/**
* struct drm_i915_gem_set_domain - Adjust the objects write or read domain, in
* preparation for accessing the pages via some CPU domain.
*
* Specifying a new write or read domain will flush the object out of the
* previous domain(if required), before then updating the objects domain
* tracking with the new domain.
*
* Note this might involve waiting for the object first if it is still active on
* the GPU.
*
* Supported values for @read_domains and @write_domain:
*
* - I915_GEM_DOMAIN_WC: Uncached write-combined domain
* - I915_GEM_DOMAIN_CPU: CPU cache domain
* - I915_GEM_DOMAIN_GTT: Mappable aperture domain
*
* All other domains are rejected.
