docs: draw the physical-backend lifecycle (init, work, completion, teardown) on one page

2026-10-06T00:08:06+00:00

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).

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).

docs: refresh status wording after the 64/64 baseline and the physical-backend lock

docs: add the full-system picture and interaction/scheduling diagrams

2026-09-29T20:11:28+00:00

- new 03-architecture/09-full-system-picture.md: end-state map, GSP boot, guest init, RPC lifecycle, memory model, work path (bridge and end state), scheduling, isolation levels, KVM/mdev/VFIO, BAR/engine/channel/GMMU, portability, performance model, implementation/test status - new 03-architecture/10-interaction-and-scheduling.md: interaction inventory, control-plane call path, msgq element lifecycle, channel pump, concurrency, timing budgets, multi-tenant scheduling, teardown ordering, versioning - README: mermaid system diagram replaces the ASCII block; reading list extended and renumbered - component docs: GSP boot sequence, mdev/VFIO lifecycle, end-state interaction sequence; STATE-CURRENT links
