18 * SIDE stands for "Software Instrumentation Dynamically Enabled"
20 * This is an instrumentation API for Linux user-space, which exposes an
21 * instrumentation type system and facilities allowing a kernel or
22 * user-space tracer to consume user-space instrumentation.
24 * This instrumentation API exposes 3 type systems:
26 * * Stack-copy type system: This is the core type system which can
27 * represent all supported types and into which all other type systems
28 * can be nested. This type system requires that every type is
29 * statically or dynamically declared and then registered, thus giving
30 * tracers a complete description of the events and their associated
31 * fields before the associated instrumentation is invoked. The
32 * application needs to copy each argument (side_arg_...()) onto the
33 * stack when calling the instrumentation.
35 * This is the most expressive of the 3 type systems, althrough not the
36 * fastest due to the extra copy of the arguments.
38 * * Data-gathering type system: This type system requires every type to
39 * be statically or dynamically declared and registered, but does not
40 * require the application to copy its arguments onto the stack.
41 * Instead, the type description contains all the required information
42 * to fetch the data from the application memory. The only argument
43 * required from the instrumentation is the base pointer from which
44 * the data should be fetched.
46 * This type system can be used as an event field, or nested within
47 * the stack-copy type system. Nesting of gather-vla within
48 * gather-array and gather-vla types is not allowed.
50 * This type system is has the least overhead of the 3 type systems.
52 * * Dynamic type system: This type system receives both type
53 * description and actual data onto the stack at runtime. It has more
54 * overhead that the 2 other type systems, but does not require a
55 * prior registration of event field description. This makes it useful
56 * for seldom used types which are not performance critical, but for
57 * which registering each individual events would needlessly grow the
58 * number of events to declare and register.
60 * Another use-case for this type system is for use by dynamically
61 * typed language runtimes, where the field type is only known when
62 * the instrumentation is called.
64 * Those dynamic types can be either used as arguments to a variadic
65 * field list, or as on-stack instrumentation argument for a static
66 * type SIDE_TYPE_DYNAMIC place holder in the stack-copy type system.
69 //TODO: as those structures will be ABI, we need to either consider them
70 //fixed forever, or think of a scheme that would allow their binary
71 //representation to be extended if need be.
