* STATE-CURRENT + docs: record the freeze fix and the P2/P3 guest-wiring landingsArthur Hanson Rasmusson2026-10-02
| | | | | | | | - STATE-CURRENT snapshot moves to the P3 frontier: the host-freeze latch and readiness gates are validated, the static identity overlay and the read-only control forwarding are landed and live-verified - the physical-backend guest-wiring design is now marked P0-P3 implemented with the P2/P3 acceptance results
* STATE-CURRENT: 01:25 check-back - G0 freeze fix validated 2/2; P2 guest ↵Arthur Hanson Rasmusson2026-10-02
| | | | identity overlay live (GREEN); LIVE=0 control did not pass
* docs: gate post-1.0 host acceleration as do-not-implementArthur Hanson Rasmusson2026-10-02
| | | | | | | | | | Clarify in the post-1.0 record and the public status page that host-native acceleration / host display is a stretch goal we are only considering: do not block on it, pursue it, or design around it. It is never reached automatically, requires an explicit human decision after all baseline goals are complete (and only once there is no known risk), and may be scrapped on architectural grounds. No aspect of the baseline software may be designed toward it. No baseline design or code changes.
* STATE-CURRENT: 23:12 check-back - guest-wiring P1 lifecycle landed and ↵Arthur Hanson Rasmusson2026-10-01

| | | | | | | | | | | | | | 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 and the architecture docs now describe the observed order (FWSEC -> Booter Load -> RISC-V active -> event 0x1002 run-sequencer -> 0x1001 init-done), the four-handoff-bit clean-release constraint, and the --boot/--keep harness contract.

* 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

| | | | | | | | 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: 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
