STATUS.md/TASKBOARD.md under-reported several subsystems that are in fact
implemented. Corrected against the code and against a clean QEMU boot log
(.build_tmp/qemu_final.log, this branch).
- 页表映射接口 was ⬜ "mmio 通用映射待做". It exists and is in use:
kernel_api.mm_map_mmio / mm_unmap_mmio (PCD|PWT independent window), called
by apic, ehci, xhci and nvme, including BARs above 4G. -> ✅
- NVMe was 🔶 "PCI discovery only, BAR0>4G 待映射". CODE/DKM/nvme/nvme.c is
1641 lines: admin SQ/CQ with phase bit, IDENTIFY, IO queue (qid=1), read/
write/flush, cross-page PRP lists, MSI and MSI-X (vector allocator, IDT pool
0x40-0xDF), block provider registration, NVME-E01..E03 zero-fallback
instrumentation. -> ✅
- virtio_net was 🔶 "PCI/capability 枚举, 无 virtqueue". It has a legacy
split-ring virtqueue (desc/avail/used), vq_setup, 32x2048B RX buffers, TX/RX
rings and a DHCP DISCOVER->OFFER selftest. -> ✅
- ELF64 .drv loading said 14/14. build.ps1 now compiles all 17 drivers listed
in manifest.json (fixed on this branch; nine were never built since 055c521
untracked the .drv binaries). -> 17/17
- FAT32 (DKM side) stays 🔶 but the boundary was wrong. It is read-only
BPB/FAT/dirent parsing plus a root-directory walk, with no filesystem API
layer (no open/read/stat) - not "子目录路径待完善". The large-disk read/write
path lives in the DSK-side FAT32 implementation.
- TASKBOARD 遗留工程债: vector allocator/MSI-X, NVMe high BAR MMIO and
virtio-net virtqueue RX/TX are done. The remaining FAT32 item is reworded to
what is actually missing (the FS API layer).
Evidence for the driver/NVMe/virtio rows is the boot log on this branch:
14x "[<drv>] driver ready", and with no NVMe controller / virtio-net device
attached the drivers correctly log a warning and still reach "driver ready"
(designed fallback, both listed in the CLAUDE.md whitelist).

# Deshab-OS 任务板
|
||
|
||
> 按 [ROADMAP_INSANE.md](./ROADMAP_INSANE.md) 五期编号的可勾选任务表。
|
||
> 状态：✅ 已实现 · 🔶 演示级 · ⬜ 仅设计。唯一状态源见 [STATUS.md](./STATUS.md)。
|
||
|
||
## 🔩 一期：骨架
|
||
|
||
- [x] F1 内核 panic 统一兜底（莲花崩溃屏 + panic_symbol + DRR 归档）
|
||
- [x] F4 boot_ok 分级启动自检（`[boot] selftest=0|1|2`）
|
||
- [x] F5 可跳过 FirstInit（`[dsk] skip_firstinit` + build/configs 模板）
|
||
- [x] F2 统一帧缓冲控制台抽象（fbcon.h：panic 路径已用；统一控制台后端待做）
|
||
- [x] F3 跨平台构建（根 Makefile：make dev/release/realtest；macOS 打包受 mkfs.ext4 限制）
|
||
|
||
## 🗝️ 二期：仪式（UTSM/UTRW）
|
||
|
||
- [x] U1 UTSM 元数据区 / UUID 调谐表
|
||
- [x] U2 UTRW Slow Path 真分支（EPOCH/KEY_MISS 恢复 + MAC_FAILED/POISONED→DRR；selftest PASS）
|
||
- [x] U3 `@sealed` 段可选标记（`UTSM_SEG_F_UNSEALED` 明文直存段 + linker.ld `.sealed` section；selftest PASS）
|
||
- [x] U4 密文页 dump 工具（utrw_debug_dump_page：密文/明文 hex 对照，selftest 演示 PASS）
|
||
- [x] U5 UTSM selftest 全覆盖（RFC 8439 KAT 落地，"间歇 FAIL" 确认为幽灵缺陷；全量稳定 PASS）
|
||
|
||
## 🔌 三期：自由（DKM/用户态）
|
||
|
||
- [x] D5 最小 REPL/shell（shell.elf 25+ 命令）
|
||
- [ ] D1 DKM 热卸载（引用计数 + 资源回收，循环 100 次不崩）
|
||
- [ ] D2 裸机器码加载器
|
||
- [ ] D3 内核 API 按名导出表（kapi()）
|
||
- [x] D4 DKM 彩色日志前缀（驱动名 hash → 8 色 ANSI，init 期着色，BOOTLOG 保持纯文本）
|
||
|
||
## ⏪ 四期：落款（DRR/PCQ）
|
||
|
||
- [x] R1 checkpoint 快照（A/B 双槽 + CRC64 + 原子切换）
|
||
- [x] R2 看门狗（timeout 检出 + 回滚/复位，负向测试 PASS）
|
||
- [x] R3 Emergency Pool（64KB 编译期独立池）
|
||
- [x] R3b `drr_emergency_pool_kb` / `drr_recovery_log_size` FUCK 键接线（运行期钳位到编译期上限）
|
||
- [ ] R4 A/B 回滚收尾（segment/system 级验证，依赖真实加密）
|
||
- [ ] R5 PCQ 多核（per-cpu runqueue 负载均衡；BSP-only 🔶）
|
||
|
||
## 🪷 五期：品牌
|
||
|
||
- [x] E5 疯圣典进 docs/（PHILOSOPHY.md）
|
||
- [ ] E1 启动莲花动画
|
||
- [ ] E2 "假想时光键"彩蛋
|
||
- [ ] E3 提交信息规范（疯洁版）
|
||

|
||
|
||
## 遗留工程债（Phase 存档，非五期编号）
|
||
|
||
- [x] Vector allocator / MSI-X（NVMe 使用 IDT 向量池 0x40–0xDF + MSI-X 表项编程）
|
||
- [x] NVMe 高位 BAR MMIO（BAR0>4G，`mm_map_mmio` 独立窗口映射）
|
||
- [x] virtio-net virtqueue RX/TX（legacy split-ring + DHCP selftest）
|
||
- [ ] FAT32 文件系统 API 层（DKM 侧当前只有 BPB/目录 demo，无 open/read/stat）
|
||
- [ ] DKM 零 warning + 统一 ABI 头
