2.2. Agency

The agency is the whole software which is resident within a smart object. It is composed of the avz hypervisor and Linux as the main domain. Actually, the domain is divided in domain #0 which is the non realtime domain of the agency, and domain #1 which is a hard realtime domain running independently of the Linux scheduler. The hard realtime domain is a highly modified version of the Xenomai/Cobalt kernel with its RTDM API.

The figure below shows the Agency subsystems and functional blocks.
