+
+@section Implementation Status and Implementation-Defined Behavior
+
+We're implementing the OpenACC Profiling Interface as defined by the
+OpenACC 2.6 specification. We're clarifying some aspects here as
+@emph{implementation-defined behavior}, while they're still under
+discussion within the OpenACC Technical Committee.
+
+This implementation is tuned to keep the performance impact as low as
+possible for the (very common) case that the Profiling Interface is
+not enabled. This is relevant, as the Profiling Interface affects all
+the @emph{hot} code paths (in the target code, not in the offloaded
+code). Users of the OpenACC Profiling Interface can be expected to
+understand that performance will be impacted to some degree once the
+Profiling Interface has gotten enabled: for example, because of the
+@emph{runtime} (libgomp) calling into a third-party @emph{library} for
+every event that has been registered.
+
+We're not yet accounting for the fact that @cite{OpenACC events may
+occur during event processing}.
+
+We're not yet implementing initialization via a
+@code{acc_register_library} function that is either statically linked
+in, or dynamically via @env{LD_PRELOAD}.
+Initialization via @code{acc_register_library} functions dynamically
+loaded via the @env{ACC_PROFLIB} environment variable does work, as
+does directly calling @code{acc_prof_register},
+@code{acc_prof_unregister}, @code{acc_prof_lookup}.
+
+As currently there are no inquiry functions defined, calls to
+@code{acc_prof_lookup} will always return @code{NULL}.
+
+There aren't separate @emph{start}, @emph{stop} events defined for the
+event types @code{acc_ev_create}, @code{acc_ev_delete},
+@code{acc_ev_alloc}, @code{acc_ev_free}. It's not clear if these
+should be triggered before or after the actual device-specific call is
+made. We trigger them after.
+
+Remarks about data provided to callbacks:
+
+@table @asis
+
+@item @code{acc_prof_info.event_type}
+It's not clear if for @emph{nested} event callbacks (for example,
+@code{acc_ev_enqueue_launch_start} as part of a parent compute
+construct), this should be set for the nested event
+(@code{acc_ev_enqueue_launch_start}), or if the value of the parent
+construct should remain (@code{acc_ev_compute_construct_start}). In
+this implementation, the value will generally correspond to the
+innermost nested event type.
+
+@item @code{acc_prof_info.device_type}
+@itemize
+
+@item
+For @code{acc_ev_compute_construct_start}, and in presence of an
+@code{if} clause with @emph{false} argument, this will still refer to
+the offloading device type.
+It's not clear if that's the expected behavior.
+
+@item
+Complementary to the item before, for
+@code{acc_ev_compute_construct_end}, this is set to
+@code{acc_device_host} in presence of an @code{if} clause with
+@emph{false} argument.
+It's not clear if that's the expected behavior.
+
+@end itemize
+
+@item @code{acc_prof_info.thread_id}
+Always @code{-1}; not yet implemented.
+
+@item @code{acc_prof_info.async}
+@itemize
+
+@item
+Not yet implemented correctly for
+@code{acc_ev_compute_construct_start}.
+
+@item
+In a compute construct, for host-fallback
+execution/@code{acc_device_host} it will always be
+@code{acc_async_sync}.
+It's not clear if that's the expected behavior.
+
+@item
+For @code{acc_ev_device_init_start} and @code{acc_ev_device_init_end},
+it will always be @code{acc_async_sync}.
+It's not clear if that's the expected behavior.
+
+@end itemize
+
+@item @code{acc_prof_info.async_queue}
+There is no @cite{limited number of asynchronous queues} in libgomp.
+This will always have the same value as @code{acc_prof_info.async}.
+
+@item @code{acc_prof_info.src_file}
+Always @code{NULL}; not yet implemented.
+
+@item @code{acc_prof_info.func_name}
+Always @code{NULL}; not yet implemented.
+
+@item @code{acc_prof_info.line_no}
+Always @code{-1}; not yet implemented.

+@emph{before} @code{acc_ev_compute_construct_start}.
+It's not clear what to do: the standard asks us provide a lot of
+details to the @code{acc_ev_compute_construct_start} callback, without
+(implicitly) initializing a device before?
