I guess that the two semantically relevant errors here would be:
HSA_EXT_POINTER_TYPE_UNKNOWN
and
HSA_STATUS_ERROR_INVALID_ARGUMENT (which we should never get because we already
checked whether ptr is null). The rest of the errors "out of resources, hsa not
initialized" would have been caught earlier on, is my guess
