From c8ccdd772c7650f19d14f143f34b700813575746 Mon Sep 17 00:00:00 2001 From: Arthur Hanson Rasmusson Date: Thu, 8 Oct 2026 04:15:24 -0400 Subject: vgsp+guest-diag: kcore-truth pin resolver (pool/pushbuffer/channel ring+userd) + GR ring userd-derived candidates guest_pin_stream.py now resolves translations entirely from guest truth via /proc/kcore + a manual page-table walk (no QMP races): the CE semaphore pool and pushbuffer memory from the UVM rm_mem structures, and each channel's GPFIFO ring + GPPUT from the tracking semaphore's embedding uvm_channel_t (channel_info located by its gpFifoGpuVa value). This removes the watcher pipeline's flakiness on the cudaMalloc stall class (missing pool/pushbuffer pins). gsp_sema_service.c: svc_gr_ring_autopin tries the guest-registered USERD memdesc base as a ring candidate (the fixed FB convention only matches when the guest's VRAM allocator happens to reproduce the old layout), plus an optional (gsp_sema_dbg) one-shot FB scan + raw-word diagnostics when every candidate fails. tools/cuda-ab/p2: self-checking arbitrary-kernel acceptance suite (10 programs: sequential launches, shapes, params, smem/GEMM, streams, malloc churn, printf+error, FMA benchmark, mixed, managed probe) with host oracle expectations and a guest runner. --- tools/cuda-ab/p2/expected/p2_params.txt | 2 ++ 1 file changed, 2 insertions(+) create mode 100644 tools/cuda-ab/p2/expected/p2_params.txt (limited to 'tools/cuda-ab/p2/expected/p2_params.txt') diff --git a/tools/cuda-ab/p2/expected/p2_params.txt b/tools/cuda-ab/p2/expected/p2_params.txt new file mode 100644 index 0000000..7833c07 --- /dev/null +++ b/tools/cuda-ab/p2/expected/p2_params.txt @@ -0,0 +1,2 @@ +RESULT params kernels=13 nparam_max=12 bad=0 checksum=395 +STATUS OK -- cgit v1.2.3
