551d8244 20 * SIDE stands for "Software Instrumentation Dynamically Enabled"
67337c4a 21 *
2e197497 22 * This is an instrumentation ABI for Linux user-space, which exposes an
67337c4a
MD		 23 * instrumentation type system and facilities allowing a kernel or
24 * user-space tracer to consume user-space instrumentation.
25 *
2e197497 26 * This instrumentation ABI exposes 3 type systems:
67337c4a
MD		 27 *
28 * * Stack-copy type system: This is the core type system which can
29 * represent all supported types and into which all other type systems
30 * can be nested. This type system requires that every type is
31 * statically or dynamically declared and then registered, thus giving
32 * tracers a complete description of the events and their associated
33 * fields before the associated instrumentation is invoked. The
34 * application needs to copy each argument (side_arg_...()) onto the
35 * stack when calling the instrumentation.
36 *
37 * This is the most expressive of the 3 type systems, althrough not the
38 * fastest due to the extra copy of the arguments.
39 *
40 * * Data-gathering type system: This type system requires every type to
41 * be statically or dynamically declared and registered, but does not
42 * require the application to copy its arguments onto the stack.
43 * Instead, the type description contains all the required information
44 * to fetch the data from the application memory. The only argument
45 * required from the instrumentation is the base pointer from which
46 * the data should be fetched.
47 *
48 * This type system can be used as an event field, or nested within
49 * the stack-copy type system. Nesting of gather-vla within
50 * gather-array and gather-vla types is not allowed.
51 *
52 * This type system is has the least overhead of the 3 type systems.
53 *
54 * * Dynamic type system: This type system receives both type
55 * description and actual data onto the stack at runtime. It has more
56 * overhead that the 2 other type systems, but does not require a
57 * prior registration of event field description. This makes it useful
58 * for seldom used types which are not performance critical, but for
59 * which registering each individual events would needlessly grow the
60 * number of events to declare and register.
61 *
62 * Another use-case for this type system is for use by dynamically
63 * typed language runtimes, where the field type is only known when
64 * the instrumentation is called.
65 *
66 * Those dynamic types can be either used as arguments to a variadic
67 * field list, or as on-stack instrumentation argument for a static
68 * type SIDE_TYPE_DYNAMIC place holder in the stack-copy type system.
2e197497
MD		 69 *
70 * The extensibility scheme for the SIDE ABI is as follows:
71 *
72 * * Existing field types are never changed nor extended. Field types
73 * can be added to the ABI by reserving a label within
74 * enum side_type_label.
75 * * Existing attribute types are never changed nor extended. Attribute
76 * types can be added to the ABI by reserving a label within
77 * enum side_attr_type.
78 * * Each union part of the ABI has an explicit side defined by a
79 * side_padding() member. Each structure and union have a static
80 * assert validating its size.
81 *
82 * Handling of unknown types by the tracers:
83 *
84 * * A tracer may choose to support only a subset of the types supported
85 * by libside. When encountering an unknown or unsupported type, the
86 * tracer has the option to either disallow the entire event or skip
87 * over the unknown type, both at event registration and when
88 * receiving the side_call arguments.
89 *
441235e7 90 * * Event descriptions can be extended by adding fields at the end of
f60d8121
MD		 91 * the structure. The "struct side_event_description" and "struct
92 * side_event_state" are therefore structures with flexible size and
93 * must not be used within arrays.
