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.
