/*
* CreateMsgCallback is global and needs to be
* applied to all layers and ICDs.
* What happens if a layer is enabled on both the instance chain
* as well as the device chain and a call to CreateMsgCallback is made?
* Do we need to make sure that each layer / driver only gets called once?
* Should a layer implementing support for CreateMsgCallback only be allowed (?)
* to live on one chain? Or maybe make it the application's responsibility.
* If the app enables DRAW_STATE on at both CreateInstance time and CreateDevice
* time, CreateMsgCallback will call the DRAW_STATE layer twice. Once via
* the instance chain and once via the device chain.
* The loader should only return the DEBUG_REPORT extension as supported
* for the GetGlobalExtensionSupport call. That should help eliminate one
* duplication.
* Since the instance chain requires us iterating over the available ICDs
* and each ICD will have it's own unique MsgCallback object we need to
* track those objects to give back the right one.
* This also implies that the loader has to intercept vkDestroyObject and
* if the extension is enabled and the object type is a MsgCallback then
* we must translate the object into the proper ICD specific ones.
* DestroyObject works on a device chain. Should not be what's destroying
* the MsgCallback object. That needs to be an instance thing. So, since
* we used an instance to create it, we need a custom Destroy that also
* takes an instance. That way we can iterate over the ICDs properly.
* Example use:
* CreateInstance: DEBUG_REPORT
* Loader will create instance chain with enabled extensions.
* TODO: Should validation layers be enabled here? If not, they will not be in
* the instance chain.
* fn = GetProcAddr(INSTANCE, "vkCreateMsgCallback") -> point to loader's
* vkCreateMsgCallback
* App creates a callback object: fn(..., &MsgCallbackObject1)
* Have only established the instance chain so far. Loader will call the
* instance chain.
* Each layer in the instance chain will call down to the next layer,
* terminating with
* the CreateMsgCallback loader terminator function that creates the actual
* MsgCallbackObject1 object.
* The loader CreateMsgCallback terminator will iterate over the ICDs.
* Calling each ICD that supports vkCreateMsgCallback and collect answers in
* icd_msg_callback_map here.
* As result is sent back up the chain each layer has opportunity to record the
* callback operation and
* appropriate MsgCallback object.
* ...
* Any reports matching the flags set in MsgCallbackObject1 will generate the
* defined callback behavior
* in the layer / ICD that initiated that report.
* ...
* CreateDevice: MemTracker:...
* App does not include DEBUG_REPORT as that is a global extension.
* TODO: GetExtensionSupport must not report DEBUG_REPORT when using instance.
* App MUST include any desired validation layers or they will not participate
* in the device call chain.
* App creates a callback object: fn(..., &MsgCallbackObject2)
* Loader's vkCreateMsgCallback is called.
* Loader sends call down instance chain - this is a global extension - any
* validation layer that was
* enabled at CreateInstance will be able to register the callback. Loader will
* iterate over the ICDs and
* will record the ICD's version of the MsgCallback2 object here.
* ...
* Any report will go to the layer's report function and it will check the flags
* for MsgCallbackObject1
* and MsgCallbackObject2 and take the appropriate action as indicated by the
* app.
* ...
* App calls vkDestroyMsgCallback( MsgCallbackObject1 )
* Loader's DestroyMsgCallback is where call starts. DestroyMsgCallback will be
* sent down instance chain
* ending in the loader's DestroyMsgCallback terminator which will iterate over
* the ICD's destroying each
* ICD version of that MsgCallback object and then destroy the loader's version
* of the object.
* Any reports generated after this will only have MsgCallbackObject2 available.
