# Native Task 与实时 HAL 同步实现步骤
|
||
|
||
生成时间:2026-06-21 CST
|
||
|
||
## 1. 目标和边界
|
||
|
||
本文用于指导后续把当前保留的两个 blocker 推进到可验证完成状态:
|
||
|
||
```text
|
||
nativeTaskReady=false
|
||
nativeHalSyncReady=false
|
||
```
|
||
|
||
这里的“完成”不是把浏览器变成真实机床控制器,也不是接入真实硬件 IO;目标是建立一个 LinuxCNC 源码拥有语义的 task/HAL 同步 runtime 边界,使 Web 仿真能按 LinuxCNC task、motion、HAL 的顺序运行程序、执行 MDI/JOG、同步 HAL pin,并把状态反馈到 gmoccapy Web UI。
|
||
|
||
完成后的目标状态:
|
||
|
||
```text
|
||
nativeTaskReady=true
|
||
nativeHalSyncReady=true
|
||
plannerRuntimeReady=true
|
||
fullLinuxCncProgramExecutionReady=true for simulated machine-file runtime
|
||
hardwareDrive=false
|
||
promotionAllowed=true for Web simulation boundary only
|
||
```
|
||
|
||
仍不属于本文范围:
|
||
|
||
- 真实硬件 IO、Mesa/并口/伺服驱动;
|
||
- Linux 内核实时线程等同物;
|
||
- 任意外部 user-M 进程;
|
||
- Python GUI、GTK、Tk、QtVCP runtime;
|
||
- 未经过 LinuxCNC 源码边界验证的 JavaScript CNC 语义。
|
||
|
||
## 2. LinuxCNC 源程序参考清单
|
||
|
||
后续实现必须以这些源文件为主参考,不能用 Web 侧自定义状态机替代 CNC 语义:
|
||
|
||
```text
|
||
linuxcnc/src/emc/task/task.hh
|
||
linuxcnc/src/emc/task/emctask.cc
|
||
linuxcnc/src/emc/task/emctaskmain.cc
|
||
linuxcnc/src/emc/task/taskintf.cc
|
||
linuxcnc/src/emc/task/emccanon.cc
|
||
linuxcnc/src/emc/nml_intf/emc.hh
|
||
linuxcnc/src/emc/motion/usrmotintf.h
|
||
linuxcnc/src/emc/motion/motion.h
|
||
linuxcnc/src/emc/motion/motion.c
|
||
linuxcnc/src/emc/motion/command.c
|
||
linuxcnc/src/emc/motion/control.c
|
||
linuxcnc/src/emc/motion/mot_priv.h
|
||
linuxcnc/src/emc/tp/tp.c
|
||
linuxcnc/src/emc/tp/tc.c
|
||
linuxcnc/src/emc/tp/tcq.c
|
||
linuxcnc/src/hal/hal_lib.c
|
||
linuxcnc/src/hal/hal_priv.h
|
||
linuxcnc/src/hal/components/threads.c
|
||
```
|
||
|
||
当前 `wasm-port/vendor/linuxcnc` 已包含 interpreter、kinematics、TP 所需的一部分源码,但 task 和 HAL 目录是裁剪状态。实施前必须先把上述 task、motion、HAL、NML 相关源文件纳入 vendored source manifest,或者建立只读引用校验,确保构建用的源码和根目录 `linuxcnc/` 中的参考源码一致。
|
||
|
||
## 3. 推荐架构
|
||
|
||
推荐实现为单进程确定性 runtime:
|
||
|
||
```text
|
||
Web UI
|
||
-> linuxcnc-task-hal-worker-client.js
|
||
-> Web Worker
|
||
-> linuxcnc_task_hal.wasm
|
||
-> LinuxCNC task loop
|
||
-> LinuxCNC canonical queue
|
||
-> LinuxCNC motion command queue
|
||
-> deterministic HAL scheduler
|
||
-> LinuxCNC motion controller servo cycles
|
||
-> status snapshot
|
||
-> Web store / Three.js / DRO / G-code panel
|
||
```
|
||
|
||
这个结构不启动 LinuxCNC native 进程、不使用 OS NML IPC、不启动真实 HAL realtime thread。它把 LinuxCNC 的 task/motion/HAL 关键状态机编译到 WASM,并用显式 `step(period_ns)` API 驱动周期。这样浏览器中每一帧都是可复现的,Node 和 browser smoke 可以对同一 G-code 得到一致的 HAL/status 序列。
|
||
|
||
host-native LinuxCNC 只作为对照探针:
|
||
|
||
```text
|
||
native LinuxCNC/halrun probe
|
||
-> 记录 task status、HAL pin、motion status 序列
|
||
WASM task/HAL runtime
|
||
-> 记录同类序列
|
||
对比 artifact
|
||
-> 允许提升 nativeTaskReady/nativeHalSyncReady
|
||
```
|
||
|
||
## 4. textbak 接续文件可复用结论
|
||
|
||
已分析 `textbak` 中和 native task / HAL 相关的接续文件,结论是:当前仓库已有大量 Web 仿真级 virtual HAL、motion matrix、native opt-in probe 和 promotion lock 资产,后续实现 native task/HAL 边界时必须复用这些成果,但不能把它们直接当成 native task/HAL runtime 已完成。
|
||
|
||
### 4.1 可直接复用的工作
|
||
|
||
`textbak/text17.txt` 记录了完整 virtual HAL 闭环,当前对应代码主要在:
|
||
|
||
```text
|
||
wasm-port/runtime/sdk/src/linuxcnc-hal.js
|
||
wasm-port/runtime/opfs/snapshot-store.js
|
||
wasm-port/runtime/ui/simulation/simulation-app.js
|
||
wasm-port/tests/host/verify_project_release_readiness_artifact.mjs
|
||
```
|
||
|
||
可复用内容:
|
||
|
||
- HAL pin family registry:`axisui`、`halui`、`iocontrol`、`motion`、`axis`、`joint`、`spindle`、`coolant`、`tool`;
|
||
- HAL pin/signal/param/net store 结构;
|
||
- `executeVirtualHalcmd()` / `executeVirtualHalCommand()` 的 halcmd fixture 语义;
|
||
- `stepVirtualHalMotion()` / `stepVirtualHalMotionController()` 的 deterministic servo-period stepping 测试模式;
|
||
- `createVirtualHalMotionControllerMatrixReport()` 的 motion matrix 验证项;
|
||
- OPFS snapshot 中的 `createVirtualHalSessionPayload()`、`restoreVirtualHalStateFromSessionSnapshot()`;
|
||
- source compliance、sim-config source coverage、release diagnostics artifact 结构。
|
||
|
||
这些内容应作为阶段 2、阶段 3、阶段 7 的输入,避免重新设计 HAL registry、snapshot、diagnostics 和 motion matrix。
|
||
|
||
### 4.2 只能作为 evidence,不能直接提升的工作
|
||
|
||
`textbak/text17.txt` 和 `textbak/text19.txt` 明确:virtual HAL 在 Web 仿真范围内可以替代 host `halcmd`、host realtime HAL process 和 host motion process,但不能声称提供 Linux kernel hard-realtime ABI、外部硬件驱动 ABI 或 native HAL module ABI。
|
||
|
||
因此:
|
||
|
||
```text
|
||
virtualHalReady=true
|
||
motionControllerMatrix.complete=true
|
||
sourceCompliance.complete=true
|
||
```
|
||
|
||
只能作为 `nativeHalSyncReady` 的前置 evidence,不能直接使:
|
||
|
||
```text
|
||
nativeTaskReady=true
|
||
nativeHalSyncReady=true
|
||
fullLinuxCncProgramExecutionReady=true
|
||
```
|
||
|
||
真正提升仍必须由 LinuxCNC task/motion/HAL WASM runtime 或 host-native 对照探针完成。
|
||
|
||
### 4.3 native opt-in probe 模式
|
||
|
||
`textbak/text21.txt`、`textbak/text24.txt`、`textbak/text28.txt`、`textbak/text35.txt` 和 `wasm-port/docs/full-process-boundary-design.md` 已形成一套可复用规则:
|
||
|
||
```text
|
||
source proof ready
|
||
native runtime readiness checked
|
||
probe disabled by default
|
||
ENABLE_*_RUNTIME_PROBE=1 才运行真实 host runtime
|
||
缺少 host runtime 时 skip,不失败
|
||
已有 LinuxCNC runtime 冲突时 blocked,不抢占
|
||
execution_enabled=0
|
||
promotion_allowed=0 until Node/WASM/browser proof also passes
|
||
```
|
||
|
||
当前已有可参考脚本:
|
||
|
||
```text
|
||
wasm-port/tests/native/probe_millturn_user_m_runtime.sh
|
||
wasm-port/tests/native/probe_tool_db_runtime.sh
|
||
wasm-port/tests/native/probe_python_remap_runtime.sh
|
||
```
|
||
|
||
后续 `probe_trt_task_hal_runtime.sh` 必须照这个模式写,尤其是:
|
||
|
||
- 检查 `linuxcnc`、`halcmd`、`halrun`、`milltask` 或所需命令;
|
||
- 默认只报告 readiness,不执行独占 runtime;
|
||
- 显式 opt-in 后才启动 native runtime;
|
||
- 如果发现已有 `linuxcncsvr -ini` 或 `rtapi_app load`,报告 blocked;
|
||
- 输出 key/value artifact,且默认保持 `promotion_allowed=0`。
|
||
|
||
### 4.4 Web/virtual HAL user-M proof 可借鉴
|
||
|
||
`textbak/text28.txt` 的 L4-USER-M-PROCESS 记录说明:millturn `M429 -> M129 -> turn`、`M428 -> M128 -> mill` 已接入 Web/virtual HAL 状态 proof,验证了:
|
||
|
||
```text
|
||
motion.switchkins-type
|
||
motion.analog-out-03
|
||
kinstype.is-0 / kinstype.is-1
|
||
ini.x.min_limit / ini.x.max_limit
|
||
ini.z.min_limit / ini.z.max_limit
|
||
```
|
||
|
||
这对 TRT `M428/M429/M430` 的 task/HAL 同步很有价值:可复用状态目标、guard pin、source-boundary report 的写法。但它仍然不执行 arbitrary external user-M process,不解除 native promotion。
|
||
|
||
### 4.5 kinematics 和 HAL shim 已有注意事项
|
||
|
||
`textbak/text39.txt`、`textbak/text40.txt`、`textbak/text41.txt` 记录了 kinematics WASM ABI 和 HAL shim 经验:
|
||
|
||
- `wasm-port/runtime/core/shims/hal.h` 已是 C ABI 边界;
|
||
- `linuxcnc_hal_adapter.cpp` 需要对 C/C++ 调用者保持一致 ABI;
|
||
- kinematics C 源可能直接调用 `hal_*`,所以 task/HAL runtime 的 HAL API 不能只做 JS wrapper;
|
||
- kinematics ready 不能等同于 interpreter/remap/full-process ready。
|
||
|
||
后续新增 `linuxcnc_hal_runtime.hh/.cpp` 时,应兼容现有 `hal.h` 和 `linuxcnc_hal_adapter.hh`,不要另起一套不兼容 HAL 类型定义。
|
||
|
||
### 4.6 应写入后续实现的复用点
|
||
|
||
后续代码实施时,优先按下面映射复用:
|
||
|
||
| 后续阶段 | 复用来源 | 用法 |
|
||
| --- | --- | --- |
|
||
| 阶段 1 Native 对照探针 | `probe_millturn_user_m_runtime.sh` | 复制 opt-in、skip、blocked、key/value 输出模式 |
|
||
| 阶段 2 HAL runtime | `linuxcnc-hal.js`、`hal.h`、`linuxcnc_hal_adapter.hh` | 复用 pin 类型、family、source evidence、C ABI 类型 |
|
||
| 阶段 3 Motion HAL sync | `createVirtualHalMotionControllerMatrixReport()` | 把 matrix 从 virtual HAL fixture 升级为 task/motion/HAL runtime 对比 gate |
|
||
| 阶段 5 Machine-file session | `linuxcnc-machine-file-staging.js`、`snapshot-store.js` | 复用 OPFS 文件和 virtual HAL session payload 结构 |
|
||
| 阶段 6 SWITCHKINS | `VIRTUAL_HAL_MILLTURN_USER_M_PROCESS_BOUNDARY` | 复用 guard pin / state target / source-boundary report 方法 |
|
||
| 阶段 8 Full boundary | `full-process-boundary-design.md` | 保持 promotion lock,直到 native/WASM/browser 全链路通过 |
|
||
|
||
## 5. 分阶段实现
|
||
|
||
### 阶段 0:源码和构建清单补齐
|
||
|
||
目标:
|
||
|
||
- 把 task、motion、HAL、NML 相关源码加入可追溯清单;
|
||
- 明确哪些源文件参与 WASM 构建,哪些只用于 native 对照;
|
||
- 禁止直接从 JS 手写 task/HAL 语义。
|
||
|
||
要编写或更新的文件:
|
||
|
||
```text
|
||
wasm-port/tools/source-manifest.txt
|
||
wasm-port/docs/source-reuse-map.md
|
||
web-rtcp-5axis-sim-plan/docs/traceability-matrix.md
|
||
```
|
||
|
||
具体步骤:
|
||
|
||
1. 在 `source-manifest.txt` 中加入 `src/emc/task`、`src/emc/motion`、`src/hal`、`src/libnml`、`src/emc/nml_intf` 的必要文件。
|
||
2. 建立 manifest 校验脚本,比较 `linuxcnc/` 和 `wasm-port/vendor/linuxcnc/` 的 hash。
|
||
3. 对 `emctaskmain.cc`、`emctask.cc`、`taskintf.cc`、`emccanon.cc` 做编译依赖扫描,列出必须 shim 的函数。
|
||
4. 对 `hal_lib.c`、`hal_priv.h`、`threads.c`、motion HAL pin 定义做依赖扫描,列出 HAL API 最小集合。
|
||
5. 验收时输出机器可读 artifact:
|
||
|
||
```text
|
||
task_hal_source_manifest_ready=1
|
||
task_source_count>0
|
||
hal_source_count>0
|
||
motion_source_count>0
|
||
```
|
||
|
||
### 阶段 1:Native 对照探针
|
||
|
||
目标:
|
||
|
||
- 先用 host-native LinuxCNC 证明期望行为;
|
||
- 不修改 Web runtime;
|
||
- 如果本机没有 LinuxCNC runtime 命令,探针允许 skip,但不得 promoted。
|
||
- 复用 `textbak` 中已有 native opt-in probe 规则,避免默认启动或抢占 LinuxCNC host runtime。
|
||
|
||
要编写的文件:
|
||
|
||
```text
|
||
wasm-port/tests/native/probe_trt_task_hal_runtime.sh
|
||
wasm-port/runtime/core/linuxcnc_wrap/linuxcnc_task_hal_native_probe.cpp
|
||
wasm-port/build/native/task-hal-reference/*.json
|
||
```
|
||
|
||
固定序列:
|
||
|
||
```text
|
||
SET_STATE ON
|
||
SET_MODE AUTO
|
||
OPEN impeller-7bl-xyzac.ngc
|
||
RUN
|
||
wait until first motion
|
||
PAUSE
|
||
RESUME
|
||
run through M428/M429 switchkins segment
|
||
ABORT
|
||
```
|
||
|
||
必须记录:
|
||
|
||
```text
|
||
task.state
|
||
task.mode
|
||
task.interpState
|
||
task.execState
|
||
motion.program-line
|
||
motion.motion-type
|
||
motion.switchkins-type
|
||
motion.coord-mode
|
||
motion.teleop-mode
|
||
motion.in-position
|
||
joint.N.motor-pos-cmd
|
||
joint.N.motor-pos-fb
|
||
axis pose / commanded pose / feedback pose
|
||
analog-out-03
|
||
synch digital/analog IO
|
||
```
|
||
|
||
验收:
|
||
|
||
```text
|
||
native_task_hal_probe=ok
|
||
native_probe_status=passed or skipped_missing_host_runtime
|
||
promotionAllowed=false until WASM comparison passes
|
||
```
|
||
|
||
### 阶段 2:HAL 内存模型和线程调度器
|
||
|
||
目标:
|
||
|
||
- 用 LinuxCNC HAL API 名称建立 WASM 内部 HAL registry;
|
||
- 支持 pin、signal、param、net、alias;
|
||
- 支持确定性 thread/function 调度。
|
||
- 复用 `linuxcnc-hal.js` 中的 HAL family/source evidence 和 `hal.h` 的类型定义。
|
||
|
||
参考源码:
|
||
|
||
```text
|
||
linuxcnc/src/hal/hal_lib.c
|
||
linuxcnc/src/hal/hal_priv.h
|
||
linuxcnc/src/hal/components/threads.c
|
||
wasm-port/runtime/core/shims/hal.h
|
||
wasm-port/runtime/core/linuxcnc_wrap/linuxcnc_hal_adapter.hh
|
||
```
|
||
|
||
要编写的文件:
|
||
|
||
```text
|
||
wasm-port/runtime/core/linuxcnc_wrap/linuxcnc_hal_runtime.hh
|
||
wasm-port/runtime/core/linuxcnc_wrap/linuxcnc_hal_runtime.cpp
|
||
wasm-port/runtime/core/linuxcnc_wrap/linuxcnc_halcmd_runtime.cpp
|
||
wasm-port/tests/wasm/node/verify_hal_runtime.sh
|
||
wasm-port/runtime/sdk/src/linuxcnc-hal.js
|
||
```
|
||
|
||
必须实现的 C/C++ API:
|
||
|
||
```text
|
||
hal_init
|
||
hal_ready
|
||
hal_exit
|
||
hal_malloc
|
||
hal_pin_bit_new
|
||
hal_pin_float_new
|
||
hal_pin_s32_new
|
||
hal_pin_u32_new
|
||
hal_pin_*_newf
|
||
hal_param_*_newf
|
||
hal_get_pin_value_by_name
|
||
hal_get_signal_value_by_name
|
||
hal_get_param_value_by_name
|
||
hal_link
|
||
hal_unlink
|
||
hal_set_p
|
||
hal_get_p
|
||
hal_create_thread
|
||
hal_add_funct_to_thread
|
||
hal_del_funct_from_thread
|
||
hal_start_threads
|
||
hal_stop_threads
|
||
```
|
||
|
||
必须实现的 WASM C ABI:
|
||
|
||
```c
|
||
int lchal_init_runtime(void);
|
||
int lchal_load_hal_file(const char *path, const char *text);
|
||
int lchal_set_pin_float(const char *name, double value);
|
||
int lchal_set_pin_s32(const char *name, int value);
|
||
int lchal_set_pin_bit(const char *name, int value);
|
||
int lchal_get_pin_json(const char *name, char *out, int out_len);
|
||
int lchal_get_snapshot_json(char *out, int out_len);
|
||
int lchal_step_threads(long period_ns, int cycles);
|
||
int lchal_reset_runtime(void);
|
||
```
|
||
|
||
编写要点:
|
||
|
||
1. 所有 HAL 值必须保存在 C/C++ runtime 内部,不放在 JS 里当语义源。
|
||
2. `net` 只建立 pin 到 signal 的绑定,值传播由 thread step 或显式 set/get 触发。
|
||
3. `halcmd` 先支持 TRT sim config 需要的最小命令:`loadrt`、`addf`、`net`、`setp`、`gets`。
|
||
4. 对 `loadusr`、外部进程、真实驱动组件必须返回 blocked evidence,不得静默忽略。
|
||
5. 每次 `lchal_step_threads()` 记录 cycle、thread name、function name、changed pins。
|
||
|
||
验收:
|
||
|
||
```text
|
||
hal_runtime_registry=ok
|
||
hal_thread_scheduler=ok
|
||
hal_net_signal_propagation=ok
|
||
loadusr_blocked_evidence=ok
|
||
```
|
||
|
||
### 阶段 3:Motion realtime 同步最小闭环
|
||
|
||
目标:
|
||
|
||
- 把 LinuxCNC motion controller 以确定性 servo cycle 方式接入;
|
||
- task 发出的 trajectory/jog 命令进入 motion command queue;
|
||
- motion controller 每周期更新 status 和 HAL pins。
|
||
- 把现有 virtual HAL motion controller matrix 改造为 task/motion/HAL runtime 的对比 gate。
|
||
|
||
参考源码:
|
||
|
||
```text
|
||
linuxcnc/src/emc/motion/usrmotintf.h
|
||
linuxcnc/src/emc/motion/motion.h
|
||
linuxcnc/src/emc/motion/motion.c
|
||

|
||
linuxcnc/src/emc/motion/mot_priv.h
|
||
linuxcnc/src/emc/task/taskintf.cc
|
||
```
|
||
|
||
要编写的文件:
|
||
|
||
```text
|
||
wasm-port/runtime/core/linuxcnc_wrap/linuxcnc_motion_runtime.c
|
||
wasm-port/runtime/core/linuxcnc_wrap/linuxcnc_motion_runtime.h
|
||
wasm-port/tests/wasm/node/verify_motion_hal_sync.sh
|
||
wasm-port/runtime/sdk/src/linuxcnc-motion.js
|
||
```
|
||
|
||
必须实现的 C ABI:
|
||
|
||
```c
|
||
int lcmot_init_from_ini(const char *ini_path, const char *ini_text);
|
||
int lcmot_write_command_json(const char *json);
|
||
int lcmot_step_servo(long period_ns, int cycles);
|
||
int lcmot_read_status_json(char *out, int out_len);
|
||
int lcmot_read_hal_snapshot_json(char *out, int out_len);
|
||
int lcmot_reset(void);
|
||
```
|
||
|
||
编写要点:
|
||
|
||
1. 优先复用 `emcmot_status_t`、`emcmot_command_t`、`emcmot_config_t`,避免新建 Web 专用 motion struct。
|
||
2. `usrmotWriteEmcmotCommand()` 在 WASM 中改为写入内存队列。
|
||
3. `usrmotReadEmcmotStatus()` 在 WASM 中从同一 runtime snapshot 读取。
|
||
4. `emcmotController(void *arg, long period)` 按固定周期调用。
|
||
5. motion HAL pins 必须按 `mot_priv.h` 中的方向和名称输出。
|
||
6. 至少覆盖 `EMC_JOG_*`、`EMC_TRAJ_LINEAR_MOVE`、`EMC_TRAJ_CIRCULAR_MOVE`、`EMC_TRAJ_PAUSE`、`EMC_TRAJ_RESUME`、`EMC_TRAJ_ABORT`、override 类命令。
|
||
|
||
验收:
|
||
|
||
```text
|
||
motion_hal_servo_cycle=ok
|
||
motion_program_line_hal_sync=ok
|
||
switchkins_type_hal_sync=ok
|
||
jog_motion_status_sync=ok
|
||
```
|
||
|
||
### 阶段 4:Task runtime 移植
|
||
|
||
目标:
|
||
|
||
- 让 Web runtime 使用 LinuxCNC task loop 处理 operator command;
|
||
- `RUN/PAUSE/RESUME/STOP/ABORT/MDI/JOG` 不再只走 Web policy mirror;
|
||
- task status、exec state、interp state 来自 LinuxCNC task runtime。
|
||
|
||
参考源码:
|
||
|
||
```text
|
||
linuxcnc/src/emc/task/task.hh
|
||
linuxcnc/src/emc/task/emctask.cc
|

|

web-rtcp-5axis-sim-plan/app/src/runtime/linuxcnc-task-hal-worker-client.js
|

```
|
||
|
||
必须实现的 C ABI:
|
||
|
||
```c
|
||
int lctask_init_session(const char *session_json);
|
||
int lctask_stage_file(const char *path, const char *text);
|
||
int lctask_open_program(const char *path);
|
||
int lctask_send_command_json(const char *command_json);
|
||
int lctask_run_cycles(long task_period_ns, long servo_period_ns, int task_cycles);
|
||
int lctask_read_status_json(char *out, int out_len);
|
||
int lctask_read_events_json(char *out, int out_len);
|
||
int lctask_reset_session(void);
|
||
```
|
||
|
||
command JSON 最小格式:
|
||
|
||
```json
|
||
{"type":"EMC_TASK_SET_STATE","state":"ON"}
|
||
{"type":"EMC_TASK_SET_MODE","mode":"AUTO"}
|
||
{"type":"EMC_TASK_PLAN_RUN","line":0}
|
||
{"type":"EMC_TASK_PLAN_PAUSE"}
|
||
{"type":"EMC_TASK_PLAN_RESUME"}
|

{"type":"EMC_TASK_ABORT"}
|
||
{"type":"EMC_TASK_PLAN_EXECUTE","mdi":"G0 X1"}
|
||
{"type":"EMC_JOG_INCR","axis":"X","distance":1,"velocity":60}
|
||
```
|
||
|
||
编写要点:
|
||
|
||
1. `emcTaskOnce()` 是 task loop 的首选入口;不能直接复制 Web 现有 `linuxcnc-task-policy.js` 的判断结果作为完成状态。
|
||
2. `RCS_CMD_CHANNEL`、`RCS_STAT_CHANNEL`、NML channel 在 WASM 中用 in-process queue shim 替代,消息类型仍来自 `emc.hh`。
|
||
3. `emcTaskQueueCommand()` 输出的 `EMC_TRAJ_*` 消息必须进入 motion runtime,而不是只生成 UI event。
|
||
4. `emccanon.cc` 生成的 canonical motion 要同时进入 task queue evidence、motion command queue、TP planner timing evidence、G-code 当前行映射。
|
||
5. task cycle 和 servo cycle 分开,例如每个 10 ms task cycle 运行 10 个 1 ms servo cycle。

### 阶段 5:TRT machine-file session 接入
|
||
|
||
目标:
|
||
|
||
- 复用现有 OPFS machine-file staging;
|
||
- task/HAL runtime 读取同一 INI、HAL、tool table、remap、G-code 文件;
|
||
- `xyzac-trt` 和 `xyzbc-trt` 都能跑 smoke。
|
||
|
||
要更新的文件:
|
||
|
||
```text
|
||
web-rtcp-5axis-sim-plan/app/src/runtime/linuxcnc-machine-file-staging.js
|
||
web-rtcp-5axis-sim-plan/app/src/runtime/linuxcnc-interpreter-runtime.js
|
||
web-rtcp-5axis-sim-plan/app/src/state/store.js
|
||
web-rtcp-5axis-sim-plan/app/src/ui/gmoccapy-shell.js
|
||
```
|
||
|
||
具体步骤:
|
||
|
||
1. 给 staging 结果增加 `taskHalSession`,记录 INI、HAL、tool table、remap、program path。
|
||
2. Worker 初始化时把所有 staged 文件写入 Emscripten FS。
|
||
3. `LOAD_LINUXCNC_GCODE_SOURCE` 后自动调用 `lctask_open_program()`。
|
||
4. `RUN` 优先走 task/HAL runtime;失败时可 fallback 到现有 interpreter runtime,但 UI 必须显示 fallback boundary。
|
||
5. G-code panel 当前行改用 task/motion status 的 `motion.program-line`,interpreter canonical line 只作为辅助 evidence。

|
||
gcode_current_line_from_motion_hal=ok
|
||
```
|
||
|
||
### 阶段 6:SWITCHKINS 和 M428/M429/M430 同步
|
||
|
||
目标:
|
||
|
||
- `M428/M429/M430` 的状态变化由 LinuxCNC task/remap/motion/HAL 链路驱动;
|
||
- Web runtime 不再单独用 JS 事件切换 RTCP 作为主语义源。
|
||
|
||

|
||
linuxcnc/src/emc/kinematics/xyzbc-trt-kins.c
|
||
```
|
||
|
||
具体步骤:
|
||
|
||
1. 在 HAL runtime 中保证 `motion.switchkins-type` 可读写。
|
||
2. 在 remap execution 中保留 `M68`/`M66` 同步语义。
|
||
3. motion servo cycle 读取 `motion.switchkins-type` 后调用 kinematics switch。
|
||
4. Three.js 和 DRO 从 task/HAL snapshot 中读取 `rtcpState`、`kinsType`、tool axis。
|
||
5. 当前已有的 JS switchkins event 只保留为 diagnostics fallback,不作为 promoted source。

### 阶段 7:浏览器 Worker 和 store 接线
|
||
|
||
目标:
|
||
|
||
- task/HAL runtime 在 Worker 内运行;
|
||
- UI 不直接阻塞;
|
||
- status snapshot 驱动 gmoccapy UI。
|
||
|

|
||
```
|
||
|
||
### 阶段 8:Full boundary 提升
|
||
|
||
目标:
|
||
|
||
- 只有所有 task/HAL smoke 通过后,才修改 full boundary;
|
||
- 把 blocker 从当前状态移除。
|
||
|
||
提升条件:
|
||
|
||
```text
|
||
kinematicsReady=true
|
||
interpreterReady=true
|
||
plannerRuntimeReady=true
|
||
machineFileStagingReady=true
|

|
||
nativeTaskReady=true
|
||
nativeHalSyncReady=true
|
||
taskHalComparisonReady=true
|
||
```
|
||
|
||
`createFullLinuxCncExecutionBoundary()` 修改规则:
|
||
|
||
```text
|
||
nativeTaskReady = taskHal?.summary?.taskRuntimeReady === true
|
||
nativeHalSyncReady = taskHal?.summary?.halSyncReady === true

```
|
||
|
||
semantic boundary 名称:
|
||
|
||
```text
|
||
linuxcnc_task_motion_hal_wasm_simulation_runtime
|
||
```
|
||
|
||
不允许的提升:
|
||
|
||
- 只有 Web policy mirror 通过;
|
||
- 只有 interpreter canonical events 通过;
|
||
- 只有 TP timing 通过;
|
||
- 只有 HAL source map 或 PyVCP schema 通过;
|
||
- 没有 task cycle 与 HAL servo cycle 对比 artifact。
|
||
|
||
## 5. 详细编程顺序
|
||
|
||
建议严格按以下顺序写程序,避免一次性移植 task、HAL、motion 后难以定位问题。
|
||
|
||
1. 新建 `linuxcnc_hal_runtime.hh/.cpp`,只实现 pin registry、`hal_init()`、`hal_ready()`、`hal_malloc()`、`hal_pin_*_newf()`。
|
||
2. 写 `verify_hal_runtime.sh`,证明 pin 创建、set/get、snapshot JSON 可用。
|
||
3. 增加 signal/net/link,写 `halcmd_runtime.cpp` 支持 `net` 和 `setp`。
|
||
4. 增加 thread registry,支持 `hal_create_thread()`、`hal_add_funct_to_thread()`、`lchal_step_threads()`。
|
||
5. 接入 motion HAL pin 初始化,先让 `motion.switchkins-type`、`motion.program-line`、`joint.0.motor-pos-cmd` 能在 snapshot 中出现。
|
||
6. 新建 `linuxcnc_motion_runtime.c`,实现 in-memory `usrmotWriteEmcmotCommand()` 和 `usrmotReadEmcmotStatus()`。
|
||
7. 调用 `emcmotController()` 运行固定 servo cycles,先验证空闲状态 heartbeat 增长。
|
||
8. 接入 `EMC_TRAJ_LINEAR_MOVE`,验证 motor/carte command position 随周期变化。
|
||
9. 接入 JOG 命令,验证 FREE/TELEOP/COORD 模式切换和 HAL pins。
|
||
10. 新建 in-process NML queue shim,消息类型必须来自 `emc.hh`。
|
||
11. 编译 `emctask.cc`、`emctaskmain.cc`、`taskintf.cc`、`emccanon.cc` 的最小 task runtime。
|
||
12. 实现 `lctask_init_session()` 和 `lctask_send_command_json()`,先跑 `SET_STATE`、`SET_MODE`。
|
||
13. 实现 `lctask_open_program()`,读取 staged G-code。
|
||
14. 实现 `RUN/PAUSE/RESUME/ABORT`,验证 task status 和 motion status 同步。
|
||
15. 接入 existing interpreter/remap machine-file path,确保 M428/M429/M430 不再被 Web 主逻辑单独处理。
|
||
16. 把 task/HAL runtime 包成 SDK `linuxcnc-task-hal.js`。
|
||
17. 写 Web Worker client,加入 sequence guard,防止旧 status 覆盖新 session。
|
||
18. 修改 store:优先 task/HAL runtime,失败时保留现有 interpreter fallback 并显示 fallback boundary。
|
||
19. 修改 UI diagnostics,显示 task/HAL readiness 和 cycle counters。
|
||
20. 修改 full boundary,只有全部新 smoke 通过后才把 `nativeTaskReady`、`nativeHalSyncReady` 置为 true。
|
||
|
||
## 6. 验收测试矩阵
|
||
|
||
Node smoke:
|
||
|
||
```text
|
||
node web-rtcp-5axis-sim-plan/tests/node/verify_linuxcnc_task_hal_runtime.mjs
|
||

|
||
npm --prefix web-rtcp-5axis-sim-plan/app run smoke
|
||
```
|
||
|

|
||
ENABLE_TRT_TASK_HAL_RUNTIME_PROBE=1 bash wasm-port/tests/native/probe_trt_task_hal_runtime.sh
|
||
```
|
||
|
||
最终 gate:
|
||
|
||
```text
|

linuxcnc_task_hal_wasm_build=ok
|

full_execution_boundary_smoke=ok
|
||
```
|
||
|
||
## 7. 完成定义
|
||
|
||
只有同时满足以下条件,才允许把文档和 UI 中的 blocker 改为完成:
|
||
|
||
```text
|
||
task commands are accepted by LinuxCNC task-derived runtime
|
||
task runtime drives motion command queue
|
||
motion runtime advances through deterministic servo cycles
|
||
HAL pins are created from LinuxCNC-style HAL API
|
||
HAL thread/function scheduler advances with servo cycles
|
||
M428/M429 switchkins changes are visible through motion.switchkins-type
|
||
G-code current line comes from motion/task status
|
||
Node smoke passes
|
||
Browser source smoke passes
|
||
Browser dist smoke passes
|
||
Optional native LinuxCNC probe either passes or is explicitly skipped without promotion dependency
|
||
Traceability document records every source file and boundary
|
||
```
|
||
|
||
完成后仍必须在 UI 和文档里显示:
|
||
|
||
```text
|
||
hardwareDrive=false
|
||
hostRealtimeKernel=false
|
||
externalUserMProcessReady=false unless separately implemented
|
||
toolDbProcessReady=false unless separately implemented
|
||
```
|
