spdx: add BSD-3-Clause identifiers to userspace/tools/scripts sources

2026-10-08T15:53:20+00:00

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.

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).

guest-diag: ctx999.py (scanner/ctx gdb capture); fix pinner exact-VA match

2026-09-28T17:27:31+00:00

ctx999.py arms the scanner entry/returns plus cuCtxCreate and dumps the ctx->mgr->reg->record chain at the stop. First live capture: the scanner is called with param_2=1 during normal context creation and correctly returns 0 on a zero record (mgr[+0], the channel handle, and the record walk are now confirmed live). pin_miss_pages.sh must match the exact VA pmapall printed: guest_pmap_all.py returns the first nvidia page at-or-above va-min, so a page that is not present resolves to an unrelated mapping (it pinned a UVM page for 0x20400f000).

guest-diag: adaptive miss-driven pinner; cdt holds on failure for inspection

2026-09-28T17:14:16+00:00

pin_miss_pages.sh watches the host journal for release-miss VAs, resolves each page for the live cdt pid through the guest pagemap and injects it (the injection rewinds the pump so releases consumed under a stale pin are re-read); it re-pins when a new cdt pid appears. cuda_drv_test prints cuGetErrorName/String on failure and, with CDT_HOLD=, stays alive so the RM error record and tracker state can be inspected after cuCtxCreate has given up.
