The plan is to pass requests around as the basic submission tracking structure rather than rings and contexts. This patch updates the i915_gem_object_sync() code path. v2: Much more complex patch to share a single request between the sync and the page flip. The _sync() function now supports lazy allocation of the request structure. That is, if one is passed in then that will be used. If one is not, then a request will be allocated and passed back out. Note that the _sync() code does not necessarily require a request. Thus one will only be created until certain situations. The reason the lazy allocation must be done within the _sync() code itself is because the decision to need one or not is not really something that code above can second guess (except in the case where one is definitely not required because no ring is passed in). The call chains above _sync() now support passing a request through which most callers passing in NULL and assuming that no request will be required (because they also pass in NULL for the ring and therefore can't be generating any ring code). The exeception is intel_crtc_page_flip() which now supports having a request returned from _sync(). If one is, then that request is shared by the page flip (if the page flip is of a type to need a request). If _sync() does not generate a request but the page flip does need one, then the page flip path will create its own request. v3: Updated comment description to be clearer about 'to_req' parameter (Tomas Elf review request). Rebased onto newer tree that significantly changed the synchronisation code. v4: Updated comments from review feedback (Tomas Elf) For: VIZ-5115 Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Reviewed-by: Tomas Elf <tomas.elf@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
