Hello everyone!
I would like to ask, where to read about the mechanisms, lying underneath the migration of memory objects from and to device. I would like to receive a detailed explanation for any kind of OpenCL implementation ( Intel is ok) what is happening during the buffers migration process(clEnqueueMigrateMemObjects function) (as well as enqueuing read (clEnqueueReadBuffer) and write buffers): maybe some caching is used, maybe some additional buffers, maybe dma, what calls are used to transfer the data over PCIe lanes - all such kind of details.
