In linux kernel since version 6.13 (release Date: 2025-01-19)
Host System Management Port (HSMP) interface is a mailbox interface
between the x86 core and the System Management Unit (SMU) firmware.
The driver provides a way for user space tools to monitor and manage
system management functionality on EPYC and MI300A server CPUs
from AMD.
This option supports ACPI based probing.
You may enable this, if your platform BIOS provides an ACPI object
as described in amd_hsmp.rst document.
If you choose to compile this driver as a module the module will be
called hsmp_acpi.
