JetPack 7 / Thor Support

This fork builds on JetPack 7.x (L4T r38/r39, CUDA 13) for Jetson Thor T5000/T4000 and Jetson Orin, verified against JetPack 7.2 (CUDA 13.2.1 / TensorRT 10 / Ubuntu 24.04 / Python 3.12):

• On CUDA 13 the CUDA kernels are compiled for sm_87 (Orin) and sm_110 (Thor), and the library is built as C++17 (CUDA 13 dropped compilation for architectures below sm_75).
• NVMM zero-copy memory remains disabled on JetPack 6 and newer (nvbuf_utils was removed from L4T) - video streams flow through system memory instead.
• JetPack 4/5/6 builds are unchanged.

Building from Source (C++/CUDA)

This will build and install the C++/CUDA library (libjetson-utils.so) along with the Python extension module:

git clone https://github.com/dusty-nv/jetson-utils
cd jetson-utils
mkdir build
cd build
cmake ../
make -j$(nproc)
sudo make install
sudo ldconfig

If you're missing dependencies, run the jetson-inference/CMakePreBuild.sh script.

Install with Pip (Python only)

This will install the Python-native modules from python/jetson_utils which do not depend on the C++ extension bindings and get installed on top:

pip3 install -e /path/to/your/jetson-utils

Or directly from GitHub:

pip3 install git+https://github.com/dusty-nv/jetson-utils
