kernel: GR context-promote bisection modes 4-17 and server-managed-ctxbuf registry variant; complete vgsp rename; docs/tooling refresh
- 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-<subsystem>: 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).
