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.
