Unoffical Intel(R) Graphics Compute Runtime for oneAPI Level Zero and OpenCL(TM) Driver with limited support for OpenCL/OpenGL interoperability
The Intel(R) Graphics Compute Runtime for oneAPI Level Zero and OpenCL(TM) Driver is an open source project providing compute API support (Level Zero, OpenCL) for Intel graphics hardware architectures (HD Graphics, Xe). This repo is an unoffical fork with limited support for OpenCL/OpenGL interoperability
Only the first device in platform.
- EGL (GLX is not supported)
- GL_TEXTURE_2D target
- GL internal_formats: GL_RGBA, GL_RGBA8, GL_RGBA16F, GL_RGB
For more information on the offical project refer to: https://github.com/intel/compute-runtime/#readme
At the moment only Tigerlake (Gen11) is tested but it should work for all target CPUs (Gen8 - Gen12). Please provide feedback if it worked for you on another CPU than Tigerlake.
There are tarballs in every release that contain all the files needed. Please check if the paths comply with your Linux distribution.
