Fix all three, refresh the status hash, and add the doc to the docs/ and wiki/ indexes with the renumbered reading-order rows. 2026-10-08T18:10:21+00:00 Arthur Hanson Rasmusson arthur@vgpu.io 2026-10-08T18:10:21+00:00 urn:sha1:92e45de48d2465594d4619be11b28581020e9eea Line anchors drifted when c33f6006 landed after the doc was written at d0213b5a (svc_thread, svc_gr_request, svc_pending_add, the H3 guard, the readiness gate). Also: the grv5 SEMA_DBG=Y campaign showed the notifier and event wake-up do fire while the counter slot publication is the link that never writes, so the document's 'completion wake-up' framing was stale in the stage table, section 3.4, section 6.1, the challenges and the iteration plan; refresh the status hash, the discovery-cadence wording and the mode-matrix source note, and extend the change log. 2026-10-08T18:04:47+00:00 Arthur Hanson Rasmusson arthur@vgpu.io 2026-10-08T18:04:47+00:00 urn:sha1:408f43802c13f1f6aff125d0acb25034fc1f5f73 2026-10-08T17:51:22+00:00 Arthur Hanson Rasmusson arthur@vgpu.io 2026-10-08T17:51:22+00:00 urn:sha1:d4d24b038b13c401b20ae9461f117819bb2f1784 2026-10-08T17:41:31+00:00 Arthur Hanson Rasmusson arthur@vgpu.io 2026-10-08T17:41:31+00:00 urn:sha1:9d1e0cf87df63a2f81c7bb471481336384874861 2026-10-02T06:50:38+00:00 Arthur Hanson Rasmusson arthur@vgpu.io 2026-10-02T06:50:38+00:00 urn:sha1:0054d3acbc3017d2a535239f8153d3c99f7abc18 2026-09-23T17:48:07+00:00 Arthur Hanson Rasmusson arthur@vgpu.io 2026-09-23T17:48:07+00:00 urn:sha1:fade84f8b5b781d29daad40699d07928dedea550 * Merge and remove the pre-reboot flat documents, preserving their still-useful material in the structured tree: debugging workflows and the EPT-livelock case study (05-operations/02), performance microbenchmarks and A/B methodology (05-operations/01), the version-upgrade runbook (05-operations/02 section 4, with corrected host/guest framing), kernel-code pitfalls (07-developers) and the OpenRM build/load order (03-architecture/06 section 7). The remaining legacy files were verified redundant and removed. * docs/README now records where each migrated topic lives. * Portability: the config YAML files are called out as design targets that no code reads yet, with what adding support actually requires today. * Getting started: the OpenRM step is marked optional (native vGPU-management workflows only; the emulated path uses the distro driver). * tools docs: rmtool/rmtop marked as planned, pointing at the implemented tools/rmq subset. * wiki: new CUDA-Userspace-Driver deep-dive page (public-safe, links the canonical userspace/cuda analysis) and index update. * scripts/check-docs-links.py plus a CI step so relative links cannot rot. * STATE.md references to removed documents repointed. 2026-09-23T16:11:10+00:00 Arthur Hanson Rasmusson arthur@vgpu.io 2026-09-23T16:11:10+00:00 urn:sha1:13f46e60760cc0855484cc69de913ea34f55c24f * Status now matches the live state: guest driver probe and nvidia-smi work; cuInit/device queries work; cuCtxCreate returns 999 because the emulated engine list is missing the async copy engine (COPY14). The userspace libcuda segfault is recorded as solved, with its mechanism (an RM allocation reply must echo request parameters; zeroing them corrupted the caller's saved frame pointer). * Correct the emulation claims: only a subset of RM controls are special-cased; the rest return a success reply with zeroed parameters whose consumed fields are still being corrected; allocation replies are coherent but no server-side object model exists. * Add the eight-point emulation checklist and reply-fidelity ladder as explicit gates, documented in userspace/cuda and linked from the architecture, implementation and operations docs. * Fix operational errors: build/test commands, module load order, mdev type names, LFS references, debugfs claims, in-repo firmware claims, CI claims, portability matrix (guest status, config layout, userspace driver facts). * Mark historical material: one superseded banner per legacy document with a pointer to its replacement; STATE.md marked as a 2026-09-21 snapshot. * Wiki: fix the index, add status banners and in-place factual corrections (msgq transport vs legacy mailbox, BAR definitions, error statuses, migration, glossary), and note the archived 2023 imports.
