+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).
