Subject: Release Notes for Beignet Version 0.1
Beignet (Intel OpenCL Open Source Project) Version 0.1
Release Notes:
We are pleased to release the Beignet version 0.1.
Beignet is a project that provides OpenCL support for Intel platforms.
It includes an LLVM/Clang based OpenCL compiler and a runtime.
This version supports GPU type context on IVY Bridge(IVB) platform only.
New features in this release:
1. 2D image write(typed_write)/read(sampler).
2. Partial support of cl_khr_gl_sharing extension.
3. Cmake build fixup.
4. Add/Enable some OpenCL 1.0 APIs and built-in functions.
5. Various bug fixing.
6. More unit test cases.
For more detailed information, please check the source
code and read the documents.
