Each OPP has a specific frequency/power consumption/performance. On Device Tree (DT) based platforms, the SCMI protocol is directly available from the OS. On ACPI based platforms, the _PSD objects allows to identify CPUs belonging to the same performance domain. CPUs belonging to the same performance domain have the same frequency. The _CPC object allows to describe/control the performance level/frequency of a CPU (i.e. its frequency). This patchset: - Add support for 'DescribeFastchannel' SCMI performance protocol - Add a object to the DynamicTablesPkg to describe the PSD information - Allows to generate _PSD objects in the SsdtCpuTopologyGenerator - Add a ArmScmiInfoLib library populating DynamicTablesPkg CPC objects, relying on the SCMI protocol to fetch the relevant information A patchset for Juno-r2 platforms will be submitted to demonstrate this functionality.
