docs(review): fix GMMU-doc anchors and vEP vocabulary; index docs 13/14 in the READMEs

2026-10-08T18:10:23+00:00

The GMMU doc cited pre-a9d29cba lines for the pump, doorbell and svc_sem_write, defined vEP differently from doc 13 (which it names as the vocabulary authority), and called Design A prototypable in the 1.0 programme while M6 classifies the same prototype as post-1.0 research. Fix all three, refresh the status hash, and add the doc to the docs/ and wiki/ indexes with the renumbered reading-order rows.

docs(vexecution-plane): add the vGSP Execution Plane architecture doc, wiki deep dive and indexes

2026-10-08T17:41:31+00:00

docs: add the GR compute-launch frontier page and align execution status across the tree

2026-10-06T19:18:39+00:00

New page docs/04-implementation/03-execution-frontier.md describes the chain that must fire for a guest CUDA launch (guest push -> GPFIFO/front-end -> inline launch-descriptor install -> engine read/dispatch -> completion), where the leading edge is (the descriptor install path), how we know (front-end vs engine-authored observables and their limits), what is exonerated (context validity at dispatch, destination window mapping, fetch alignment, shared-buffer rule, parenting), the ranked issues (verbatim prelude targets, missing descriptor-virtualization control, sentinel hygiene), live investigation lines and labelled theories. Align every page that still said GR execution is blocked on engine-context validity to the current frontier, and add the new page to the README reading order (row 15, later rows renumbered). Docs only; no code.

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

docs: engineering-operations playbook and project-wide status accuracy pass

2026-10-02T15:28:49+00:00

- docs/eng-ops.md gains Part II, live physical-backend engineering operations: hard rules, the full module-parameter matrix, the routine supervised cycle and clean-release checklist, the debugfs inventory, how to read gsp-phys-state, a debugging scenario catalogue (CTXNOTVALID/promote wedge, fail-safe WPR2, unload hangs, guest wedges, MMU/PTE and PBDMA faults, relay symptoms), a hazard register (crash causes and debugging side effects), the physical-backend OODA loop, and the work-context map with porting flows - architecture, implementation, operations, orientation, getting-started, portability, ecosystem and reference docs corrected to the current state: CUDA driver-API smoke green, CE-class work forwarding and engine-authored releases plus fault relay in place (default off), GR execution blocked on engine-context validity, the promote wedge and designed locked fail-safe, and P5 wave-2 subsumed - internal-reference cleanup in tracked docs (no analysis-source or local-archive references); historical architecture document bannered - README reading list and STATE-CURRENT frontier refreshed; new pages (runbook, green-eye user guide, porting sequence, porting/packaging notes) linked from the tree Link check: scripts/check-docs-links.py passes (56 files, no broken links).

debug: add green-eye GSP/uproc RISC-V VM runtime analysis tooling

2026-10-02T12:36:35+00:00

Adds open-iov/debug/risc-v-gsp-rm-vm: a GDB-free instrumentation stack that boots uproc/GSP firmware in qemu-system-riscv64 and provides Frida-like hooks, breakpoints, watchpoints, memory dumps, structure decoding, snapshot diffs, recorded sessions, declarative probes, a plugin API and a Ghidra symbol/hit bridge. Verified: 25 tests green (including a live QEMU smoke test); the demo uproc boots with correct hook/leave/watch/schema/snapshot/fault evidence; the optional TCG trace plugin builds and recorded 15M trace lines in 3 s; the TU104 570.144 fwimage probe reports its first exception (load access fault at firmware vaddr 0x4009014 reading 0x2000000000000A00). Documentation: lean tool docs under debug/risc-v-gsp-rm-vm/docs/00-10, a new docs/05-operations/03-risc-v-gsp-rm-vm.md debugging document, and '# TOOL IN DEVELOPMENT - NOT READY YET!' markers in docs/README.md, the onboarding tooling table and the debugging workflows doc. Vendors qemu-plugin.h from QEMU v8.2.2 (GPL-2.0-or-later), with its license header intact, so the optional TCG plugin builds without a QEMU source tree.

docs: record host VF acceleration as a deferred future goal

2026-10-02T02:15:15+00:00

STATE-CURRENT + docs: first real copy executed by the physical CE; add the physical-backend guest-wiring design

2026-10-02T00:58:32+00:00

- 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.
