    drm/i915: turn bound_ggtt checks to bound_any · 9843877d
    Ben Widawsky 提交于
    In some places, we want to know if an object is bound in any address
    space, and not just the global GTT. This often applies when there is a
    single global resource (object, pages, etc.)
    
    function                             |      reason
    --------------------------------------------------
    i915_gem_object_is_inactive          | global object
    i915_gem_object_put_pages            | object's pages
    915_gem_object_unpin                 | global object
    i915_gem_execbuffer_unreserve_object | temporary until we plumb vma
    pread/pwrite                         | see the note below
    
    Note: set_to_gtt_domain in pwrite/pread is abused as a wait_rendering
    call - but that once only worked if the object is bound. We really
    should replace this with a plain wait_rendering call, which would have
    the upside that in pread it would be clearer that we actually only
    wait for oustanding gpu writes.
