Hi, everyone

I'm new to qualcomm OpenCL implementation. I want to know somthing before diving into

  1. Does qualcomm's OpenCL implementation support  C++ kernel like cuda, for example template  and class?
  2. Can we include extra header in .cl kernel file?
  3. Can we call memory allocating function in kernel, for example clSVMAllocate?

Thanks.

Here are the answers: 

  1. We do not support OpenCL C++ kernel language at this time. This is a feature in OpenCL 2.2 standard. Currently we support OpenCL 2.0. 
  2. Yes, you can include header in OpenCL kernel files. 
  3. Yes, Adreno has supported coarse grain shared virtual memory since A5x. You can use clSVMAlloc at host side to allocate memory that is going to be shared between device and host. But this function is not to be used inside kernels. 

Thank you.

Thanks for you answers.

Do you know when the support to OpenCL 2.2 is available on Qualcomm  platform?

At this time we don't have plan to support it.
