-Subject: lttng instrumentation: tracepoint events
-
-Modifications to the in-kernel TRACE_EVENT are needed to generate the
-compact event descriptions and the probe code LTTng generates. These
-changes could apply to upstream TRACE_EVENT, but requires changing the
-in-kernel API.

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

-Subject: lttng: debugfs and procfs ABI
-
-Add the "lttng" virtual file to debugfs and procfs. All operations are
-performed through ioctls (LTTng ioctl range is already reserved
-upstream) on this virtual file and on anonymous file descriptors
-returned by these ioctls. Each file descriptor is associated with a
-tracer "object" (session, channel, stream, event, context).

-+LTTng 2.0 modules
-+
-+Mathieu Desnoyers
-+November 1st, 2011
-+
-+LTTng 2.0 kernel modules is currently part of the Linux kernel staging
-+tree. It features (new features since LTTng 0.x):
-+
-+- Produces CTF (Common Trace Format) natively,
-+ (http://www.efficios.com/ctf)
-+- Tracepoints, Function tracer, CPU Performance Monitoring Unit (PMU)
-+ counters, kprobes, and kretprobes support,
-+- Integrated interface for both kernel and userspace tracing,
-+- Have the ability to attach "context" information to events in the
-+ trace (e.g. any PMU counter, pid, ppid, tid, comm name, etc).
-+ All the extra information fields to be collected with events are
-+ optional, specified on a per-tracing-session basis (except for
-+ timestamp and event id, which are mandatory).
-+
-+To build and install, you need to select "Staging" modules, and the
-+LTTng kernel tracer.
-+
-+Use lttng-tools to control the tracer. LTTng tools should automatically
-+load the kernel modules when needed. Use Babeltrace to print traces as a
-+human-readable text log. These tools are available at the following URL:
-+http://lttng.org/lttng2.0
-+
-+Please note that the LTTng-UST 2.0 (user-space tracing counterpart of
-+LTTng 2.0) is now ready to be used, but still only available from the
-+git repository.
-+
-+So far, it has been tested on vanilla Linux kernels 2.6.38, 2.6.39 and
-+3.0 (on x86 32/64-bit, and powerpc 32-bit at the moment, build tested on
-+ARM). It should work fine with newer kernels and other architectures,
-+but expect build issues with kernels older than 2.6.36. The clock source
-+currently used is the standard gettimeofday (slower, less scalable and
-+less precise than the LTTng 0.x clocks). Support for LTTng 0.x clocks
-+will be added back soon into LTTng 2.0. Please note that lttng-modules
-+2.0 can build on a Linux kernel patched with the LTTng 0.x patchset, but
-+the lttng-modules 2.0 replace the lttng-modules 0.x, so both tracers
-+cannot be installed at the same time for a given kernel version.
-+
-+* Note about Perf PMU counters support
-+
-+Each PMU counter has its zero value set when it is attached to a context with
-+add-context. Therefore, it is normal that the same counters attached to both the
-+stream context and event context show different values for a given event; what
-+matters is that they increment at the same rate.

-+Please contact Mathieu Desnoyers <mathieu.desnoyers@efficios.com> for
-+questions about this TODO list. The "Cleanup/Testing" section would be
-+good to go through before integration into mainline. The "Features"
-+section is a wish list of features to complete before releasing the
-+"LTTng 2.0" final version, but are not required to have LTTng working.
-+These features are mostly performance enhancements and instrumentation
-+enhancements.
-+
-+TODO:
-+
-+A) Cleanup/Testing
-+
-+ 1) Remove debugfs "lttng" file (keep only procfs "lttng" file).
-+ The rationale for this is that this file is needed for
-+ user-level tracing support (LTTng-UST 2.0) intended to be
-+ used on production system, and therefore should be present as
-+ part of a "usually mounted" filesystem rather than a debug
-+ filesystem.
-+
-+ 2) Cleanup wrappers. The drivers/staging/lttng/wrapper directory
-+ contains various wrapper headers that use kallsyms lookups to
-+ work around some missing EXPORT_SYMBOL_GPL() in the mainline
-+ kernel. Ideally, those few symbols should become exported to
-+ modules by the kernel.
-+
-+ 3) Test lib ring buffer snapshot feature.
-+ When working on the lttngtop project, Julien Desfossez
-+ reported that he needed to push the consumer position
-+ forward explicitely with lib_ring_buffer_put_next_subbuf.
-+ This means that although the usual case of pairs of
-+ lib_ring_buffer_get_next_subbuf/lib_ring_buffer_put_next_subbuf
-+ work fine, there is probably a problem that needs to be
-+ investigated in
-+ lib_ring_buffer_get_subbuf/lib_ring_buffer_put_subbuf, which
-+ depend on the producer to push the reader position.
-+ Contact: Julien Desfossez <julien.desfossez@polymtl.ca>
-+
-+ 4) Test latest -rt kernel support.
-+ There has been report of corrupted traces when tracing a
-+ 3.0.10-rt27 in the area of access_ok() system call event.
-+ Still has to be investigated. Cannot be reproduced with
-+ mainline kernel.
-+ Contact: Yannick Brosseau <yannick.brosseau@polymtl.ca>
-+
-+B) Features
-+
-+ 1) Integration of the LTTng 0.x trace clocks into
-+ LTTng 2.0.
-+ Currently using mainline kernel monotonic clock. NMIs can
-+ therefore not be traced, and this causes a significant
-+ performance degradation compared to the LTTng 0.x trace
-+ clocks. Imply the creation of drivers/staging/lttng/arch to
-+ contain the arch-specific clock support files.
-+ * Dependency: addition of clock descriptions to CTF.
-+ See: http://git.lttng.org/?p=linux-2.6-lttng.git;a=summary
-+ for the LTTng 0.x git tree.
-+
-+ 2) Port OMAP3 LTTng trace clocks to x86 to support systems
-+ without constant TSC.
-+ * Dependency: (B.1)
-+ See: http://git.lttng.org/?p=linux-2.6-lttng.git;a=summary
-+ for the LTTng 0.x git tree.
-+
-+ 3) Implement mmap operation on an anonymous file created by a
-+ LTTNG_KERNEL_CLOCK ioctl to export data to export
-+ synchronized kernel and user-level LTTng trace clocks:
-+ with:
-+ - shared per-cpu data,
-+ - read seqlock.
-+ The content exported by this shared memory area will be
-+ arch-specific.
-+ * Dependency: (B.1) && (B.2)
-+ See: http://git.lttng.org/?p=linux-2.6-lttng.git;a=summary
-+ for the LTTng 0.x git tree, which has vDSO support for
-+ LTTng trace clock on the x86 architecture.
-+
-+ 3) Integrate the "statedump" module from LTTng 0.x into LTTng
-+ 2.0.
-+ * Dependency: addition of "dynamic enumerations" type to CTF.
-+ See: http://git.lttng.org/?p=lttng-modules.git;a=shortlog;h=refs/heads/v0.19-stable
-+ ltt-statedump.c
-+
-+ 4) Generate system call TRACE_EVENT headers for all
-+ architectures (currently done: x86 32/64).
-+
-+ 5) Define "unknown" system calls into instrumentation/syscalls
-+ override files / or do SYSCALL_DEFINE improvements to
-+ mainline kernel to allow automatic generation of these
-+ missing system call descriptions.
-+
-+ 6) Create missing tracepoint event headers files into
-+ instrumentation/events from headers located in
-+ include/trace/events/. Choice: either do as currently done,
-+ and copy those headers locally into the lttng driver and
-+ perform the modifications locally, or push TRACE_EVENT API
-+ modification into mainline headers, which would require
-+ collaboration from Ftrace/Perf maintainers.
-+
-+ 7) Poll: implement a poll and/or epoll exclusive wakeup scheme,
-+ which contradicts POSIX, but protect multiple consumer
-+ threads from thundering herd effect.
-+
-+ 8) Re-integrate sample modules from libringbuffer into
-+ lttng driver. Those modules can be used as example of how to
-+ use libringbuffer in other contexts than LTTng, and are
-+ useful to perform benchmarks of the ringbuffer library.
-+ See: http://www.efficios.com/ringbuffer
-+
-+ 9) NOHZ support for lib ring buffer. NOHZ infrastructure in the
-+ Linux kernel does not support notifiers chains, which does
-+ not let LTTng play nicely with low power consumption setups
-+ for flight recorder (overwrite mode) live traces. One way to
-+ allow integration between NOHZ and LTTng would be to add
-+ support for such notifiers into NOHZ kernel infrastructure.
-+
-+ 10) Turn drivers/staging/lttng/ltt-probes.c probe_list into a
-+ hash table. Turns O(n^2) trace systems registration (cost
-+ for n systems) into O(n). (O(1) per system)
-+
-+ 11) drivers/staging/lttng/probes/lttng-ftrace.c:
-+ LTTng currently uses kretprobes for per-function tracing,
-+ not the function tracer. So lttng-ftrace.c should be used
-+ for "all" function tracing.
-+
-+ 12) drivers/staging/lttng/probes/lttng-types.c:
-+ This is a currently unused placeholder to export entire C
-+ type declarations into the trace metadata, e.g. for support
-+ of describing the layout of structures/enumeration mapping
-+ along with syscall entry events. The design of this support
-+ will likely change though, and become integrated with the
-+ TRACE_EVENT support within lttng, by adding new macros, and
-+ support for generation of metadata from these macros, to
-+ allow description of those compound types/enumerations.

-Subject: lttng: probe callbacks
-
-Implement the LTTng probe callbacks. One notable file here is
-lttng-events.h, which is the core implementation of the LTTng
-TRACE_EVENT macros for generation of probes and tracepoint decription
-from the TRACE_EVENT declarations.

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

-
-bool :1, uchar :1 or uint :1 could make sense. uchar:1/bool:1 won't save
-any space here, because the surrounding fields are either uint or
-pointers, so alignment will just add padding.
-
-I try to use int/uint whenever possible because x86 CPUs tend to get
-less register false-dependencies when using instructions modifying the
-whole register (generated by using int/uint types) rather than only part
-of it (uchar/char/bool). I only use char/uchar/bool when there is a
-clear wanted space gain.
-
-The reason why I never use the bool type within a structure when I want
-a compact representation is that bool takes a whole byte just to
-represent one bit:
-
-struct usebitfield {
- int a;
- unsigned int f:1, g:1, h:1, i:1, j:1;
- int b;
-};
-
-struct usebool {
- int a;
- bool f, g, h, i, j;
- int b;
-};
-
-struct useboolbf {
- int a;
- bool f:1, g:1, h:1, i:1, j:1;
- int b;
-};
-
-int main()
-{
- printf("bitfield %d bytes, bool %d bytes, boolbitfield %d bytes\n",
- sizeof(struct usebitfield), sizeof(struct usebool),
- sizeof(struct useboolbf));
-}
-
-result:
-
-bitfield 12 bytes, bool 16 bytes, boolbitfield 12 bytes
-
-This is because each bool takes one byte, while the bitfields are put in
-units of "unsigned int" (or bool for the 3rd struct). So in this
-example, we need 5 bytes + 3 bytes alignment for the bool, but only 4
-bytes to hold the "unsigned int" unit for the bitfields.
-
-The choice between bool and bitfields must also take into account the
-frequency of access to the variable, because bitfields require mask
-operations to access the selected bit(s). You will notice that none of
-these bitfields are accessed on the tracing fast-path: only in
-slow-paths. Therefore, space gain is more important than speed here.
-
-One might argue that I have so few of these fields here that it does not
-make an actual difference to go for bitfield or bool. I am just trying
-to choose types best suited for their intended purpose, ensuring they
-are future-proof and will allow simply adding more fields using the same
-type, as needed.
-
-So I guess I'll go for uint :1.
