14   RPMh interconnect providers support system bandwidth requirements through
15   RPMh hardware accelerators known as Bus Clock Manager (BCM). The provider is
16   able to communicate with the BCM through the Resource State Coordinator (RSC)
17   associated with each execution environment. Provider nodes must point to at
18   least one RPMh device child node pertaining to their RSC and each provider
19   can map to multiple RPMh resources.
