debug/issue: ISSUE-0001 resolution update - m143 BAR1 root cause fixed; 9/10 gate with rep10-r10 wedge analysis recorded

debug/issue: issue register + ISSUE-0001 (reproducibility) + ISSUE-0002 (multiple kernels per VM)

2026-10-08T15:07:42+00:00

- debug/issue/README.md: when to file (nasty bugs only; default is no issues), template, numbering, lifecycle incl. solved/ move. - issue-number-1.md: guest CUDA is not reproducibly green (top priority); evidence discriminators, root cause (starved pool release translation), the three fixes landed, 10/10-boot validation plan. - issue-number-2.md: multiple kernels in one VM (sequential/concurrent/ simultaneous) must work; second-client wedge root-cause chain + plan. - tools/cuda-ab/smiley.cu: 4-pass vectorAdd that renders a 64x32 ASCII smiley from GPU-computed distance fields; ab.sh gains a generic 'push' mode so any WORKLOAD binary can be delivered to the guest.

risc-v-gsp-rm-debugger: B5 two-task attach + aggregate-state decode + docs 51/53 status

2026-10-06T23:57:20+00:00

- sim/libos_port.py: port-role model + two-task network (extintr handoff, cross-task send/reply, TASK_STATE_QUERY trap state) - sim/msgq_attach.py: image task discovery, bounded two-task schedule, second-task-frontier divergence fields (first ring poll still blocked on post-init resume + GSP_ARGUMENTS_CACHED handoff; no fabricated polls) - harness/state_decode.py: aggregate 'group: key=value' state parsing (20-gsp-phys-state-* dumps) + kv diff classification - tests: 127 green across the five observability modules - docs/51/53: status and changelog updates

risc-v-gsp-rm-debugger: land docs 45-53 + harness/sim tool set with tests

2026-10-06T23:28:39+00:00

rm_capture (chunked decode), launch_audit, state_seed/state_decode, valprobe, rehost, contracts+run_contracts, host_traffic, gmmu_walk, msgq_attach, libos_port, log_decode, server_snapshot; doc index updates in the tool overview, operations pages and the repo README.

greeneye: GMMU/FBIF observability, PTE decoder and oracle, MPU/libos simulator wave

2026-10-04T22:42:36+00:00

Simulator development wave (docs 42-44): GMMU page-table entry decode with its oracle/workflow harness, FBIF observability, and MPU/LIBOS device surfaces in the device model, plus refreshed boot/machine/profile data (tu104-570.144), the qemu-line results, and the new unit tests. Docs 00/06/35-41 updated to match; harness helpers and .gitignore included.

vgsp: host CUDA bridge + sema release recovery; greeneye simulator wave

2026-10-03T18:05:38+00:00

- kernel: gsp_cuda_bridge (QMD launch capture, debugfs job/out/done, param+output resolution cached from inline writes), sema drain fixes (never hold/starve a channel), GR ring autopin + counter autoreg, per-page push reads, counter-derive gate; module builds clean - tools/cuda-bridge: CUDA driver-API daemon executing mail/vadd kernels on the physical GPU, CUBB2/CBD2 v2 protocol, layout check + self-tests - tools/guest-diag + tools/cuda-ab: scanner/pin fixes, victory push-only mode - debug/risc-v-gsp-rm-vm: Phase S simulator wave (GSP device model, boot ladder, triage/re-demo harnesses, docs 30-41), GPGPU-sim scaffolding - STATE-CURRENT/docs updates

kernel: GR context-promote bisection modes 4-17 and server-managed-ctxbuf registry variant; complete vgsp rename; docs/tooling refresh

2026-10-02T19:13:06+00:00

- gsp_phys_booter: GR promote bisection modes 4-17 (two-phase zero-field VA, batched entries, hVirtMemory, bare VA, KMD SKIP_CTXBUFFER_ALLOC channel, old-interface GPU_INITIALIZE_CTX, FBMEM context buffer, UVM-faithful PA-only, PATCH/PM auxiliary promotes, server-managed no-promote path); PATCH/PM geometry queries and buffers; pre-boot SET_REGISTRY profile selection - gsp_phys_gpu: gsp_phys_rmcall_gr_promote clamp 0..17 and gsp_phys_srv_ctxbuf parameter; registry image variant with RMSetClientRMAllocatedCtxBuffer=0 - vgsp rename across kernel, scripts, tools and docs (module vgsp.ko, /sys/kernel/debug/vgsp/, vgsp-: log prefixes) - risc-v-gsp-rm-debugger user-facing rename and docs/CI refresh; guest-diag tool updates; README/SBOM/install/Makefile sync Live status: CE ladder and P6 guest-copy forwarding green; GR engine context commit still open (all promote shapes accepted or cleanly refused; the channel stays CTXNOTVALID) - see Handoff-vGPU-IO.md Addendum 21 (local).

debug: risc-v-gsp-rm-debugger final pass - remove in-development notices, complete rename, adversarial-review fixes

2026-10-02T16:41:52+00:00

Remove the '# TOOL IN DEVELOPMENT - NOT READY YET!' notices from the tool docs/README/scripts and the project docs; record the removal (2026-10-02) against the tool audit (debug/risc-v-gsp-rm-vm/docs/27-TOOL-AUDIT.md), the 194-test suite and the value-validation demos (docs/25-VALUE-VALIDATION.md). Complete the cosmetic rename to risc-v-gsp-rm-debugger in user-facing prose and commands (launcher, roadmap, docs); internal greeneye package and code identifiers unchanged. Adversarial-review fixes: deterministic control-discovery sweep (flaky test root-caused), UUID session dirs + atomic JSON writes for concurrent runs, Ghidra bridge loopback enforcement and clean shutdown, fp register restore in Session.call, version_diff --dry-run, 30 s interrupt budget, dry-run non-destructiveness verified. Docs: flag-removal records, link fixes, command/flag corrections (fdematch arity, port_new_device --out, trace filename), F2 orchestration note in future-eng-ops; STATE-CURRENT status refreshed.

rename (cosmetic): green-eye -> risc-v-gsp-rm-debugger in user-facing names, docs, CLI, launcher and CI workflow; internal greeneye package/module identifiers unchanged (includes in-flight greeneye module edits present in the tree)

2026-10-02T15:44:31+00:00

debug: green-eye porting automation - new-device and driver-version port scripts, simulator packaging, porting docs; control-discovery fix
