Description
If a SVM object is created and then `clCreateBuffer` is called with `CL_MEM_USE_HOST_PTR` on that SVM object, will all calls to `clEnqueueReadBuffer` act as `clEnqueueSVMMap` with `CL_MAP_READ`? And will `clEnqueueMapBuffer` act like `clEnqueueSVMMap` on the underlying SVM pointer?
EDIT:
Added clEnqueueMapBuffer
Contributor guide
Research direction
Start with the documented semantics of clCreateBuffer with CL_MEM_USE_HOST_PTR when the host pointer is an SVM allocation. Compare clEnqueueReadBuffer and clEnqueueMapBuffer with clEnqueueSVMMap, and finish by documenting a clear answer for both behaviors.
