RPMh 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. |
