The Nvidia Hook
Total visibility into the black box of GPU compute. Microsecond intercept on every CUDA launch and every ioctl.
The Hook attaches below the agent — in the host kernel — via a Rust eBPF runtime. A uprobe on libcuda.so:cudaLaunchKernel records every GPU launch. The syscalls:sys_enter_ioctl tracepoint records every driver-bound ioctl. The agent doesn't see us. The driver doesn't see us. We see everything.
