- * This is an instrumentation API for Linux user-space, which exposes an
+ * This is an instrumentation ABI for Linux user-space, which exposes an
* instrumentation type system and facilities allowing a kernel or
* user-space tracer to consume user-space instrumentation.
*
- * This instrumentation API exposes 3 type systems:
+ * The extensibility scheme for the SIDE ABI for event state is as
+ * follows:
*
- * * Stack-copy type system: This is the core type system which can
- * represent all supported types and into which all other type systems
- * can be nested. This type system requires that every type is
- * statically or dynamically declared and then registered, thus giving
- * tracers a complete description of the events and their associated
- * fields before the associated instrumentation is invoked. The
- * application needs to copy each argument (side_arg_...()) onto the
- * stack when calling the instrumentation.
- *
- * This is the most expressive of the 3 type systems, althrough not the
- * fastest due to the extra copy of the arguments.
- *
- * * Data-gathering type system: This type system requires every type to
- * be statically or dynamically declared and registered, but does not
- * require the application to copy its arguments onto the stack.
- * Instead, the type description contains all the required information
- * to fetch the data from the application memory. The only argument
- * required from the instrumentation is the base pointer from which
- * the data should be fetched.
- *
- * This type system can be used as an event field, or nested within
- * the stack-copy type system. Nesting of gather-vla within
- * gather-array and gather-vla types is not allowed.
- *
- * This type system is has the least overhead of the 3 type systems.
- *
- * * Dynamic type system: This type system receives both type
- * description and actual data onto the stack at runtime. It has more
- * overhead that the 2 other type systems, but does not require a
- * prior registration of event field description. This makes it useful
- * for seldom used types which are not performance critical, but for
- * which registering each individual events would needlessly grow the
- * number of events to declare and register.
- *
- * Another use-case for this type system is for use by dynamically
- * typed language runtimes, where the field type is only known when
- * the instrumentation is called.
- *
- * Those dynamic types can be either used as arguments to a variadic
- * field list, or as on-stack instrumentation argument for a static
- * type SIDE_TYPE_DYNAMIC place holder in the stack-copy type system.
+ * * If the semantic of the "struct side_event_state_N" fields change,
+ * the SIDE_EVENT_STATE_ABI_VERSION should be increased. The
+ * "struct side_event_state_N" is not extensible and must have its
+ * ABI version increased whenever it is changed. Note that increasing
+ * the version of SIDE_EVENT_DESCRIPTION_ABI_VERSION is not necessary
+ * when changing the layout of "struct side_event_state_N".
