This has led to quite a bit of confusion with users not understanding why the LED color indicating the platform profile doesn't match their expectations. To solve this, replace the confusing convention by using the new max-power profile to represent "extreme mode". While add it, update the documentation to reflect the expected LED colors in each operating mode. Signed-off-by: Derek J.

This prevents the WMI driver core from matching said driver to its WMI device. Fix this by turning the lowercase character into a uppercase character. Also update the WMI driver development guide to warn about this.

The driver uses a ACPI interface to talk with the embedded controller, but relies on a ACPI WMI interface for receiving event notifications. The driver is reverse-engineered based on the following information: - OEM software from intel - https://github.com/pobrn/qc71_laptop - https://gitlab.com/tuxedocomputers/development/packages/tuxedo-drivers - https://github.com/tuxedocomputers/tuxedo-control-center The underlying EC supports various features, including hwmon sensors, battery charge limiting, a RGB lightbar and keyboard-related controls.

The battery matchign algorithm is necessary when translating between ACPI batteries and the associated indices used by the WMI interface based on the battery serial number. Since this serial number can only be retrieved when the battery is present we cannot perform the initial translation inside dell_wmi_ddv_add_battery() because the ACPI battery might be absent at this point in time. Introduce dell_wmi_ddv_battery_translate() which implements the battery matching algorithm and replaces dell_wmi_ddv_battery_index(). Also implement a translation cache for caching previous translations between ACPI batteries and indices. This is necessary because performing a translation can be very expensive.
