NVIDIA display mux #1024

Open mkopec opened 3 weeks ago

The problem you're addressing (if any)

NovaCustom V5x0TNx have "Advanced Optimus" - a mux for internal panel. Currently we do not support this in Dasharo.

Describe the solution you'd like

Add support for the display mux. This includes setting the flag in NVIDIA ASL code to identify to the driver that the internal display is muxed. It may also be required to handle display brightness in EC, since it's supposed to drive the brightness PWM signal when in DDS mode.

Where is the value to a user, and who might that user be?

Improved GPU performance

Describe alternatives you've considered

none
