feat(scheduler)!: 中断/排队两类别模型 + 插件声明 L1-L3、L4 内核独占
用户澄清推翻了早期设计的三处前提,本提交按新模型重做调度核心(行为有意变化): 1) 类别由注入 API 决定,与通道名无关 - InjectInterrupt* -> TaskInterrupt(带级别,可被严格更高级中断打断) - InjectText*/InjectInputSync*/内核自循环 -> TaskQueued(无级别,可被任何中断打断) - 删除按通道名推断的 taskLevel():qq 走 InjectInterruptTextOpts,本就是中断 2) 级别只属于中断 - 插件在 InjectOptions.Priority 声明 L1-L3(空/非法降级 L1,声明 L4 夹到 L3) - L4 内核独占:新增 raiseKernelInterrupt(panic / selfip);requestKernelPreempt 不夹取 - panic 现在产生一条带 kernel 标记的 L4 中断;L4 自身 panic 不再产生新 L4(防自我放大) 3) 选择结构:四容器固定次序,删除统一比较器 - immediate(抢占者立即运行)-> 中断队列 L4..L1 -> 栈顶(与队头比级别) -> 排队 FIFO - 删除 pickTaskIndex/taskBefore 与“同级 pending 优先”补丁(根因是抢占者进了队列) - 中断栈上界改为结构推论 = 4(= 中断级数);删除“超限转 pendingInterrupts”降级 公开 SDK(feature 分支有意新增,纯追加):InjectOptions.Priority + PriorityL1/2/3; 内核 io / proc 桥 / 插件模板同步透传。 设计稿 §2/§3/§4.1/§6.3/§9/§11/§12/§13/§15 按新模型重写。 验收:go build/vet 干净;go test ./... 37 包 ok 0 FAIL;-race 全绿; e2e(抢占-挂起-恢复)+ 压力(200 排队 + 50 中断,L1/L2/L3 轮转)通过。
