The current blocker is the missing async copy engine in +> the emulated engine list (`cuCtxCreate` returns `999`). For the corrected, +> current analysis see +> [`../../docs/05-570.144-decompilation.md`](../../docs/05-570.144-decompilation.md) +> and [`../../READ-ME-FIRST.md`](../../READ-ME-FIRST.md). The runtime +> observations below (gdb traces, ioctl sequences) remain valid, and note that +> the decompiled files it references were produced at the wrong Ghidra image +> base (see PART 9's own address note and `../../docs/05` section 1.1). + + First analysis note for the CUDA userspace driver under Open-IOV. Companion to `../README.md` (tools) and the host/guest A/B harness (`tools/cuda-ab/`). |
