Staging: lttng: remove from the drivers/staging/ tree
The "proper" way to do this is to work with the existing in-kernel tracing subsystem and work to get the missing features that are in lttng into those subsystems.

1config LTTNG
2 tristate "LTTng kernel tracer"
3 depends on TRACEPOINTS
4 help
5 The LTTng 2.0 Tracer Toolchain allows integrated kernel and
6 user-space tracing from a single user interface: the "lttng"
7 command. See http://lttng.org website for the "lttng-tools"
8 user-space tracer control tools package and the "babeltrace"
9 package for conversion of trace data to a human-readable
10 format.
11
12 LTTng features:
13 - System-wide tracing across kernel, libraries and
14 applications,
15 - Tracepoints, detailed syscall tracing (fast strace replacement),
16 Function tracer, CPU Performance Monitoring Unit (PMU) counters
17 and kprobes support,
18 - Have the ability to attach "context" information to events in the
19 trace (e.g. any PMU counter, pid, ppid, tid, comm name, etc). All
20 the extra information fields to be collected with events are
21 optional, specified on a per-tracing-session basis (except for
22 timestamp and event id, which are mandatory).
23 - Precise and fast clock sources with near cycle-level
24 timestamps,
25 - Efficient trace data transport:
26 - Compact Binary format with CTF,
27 - Per-core buffers ensures scalability,
28 - Fast-paths in caller context, amortized synchronization,
29 - Zero-copy using splice and mmap system calls, over disk,
30 network or consumed in-place,
31 - Multiple concurrent tracing sessions are supported,
32 - Designed to meet hard real-time constraints,
33 - Supports live streaming of the trace data,
34 - Produces CTF (Common Trace Format) natively (see
35 http://www.efficios.com/ctf).

1LTTng 2.0 modules
2
3Mathieu Desnoyers
4November 1st, 2011
5
6LTTng 2.0 kernel modules is currently part of the Linux kernel staging
7tree. It features (new features since LTTng 0.x):
8
9- Produces CTF (Common Trace Format) natively,
10 (http://www.efficios.com/ctf)
11- Tracepoints, Function tracer, CPU Performance Monitoring Unit (PMU)
12 counters, kprobes, and kretprobes support,
13- Integrated interface for both kernel and userspace tracing,
14- Have the ability to attach "context" information to events in the
15 trace (e.g. any PMU counter, pid, ppid, tid, comm name, etc).
16 All the extra information fields to be collected with events are
17 optional, specified on a per-tracing-session basis (except for
18 timestamp and event id, which are mandatory).
19
20To build and install, you need to select "Staging" modules, and the
21LTTng kernel tracer.
22
23Use lttng-tools to control the tracer. LTTng tools should automatically
24load the kernel modules when needed. Use Babeltrace to print traces as a
25human-readable text log. These tools are available at the following URL:
26http://lttng.org/lttng2.0
27
28Please note that the LTTng-UST 2.0 (user-space tracing counterpart of
29LTTng 2.0) is now ready to be used, but still only available from the
30git repository.
31
32So far, it has been tested on vanilla Linux kernels 2.6.38, 2.6.39 and
333.0 (on x86 32/64-bit, and powerpc 32-bit at the moment, build tested on
34ARM). It should work fine with newer kernels and other architectures,
35but expect build issues with kernels older than 2.6.36. The clock source
36currently used is the standard gettimeofday (slower, less scalable and
37less precise than the LTTng 0.x clocks). Support for LTTng 0.x clocks
38will be added back soon into LTTng 2.0. Please note that lttng-modules
392.0 can build on a Linux kernel patched with the LTTng 0.x patchset, but
40the lttng-modules 2.0 replace the lttng-modules 0.x, so both tracers
41cannot be installed at the same time for a given kernel version.
42
43* Note about Perf PMU counters support
44
45Each PMU counter has its zero value set when it is attached to a context with
46add-context. Therefore, it is normal that the same counters attached to both the
47stream context and event context show different values for a given event; what
48matters is that they increment at the same rate.

1Please contact Mathieu Desnoyers <mathieu.desnoyers@efficios.com> for
2questions about this TODO list. The "Cleanup/Testing" section would be
3good to go through before integration into mainline. The "Features"
4section is a wish list of features to complete before releasing the
5"LTTng 2.0" final version, but are not required to have LTTng working.
6These features are mostly performance enhancements and instrumentation
7enhancements.
8
9TODO:
10
11A) Cleanup/Testing
12
13 1) Remove debugfs "lttng" file (keep only procfs "lttng" file).
14 The rationale for this is that this file is needed for
15 user-level tracing support (LTTng-UST 2.0) intended to be
16 used on production system, and therefore should be present as
17 part of a "usually mounted" filesystem rather than a debug
18 filesystem.
19
20 2) Cleanup wrappers. The drivers/staging/lttng/wrapper directory
21 contains various wrapper headers that use kallsyms lookups to
22 work around some missing EXPORT_SYMBOL_GPL() in the mainline
23 kernel. Ideally, those few symbols should become exported to
24 modules by the kernel.
25
26 3) Test lib ring buffer snapshot feature.
27 When working on the lttngtop project, Julien Desfossez
28 reported that he needed to push the consumer position
29 forward explicitely with lib_ring_buffer_put_next_subbuf.
30 This means that although the usual case of pairs of
31 lib_ring_buffer_get_next_subbuf/lib_ring_buffer_put_next_subbuf
32 work fine, there is probably a problem that needs to be
33 investigated in
34 lib_ring_buffer_get_subbuf/lib_ring_buffer_put_subbuf, which
35 depend on the producer to push the reader position.

39B) Features
40
41 1) Integration of the LTTng 0.x trace clocks into
42 LTTng 2.0.
43 Currently using mainline kernel monotonic clock. NMIs can
44 therefore not be traced, and this causes a significant
45 performance degradation compared to the LTTng 0.x trace
46 clocks. Imply the creation of drivers/staging/lttng/arch to
47 contain the arch-specific clock support files.
48 * Dependency: addition of clock descriptions to CTF.
49 See: http://git.lttng.org/?p=linux-2.6-lttng.git;a=summary
50 for the LTTng 0.x git tree.
51
52 2) Port OMAP3 LTTng trace clocks to x86 to support systems
53 without constant TSC.
54 * Dependency: (B.1)
55 See: http://git.lttng.org/?p=linux-2.6-lttng.git;a=summary
56 for the LTTng 0.x git tree.
57
58 3) Implement mmap operation on an anonymous file created by a
59 LTTNG_KERNEL_CLOCK ioctl to export data to export
60 synchronized kernel and user-level LTTng trace clocks:
61 with:
62 - shared per-cpu data,
63 - read seqlock.
64 The content exported by this shared memory area will be
65 arch-specific.
66 * Dependency: (B.1) && (B.2)
67 See: http://git.lttng.org/?p=linux-2.6-lttng.git;a=summary
68 for the LTTng 0.x git tree, which has vDSO support for
69 LTTng trace clock on the x86 architecture.
70
71 3) Integrate the "statedump" module from LTTng 0.x into LTTng
72 2.0.
73 * Dependency: addition of "dynamic enumerations" type to CTF.
74 See: http://git.lttng.org/?p=lttng-modules.git;a=shortlog;h=refs/heads/v0.19-stable
75 ltt-statedump.c
76
77 4) Generate system call TRACE_EVENT headers for all
78 architectures (currently done: x86 32/64).
79
80 5) Define "unknown" system calls into instrumentation/syscalls
81 override files / or do SYSCALL_DEFINE improvements to
82 mainline kernel to allow automatic generation of these
83 missing system call descriptions.
84
85 6) Create missing tracepoint event headers files into
86 instrumentation/events from headers located in
87 include/trace/events/. Choice: either do as currently done,
88 and copy those headers locally into the lttng driver and
89 perform the modifications locally, or push TRACE_EVENT API
90 modification into mainline headers, which would require
91 collaboration from Ftrace/Perf maintainers.
92
93 7) Poll: implement a poll and/or epoll exclusive wakeup scheme,
94 which contradicts POSIX, but protect multiple consumer
95 threads from thundering herd effect.
96
97 8) Re-integrate sample modules from libringbuffer into
98 lttng driver. Those modules can be used as example of how to
99 use libringbuffer in other contexts than LTTng, and are
100 useful to perform benchmarks of the ringbuffer library.
101 See: http://www.efficios.com/ringbuffer
102
103 9) NOHZ support for lib ring buffer. NOHZ infrastructure in the
104 Linux kernel does not support notifiers chains, which does
105 not let LTTng play nicely with low power consumption setups
106 for flight recorder (overwrite mode) live traces. One way to
107 allow integration between NOHZ and LTTng would be to add
108 support for such notifiers into NOHZ kernel infrastructure.
109
110 10) Turn drivers/staging/lttng/ltt-probes.c probe_list into a
111 hash table. Turns O(n^2) trace systems registration (cost
112 for n systems) into O(n). (O(1) per system)
113
114 11) drivers/staging/lttng/probes/lttng-ftrace.c:
115 LTTng currently uses kretprobes for per-function tracing,
116 not the function tracer. So lttng-ftrace.c should be used
117 for "all" function tracing.
118
119 12) drivers/staging/lttng/probes/lttng-types.c:
120 This is a currently unused placeholder to export entire C
121 type declarations into the trace metadata, e.g. for support
122 of describing the layout of structures/enumeration mapping
123 along with syscall entry events. The design of this support
124 will likely change though, and become integrated with the
125 TRACE_EVENT support within lttng, by adding new macros, and
126 support for generation of metadata from these macros, to
127 allow description of those compound types/enumerations.

1LTTng system call tracing
2
31) lttng-syscall-extractor
4
5You need to build a kernel with CONFIG_FTRACE_SYSCALLS=y and
6CONFIG_KALLSYMS_ALL=y for extraction. Apply the linker patch to get your
7kernel to keep the system call metadata after boot. Then build and load
8the LTTng syscall extractor module. The module will fail to load (this
9is expected). See the dmesg output for system call metadata.
10
112) Generate system call TRACE_EVENT().
12
13Take the dmesg metadata and feed it to lttng-syscalls-generate-headers.sh, e.g.,
14from the instrumentation/syscalls directory. See the script header for
15usage example.
16
17After these are created, we just need to follow the new system call additions,
18no need to regenerate the whole thing, since system calls are only appended to.

934 * belongs to, we don't have to synchronize it at all. If we are
935 * migrated, the scheduler will take care of the memory barriers.
936 * Normally, smp_call_function_single() should ensure program order when
937 * executing the remote function, which implies that it surrounds the
938 * function execution with :
939 * smp_mb()
940 * send IPI
941 * csd_lock_wait
942 * recv IPI
943 * smp_mb()
944 * exec. function
945 * smp_mb()
946 * csd unlock
947 * smp_mb()
948 *
949 * However, smp_call_function_single() does not seem to clearly execute
950 * such barriers. It depends on spinlock semantic to provide the barrier
951 * before executing the IPI and, when busy-looping, csd_lock_wait only
952 * executes smp_mb() when it has to wait for the other CPU.
953 *
954 * I don't trust this code. Therefore, let's add the smp_mb() sequence
955 * required ourself, even if duplicated. It has no performance impact
956 * anyway.
957 *
958 * smp_mb() is needed because smp_rmb() and smp_wmb() only order read vs
959 * read and write vs write. They do not ensure core synchronization. We
960 * really have to ensure total order between the 3 barriers running on
961 * the 2 CPUs.
