Mapping External Memory to Host Allocation

Accelerator devices can map external memory as a host allocation. The ze_external_memmap_sysmem_ext_desc_t struct defines the system memory being mapped as part of the zeMemAllocHost. The user may use this extention to specify, as part of the pNext member of the ze_host_mem_alloc_desc_t , the system memory that needs to be mapped as part of the allocation being created with a call to zeMemAllocHost.
