Unified shared memory allocation (shared memory allocation) in Intel Integrated Graphics

Hello,

I would like to ask regarding the support for unified shared memory mainly shared memory allocation using clSharedMemAllocINTEL API function in Intel Integrated Graphics.

 

The documentation in: cl_intel_unified_shared_memory   , clSharedMemAllocINTEL allocate shared memory between host and device which can be migrated between CPU (host) and GPU (device).  The resources I found so far mostly discuss shared memory allocation in case of discrete GPUs.

What is the situation in case of intel Integrated Graphics (gen9, gen11) when the CPU the integrated graphics (gen9 or gen11) use the same main memory. Is there migration in this case? or both the CPU and integrated graphics will use the same physical allocated shared memory.

 

Thanks,
