  13 description: |
  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.
