Detailed Description

Object descriptor.

Must be first element of any objects descriptors placed in shared memory

Make sure this structure is multiple of 64b

Field Documentation

host_port_id

volatile uint16_t tivx_obj_desc_t::host_port_id[TIVX_OBJ_DESC_MAX_HOST_PORT_ID_CPU]

holds the index of the IPC port on OpenVX host for this object descriptor for each remote CPU

A connection to each remote CPU could be on a different host_port_id, hence this needs to hold host_port_id for each remote CPU, this array is indexed by TIOVX CPU ID. TIVX_OBJ_DESC_MAX_HOST_PORT_ID_CPU MUST be <= TIVX_CPU_ID_MAX
