2.2.5 Redistributor miscellaneous input signals
The Redistributor receives signals that identify the status of each core. It also has a tie-off signal that provides the Redistributor with a unique identifier.
2-8 Redistributor miscellaneous input signals
||This signal indicates if the core is active and not in a low-power
state such as retention. The GIC can decide to target only active cores for 1 of N
SPIs. See 3.15 Performance Monitoring Unit.
Note: cpu_active is not synchronized into the Redistributor. If cpu_active is driven from a
different domain, it must be synchronized externally.
||This tie-off signal provides the Redistributor with a unique
identifier that is used primarily to ensure that the GIC is correctly integrated into
