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).

kernel: validate learned semaphore maps and post guest GPU events

2026-09-24T05:58:15+00:00

- admit {GPU VA -> 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
