[RFC PATCH 18/20] drm/i915/display: Remaining changes to make xe compile

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Maarten Lankhorst <maarten.lankhorst@xxxxxxxxxxxxxxx>

Xe, the new Intel GPU driver, will re-use the i915 display.

At least for now, the plan is to use symbolic links and
adjust the build so we are building the display either for
i915 or for xe.

The display can be split out if needed.
Also the compilation is optional at this time

[Rodrigo changed i915_reg_defs.h, commit msg, and rebased]
