Abstract
A data processing system supporting a secure domain and a non-secure domain comprises a hardware component, and a processor device having operating modes in the secure domain and non-secure domain, the processor device to execute a secure application in the secure domain. The hardware component has a property having a secure state. The property of the hardware component in the secure state may only be reconfigured responsive to instructions received from the secure domain. The secure application is operative to implement a configuration service to configure the property of the hardware component in the secure state, responsive to a request received from the non-secure domain according to an application programming interface associated with the secure application.
