- 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).
sema-svc: apply releases promptly and decode compute-push releases2026-09-28T11:34:34+00:00Arthur Hanson Rasmussonarthur@vgpu.io2026-09-28T11:34:34+00:00urn:sha1:2133dd1fd82b4fd37df45e134b9a073f081d49d1
The content sweep now:
- decodes a release whose method stream continues with any INC_METHOD,
not only the CE LAUNCH_DMA group, so the releases at the head of a
compute/GR channel's first push are applied too;
- remembers releases whose target VA had no translation (deferred list)
and retries them every service pass, so a VA->PA injection lands them
immediately instead of after the next full sweep;
- re-arms the fast sliced sweep for a few seconds after an injection;
- treats a channel whose USERD/ring cannot be resolved as stalled, so the
sweep keeps looking for the releases its unreadable pushes carry.
tools: add per-cdt client-pin helper (sem pages + /dev/nvidia0 windows),
sem-page scanner and memprobe fixes (short-read guard, --brief).
Live-verified: injecting a client sem page applied 12 deferred releases
within a second; the service kept applying (89 -> 202) while cdt ran.
