# SPDX-License-Identifier: GPL-2.0-only # # AMD x86 Platform Specific Drivers # config AMD_PMC tristate "AMD SoC PMC driver" depends on ACPI && PCI && RTC_CLASS help 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. config AMD_HSMP tristate "AMD HSMP Driver" depends on AMD_NB && X86_64 help The driver provides a way for user space tools to monitor and manage system management functionality on EPYC server CPUs from AMD. Host System Management Port (HSMP) interface is a mailbox interface between the x86 core and the System Management Unit (SMU) firmware. If you choose to compile this driver as a module the module will be called amd_hsmp.
