| | | | drafted
* STATE-CURRENT: real-release rc=0 chain reached; execution backend is the ↵Arthur Hanson Rasmusson11 days
| | | | | | | | | | | | 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 Rasmusson11 days
| | | | | | | | device count - 7f84797 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 Rasmusson11 days
| | | | | | | 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 Rasmusson11 days
| | | | | | - 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 Rasmusson12 days
| | | | | | | | 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 Rasmusson12 days
| | | | | | | | 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 Rasmusson12 days
| | | | | | | | 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 Rasmusson12 days
| | | | | | | | 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
* STATE-CURRENT: baseline regression (DtoH destination translation) and the ↵Arthur Hanson Rasmusson12 days
| | | | targeted-fallback/retry work
* docs: retire the 2026-09-21 STATE.md snapshotArthur Hanson Rasmusson12 days
| | | | | | | - 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 Rasmusson12 days
| | | | | | | | | 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 Rasmusson12 days
| | | | | | | - 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 Rasmusson12 days
| | | | | | | | | 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 Rasmusson12 days
| | | | | | | | | | | | | | | | | | | 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 Rasmusson12 days
| | | | | | | | - 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
* docs: refresh current-state snapshot (20/20 GR releases land; failure not a ↵Arthur Hanson Rasmusson12 days
| | | | UVM wait)
* gsprm: reply-latency logging + param dump cap; guest-diag: CDT_PAUSE, ↵Arthur Hanson Rasmusson12 days
| | | | watcher reaping, wider CE stream window
* STATE-CURRENT: UVM registration milestone; frontier moved past itArthur Hanson Rasmusson12 days
| | | | | | | - registration wait named and unblocked (first CE channel tracker, value 3; early push-buffer pinning) - frontier now the post-registration window (external allocation burst) - note the recovered guest wedge on the fastest-pin configuration
* docs: add the full-system picture and interaction/scheduling diagramsArthur Hanson Rasmusson13 days
| | | | | | | | | | | | | | - new 03-architecture/09-full-system-picture.md: end-state map, GSP boot, guest init, RPC lifecycle, memory model, work path (bridge and end state), scheduling, isolation levels, KVM/mdev/VFIO, BAR/engine/channel/GMMU, portability, performance model, implementation/test status - new 03-architecture/10-interaction-and-scheduling.md: interaction inventory, control-plane call path, msgq element lifecycle, channel pump, concurrency, timing budgets, multi-tenant scheduling, teardown ordering, versioning - README: mermaid system diagram replaces the ASCII block; reading list extended and renumbered - component docs: GSP boot sequence, mdev/VFIO lifecycle, end-state interaction sequence; STATE-CURRENT links
* docs: record physical-GPU integration mechanism and refresh project statusArthur Hanson Rasmusson13 days
- add docs/03-architecture/08-physical-gpu-integration.md: interfaces that exist, mechanism options A-E, chosen path (module-owned GPU driven through its real GSP firmware), sharing policy, decision record - update 06-host-module-and-hybrid-model, 02-practical-challenges, system overview, known-knowns, docs/README reading order and CUDA-side docs to match - correct stale engine-topology/COPY14 blocker claims across the tree - add STATE-CURRENT.md as the dated public status snapshot
