| * 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. |
