These changes introduce compatibility with eDP displays and theoretically introduce compatibility with regular DP displays as well.

They also include

  • Refactoring of code that allows for functions specific to a model and or connection type
  • An update on the build documentation
  • Panel Power / Backlight implementations
  • A collection of scripts to assist in building/testing
  • A set of new structures that will decrease the number of parameters needed
  • Possible ability to support different generations of CPU/GPU

Known issues:

  • There is no display probing included. The connection type and DDI are hard coded.

Other Possible issues:

  • Most of the display port code is copied/ported from the linux i915 driver. Proper Attribution will be needed.

Note, There are still build warnings and other small issues that should be fixed before merging
