open-iov.git/STATE-CURRENT.md, branch master Open-IOV vGPU-IO: host-side GSP emulation for unmodified NVIDIA guest drivers https://git.vgpu.io/open-iov.git/atom?h=master 2026-10-07T12:36:26+00:00 STATE-CURRENT: 2026-10-07 ~01:15 snapshot - 0xc5c0 construct GREEN + forwarded QMD enqueues/schedules; engine-core execution is the remaining wall 2026-10-07T12:36:26+00:00 Arthur Hanson Rasmusson arthur@vgpu.io 2026-10-07T12:36:26+00:00 urn:sha1:d6ca56771c49531e5e6160f97dbf94067a57a0af (a) The TSG+share lane's compute-object construct returns success after a 10-entry VA-only booking promote books the server's per-VAS ctx-buffer maps (a mapped MAIN promote alone leaves them unbooked because the construct skips its own mapping once MAIN is initialized). (b) The forwarded guest QMD now enqueues and is scheduled: the missing real-client step was the lane-enable tail (CILP preemption mode, timeslice 0x800, device scheduling enable); the front-end deposit, the scheduler CWD entry (QMD id) and the engine-context load (VALID) all appear. Register ground truth from the working distribution driver during live CUDA plus the read-only sampler/analyzer are committed under tools/gr-regs/. Remaining wall: the GR engine core does not execute the scheduled QMD (no release written anywhere, no visible fault); ranked next moves in the local handoff. Host clean, GPU green, no reboots.

Add an options section listing candidate techniques that would accelerate debugging toward end-to-end CUDA (deterministic fault injection, offline pump model, structured host tracing, guest-memory forensics, GR-wall metadata/golden reference/static-analysis throughput, cheaper supervised cycles, concurrency checks, tooling automation) - explicitly not directives, each requiring an eng-ops admission record.
