[Beignet] clCreateFromGLTexture working?

[Pan, Xiuli]

Hi Sean,

It seems we do not support API clCreateFromGLTexture in beignet, you can get what api we support from the file src/cl_khr_icd.c.
If PyOpenCL can run into this maybe there is something wrong with the device extension check either for them or for beignet. I will recheck about this and give you a clear reply then.

Thanks
Xiuli

I'm getting a segfault with the following stack when trying to call clCreateFromGLTexture from PyOpenCL (which just got preliminary support for it):

Should this work with current Beignet master?
