| | | | | | | | | | | | | | physical-backend guest-wiring design - STATE-CURRENT snapshot 2026-10-01 21:05: the host RM-client ladder now allocates VAS+PDB+TSG+channel and executes a real 4 KiB VA-mode CE copy (semaphore released, dst==src) on the physical engine; next is wiring the live session into the guest-facing mdev/vfio path. - docs/03-architecture/11-physical-backend-guest-wiring.md: phased design (P0-P6) for bridging the physical backend into the guest-facing emulation, with the seam table, lifecycle changes and static-config flow. - docs/README.md: reading order updated for the new document; execution status refreshed.

* STATE-CURRENT: real-release rc=0 chain reached; execution backend is the ↵Arthur Hanson Rasmusson2026-09-30
| | | | | | | | | | | | frontier - the per-push 8 s stall was pump bookkeeping (release-seen keyed on the unchanged tracker-semaphore VA; rewind replays returning to the CE grace path) - fixed; real-release init now completes in ~1 min - the content rescue now parses the real method encoding, so NON_INC-headed pushes validate and their releases land - the queued launch's module image reaches the emulated vidmem; execution on real hardware (docs/03-architecture/08 backend) is the next project
* STATE-CURRENT: no-pin release delivery committed; real-release init reaching ↵Arthur Hanson Rasmusson2026-09-30
| | | | | | | | device count - 6ec799c delivers UVM tracking releases without host-side pins - one real-release no-watcher cycle reached cudaGetDeviceCount success - cycles continue; execution backend remains the gating item
* STATE-CURRENT: no-watcher cycles iterating (module rebuilt from the ↵Arthur Hanson Rasmusson2026-09-30
| | | | | | | in-flight edit) - three real-release cycles without kprobes/watchers; no textual result yet - frontier unchanged: real-release runtime init and the execution backend
* STATE-CURRENT: activity resumed - no-watcher real-release runtime cyclesArthur Hanson Rasmusson2026-09-30
| | | | | | - fresh module per cycle without kprobes/watchers; early observation: a compute-channel entry stalls with a failure notifier - frontier unchanged: real-release runtime init and the execution backend
* STATE-CURRENT: runtime client reaches kernel launch; execution backend is ↵Arthur Hanson Rasmusson2026-09-30
| | | | | | | | the next wall - runtime init rc=0 (cudaGetDeviceCount/SetDevice/alloc/HtoD/launch accepted) - fixed the legacy clock-domain probe replies that blocked runtime init - next: real-release runtime init and physical-GPU execution of queued work
* STATE-CURRENT: PD writes proven live; runtime client past registration; ↵Arthur Hanson Rasmusson2026-09-30
| | | | | | | | canonical reply fix - page-directory entry writes captured and validated; 64/64 baseline stays - vectorAdd client now fails after registration in libcuda (rc=3), no kernel error - BAR-info canonical reply-size bug fixed; one cache mismatch remains
* STATE-CURRENT: quiet logging landed; baseline verified twice; PD-capture ↵Arthur Hanson Rasmusson2026-09-30
| | | | | | | | task next - dmesg diagnostics gated behind default-off sema_dbg; 64/64 with a 520-line log - staging buffer kept resolvable via streamed pins; PD-entry capture remains - note the guest-side kernel fault observed in serial
* STATE-CURRENT: payload roundtrip 64/64 restored by the page-table ↵Arthur Hanson Rasmusson2026-09-30
| | | | | | | | publication capture - the device-to-host destination now resolves; baseline green again in live runs - frontier/active-work notes updated: land the capture fix, then the runtime vectorAdd client

| | | | targeted-fallback/retry work
* docs: retire the 2026-09-21 STATE.md snapshotArthur Hanson Rasmusson2026-09-30
| | | | | | | - remove the superseded flat state page; current state lives in STATE-CURRENT.md and the docs tree - update the historical-material note in docs/README and the STATE-CURRENT header/see-also references
* STATE-CURRENT: runtime bring-up started; runtime buffer translations are the ↵Arthur Hanson Rasmusson2026-09-30
| | | | | | | | | wall - harness runs nvidia-smi and a static-runtime vectorAdd-style client - page-table walk succeeds at scale; larger runtime buffers still fail translation (host copies report missing entries) - frontier/active-work notes updated
* STATE-CURRENT: full driver-API smoke test passes with payload 64/64Arthur Hanson Rasmusson2026-09-30
| | | | | | | - milestone: cuCtxCreate through cuCtxDestroy with correct data roundtrip - GMMU walk decode fixed (real entry encoding); DtoH copy-engine-on-compute allowed for trusted injected pushes - ladder/diagrams/rails updated; next rung is real CUDA workloads
* STATE-CURRENT: payload path found (compute-class inline DMA); page-table ↵Arthur Hanson Rasmusson2026-09-30
| | | | | | | | | walk is the wall - smoke test ends ALL OK; data roundtrip pending the GPU-VA walk - HtoD identified as a GRCE inline-data DMA and decoded; destination translation is the remaining blocker - frontier/rail refreshed
* sema-svc: run CE work before its release, grace unreadable CE entries, ↵Arthur Hanson Rasmusson2026-09-30
| | | | | | | | | | | | | | | | | | | payload-pattern audit - CE LAUNCH_DMA releases are now applied after the push's collected work runs: the client reads copied data as soon as it observes the release, so release-first let cuMemcpyDtoH observe a copy that had not executed. - Unreadable CE entries stay pending for a grace window (sema_ce_grace_ms, default 8s) before the release fallback consumes them, so a translation that lands within a service pass lets the push be decoded and its work executed instead of being dropped. - sema_copy_pat matches an 8-byte value against every copy's src/dst first word and scans decoded pushes for it, naming the submission that carries a known payload regardless of size/encoding. - sema-dma-skip logs transfer-shaped launches that collect no op; op log lines carry the channel handle; LAUNCH_DMA inventory follows OPS_LOG. - A real release application now records the release VA, so decoded pushes no longer trigger a spurious fake release.
* STATE-CURRENT: cuCtxCreate 999 root-caused and fixed; UVM runtime progressArthur Hanson Rasmusson2026-09-30
| | | | | | | | - GR-info indices 7/9/0x17/0x22 were zero in the emulation (shader-pipe sub-count among them); filling real-device values clears the previously fatal context check - client now runs inside UVM for minutes instead of failing in seconds - next wall: push-data operand translation (fix in); frontier notes updated
