-description: |
- SC7180 interconnect providers support system bandwidth requirements through
- RPMh hardware accelerators known as Bus Clock Manager (BCM). The provider is
- able to communicate with the BCM through the Resource State Coordinator (RSC)
- associated with each execution environment. Provider nodes must point to at
- least one RPMh device child node pertaining to their RSC and each provider
- can map to multiple RPMh resources.
