The Wake Request block converts AXI4-Stream wake requests into one wake_request wire for each core. Each wake_request connects to the system power controller.
The following figure shows the Wake Request block.
The level of the asserted wake_request signal drops only when the Distributor leaves reset, or when the core is woken and the GICR_WAKER.ProcessorSleep bit is cleared to indicate that it is able to communicate with the GIC. The GIC supports a wake_request block reset only when the Distributor is also reset.
