WebbThe purpose of registering pageable memory is to ensure that the data can be accessed and modified from the GPU. Registered memory is treated as hipHostMallocCoherent pinned memory, with equivalent performance.

WebbDevelopers are strongly encouraged to register memory blocks which are aligned to the host cache-line size. (typically 64-bytes but can be obtains from the CPUID instruction). If registering non-aligned pointers, the application must take care when register pointers from the same cache line on different devices. http://rtd13.readthedocs.io/en/latest/HIP-API.html

Default behaviour is allocation not mapped. If set, the pointer returned by mmap function will be host side memory mapped on device. A pointer to device memory can then be retrieved by calling hipHostGetDevicePointer(). If AML_AREA_HIP_FLAG_ALLOC_HOST is set, then host side memory will be allocated.
