangHanDong commented Feb 25, 2021

VMware虚拟机方式应该是最省心的了,你只需要下好Ubuntu 22.04的iso文件,下载本文提供的虚拟磁盘文件,新建虚拟机时注意选择磁盘文件,就能直接打开了
然后一行官方脚本配好rust
在Downloads文件夹里找到下好的qemu,根据本文操作
就可以了

个人在ArchLinux下尝试配置qemu环境和实验环境,只需要

$ sudo pacman -S qemu-full

一条命令即可,这个安装的版本是8.0.1的(2023.9.19),之后直接在clone下的rCore-Tutorial-v3的os目录下进行make run即可,我能够直接输出RustSBI图样及Rust user_shell的那些应用。

至于之前的riscv环境和rust环境按照教程即可,唯一不同的是安装riscv-elf-gdb,没有中间那个unknown字样,这些可以在extra仓库里搜索到。

在 "GDB 调试支持" 一节提到:

我们推荐使用 gdb-dashboard 插件,可以大大提升调试体验。

如若默认使用 riscv64-unknown-elf-toolchainbin 文件夹下的预编译文件,应当将所有出现于 Makefile文件 中的 riscv64-unknown-elf-gdb 替换成 riscv64-unknown-elf-gdb-py 以启用 Python 支持,否则的话由 gdb-dashboard 提供的 .gdbinit 并未生效,该细节建议进行补充。

@kidcats 转载你的原始内容,便于在GitHub Issue中搜索,谢谢你的贡献。 补一个vscode远程调试的方法 1.先在os路径下执行,make debugserver,开启远程调试 2. 配置launch.json

    "configurations": [
        {
            "type": "cppdbg",
            "request": "launch",

能不能帮忙提供一份支持python的gdb

一、如果想用gdb-dashboard插件的话,只是将所有出现于 Makefile文件 中的 riscv64-unknown-elf-gdb 替换成 riscv64-unknown-elf-gdb-py可能不太行(至少我没有成功,插件依然使用不了,另外我的环境是ubuntu20.04,python版本为python2.7、python3.8)

二、可以选择自行编译riscv64-unknown-elf-gdb,就按照 https://rcore-os.cn/rCore-Tutorial-deploy/docs/pre-lab/gdb.html 提供的方法(亲测行得通)

三、不过按照这个网站编译的话需要注意一下几点

1、用python2环境

2、不要编译版本太高的gdb,我最初选择编译的是gdb14.1,莫名报错编译失败,后来使用gdb10.1版本源码编译就成功了

四、这是我在我上面提到的环境下编译好的支持gdb-dashboard插件的gdb, 希望对你有所帮助
