| 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. |
