[PATCH 00/22] drm/i915 & drm/xe: kill off -Ddrm_i915_gem_object=xe_bo

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

 



The xe Makefile defines -Ddrm_i915_gem_object=xe_bo to build i915
display for xe. This lengthy series removes that hack.

This is based on two ideas:

1) Always use struct drm_gem_object instead of struct
   drm_i915_gem_object or xe_bo in code that gets built for both i915
   and xe.

2) Add intel_bo_*() abstraction functions for things that need i915 and
   xe specific implementations. There's one shared intel_bo.h in i915
   display, and separate intel_bo.c in i915 and xe. Also these functions
   operate on struct drm_gem_object.

The rest is just gradual conversion and cleanup.

There'll still be some code remaining in i915 display that gets only
built for i915, and continues to use struct drm_i915_gem_object. Maybe
we'll want to continue the conversion with them too.

The most important end result is that there's no longer confusion what
struct drm_i915_gem_object actually means. It means just that, you can't
accidentally use it in xe code, and it's never xe_bo anymore.


BR,
Jani.
