<content type='text'>
Password auth with key auth disabled outright: the host's id_rsa is
passphrase-protected and a stale copy of its public key in the guest's
authorized_keys made plain ssh hang on the passphrase prompt (the
reported 'sshpass hangs'). Wrapper defaults to 127.0.0.1:2222
ubuntu/ubuntu, overridable via VGPU_GUEST_*.

Sweep of the 155 tracked C/Python/shell files under userspace/ (excluding
the MIT-licensed vendored userspace/extern/), tools/ and scripts/ that had
no per-file license identifier. Each gains the minimal two-line header in
the area's existing form: 'SPDX-License-Identifier: BSD-3-Clause' plus
'Copyright (c) 2026 Open-IOV contributors'; shebang and coding lines stay
first. No other content touched. kernel/** is deliberately out of scope
(recorded as a follow-up in CODESTD-REPORT-2026-10-08.md): its SPDX
coverage and MODULE_LICENSE normalization need their own GPL-2.0 pass.

- 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-&lt;subsystem&gt;: 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).

<title>tools: durable guest counter enumeration/injection and VA reader</title>

<id>urn:sha1:6e04a93838cdebbcf9183278cb71bdf1b4235cdc</id>
<content type='text'>
The counter enumeration/injection workflow lived in the guest's /tmp and was
lost on every restart. Make it durable under tools/guest-diag:

- sem_counters.py: translate a process's per-channel u32 completion counters
  (16-byte stride in the /dev/nvidiactl counter page) to guest PAs through
  /proc/&lt;pid&gt;/pagemap; --pairs emits handle,va,pa triples.
- sem_slots.py: read/write the counter slots via /proc/&lt;pid&gt;/mem (fallback
  for the host counter publish).
- read_va.py: hex dump a process VA (UVM sysmem GPU VAs are usually valid
  CPU VAs in the owning process); --u32 for method streams.
- inject_counters.sh: host-side one-shot: push the tool, take the GR handles
  from the live chan_dump, enumerate, then register each counter with
  sema_counter and pin its VA with sema_map_add.
- push_guest_tools.sh: push the new tools after every VM start.
- launch_qemu_direct.sh: parameterized mdev UUID/paths instead of a stale
  hardcoded one; committed so it survives checkouts.

<content type='text'>
- admit {GPU VA -&gt; PA} pairs only when the preceding bytes form a valid
  client memory descriptor header (type 0/1, CPU+GPU mapped bits), prefer
  validated pairs over headerless candidates under first-wins dedup, and
  invalidate the translation cache on every rebuild; fixes stale identity
  entries shadowing live pool pages and lets the guest UVM channel
  bring-up complete on its own
- capture OS event allocations (class 0x79) and post event records
  (function 0x1003) into the guest status queue when a channel's busy
  notification is consumed, with a broadcast fallback, serialized with
  replies via a queue lock
- add BAR0 shadow introspection (dump_bar0/scan_bar0) and guest-side
  diagnostic scripts for the VM cycle

<title>docs: merge the legacy flat documents, add the CUDA deep-dive and link checks</title>

<id>urn:sha1:fade84f8b5b781d29daad40699d07928dedea550</id>
<content type='text'>
* 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.
