xdna-top: unified NPU+iGPU terminal monitor for Strix Halo (Ryzen AI Max) — finally see the NPU work

If you're running local models on a Ryzen AI Max / Strix Halo box, you've probably noticed it's hard to see what the NPU is actuallydoing. amd-smi is still broken on

gfx1151 (ROCm #6035 (https://github.com/ROCm/ROCm/issues/6035)),

and while GNOME Resources has a GUI view, I haven’t found another terminal monitor that shows XDNA activity on this platform. nvtop / amdgpu_top cover the GPU half at best.

xdna-top shows both engines in one TUI at 5 Hz: iGPU busy/power from sysfs, plus per-context NPU submission/completion counters from xrt-smi, with activity derived from counter deltas. Important disclaimer up front: it does not print a made-up NPU “utilization %”. On this hardware, the honest signal is the counter activity, so that’s what it shows.

There’s also a --json mode if you want to log it nextto your throughput numbers.

Watching the NPU light up while the iGPU sits idle, or seeing both run concurrently, is weirdly satisfying.
