What's the impact to drm_gralloc?
2018-04-20 5:09 GMT+08:00 Rob Herring <r...@kernel.org>:
> Maintaining both flink names and prime fd support which are provided by
> 2 different gralloc implementations is problematic because we have a
> dependency on a specific gralloc implementation header.
>
> This mostly removes the dependency on the gralloc implementation and
> headers. The dependency on GRALLOC_MODULE_PERFORM_GET_DRM_FD remains for
> now, but the definition is added locally to remove the header
> dependency.

> With this plus Robert's probing patch, we remove any gralloc
> implementation dependency (other than it has to be a pre 1.0
> implementation...).
