The host runs QEMU +with HVF, boots an AArch64 StarryOS SMP guest, and runs guest `cargo build` to +build StarryOS again inside StarryOS. + +The normal reproduction path builds the rootfs locally on macOS and does not use +Docker. `build_rootfs.sh` creates the AArch64 Alpine guest rootfs, installs the +pinned guest Rust/Cargo toolchain, prefetches the offline Cargo cache, and +injects the current TGOSKits source tree. + +## What This Demonstrates + +- host: Apple Silicon macOS; +- accelerator: QEMU HVF; +- guest kernel: StarryOS AArch64 SMP kernel; +- guest workload: StarryOS guest runs Cargo and builds the `starryos` binary; +- stable build shape: 8-vCPU guest with eight Cargo jobs (`SMP=8 JOBS=8`); +- pass marker: `===STARRY-MACOS-SELFBUILD-PASS jobs= elapsed====`. + +The default reproduction proves that the StarryOS SMP guest can complete a +self-build while booted with 8 vCPUs and running Cargo with eight jobs. + +Using AArch64/HVF keeps the guest ISA aligned with the Mac host CPU. This avoids +the cross-ISA TCG cost of RISC-V-on-macOS experiments and makes the self-build +result practical to reproduce on a laptop. + +## Prerequisites + +```bash +brew install qemu e2fsprogs zig llvm +``` + +The scripts use: + +- `qemu-system-aarch64`; +- `debugfs` from Homebrew `e2fsprogs`; +- `zig` or an `aarch64-linux-musl-gcc` cross compiler for the seed kernel; +- `llvm-nm` and `llvm-objdump`, with Homebrew `llvm` used as fallback. + +The generated self-build rootfs contains the guest Rust/Cargo toolchain, +offline Cargo dependencies, and a TGOSKits source tarball. `check_rootfs.sh` +verifies the minimum paths. + +## Reproduce From a Fresh Clone + +Clone and enter the branch under test: + +```bash +git clone https://github.com/yks23/tgoskits.git +cd tgoskits +git checkout app/starry-macos-selfbuild +``` + +Run the complete reproduction on macOS: + +```bash +RUST_DIST_SERVER=https://rsproxy.cn \ +STARRY_CARGO_REGISTRY_INDEX=sparse+https://rsproxy.cn/index/ \ +apps/starry/macos-selfbuild/reproduce.sh +``` + +The mirror variables are optional. Omit them to use the official Rust and +crates.io endpoints, or set them to closer mirrors when `static.rust-lang.org` +or `index.crates.io` is slow. + +`reproduce.sh` runs the three required steps: build or refresh the rootfs, build +the seed kernel, and launch the QEMU HVF self-build. On a base M1 with 8 GB +memory, close other heavy applications before running the 8-vCPU case; if it is +memory pressured, first verify the setup with: + +```bash +SMP=4 JOBS=4 MEM=3072M \ +RUST_DIST_SERVER=https://rsproxy.cn \ +STARRY_CARGO_REGISTRY_INDEX=sparse+https://rsproxy.cn/index/ \ +apps/starry/macos-selfbuild/reproduce.sh +``` + +The rootfs build downloads Alpine AArch64 APKs and Rust nightly components, then +runs `cargo fetch` on the host to populate the guest offline cache. The +`cargo fetch` phase may print only `Updating crates.io index` for several +minutes while the sparse registry cache is being populated. + +For reproducibility, the default native rootfs payload is pinned to Alpine +`v3.23` and Rust `nightly-2026-05-28`. Do not switch `ALPINE_BRANCH=edge` for +the graded reproduction: Alpine edge currently provides a newer Cargo/Rust +package set and can change the build-std schedule substantially. + +The expected output ends with: + +```text +STARRY_MACOS_SELFBUILD_ROOTFS_OK +``` + +After every `git pull`, branch switch, or source edit, refresh the source +payload embedded in the rootfs before running QEMU: + +```bash +apps/starry/macos-selfbuild/prepare_rootfs.sh +``` + +`run_selfbuild.sh` checks `/opt/tgoskits-src.meta` by default and exits early if +the rootfs was built from a different commit. This avoids accidentally running +an old rootfs for an hour. Set `REQUIRE_FRESH_ROOTFS=0` only for deliberate +stale-rootfs experiments. + +If a prebuilt rootfs artifact is supplied, it can still be placed at the +standard path instead of rebuilding locally. Use either a local downloaded file: + +```bash +apps/starry/macos-selfbuild/fetch_rootfs.sh \ + --input /path/to/rootfs-aarch64-hvf-selfbuild.img +``` + +or a direct artifact URL: + +```bash +ROOTFS_URL='https://.../rootfs-aarch64-hvf-selfbuild.img' \ +apps/starry/macos-selfbuild/fetch_rootfs.sh +``` + +Build the seed StarryOS kernel on macOS: + +```bash +apps/starry/macos-selfbuild/build_kernel.sh +``` + +Run the complete 8-vCPU, eight-Cargo-job self-build: + +```bash +KERNEL=target/aarch64-unknown-none-softfloat/release/starryos.bin \ +ROOTFS=tmp/axbuild/rootfs/rootfs-aarch64-hvf-selfbuild.img \ +SMP=8 \ +JOBS=8 \ +RAYON_NUM_THREADS=1 \ +RUSTC_THREADS=2 \ +SOURCE_TMPFS=1 \ +QEMU_TIMEOUT_SEC=10800 \ +apps/starry/macos-selfbuild/run_selfbuild.sh +``` + +A successful run prints: + +```text +===STARRY-MACOS-SELFBUILD-QEMU-AARCH64-PROFILE expected_crates~420=== +===STARRY-MACOS-SELFBUILD-PASS jobs=8 elapsed==== +===STARRY-MACOS-SELFBUILD-RUN-END rc=0=== +``` + +The qemu-aarch64 reproducible profile should show: + +```text +rustc_threads=2 +features=plat-dyn,ax-driver/virtio-blk,ax-driver/virtio-net,ax-driver/virtio-gpu,ax-driver/virtio-input,ax-driver/virtio-socket,starry-kernel/input,starry-kernel/vsock +``` + +The guest refuses a run whose `RUSTC_THREADS` differs from `2` unless +`ALLOW_SLOW_SELFBUILD=1` is explicitly set. This keeps the graded run on the +same qemu-aarch64 profile that was debugged for reproducibility. + +The host runner also refuses unexpectedly large Cargo totals by default. The +current qemu-aarch64 profile is expected to report about `420` Cargo units. A much larger +total usually means a stale rootfs or slow feature set is being used; refresh the +rootfs from the current checkout and rerun the command above. + +Logs are written under: + +```text +target/starry-macos-selfbuild/logs/ +``` + +The runner copies the input rootfs into +`target/starry-macos-selfbuild/rootfs/`, injects the guest runner scripts, and +runs QEMU against that working copy, so the input artifact is not modified.

CPU 占用不符合预期 + +QEMU 暴露给 guest 的 vCPU 数是 `SMP=8`，Cargo job 数是 `JOBS=8`，但 macOS +活动监视器看到的总 CPU 占用并没有打满 8 核。这个现象本身不是单独的 bug， +它说明 guest 内部存在串行瓶颈或阻塞点，vCPU 数量并不等于宿主机会持续满载。 + +后续从日志看，主要瓶颈不是 QEMU 没分配 CPU，而是 guest 里的文件系统写入、 +元数据同步、kallsyms 处理、以及部分 kernel/runtime 逻辑问题。 + +### 3. 编译 profile 和启动 profile 不一致 + +一开始尝试过较“瘦”的 defplat/静态 profile，但它和普通 +`cargo xtask starry qemu --arch aarch64` 使用的 qemu-aarch64 动态平台路径不一致。 + +真正要验证的 kernel 应该按 qemu-aarch64 board 的动态平台特性构建，也就是： + +```text +plat-dyn, +ax-driver/virtio-blk, +ax-driver/virtio-net, +ax-driver/virtio-gpu, +ax-driver/virtio-input, +ax-driver/virtio-socket, +starry-kernel/input, +starry-kernel/vsock +``` + +同时 AArch64 这条路径应走 PIE JSON target spec，而不是旧的静态 `defplat` +linker script 路径。 + +### 4. guest 内缺少 kallsyms 所需工具 + +guest 编译出 `starryos` 后，还需要跑 `starry-kallsyms.sh`，这一步依赖： + +- `rust-nm` +- `rust-objdump` +- `rust-objcopy` +- `gen_ksym` + +guest rootfs 内不一定直接有这些 Rust binutils 工具。之前即使 Cargo build 过了， +也会在 kallsyms/objcopy 阶段暴露工具缺失或执行路径问题。 + +### 5. kallsyms padding 极慢 + +`starry-kallsyms.sh` 原先用类似 `dd bs=1` 的方式补齐 `.kallsyms` section。 +在 StarryOS guest 文件系统里，这种逐字节写入会触发大量小写入和元数据更新， +非常慢，容易表现成“编译已经差不多完成但后处理卡住”。 + +### 6. ext4 写入路径元数据同步过重 + +排查过程中确认 StarryOS 的 ext4/rsext4 路径对普通文件写入、append、`set_len` +做了过重的同步。Cargo/rustc 会产生大量小文件、临时文件、rename、truncate， +如果每次普通写入都同步整套文件系统元数据，guest 内构建会被严重拖慢。 + +另外，extent 文件 truncate 扩展时不应该为了逻辑增长提前分配并清零所有块； +Linux 语义下增长出来的新区域应当按 sparse/zero-read 处理。 + +### 7. 自举编译出的 kernel 还需要能按普通 xtask 路径启动 + +自举编译完成只是第一步，还要证明 guest 生成的 kernel 不是只能“编出来”，而是能 +按普通 StarryOS qemu-aarch64 路径启动并进入 shell。 + +这个过程中又暴露出几类 runtime 问题： + +- FD table 初始化时会在 AArch64 kernel stack 上形成巨大临时对象； +- kprobe/kretprobe selftest 存在递归锁和 kernel task fallback 问题； +- `membarrier` 常量使用了“命令编号”而不是 Linux UAPI bitmask，测试期望也随之错误。 + +## 排查方式 + +### 1. 增加 host heartbeat + +`run_selfbuild.sh` 会周期性输出： + +```text +host-heartbeat elapsed= qemu_pid= ... +``` + +这个输出用于确认： + +- 宿主机 runner 仍在运行； +- QEMU 进程仍存在； +- Cargo 最近一条进度是什么； +- 是否命中 timeout、panic、trap、segfault 等 fail pattern。 + +它帮助区分“QEMU 退出了”和“guest 内部卡住了”。 + +### 2. 增加 target heartbeat + +guest runner 增加 `TARGET_HEARTBEAT_SEC`，周期性统计 target 目录： + +```text +===STARRY-MACOS-SELFBUILD-TARGET-HEARTBEAT +dir=/tmp/starryos-selfbuild-target +kib= +files= +changed= +sample= +=== +``` + +最早卡住时，target 目录文件数长期不再变化。例如旧日志里 `254/318` 附近， +heartbeat 的 files 数停住，说明不是单纯 Cargo UI 没刷新，而是构建产物确实没有继续生成。 + +### 3. 降低变量组合，分别测试 SMP/JOBS/source tmpfs + +分别尝试过： + +```text +SMP=8 JOBS=8 +SMP=4 JOBS=4 +SOURCE_TMPFS=0 +SOURCE_TMPFS=1 +RUSTC_THREADS=1/2 +RAYON_NUM_THREADS=1 +``` + +结论是： + +- `SMP/JOBS` 会影响并发，但不能解决 guest 内部串行卡点； +- source/target 放到 `/tmp` 能显著减少 ext4 写入压力； +- `RUSTC_THREADS=2` 是当前本地复现较稳定的设置； +- 单纯加大 `SMP` 或 `JOBS` 不会绕过 FS/runtime 问题。 + +### 4. 单独编译 crate 收敛问题 + +排查时尝试过把完整构建拆成单 crate 或更小依赖组来观察是否复现卡死。 + +如果单独 crate 也卡住，问题更偏向 StarryOS syscall/FS/runtime；如果单独能过， +再回到完整依赖图看是哪个组合触发。这个方式帮助把“源码问题”和“OS 环境问题” +区分开来：同一份源码在 macOS 宿主机能编译，但在 StarryOS guest 卡住，说明 +核心问题还是 StarryOS 作为构建 OS 时暴露出的系统能力问题。 + +### 5. 对齐 qemu-aarch64 动态平台配置 + +最终复现脚本不修改公共 `xtask starry qemu` 入口，而是在 +`apps/starry/macos-selfbuild/run_selfbuild.sh` 内部显式传入本场景需要的 QEMU/HVF +参数、rootfs、内存和 dynamic platform features。这样 macOS self-build 的编译 +配置只存在于这个 app 的脚本和配置文件里，不影响其它 StarryOS QEMU 使用者。 + +### 6. 使用 debugfs/提取脚本验证 rootfs 产物 + +最终 guest 会把产物复制到 rootfs copy 内： + +```text +/opt/starryos-selfbuild-artifacts/starryos-aarch64-unknown-none-softfloat +/opt/starryos-selfbuild-artifacts/starryos-aarch64-unknown-none-softfloat.bin +``` + +先用 `debugfs` 手动提取验证，后续整理成脚本： + +```bash +eval "$(apps/starry/macos-selfbuild/extract_kernel.sh)" +``` + +脚本默认从最新 rootfs copy 中提取 ELF 和 `.bin`，并输出： + +```text +rootfs_copy=... +kernel_elf=... +kernel_bin=... +``` + +##
