Analysis tooling for debugging CUDA execution in Open-IOV guests:
- userspace/cuda/570.144/: fetch a library from a running guest (nc),
objdump helpers, crash ip -> file vaddr + symbol mapping, and Ghidra
headless import/analysis/decompile scripts (project kept so single
functions decompile in seconds). The purpose is debugging correctness
and performance of CUDA in Open-IOV VMs (not a reimplementation);
extracted binaries and decompiled output are gitignored.
- tools/guest-diag/ioctl_trace.c: ptrace tracker for the NVIDIA driver
ioctls of a child (libcuda issues raw syscalls, so LD_PRELOAD sees
nothing). Decodes RM_ALLOC (class) and RM_CONTROL (cmd) arguments;
this is how the cuCtxCreate crash sequence was captured.
- tools/test/cuda_drv_test.c: unbuffered + per-call markers so a crash
identifies the CUDA call it happened in.
