0013 description:
0014 RPMh interconnect providers support system bandwidth requirements through
0015 RPMh hardware accelerators known as Bus Clock Manager (BCM). The provider is
0016 able to communicate with the BCM through the Resource State Coordinator (RSC)
0017 associated with each execution environment. Provider nodes must point to at
0018 least one RPMh device child node pertaining to their RSC and each provider
0019 can map to multiple RPMh resources.
