-// an AIDL interface in a backward-incompatible way, e.g., deleting a function
-// from an interface or a field from a parcelable and it broke the build. That
-// breakage is intended.
-//
-// You must not make a backward incompatible changes to the AIDL files built
-// with the aidl_interface module type with versions property set. The module
-// type is used to build AIDL files in a way that they can be used across
-// independently updatable components of the system. If a device is shipped
-// with such a backward incompatible change, it has a high risk of breaking
-// later when a module using the interface is updated, e.g., Mainline modules.

 `unvalidatedConvert` functions operate on types that are either used in a HIDL method call directly
 (i.e., not as a nested class) or used in a subsequent version of the NN HAL. Prefer using `convert`
 over `unvalidatedConvert`.
+
+# HIDL Interface Lifetimes across Processes
+
+Some notes about HIDL interface objects and lifetimes across processes:
+
+All HIDL interface objects inherit from `IBase`, which itself inherits from `::android::RefBase`. As
+such, all HIDL interface objects are reference counted and must be owned through `::android::sp` (or
+referenced through `::android::wp`). Allocating `RefBase` objects on the stack will log errors and
+may result in crashes, and deleting a `RefBase` object through another means (e.g., "delete",
+"free", or RAII-cleanup through `std::unique_ptr` or some equivalent) will result in double-free
+and/or use-after-free undefined behavior.
+
+HIDL/Binder manages the reference count of HIDL interface objects automatically across processes. If
+a process that references (but did not create) the HIDL interface object dies, HIDL/Binder ensures
+any reference count it held is properly released. (Caveat: it might be possible that HIDL/Binder
+behave strangely with `::android::wp` references.)
+
+If the process which created the HIDL interface object dies, any call on this object from another
+process will result in a HIDL transport error with the code `DEAD_OBJECT`.
+
+# Protecting Asynchronous Calls across HIDL
+
+Some notes about asynchronous calls across HIDL:
+
+For synchronous calls across HIDL, if an error occurs after the function was called but before it
+returns, HIDL will return a transport error. For example, if the message cannot be delivered to the
+server process or if the server process dies before returning a result, HIDL will return from the
+function with the appropriate transport error in the `Return<>` object, which can be queried with
+`Return<>::isOk()`, `Return<>::isDeadObject()`, `Return<>::description()`, etc.
+
+However, HIDL offers no such error management in the case of asynchronous calls. By default, if the
+client launches an asynchronous task and the server fails to return a result through the callback,
+the client will be left waiting indefinitely for a result it will never receive.
+
+In the NNAPI, `IDevice::prepareModel*` and `IPreparedModel::execute*` (but not
+`IPreparedModel::executeSynchronously*`) are asynchronous calls across HIDL. Specifically, these
+asynchronous functions are called with a HIDL interface callback object (`IPrepareModelCallback` for
+`IDevice::prepareModel*` and `IExecutionCallback` for `IPreparedModel::execute*`) and are expected
+to quickly return, and the results are returned at a later time through these callback objects.
+
+To protect against the case when the server dies after the asynchronous task was called successfully
+but before the results could be returned, HIDL provides an object called a "`hidl_death_recipient`,"
+which can be used to detect when an interface object (and more generally, the server process) has
+died. nnapi/hal/ProtectCallback.h's `DeathHandler` uses `hidl_death_recipient`s to detect when the
+driver process has died, and `DeathHandler` will unblock any thread waiting on the results of an
+`IProtectedCallback` callback object that may otherwise not be signaled. In order for this to work,
+the `IProtectedCallback` object must have been registered via `DeathHandler::protectCallback()`.

+// You must not make a backward incompatible changes to the AIDL files built
