551d8244 19 * SIDE stands for "Software Instrumentation Dynamically Enabled"
67337c4a 20 *
2e197497 21 * This is an instrumentation ABI for Linux user-space, which exposes an
67337c4a
MD		 22 * instrumentation type system and facilities allowing a kernel or
23 * user-space tracer to consume user-space instrumentation.
24 *
2e197497 25 * This instrumentation ABI exposes 3 type systems:
67337c4a
MD		 26 *
27 * * Stack-copy type system: This is the core type system which can
28 * represent all supported types and into which all other type systems
29 * can be nested. This type system requires that every type is
30 * statically or dynamically declared and then registered, thus giving
31 * tracers a complete description of the events and their associated
32 * fields before the associated instrumentation is invoked. The
33 * application needs to copy each argument (side_arg_...()) onto the
34 * stack when calling the instrumentation.
35 *
36 * This is the most expressive of the 3 type systems, althrough not the
37 * fastest due to the extra copy of the arguments.
38 *
39 * * Data-gathering type system: This type system requires every type to
40 * be statically or dynamically declared and registered, but does not
41 * require the application to copy its arguments onto the stack.
42 * Instead, the type description contains all the required information
43 * to fetch the data from the application memory. The only argument
44 * required from the instrumentation is the base pointer from which
45 * the data should be fetched.
46 *
47 * This type system can be used as an event field, or nested within
48 * the stack-copy type system. Nesting of gather-vla within
49 * gather-array and gather-vla types is not allowed.
50 *
51 * This type system is has the least overhead of the 3 type systems.
52 *
53 * * Dynamic type system: This type system receives both type
54 * description and actual data onto the stack at runtime. It has more
55 * overhead that the 2 other type systems, but does not require a
56 * prior registration of event field description. This makes it useful
57 * for seldom used types which are not performance critical, but for
58 * which registering each individual events would needlessly grow the
59 * number of events to declare and register.
60 *
61 * Another use-case for this type system is for use by dynamically
62 * typed language runtimes, where the field type is only known when
63 * the instrumentation is called.
64 *
65 * Those dynamic types can be either used as arguments to a variadic
66 * field list, or as on-stack instrumentation argument for a static
67 * type SIDE_TYPE_DYNAMIC place holder in the stack-copy type system.
2e197497
MD		 68 *
69 * The extensibility scheme for the SIDE ABI is as follows:
70 *
71 * * Existing field types are never changed nor extended. Field types
72 * can be added to the ABI by reserving a label within
73 * enum side_type_label.
74 * * Existing attribute types are never changed nor extended. Attribute
75 * types can be added to the ABI by reserving a label within
76 * enum side_attr_type.
77 * * Each union part of the ABI has an explicit side defined by a
78 * side_padding() member. Each structure and union have a static
79 * assert validating its size.
80 *
81 * Handling of unknown types by the tracers:
82 *
83 * * A tracer may choose to support only a subset of the types supported
84 * by libside. When encountering an unknown or unsupported type, the
85 * tracer has the option to either disallow the entire event or skip
86 * over the unknown type, both at event registration and when
87 * receiving the side_call arguments.
88 *
89 * TODO: extend event description with new fields ?
67337c4a

91
92//TODO: as those structures will be ABI, we need to either consider them
93//fixed forever, or think of a scheme that would allow their binary
94//representation to be extended if need be.
