This section includes the global registers used by system software to request several platform services.
  • Power up and down of domains and islands
  • Isolation of interfaces and signals between power domains
  • Reset of subsystems and power domains

The service requests are serviced by the PLM and PSM firmware. System software writes to the PMC and PSM global registers to request a service.
