- CONTRACT-P5E.md 2.5 said "the TEXTURE half keeps its wait because DrainTextureSubData clears the level's dirty flag on the accepted reply (D-D5; trailing)". The trailing is paid, so the clause now states the three facts that make that answer DERIVABLE on the wire arm (the emission gate IS the consumer question the applier's own acceptance belt asks; what remains is a loud bug class; a client-cancelled record still answers "not accepted"), where the wait moves to (SEG_STAGE), that MGPipeSubDataWantsItsReply stays the one place that decides, and the gate with its red-once. ResourceCreate and SetTextureParams are named as analyzed separately rather than swept in. - notes/p12/DEVICELOST-AND-UPLOAD-WAITS.md: 2.3 now carries the G1 A/B this machine ran - .text 13872002 bytes on both sides, 31746 symbols, 0 added / 0 removed, no per-symbol difference - instead of deferring it to CI, and 3 trades its "G1 not run" item for the device tooling (mgl-device/: launch-mc.py, gl-aliases.sh, start-phone-server.sh) the next round needs.
MGPipe:MobileGL 前后端拆分
做什么:在 MobileGL 的前端(处理应用的 GL 调用)和后端(调用 GLES / Vulkan 驱动)之间立一份显式接口——前端把状态变化推给后端,后端不再直接读前端的内存。有了这份接口,前后端可以放在两个线程、两个进程,甚至两台机器上运行。
做到哪了(2026-09-25):接口与拆分已完成到"两个进程、可经 TCP 跨机"。当前在做 P12:让 Android 上的 server 自己开窗口,把画面直接显示到屏幕上——审查后的主机定向测试和 Redmi 真机七项复测已通过;FCL 与跨机 TCP 两项验收仍未完成。→ CURRENT_STAGE_PROGRESS.md
一张图
应用的 GL 调用
→ 前端 MG_Impl:处理 GL 语义;在每条"做事的命令"(draw、clear…)之前,把状态变化整理成记录
→ MGPipe 接口(两张函数指针表,由调用目录 PipeCalls.def 生成)
→ 三选一:直接调用(单线程)│ 队列 → 另一个线程 │ 队列 → 另一个进程 / 另一台机器
→ 后端 MG_Backend:Espryt(GLES)/ Magma(Vulkan),按记录更新自己的状态并调用驱动
← 反向消息(错误、GPU 写回、窗口尺寸)按顺序回到前端
