The dell-wmi-ddv driver adds support for reading the current temperature and ePPID of ACPI batteries on supported Dell machines. Since the WMI interface used by this driver does not do any input validation and thus cannot be used for probing, the driver depends on the ACPI battery extension machanism to discover batteries. The driver also supports a debugfs interface for retrieving buffers containing fan and thermal sensor information. Since the meaing of the content of those buffers is currently unknown, the interface is meant for reverse-engineering and will likely be replaced with an hwmon interface once the meaning has been understood. The driver was tested on a Dell Inspiron 3505.
