| + | **VIM3** has OpenCL capabilities for both NPU and GPU, and by default the OpenCL lib in /usr/lib is for NPU. | ||
| + | To use the GPU for proper acceleration follow the below steps to replace the correct library for the GPU. | ||
| + | ```shell | ||
| + | # Move the NPU OpenCL lib | ||
| + | $ sudo mv / | ||
| + | |||
| + | # Symlink the right OpenCL lib for Mali GPU | ||
| + | $ sudo ln -s / | ||
| + | ``` | ||
| + | |||
| + | Note: With the 4.9 kernel, there is only OpenCL 2.0 capability and PyOpenCL will break, migrating to 5.15 kernel images will resolve it. | ||
