* greeneye: GMMU/FBIF observability, PTE decoder and oracle, MPU/libos ↵Arthur Hanson Rasmusson8 days
| | | | | | simulator wave 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 waveArthur Hanson Rasmusson9 days
| | | | | | | | - 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 ↵Arthur Hanson Rasmusson10 days
| | | | | | | | | | | | | | | | | | | | registry variant; complete vgsp rename; docs/tooling refresh - 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-<subsystem>: 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, ↵Arthur Hanson Rasmusson10 days
| | | | | | | | | | | | complete rename, adversarial-review fixes 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, ↵Arthur Hanson Rasmusson10 days

* debug: add green-eye GSP/uproc RISC-V VM runtime analysis toolingArthur Hanson Rasmusson10 days
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.
