+ +需要确认 UTSM 是否使用 GS(关系到 PE64 的 TLS 支持方案)。 + +现在开始构建 Rust 应用骨架。先确认依赖缓存完整性。 + +依赖全部可用(egui 0.31.1 无 atomic_refcell 依赖,缓存完整)。现在创建 Rust crate。 + +Now let me look at the PE loader, how the shell invokes PE files, and the UTSM build setup. + +Now I have a full picture of the architecture. Let me set up the task plan and check the build environment. + +The original app uses egui 0.27 and the local registry cache has egui 0.27.2 (no 0.31.1). I'll switch to the cached version for an offline build. Let me check egui 0.27.2's dependency tree. + +All deps are cached. Now let me check existing timing/input patterns in the codebase (PIT/TSC calibration, PS/2 polling) that the shim can reuse. + +API details confirmed. Let me check the QEMU framebuffer setup, then write the Rust app. + +Now let me verify a couple more egui 0.27 API details (ViewportIdMap accessors, RawInput::default focused flag). + +All API details confirmed. Now writing the code — first update Cargo.toml to the cached egui 0.27.2: + +Now update raster.rs to avoid `std::collections::HashMap` (RandomState would pull in an OS-RNG import): + +Now write the main application file: + +Let me verify the egui 0.27 `Key` enum layout before relying on discriminant arithmetic: + +Now build the PE: + +Build failed inside ttf-parser with bizarre prelude errors. Let me see the first errors: + +Let me isolate this with a minimal reproduction: + +A bare crate fails too — the sysroot's `libcore` seems broken (metadata stub). Let me try repairing the target std: + +The sysroot is corrupted (libcore's .rmeta missing, .rlib stub-sized). Force reinstall the component: + +The download is stalled at 0 bytes — likely network issues reaching static.rust-lang.org. Let me switch to a domestic mirror: + +Sysroot repaired. Rebuild the PE: + +Let me run the build to see the current error state. + +Let me see the full error output to get the complete list of undefined symbols. + +I have the complete list of 19 undefined symbols. The fix: implement them inside the PE binary itself (a small `rt.rs` runtime module — these are link-time symbols, not DLL imports, so the UTSM shim can't provide them). Let me review the current sources first. + +Now I have the full picture. I'll create a `rt.rs` module inside the PE crate providing all 19 missing link-time symbols (these can't come from the UTSM shim — they're not DLL imports): CRT memory intrinsics, f32 math (musl-derived), MSVC runtime symbols (`__chkstk`, `_fltused`, `_tls_index`, `_tls_used`, `__CxxFrameHandler3`), plus a defensive fake-TEB install for std TLS access. + +Now wire `rt` into main.rs — install fake TLS at entry and restore it before every ExitProcess. + +Only one new missing symbol: `trunc` (f64, from my `rem_pio2_medium`). Adding it to rt.rs: + +Build succeeded. Now dump the PE headers and import table to enumerate exactly what the UTSM shim must cover. + +PE32+ confirmed (Magic 0x20B, AMD64). Now the import table: + +Complete import table captured. Now let me study the existing UTSM PE shim/loader to plan the extension. + +I now understand the shim architecture. Next I need: arena capacity, framebuffer access path, kernel_api surface, and where SSE/CR state is set up in UTSM boot. + +Arena is a fixed 16MB BSS array — too small for a GUI PE (image 2.2MB + stack + DIB 1.9MB + egui atlas/heap). I'll need to bump it. Now let me check the kernel_api surface for framebuffer access and SSE setup points in boot code. + +Now let me check the build pipeline and how cmd.elf locates PE files on FAT32. + +我先了解当前状态:确认 PE64 构建产物、查看现有 shim 覆盖情况,然后继续推进剩余任务。 + +PE64 已构建。现在 dump 其导入表,并读取现有 shim 实现: + +导入表已获取。现在读取现有 shim 实现,对比覆盖差距: + +现有 shim 仅覆盖 kernel32/msvcrt 基础子集。现在读取 Rust 端的 Win32 使用方式和 pe_service.c 执行路径,确定 shim 语义: + +现在读取 Rust 端 win32 绑定和 UTSM 中帧缓冲/键盘的可用接口: + +查看 UTSM 内核中帧缓冲信息的存储方式,以及键盘输入的可用接口: + +查看 cmd.elf 的键盘输入方式(PE 从 cmd 启动,shim 的消息泵需与之兼容)以及 kernel_api 的导出情况: + +查看 UTSM 主入口,确定 SSE 启用的最佳位置: + +现在读取其余关键文件:raster.rs 像素格式、pe_loader.c IAT 填充、arena 分配对齐、run_qemu.bat、cmd 的 pe 命令: + +现在查看 pe_loader.c 的 PE32+ 加载细节(BSS 处理)、run_qemu.bat 启动方式、以及 deaicup.exe 大小: + +deaicup.exe 2.2MB。现在确认 DSK 启动流程(firstInit/login/desktop → 如何启动 cmd.elf),为 QEMU 自动化设计按键脚本: + +需要确定桌面上 CMD 图标的坐标,用于 QEMU 鼠标自动化。读取 shortcut 布局和点击处理代码: + +桌面启动 cmd 需要鼠标双击,自动化脆弱。我选择两个最小且通用的开发特性来实现稳定自动化:DSK 增加 FUCK `cmd_mode` 直启 cmd.elf,cmd.elf 支持 AUTOEXEC.BAT。先看 DSK 的 FUCK 解析方式: + +设计已定。查看 build.ps1 如何调用 mkfat32.ps1 及各组件构建顺序: + +开始实现。先检查 DSK 给被加载 ELF(cmd.elf)准备的栈大小,评估 Rust/egui 递归是否够用: + +检查 fat32_io.h 的文件读取缓冲能否容纳 2.2MB 的 PE: + +缓冲限制明确:需要 cmd 侧大 PE 缓冲 + 自定义读取。现在开始实现。先标记 import 表任务完成,进行 shim 扩展: + +现在编写 pe_shim.c 扩展。第一处:文件头注释与 includes: + +第二处:修复 WriteFile 的 u32 写入越界 bug,GetLastError 改为真实全局: + +添加前向声明(heap 函数在使用前需要声明): + +将 msvcrt 内存函数路由到新堆: + +现在插入核心新实现(堆、计时、kernel32 增量、user32、gdi32 等),位于未实现 stub 之前: + +Let me check the current state of the key files to understand where the work stands. + +The shim functions are implemented but the shim table is missing the new user32/gdi32/kernel32 entries. Let me check the full list of implemented shim functions and what the PE app actually imports. + +Now let me check what main.rs actually calls, to see the full set of needed functions: + +Let me view the middle sections of pe_shim.c to see the timing and sync implementations: + +Now add GetMessageW after PeekMessageW, and gdi32 stubs: + +Now add GetSystemInfo to the kernel32 section (after Sleep): + +Now register all new functions in the shim table: + +Shim table complete. Let me verify the top of pe_shim.c for the framebuffer request declaration: + +deaicup.exe is 2.2MB. Let me check how cmd.elf executes PE files and see the shell/DSK autoexec flow: + +Now I understand the DSK flow. Let me check the SYSTEM config files: + +DSK's ELF loader has a 2MB static image buffer. Let me check UTSM's DSK loader limit too, since both will need bumps: + +UTSM uses dynamic arena allocation. Let me check the arena implementation and its size limits: + +The arena is a fixed 16MB static array — too small for DSK(10.5MB) + shim heap(8MB) + PE image(2.5MB) + DIB(1.9MB) ≈ 23MB. Let me check config.h: + +Now I'll make all the cmd/DSK/config changes. First, bump the arena: + +Now update cmd/main.c: 4MB buffer + AUTOEXEC.BAT support: + +Now add AUTOEXEC.BAT support. Insert the autoexec runner after `execute_command`: + +Now hook run_autoexec into dsk_entry after the banner: + +Now update DSK: bump ELF image buffer and add default_shell handling: + +Now update FUCK config, firstInit.txt, create AUTOEXEC.BAT, and update mkfat32.ps1: + +Now update mkfat32.ps1 to include deaicup.exe and AUTOEXEC.BAT in the SATA image: + +Task 2 done. Now task 3 — enable SSE in UTSM for PE64 native execution. Let me find the PE64 execution path: + +Now add SSE enabling in the PE32+ native execution path: + +Now let me check the PE loader's import resolution to make sure unresolved imports only warn: + +Now update the PE32+ execution branch to use the dedicated stack: + +pe_service.c already includes arena.h. Task 3 complete. Now let's build everything: + +The header comment contains `mem*/str*/` — the `*/` sequences prematurely close the block comment, turning subsequent comment lines into "code". Let me fix the comment and check types.h: + +types.h is fine — the limine.h errors were cascade. Now let me hunt down remaining fullwidth punctuation in pe_shim.c comments (they trigger -Wunicode-homoglyph warnings; the requirement is zero warnings): + +These are all in comments. Let me batch-replace fullwidth punctuation with ASCII equivalents: + +Shell variable expansion ate the script. Let me write a temp PS1 file instead: + +Now fix the fullwidth chars in my own additions to cmd/main.c and dsk/main.c: + +UTSM 构建通过,DSK 的 main.c 缺少 `offsetof` 声明(需 `stddef.h`)。查看并修复。 + +代码库整体不使用 libc 头文件,按既有风格在两处本地定义 `offsetof`: + +`deaicup.exe` 存在且 mkfat32.ps1 中有条目,但打包日志中没有 DEAICUP——可能 build.ps1 重新生成了 mkfat32.ps1 覆盖了修改。检查: + +奇怪:DEAICUP 既没有 "added" 也没有 "SKIP" 行。直接测试路径与文件状态: + +文件存在但脚本输出完全没有 DEAICUP 行。可能是脚本编码问题导致解析异常。直接探测: + +文件内容完全正确。完整运行一次看全部输出: + +QEMU/OVMF 就绪。后台启动 QEMU(TCG、无显示、串口输出到文件、HMP 监控端口用于 screendump): + +串口日志 2.8MB,系统活跃。检查关键标记: + +警告来自 `INSTR_STAT_DECL` 宏展开出的 `_last_ts` 变量。查宏定义: + +构建零警告通过,deaicup.exe 已入镜像。重启 QEMU 验证: + +本轮工作已完成到可人工验证的状态,汇报如下。 + +## 本轮完成的工作 + +### 1. 构建修复(3 个连锁 bug) + +**bug A — DSK/shell 编译失败**:`dsk/main.c`、`shell/main.c` 的 `_Static_assert` 用了 `offsetof` 但 freestanding 环境无 `stddef.h`。修复:两处本地定义 `#define offsetof(type, member) __builtin_offsetof(type, member)`。 + +**bug B — deaicup.exe 静默未入镜像**(隐蔽):`.build_tmp/mkfat32.ps1` 中 DEAICUP 条目上一行的中文注释(`# PE64 GUI 程序 + CMD 自动启动批处理`)以无 BOM UTF-8 保存,PowerShell 5.1 按 GBK 解码时中文字节序列吞掉了行尾换行,使 DEAICUP 整行被并入注释——数组里根本没有这一项,所以既无 `added` 也无 `SKIP`。修复:该注释改为纯英文,文件已无非 ASCII 字节,重跑后 `added ... deaicup.exe (2206208 bytes)`。 + +**bug C — arena OOM 重启循环**(QEMU 实测发现):端到端链路实际已跑通——串口日志显示 `AUTOEXEC.BAT → deaicup → [PE] PE32+ → SSE enabled → mainCRTStartup`,但随后 `[shim] heap region alloc failed` 并整机重启。根因:`CODE/UTSM/MAKEFILE` 无头文件依赖追踪(`%.o: %.c`),`config.h` 从 16MB→64MB 后 `arena.o` 从未重编,utsm.elf 内仍是 16MB 静态 arena(PE 镜像 2.2MB + 独立栈 1MB + DSK/cmd 占用后不足以分配 shim 8MB 堆)。修复: +- MAKEFILE 加 `-MMD -MP` + `-include $(DEPS)`,clean 规则同步清理 `.d` +- 全量 clean 重建,64MB arena 真正生效 + +### 2. 零警告达标 + +clean 重建暴露出插桩系统的既有警告(`idt.c`/`vmexit.c` 共 11 个 `INSTR_STAT_DECL` 展开但未被 SUMMARY 使用的 `_last_ts`,`vmx.c` 未用的 `vmx_write_msr`)。修复:`instr.h` 宏内 `_last_ts` 加 `__attribute__((unused))`(一处修 11 个,保留插桩设计),`vmx_write_msr` 加 `__attribute__((unused))`。 + +**最终构建:零警告、零错误,`ISO/deshab.img` + SATA 镜像(含 deaicup.exe)均已生成。** + +## 修改文件清单 + +- `CODE/dsk/main.c`、`CODE/shell/main.c` — offsetof 本地定义 +- `CODE/UTSM/MAKEFILE` — 头文件依赖追踪 +- `CODE/UTSM/include/utsm/instr.h` — `_last_ts` unused 属性 +- `CODE/UTSM/vmm/vmx.c` — unused 属性 +- `.build_tmp/mkfat32.ps1` — 中文注释改英文(GBK 吞换行修复) + +## 待 QEMU 人工验证(上次日志已确认到 mainCRTStartup) + +请运行 `ISO\run_qemu.bat`,串口应依次出现: + +1. `[cmd] running AUTOEXEC.BAT` → `[cmd] cmdline: deaicup` +2. `[PE] running PE32+ natively` → `SSE/SSE2 enabled` +3. `[deaicup] mainCRTStartup` +4. **不再出现** `[UTSM] arena out of memory` / `heap region alloc failed` +5. 预期新增:`[shim] CreateDIBSection ok` → `[shim] BitBlt first frame on screen`,屏幕显示 egui 界面,Esc 关闭退出 + +已知遗留:shim 消息泵满 64 条丢弃;鼠标输入尚未接入(仅键盘轮询);WM_CLOSE 目前只有 Esc 合成一条路径。 + +端到端链路已推到 `mainCRTStartup`,最后一个 arena OOM 已修复但未实测。我现在跑 QEMU 验证最终渲染。 + +我来开始这个调试任务。首先定位 "Unimplemented handler" 日志的来源,理解 shim 机制。 + +CODE/UTSM 中没有直接匹配,搜索整个项目: + +直接读取 pe_shim.c 查看 shim 机制实现: + +pe_loader.c 中 `PE_SHIM_UNIMPL = 0x1FFFF`,但 "Unimplemented handler" 字符串不在 pe/ 目录。全项目搜索这条日志的来源: + +源码中不存在该字符串,它可能来自**旧构建的二进制**或字符串在运行时被构造。直接在已部署的 utsm.elf 二进制和整个 SYSTEM 目录中搜索: + +找到 PE 产物。现在搜索哪个二进制包含 "Unimplemented handler" 字符串(ripgrep 跳过二进制,所以用 Select-String),同时确认 deaicup.exe 大小: + +Web 搜索无果。换思路:先看项目结构找到 cmd.elf 源码和 build.ps1 对 deaicup.exe 的处理,然后用 llvm-objdump dump import 表: + +LS 输出被 Rust target 目录淹没。换个方式看 CODE 顶层和 dsk 源码: + +在解码器文件中。获取 x86_decode.c: + +看 whpx_handle_mmio 如何调用模拟器: + +继续之前的调试任务。让我先确认当前状态:检查 deaicup.exe 是否已就位,并 dump 其导入表与 shim 表比对。 + +deaicup.exe 已就位,且之前已有 import dump 和 smoke 日志。先查看这些已有成果: + +反汇编正常。继续读 CreateDIBSection 之后的部分: + +继续推进调试任务。先确认当前现场状态:检查 deaicup.exe 是否就位、已有的 import dump 结果、以及 pe_shim.c 当前的 shim 表内容。 + +deaicup.exe 已就位。现在 dump 其导入表,并读取 pe_shim.c 的 shim 表做比对。 + +导入表与 shim 表比对完成。缺失项已经清晰,共 **4 个**,且分两类: + +**缺失函数清单:** + +| #

Let me verify the current state — syntax-check all PowerShell scripts and check which docs still need the automation section. + +QemuTest.ps1 is complete (45500+ monitor ports, -snapshot, HTTP server helpers). Now let me review the 4 new scripts: + +Both look complete. Let me check the remaining two scripts: + +Now let me check the README and the existing scripts to write accurate doc sections: + +Now I have all context. Adding "自动化脚本" sections to the 7 docs: + +All 7 docs updated. Now updating the README: + +Docs complete. Now verifying prerequisites before the full test run: + +All prerequisites present. Starting the full suite run (long-running, will poll): + +The parse check passed, so it's a runtime error. Let me run boot-regression.ps1 directly to see the full error: + +The suite is stopped and no QEMU remains. Now fixing the launcher to redirect QEMU's temp overlay dir to an ASCII path: + +Smoke-testing the fix with the fastest scenario (B2) before the full run: + +Fix verified — B2 PASS in 53.9s. Launching the full suite: + +All 5 boot-regression scenarios progressing. Continuing to poll: + +The suite continues. While it runs, investigating the cmdline pattern mismatch (read-only): + +Found it: `cmd_pe` calls `exec_pe(args, args)` — so the current cmd echoes only the filename (`[cmd] cmdline: HELLO64.EXE`), not `pe HELLO64.EXE`. Test patterns need updating. Let me check git state for recent system changes: + +Re-adding BOM and re-validating under PS 5.1: + +All scripts valid. Checking suite progress: + +B5's only miss is the e1000 not-found anchor. Let me check the actual driver messages and the userapps session log: + +Key insight: `id` arrived as `d`, `ping` as `ng` — first keystrokes are being dropped between commands. Let me read the script's interactive phase: + +Now checking the e1000 not-found message and the pe_service SSE enable scope: + +Checking the actual B5 launch command in the generated .bat: + +修复已应用。先单独验证 B5 场景,再跑全量套件。 + +全量套件已启动。等待并轮询进度。 + +The 021449 run shows the guest reached shell and fileman booted, but `id`/`ping`/`editor`/`browser` anchors never appeared. Let me check whether these tools/commands actually exist and what they output to serial. + +The first character of `id` was systematically lost (`未知命令: d` ×3). Let me see what happened with `ping`/`editor` and check the shell's keyboard polling loop. + +Found something important — shell line 3400 treats scancode 0x17 (the `i` key) as "Ctrl+W erase line" without checking a Ctrl modifier. Let me check `scan_to_ascii` and the `run` command loader. + +The editor fails `sh_load_elf` ("无效格式或过大") 3 times, and fileman hangs after boot. Let me root-cause both — check `sh_load_elf` limits and fileman's mouse polling. + +Found the third bug: `da_mouse_poll` (desktop_app.h:287-291) reads port 0x60 even for keyboard bytes and discards them — eating all keyboard input in fileman/editor/browser. Let me check how desktop's own mouse poll handles this, and browser's boot flow. + +desktop's own poll checks AUX bit BEFORE reading — desktop_app.h does it wrong. Three system bugs confirmed. Now let me check the PE sample build flow for the pe-compat/x86emu32 failures (image predates the gen_pe.py IAT fix). + +SYSTEM/bin still holds the old binaries. Let me deploy via .NET file IO instead. + +New PE binaries deployed. Now regenerate the SATA image so the guest sees them. + +SATA image regenerated with fixed PE binaries. Let me start pe-compat re-run in the background while I restructure userapps-matrix.ps1. + +cmd only runs PE files, so ping can't be automated via cmd either. Now let me rewrite userapps-matrix.ps1 to work around the three confirmed system bugs: + +Now let me check the pe-compat background run progress. + +The guest triple-faults right after jumping to the PE32+ entry. Let me examine the generated PE32+ code in gen_pe.py to verify code/IAT consistency after the fix. + +I suspect a code-generation bug at line 147 (call disp32 packed at offset 10 instead of 9, clobbering the next instruction). Let me verify by dumping the actual generated binary. + +Confirmed: call#1's disp32 was packed at offset 10 instead of 9, producing `call [rip+0x1F300]` (should be 0x1F3) and clobbering `xor ecx,ecx`. Let me check the PE32 builder for the same class of bug: + +build_cmd_exe has the same offset-10 bug (line 514). Let me also check the PE32+ DataDirectory offset — PE32+ optional header data directories start at 112, not 96. + +Only the two call-disp offsets are wrong (data dirs are correct). Fixing both: + +Bug registry updated. Let me check pe-compat progress: + +Same failure.

[isr_halt_stub](file:///d:/Code/Deshab/CODE/UTSM/arch/x86_64/idt.c#L453-L455)**——即 `idt_halt_all()` 已经把所有 IDT 条目替换成了**无日志的安全停机 stub**。这正是上次修复 IDT CS 时埋下的"handler 存活性"问题:**PE 运行期间 IDT 已被整体替换,任何异常/IRQ

主计数器(QEMU 100MHz)是独立时基,一次实验即可分辨"TSC 校准测半(窗口实为 1000ms)"还是"PIT mode3 在 IOAPIC edge 下双触发(实为 200Hz)"。 +3. **IRQ11 强制 level/active-low**:PCI INTx 规范即 level/low,QEMU 无 ISO 覆盖时 flags=0 会被 redir_compose 编成 ISA edge/high,对电平型设备有丢中断风险(assert 期间再来事件无新边沿)。这是 Linux/Windows 在 QEMU 上跑的标准配置。 +4. **spurious 0xFF 防御**:LAPIC spurious 不置 ISR 位,钩子若无条件 EOI,在嵌套场景会误清真正在服的中断位——UTSM 侧加一行特判,零成本消除隐患。 + +先更新文件头注释与 tick
