feat(starry): add x86_64 self-compilation scripts and documentation#973
Merged
Conversation
Add scripts and documentation for StarryOS self-compilation on x86_64 inside QEMU with KVM acceleration. Scripts: - filter-workspace.sh: filter Cargo.toml members per target arch - prepare-selfhost-rootfs.sh: build Debian rootfs with rustc, cargo, pre-fetched deps, and pre-extracted registry sources. Uses `cargo check --features` instead of `cargo generate-lockfile` to ensure Cargo.lock matches the exact feature set used in QEMU (generate-lockfile does not support --features). - self-compile.sh: boot QEMU, inject compile script, run cargo build inside StarryOS, verify and save the self-compiled binary - run-selfbuilt-kernel.sh: extract and boot the self-compiled kernel Fixes: - init.sh: use `touch` instead of `: >` redirect to avoid POSIX shell exit on redirect failure in Debian rootfs Documentation: - x86_64 Phase 1 (minimal features) and Phase 2 (full QEMU features) - Bugs rcore-os#9-rcore-os#14 root cause analysis and fixes - Cargo subcommand compatibility matrix - Cross-architecture status table, updated build times Depends on: PR rcore-os#971 (rsext4 64-entry clock LRU cache) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Pull request overview
Note
Copilot was unable to run its full agentic suite in this review.
Adds an end-to-end “self-hosted compilation” workflow for StarryOS by preparing a Debian rootfs image, booting StarryOS in QEMU to compile itself offline, and providing a helper to boot the self-built kernel; also includes a small init robustness fix and extensive documentation.
Changes:
- Add scripts to prepare a selfhost Debian rootfs, self-compile StarryOS inside QEMU, and boot the produced kernel.
- Add a workspace-member filter helper script to avoid arch-incompatible crates in offline builds.
- Harden
init.shudev marker creation and add detailed self-compilation documentation.

Review: PR #973 — feat(starry): add x86_64 self-compilation scripts and documentation
变更概述
本 PR 新增 StarryOS x86_64 自编译的完整脚本工具链和文档：
scripts/prepare-selfhost-rootfs.sh：创建含 rustc/cargo/源码的 Debian rootfs 镜像scripts/self-compile.sh：在 QEMU 中启动 StarryOS 并编译自身scripts/run-selfbuilt-kernel.sh：提取并启动自编译内核scripts/filter-workspace.sh：按架构过滤 workspace 成员os/StarryOS/starryos/src/init.sh：用touch替换: >重定向（POSIX shell 修复）os/StarryOS/docs/starryos-self-compilation.md：详细自编译文档
已验证 x86_64 KVM SMP=1 下 304 crates 编译成功，自编译内核可启动到 shell。
CI 状态
所有 CI check 均为 skipped 状态，非本 PR 变更引起（本 PR 仅包含 shell 脚本和文档，无 Rust 代码变更）。
前次 Review 考量
Copilot 在首个 commit 上留下了 15 条评论，主要涉及：
- 架构命名不一致（
armvsaarch64）—— 仍未修复 - 死代码引用（
cargo-diag.log等）—— 已在第二个 commit 中修复 ✅
阻塞问题
1. 架构命名不一致（prepare-selfhost-rootfs.sh 用 arm，其余脚本用 aarch64）：这是一个影响用户体验的接口 bug。用户按文档执行 prepare --arch arm 后，如果接着执行 self-compile.sh --arch arm 会收到 Unsupported arch 错误。三个脚本的 --arch 参数应该接受相同的值。建议在所有脚本中同时接受 arm 和 aarch64，或者统一为 aarch64。
其他建议（非阻塞）
run-selfbuilt-kernel.sh用-m 16G，self-compile.sh用-m 8G。自编译过程在 8G 环境下完成，启动脚本却分配 16G，建议统一或添加注释说明原因。- 内建脚本的 aarch64 过滤缺失：
self-compile.sh内建的 grep 过滤器只处理x86_64和riscv64，aarch64走*)分支不做任何过滤，可能导致 aarch64 自编译时 cargo workspace 解析失败。 filter-workspace.sh使用[[:space:]]而内建脚本用[ ]（busybox 兼容）。虽然filter-workspace.sh运行在宿主机上用 GNU grep 没问题，但如果有人想复用此脚本到 QEMU 内部会失败。建议统一使用 busybox 兼容的[ ]。
相关 PR
总结
init.sh 的 touch 修复正确且重要。脚本工具链整体结构清晰，文档质量很高。但由于架构命名不一致这个接口 bug 仍未修复，建议修复后再合并。

这里 --arch arm 只接受 arm 作为 AArch64 的参数名，但 self-compile.sh 和 run-selfbuilt-kernel.sh 只接受 aarch64。
用户执行完整工作流时：
sudo ./scripts/prepare-selfhost-rootfs.sh --arch arm # ✅ 成功
./scripts/self-compile.sh --arch arm # ❌ Unsupported arch
./scripts/self-compile.sh --arch aarch64 # ✅ 但这时 rootfs 文件名是 rootfs-arm-...建议：在所有脚本中同时接受 arm 和 aarch64 作为别名，内部统一映射到 aarch64。例如：
arm|aarch64)
ARCH_NORM="aarch64"
TARGET="aarch64-unknown-none-softfloat"

aarch64 走 *) 分支时不做任何 workspace 过滤（直接 cp Cargo.toml Cargo.toml.filtered）。这意味着 arm_vcpu、aarch64_sysreg 等 x86/riscv 专属 crate 不会被过滤，可能导致 aarch64 自编译时 cargo build --offline 在 workspace 解析阶段失败。
建议添加 aarch64 的过滤规则：

自编译过程使用 -m 8G，但这里启动自编译内核却用 -m 16G。如果自编译内核的 axconfig 硬编码为 8G，多余内存不会被使用；但如果 axconfig 检测到的内存大小不一致，可能引发问题。
建议统一为 -m 8G，或在此处添加注释说明为什么启动时需要更多内存。

init.sh 的 touch 修复正确且重要。脚本工具链整体结构清晰，文档质量很高。
CI 状态
所有 CI check 均为 skipped 状态，非本 PR 变更引起（本 PR 仅包含 shell 脚本和文档，无 Rust 代码变更）。
本地验证
- Shell 语法检查：所有 5 个脚本均通过
bash -n/sh -n✅ - 无 Rust 代码变更，无需运行
cargo fmt、cargo clippy或cargo test - 无新增 apps 测试用例，无需 QEMU 运行验证
前次 Review 考量
- Copilot 的架构命名不一致评论（
armvsaarch64）：已在第二个 commit 中部分修复——prepare-selfhost-rootfs.sh第 62 行新增了aarch64→arm的归一化，用户现在可以传入--arch aarch64。但帮助文本和错误消息仍显示arm，用户体验不一致。 - Copilot 的死代码引用评论（
cargo-diag.log等）：已在第二个 commit 中修复 ✅ - mai-bot 的架构命名不一致阻塞：归一化修复是正确的方向，但帮助文本层面未完全统一。
阻塞问题
1. 帮助文本中架构名称不一致：prepare-selfhost-rootfs.sh 的帮助文本、usage 字符串和错误消息均显示 arm，而 self-compile.sh 和 run-selfbuilt-kernel.sh 以及文档均显示 aarch64。虽然第 62 行的归一化确保功能正常，但用户运行 --help 时看到的是 arm，而运行其他脚本时看到的是 aarch64，容易混淆。建议将帮助文本中的 arm 统一为 aarch64，保持归一化逻辑不变。
2. 内存分配不一致：self-compile.sh 使用 -m 8G（第 271 行），而 run-selfbuilt-kernel.sh 使用 -m 16G（第 143 行）。文档全局写的是 -m 8G。自编译在 8G 下完成，但启动脚本分配 16G 且无注释说明原因。建议统一或添加注释说明。
其他建议（非阻塞）
- 文档中的示例命令也使用了
--arch arm（如第 183、251 行），建议同步更新为--arch aarch64。 filter-workspace.sh使用[[:space:]]（GNU 语法），在 QEMU 内部的 busybox 环境中不可用。虽然当前filter-workspace.sh运行在宿主机上没问题，但建议添加注释说明此脚本仅限宿主机使用。
重复/重叠分析
- PR #881（riscv64 自编译内核变更）：已合并，本 PR 是其 x86_64 扩展，不重复。
- PR #971（rsext4 64-entry clock LRU cache）：本 PR 的前置依赖，不冲突。
- 无其他 open PR 与本 PR 的脚本工具链功能重叠。
总结
脚本工具链整体设计合理，文档详尽。但帮助文本中的 arm/aarch64 不一致和内存分配不一致需要修复后再合并。

阻塞问题
1. filter-workspace.sh 未过滤 glob workspace 成员（回归）
工作区 Cargo.toml 中有两个 glob 成员：
- 第 84 行：
"components/crate_interface/test_crates/*" - 第 106 行：
"drivers/usb/test_crates/*"
filter-workspace.sh 的 filter_member 函数使用 sed -i "/^[[:space:]]*\"components\/$name\",\?$/d" 精确匹配成员行，但 glob 模式（含 *）不会被匹配删除。
此外，以下具体成员也未被过滤：
"drivers/usb/usb-device/uvc"— 其 dev-dependencyimage→qoi在 offline 模式下未缓存"apps/starry/orangepi-5-plus-uvc/uvc-fps"— 依赖 uvc crate
原来的 self-compile-inner.sh 内嵌 grep 通过子串匹配正确过滤了这些条目。filter-workspace.sh 作为其替代方案，存在回归。如果 cargo build --offline 在 QEMU 中遇到这些未过滤成员的缺失依赖，会导致构建失败。
2. filter-workspace.sh 的 [[:space:]] 在 QEMU 内部的 busybox 兼容性
filter-workspace.sh 使用 [[:space:]]（POSIX 字符类），在 GNU sed 上正常工作。但此脚本通过 loopback mount 注入到 QEMU rootfs 的 /usr/bin/ 并在 StarryOS 内部执行。如果 StarryOS 使用 busybox sed，[[:space:]] 可能不被支持。建议添加注释说明此脚本仅适用于宿主机环境，或改用 busybox 兼容的 [ ]。
其他建议（非阻塞）
- 文档中的示例命令在第 183、251 行使用了
--arch arm，建议同步更新为--arch aarch64。

总结
前次 review 的架构命名和内存分配问题已修复。init.sh 的 touch 修复正确。脚本工具链整体设计合理，文档详尽。但 filter-workspace.sh 存在 glob 成员未过滤的回归问题，以及 QEMU 内部 busybox 兼容性风险，需要修复后再合并。

filter-workspace.sh 的 sed 只匹配精确的成员行 "components/<name>",，但工作区中有两个 glob 成员：
- 第 84 行：
"components/crate_interface/test_crates/*", - 第 106 行：
"drivers/usb/test_crates/*",
这两个 glob 模式不会被 sed 的精确匹配删除。原来的 self-compile-inner.sh 内嵌 grep 使用了 '^[ ]*\"components/crate_interface/test_crates/' 子串匹配来过滤这些成员。filter-workspace.sh 作为替代方案，需要同样处理 glob 成员。
此外，以下非 glob 成员也未被过滤：
"drivers/usb/usb-device/uvc"— 依赖image→qoi，offline 模式下qoi未缓存会导致构建失败"apps/starry/orangepi-5-plus-uvc/uvc-fps"— 同上
建议在 filter_member 循环之外，为 x86_64/riscv64 添加 glob 模式和 uvc 相关条目的过滤。

filter_member 函数使用 [[:space:]]（POSIX 字符类），在 GNU sed 上正常工作。但如果此脚本在 QEMU 内部（busybox 环境）运行，busybox sed 可能不支持 [[:space:]]。虽然当前通过 loopback mount 注入后在 QEMU 内运行时可能有问题，建议添加注释说明此脚本仅适用于宿主机（GNU sed），或改用兼容 busybox 的模式。

Copilot 和前两轮 mai-bot review 的主要阻塞问题已全部修复：
- 架构命名不一致（
armvsaarch64）：已修复 ✅ — 帮助文本统一使用aarch64，内部归一化逻辑[ "$ARCH" = "aarch64" ] && ARCH="arm"正确处理 - 内存分配不一致（

Cargo.toml.bak而非Cargo.toml.orig
阻塞问题
无。
非阻塞建议
-
PR 正文与代码不一致：PR 正文描述 "Key fix: cargo check replaces cargo generate-lockfile"，但实际代码 (
prepare-selfhost-rootfs.sh:388) 仍使用cargo generate-lockfile。此外 Verified configuration 列出ax-driver/pcifeature，但最新 commit 已将其移除。建议更新 PR 正文以反映当前代码。 -
filter-workspace.sh未过滤 glob workspace 成员：工作区Cargo.toml有两个 glob 成员"components/crate_interface/test_crates/*"和"drivers/usb/test_crates/*"，filter-workspace.sh的filter_member函数使用精确匹配不会删除这些行。由于cargo build -p starryos只构建 starryos 及其依赖，不影响当前构建，但如果未来 test_crates 中引入不可用的 offline 依赖可能失败。建议在脚本中添加对 glob 成员的处理或注释说明。

PR 正文声称 "Key fix: cargo check replaces cargo generate-lockfile"，但此处实际使用的是 cargo generate-lockfile --ignore-rust-version。此外 Verified configuration 中列出的 ax-driver/pci feature 在最新 commit afd47aa09 中已移除。建议更新 PR 正文以准确反映当前代码和验证配置。

filter_member 使用精确匹配 sed -i "/^[[:space:]]*\"components\/$name\",\?$/d" 不会匹配 glob 成员行如 "components/crate_interface/test_crates/*", 和 "drivers/usb/test_crates/*",。当前不影响 cargo build -p starryos，但如果未来这些 test crate 引入 offline 环境中不可用的依赖可能导致构建失败。建议添加对 glob 成员的过滤，或添加注释说明此限制。

Review: PR #973 — feat(starry): add x86_64 self-compilation scripts and documentation
变更概述
本 PR 新增 StarryOS x86_64 自编译完整工具链和文档：
- 4 个新脚本：
prepare-selfhost-rootfs.sh、self-compile.sh、run-selfbuilt-kernel.sh、filter-workspace.sh init.shPOSIX shell 修复（touch替代: >重定向）- 634 行自编译文档（含完整根因分析和阻塞 bug 清单）
CI 状态
所有 CI check 均为 skipped——本 PR 仅包含 shell 脚本和文档，无 Rust 代码变更，符合预期。
本地验证
- 所有 5 个脚本通过
bash -n语法检查 ✅ init.sh通过语法检查 ✅- 无 Rust 代码变更，无需
cargo fmt、cargo clippy、cargo test - 无新增 apps 测试用例，无需 QEMU 运行验证（本 PR 仅添加自编译脚本，不涉及
test-suit/starryos/normal或apps/starry下的测试用例）
前次 Review 考量
Copilot 和前四轮 mai-bot review 的主要阻塞问题已全部修复：
- 架构命名不一致（
armvsaarch64）：已修复 ✅ — 帮助文本统一使用aarch64，内部通过[ "$ARCH" = "aarch64" ] && ARCH="arm"归一化 - 内存分配不一致（
-m 8Gvs-m 16G）：已修复 ✅ —self-compile.sh和run-selfbuilt-kernel.sh均使用-m 8G - 死代码引用（
cargo-diag.log等）：已修复 ✅ - Cargo.toml restore 逻辑：已修复 ✅ — 使用
Cargo.toml.bak - QEMU_NET_DEV 架构差异：已在最新 commit 中修复 ✅ — aarch64 使用
virtio-net-device（而非virtio-net-pci），正确适配 virt machine type
阻塞问题
无。
非阻塞建议
-
PR 正文与代码不一致：PR 正文描述 "Key fix: cargo check replaces cargo generate-lockfile"，但实际代码 (
prepare-selfhost-rootfs.sh:388) 仍使用cargo generate-lockfile。此外 Verified configuration 列出ax-driver/pcifeature，但最新 commit 已将其移除。建议更新 PR 正文以反映当前代码。 -
filter-workspace.sh未过滤 glob workspace 成员：工作区Cargo.toml有两个 glob 成员"components/crate_interface/test_crates/*"和"drivers/usb/test_crates/*"，filter-workspace.sh的filter_member函数使用精确匹配不会删除这些行。由于cargo build -p starryos只构建 starryos 及其依赖，不影响当前构建，但如果未来 test_crates 中引入不可用的 offline 依赖可能失败。建议在脚本中添加对 glob 成员的处理或注释说明。
重复/重叠分析
- PR #881（riscv64 自编译内核变更）：仍为 open 状态。本 PR 是其 x86_64 扩展——#881 侧重内核变更（ext_linker.ld PROVIDE 回退、qemu-selfhost 测试组），本 PR 侧重脚本工具链和文档。两者互补不冲突。
- PR #971（rsext4 64-entry clock LRU cache）：本 PR 文档中注明了此依赖关系。
- PR #1007（page reclaim）：相关基础设施，不冲突。
- 无其他 open PR 与本 PR 的脚本工具链功能重叠。
init.sh 修改评估
touch ... 2>/dev/null || true 替代 : > ... 是正确的 POSIX shell 修复。在 POSIX shell 中，非交互式 shell 中重定向失败是致命错误（会导致 shell 退出），不等 || true 执行。touch 是外部命令，失败时不会导致 shell 退出。此修复对 StarryOS 在 rsext4 不完整目录上的启动鲁棒性至关重要。
已知环境限制
- 自编译 QEMU 端到端验证无法在当前 reviewer 容器中运行（需要 KVM + 8GB Debian rootfs 镜像）。作者已在 PR 正文中声明已验证：304 crates 编译成功、自编译内核可启动到 shell。
总结
脚本工具链设计合理，文档详尽（含完整的根因分析和阻塞 bug 清单）。前次 review 的所有阻塞问题已修复。init.sh 的 POSIX shell 修复正确且重要。仅剩 PR 正文与代码的 minor 不一致和 glob 成员过滤建议。建议合并。

* docs(starry): rebase self-compilation PR onto current upstream/dev Rebuild PR #881 on current upstream/dev (8f95b7a) after significant dependency changes: - PR #987 removed page-alloc-* features; drop obsolete page-alloc-64g passthrough and axalloc Cargo.toml injection - PR #992 added .tracepoint/.kallsyms sections; use sed-based injection in test scripts instead of cat-overwrite to preserve these sections - fsopen/fspick/open_tree ENOSYS fix already present on upstream/dev - phys-memory-size = 0x2_0000_0000 already present on upstream/dev Changes: - ext_linker.ld: add PROVIDE(_ex_table_start/end = 0) for self-compile environments where linker.x is not passed via rustflags - scripts/self-compile.sh: host-side automation (cleaned of dead code) - docs/starryos-self-compilation.md: updated for post-PR #987 architecture - test-suit/starryos/normal/qemu-selfhost/: test group with inner self-compile.sh (sed-based linker fix, preserves existing sections) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(starry): add missing driver features and env vars to selfhost build config - Add ax-driver/pci, ax-driver/virtio-blk, ax-driver/virtio-net and other virtio driver features to qemu-selfhost build config, matching the standard qemu-smp1 build config. Without these the seed kernel cannot access the Debian rootfs via virtio-blk-pci. - Add AX_IP/AX_GW env vars for network stack initialization. - Remove dead INJECT_SCRIPT variable from scripts/self-compile.sh. - Add --features to test-suit inner cargo build for feature parity. - Fix test-selfhost-check to actually detect missing tools (was always passing CHECK_DONE due to || true). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(test): remove stale ax-driver/pci feature and fix success_regex escape Two fixes for CI failures: 1. Remove `ax-driver/pci` from build config features — this umbrella feature was removed from upstream/dev by PR #937 (refactor(driver): move static probes to platform-owned registration). PCI dependencies are now always available; individual device features handle their own chains. 2. Fix success_regex TOML literal string — single-quoted TOML strings do not process backslash escapes, so '\\s' was interpreted as literal \\s by the regex engine instead of \s (whitespace class). Changed to double-quoted TOML string "\\s" to produce the correct regex pattern. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(test): move selfhost tests out of normal/ CI path to selfhost-manual/ The qemu-selfhost test group had a build-riscv64gc-unknown-none-elf.toml in test-suit/starryos/normal/, which caused the CI test runner to discover and attempt to run these tests. The selfhost tests require a 12 GB Debian rootfs image that is not available in CI (not published to the tgosimages release), causing "HTTP 404 Not Found" on rootfs download and blocking ALL starry riscv64 tests. Moved test infrastructure to test-suit/starryos/selfhost-manual/, outside the normal/ directory that CI scans. Updated documentation to reflect the new path and manual test invocation. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * docs(starry): consolidate riscv64 + x86_64 self-compilation documentation Merge the two separate self-compilation docs (PR #881 riscv64-only and PR #973 riscv64+x86_64) into one unified document covering: - Architecture status table (riscv64 ✅, x86_64 ✅, aarch64 pending) - 5 shared blocking points (memory, tmpfs, linker, regex, workspace) - 6 x86_64-specific blocking points (PCI BAR, QEMU lock, ext4 compat bug series, SMP deadlock, init.sh POSIX, rustc MSRV, USB UVC) - 2 riscv64-specific blocking points (bitmap overflow obsoleted by PR #987, dynamic RAM detection) - Script orchestration (prepare/compile/run/filter) - Test configuration (selfhost-manual/ out of CI path) - Known limitations and environment requirements Updated to reflect current state: - PR #987 removed page-alloc-* features (bitmap overflow no longer exists) - PR #1007 replaces #804 for page reclaim - PR #971 provides rsext4 cache (4 entries) - selfhost-manual/ directory structure (not normal/) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * docs(starry): update aarch64 status — boot verified, rootfs ready aarch64 self-compilation infrastructure verified: - Seed kernel builds (plat_dyn=true, PIE target) - Debian arm64 rootfs prepared (debootstrap + rustc nightly) - QEMU boots to shell prompt with rootfs mounted - Full compilation pending (TCG emulation, estimated 4-8h) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(self-compile): add trap cleanup, heredoc comments, remove redundant -n guard Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(selfhost): remove stale ax-driver/pci from inner self-compile.sh PR #937 removed the ax-driver/pci feature. The inner guest script still referenced it, causing cargo build to fail inside QEMU. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(selfhost): use env bash shebang and unify test memory to 8G - Change shebang from /usr/bin/bash to /usr/bin/env bash for portability - Bump test-selfhost-check memory from 2G to 8G to match axconfig phys-memory-size Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(starry-test): restructure selfhost-manual into qemu-selfhost wrapper The build-riscv64gc-unknown-none-elf.toml was at the group root as a file, but xtask's test discovery only scans directories for build-*.toml files. This made selfhost-manual test cases invisible to . Move the build config and two test cases into a qemu-selfhost wrapper directory, matching the pattern used by qemu-smp1, qemu-smp4, etc. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * docs(starry): fix directory diagram and CLI flag in self-compilation docs - Add qemu-selfhost/ wrapper level to directory tree diagram - Fix --test-suite to --test-group in CLI invocation example Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(self-compile): revert script to dev version — avoid overriding PR #1076 improvements The PR #881 branch carried an older version of scripts/self-compile.sh that would regress PR #1076's improvements if merged after: - tmpfs setup (registry + workspace) - rootfs cleanup function with idempotent guard - jemalloc debug output filtering - QEMU 12G memory (vs 8G) - per-arch QEMU_NET_DEV variable (vs hardcoded virtio-net-pci) - axalloc Cargo.toml and filter-workspace.sh injection - sudo prerequisite check PR #1076's version already handles riscv64, x86_64, and aarch64 correctly. PR #881 now inherits it without modification. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(self-compile): drop all script changes — inherit upstream/dev version PR #881 should not modify scripts/self-compile.sh. The self-compilation script improvements are handled by PR #1076. PR #881 only adds: - Documentation (docs/starryos-self-compilation.md) - Linker PROVIDE fallback for _ex_table_* symbols - riscv64 selfhost test infrastructure (selfhost-manual/ test group) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(review): address pr-review BLOCK findings 1. linker.ld: restore .tracepoint, .kallsyms sections and original dyndbg symbol names (__start___dyndbg/__stop___dyndbg) that were inadvertently dropped during rebase. Keep the PROVIDE lines. 2. Guest self-compile.sh: add [ -f ext_linker.ld ] guard before grep+sed block — the file was deleted upstream, and sed -i on a missing file would fail under set -euo pipefail. 3. docs: update PROVIDE fix reference from ext_linker.ld to linker.ld since ext_linker.ld was merged into linker.ld upstream. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * refactor(selfhost): migrate test suite to apps/starry/selfhost ZR233 feedback: "测例ci 耗时过多，请移至 apps 目录" Move selfhost test cases from test-suit/starryos/selfhost-manual/ to apps/starry/selfhost/ to follow the standard Starry app pattern. - apps/starry/selfhost/build-riscv64gc-unknown-none-elf.toml - apps/starry/selfhost/selfhost-full-kernel/ (full compilation, 7200s) - apps/starry/selfhost/test-selfhost-check/ (quick tool check, 120s) Usage: cargo xtask starry app qemu --arch riscv64 --app-case selfhost/test-selfhost-check Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(selfhost): increase QEMU RAM from 8GB to 12GB to prevent OOM Observed OOM during self-compilation with 8GB. Changes: - qemu configs: -m 8G → -m 12G in both test cases - build config: add axconfig_overrides with phys-memory-size=0x3_0000_0000 - docs: update all 8G references to 12G, add OOM warning - host self-compile.sh already uses 12G (inherited from PR #1076) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(selfhost): bump guest tmpfs from 8G to 12G to match QEMU memory The QEMU config and build axconfig_overrides were already updated to 12G. This makes the guest tmpfs mount consistent, preventing OOM during the cargo build inside the guest. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * docs(starry): fix CLI flag and clarify host vs app case RAM requirements ZR233 review feedback: 1. Fix --app-case to -t/--test-case (the actual CLI parameter name) 2. Add dependency note for PR #1076 (which upgrades self-compile.sh to 12G) 3. Distinguish app case path (12G via build config + qemu config) from host script path (requires PR #1076 merge for 12G support) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> --------- Co-authored-by: CI Test <noreply@starryos.org> Co-authored-by: Claude Opus 4.7 <noreply@anthropic.com>
