When CONFIG_HWMON is built as a loadable module, the HSMP drivers
cannot be built-in:
ERROR: modpost: "hsmp_create_sensor" [drivers/platform/x86/amd/hsmp/amd_hsmp.ko] undefined!
ERROR: modpost: "hsmp_create_sensor" [drivers/platform/x86/amd/hsmp/hsmp_acpi.ko] undefined!
Enforce that through the usual Kconfig dependnecy trick.
Fixes: 92c025db52 ("platform/x86/amd/hsmp: Report power via hwmon sensors")

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.
