18 | * SIDE stands for "Static Instrumentation Dynamically Enabled" | |
19 | * | |
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. | |
23 | * | |
24 | * This instrumentation API exposes 3 type systems: | |
25 | * | |
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. | |
34 | * | |
35 | * This is the most expressive of the 3 type systems, althrough not the | |
36 | * fastest due to the extra copy of the arguments. | |
37 | * | |
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. | |
45 | * | |
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. | |
49 | * | |
50 | * This type system is has the least overhead of the 3 type systems. | |
51 | * | |
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. | |
59 | * | |
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. | |
63 | * | |
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. | |
