+ * 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:
+ * This instrumentation ABI exposes 3 type systems:
*
* * Stack-copy type system: This is the core type system which can
* represent all supported types and into which all other type systems
* 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.
+ *
+ * The extensibility scheme for the SIDE ABI is as follows:
+ *
+ * * Existing field types are never changed nor extended. Field types
+ * can be added to the ABI by reserving a label within
+ * enum side_type_label.
+ * * Existing attribute types are never changed nor extended. Attribute
+ * types can be added to the ABI by reserving a label within
+ * enum side_attr_type.
+ * * Each union part of the ABI has an explicit side defined by a
+ * side_padding() member. Each structure and union have a static
+ * assert validating its size.
+ *
+ * Handling of unknown types by the tracers:
+ *
+ * * A tracer may choose to support only a subset of the types supported
+ * by libside. When encountering an unknown or unsupported type, the
+ * tracer has the option to either disallow the entire event or skip
+ * over the unknown type, both at event registration and when
+ * receiving the side_call arguments.
+ *
+ * * Event descriptions can be extended by adding fields at the end of
+ * the structure. The "struct side_event_description" and "struct
+ * side_event_state" are therefore structures with flexible size and
+ * must not be used within arrays.
*/
