To compile this driver as a module, choose M here: the module will
be called uv_sysfs.
-config INTEL_WMI_THUNDERBOLT
- tristate "Intel WMI thunderbolt force power driver"
- depends on ACPI_WMI
- help
- Say Y here if you want to be able to use the WMI interface on select
- systems to force the power control of Intel Thunderbolt controllers.
- This is useful for updating the firmware when devices are not plugged
- into the controller.
