Hello,
I need a list of the OpenCL extensions supported by Adreno GPUs. The best information I could find is here: https://developer.qualcomm.com/comment/6121#comment-6121
That information is a bit old, is that list still correct or have some new extensions been added, such as cl_khr_egl_image?
Thanks.

The extensions are documented in 80-N8592-1_L_OpenCL_Programming_Guide.pdf starting on page 9
That document did indeed answer my question, thanks.
But it is a little ambiguous about cl_khr_egl_image. That extension is not in the list on pages 9 and 10, but page 18 heavily implies that it is supported. So is it?
Yes it is.
I wrote an OpenCL demo sometime last year and one of the things I do is print out the list of supported extensions:

Here is a snippet you can use in your code:
