Build xrt-smi Utility on Windows

XRT Version: master, commit: 3ee37cfefc32047fea8d334164844e900ad8e7ef
Platform: Windows
Hello there,
I am trying to compile the xrt-smi tool on Windows, but I can't find any step-by-step guide on how to do this.
For context, I am exploring ways to diagnose the health of NPU devices. I discovered this tool in the NPU Management Interface — Ryzen AI Software 1.3 documentation. After installing the Ryzen AI tool, I was able to find and use the xrt-smi utility as expected.
However, I want to understand more deeply what happens during these tests and leverage the same API that the utility uses in my own application. When I attempted to compile the tool myself, I encountered an issue.
To be precise, I was able to compile the tool by using the build/build22.bat file, but the compiled version behaves differently from the one installed on my machine. Specifically, it does not detect my NPU device. I wonder if I need to configure a specific environment variable or define certain macros to achieve the same result as the installed version.
Could you provide guidance or documentation on how to properly build the xrt-smi tool on Windows? Also, if this is not the correct place to ask this type of question, please let me know.
Thank you in advance!
@a-carrara. Make sure the hash of https://github.com/Xilinx/XRT you pull to build xrt-smi corresponds to the hash listed by running xrt-smi examine on your system. xrt-smi must be in sync with driver and libraries installed on your system.
Let me know if you continue to run into problems.
@stsoe It Works! Also, to run with my versions of xrt_core.dll and xrt_coreutil.dll, I had to define the macro XRT_WINDOWS_HAS_WDK before compiling everything.
@a-carrara Good to hear it works for you.
Your own xrt_core.dll is not at all used by NPU, it is an Alveo library. For NPU, libxrt_core.dll is so far not even open source and the binary is loaded from the Windows driver store.
When you install the driver for NPU, xrt_coreutil.dll is installed in windows/system32/ folder and libxrt_core.dll in the driver store. xrt-smi (and any user application) uses xrt_coreutil.dll, which in turn loads libxrt_corel.dll at runtime.
When I advised you to make sure XRT was at the git hash reported by xrt-smi, it was because xrt-smi indirectly loads xrt_core from the driver store and the version of xrt_core must match the version of xrt_coreutil.
