PMF core layer is meant to abstract the common functionalities across PMF features. This layer also does the plumbing work like setting up the mailbox channel for the communication between the PMF driver and the PMFW (Power Management Firmware) running on the SMU.

The driver provides support for AMD Power Management Controller
|
|
primarily responsible for S2Idle transactions that are driven from
|
|
a platform firmware running on SMU. This driver also provides a debug
|
|
mechanism to investigate the S2Idle transactions and failures.

Say Y or M here if you have a notebook powered by AMD RYZEN CPU/APU.

If you choose to compile this driver as a module the module will be
|
|
called amd-pmc.

Host System Management Port (HSMP) interface is a mailbox interface
|

between the x86 core and the System Management Unit (SMU) firmware.
