description:
|
|
RPM is a dedicated hardware engine for managing shared SoC resources,
|
|
which includes buses, clocks, power rails, etc. The goal of RPM is
|
|
to achieve the maximum power savings while satisfying the SoC's
|
|
operational and performance requirements. RPM accepts resource
|
|
requests from multiple RPM masters. It arbitrates and aggregates
|
|
the requests, and configures the shared resources. The RPM masters
|
|
are the application processor, the modem processor, as well as hardware
|
|
accelerators. The RPM driver communicates with the hardware engine using
|
|
SMD.
