Our Projects
We actively develop and maintain many open-source software projects.
LTTng (Linux Trace Toolkit: next generation) is a kernel and application tracer for Linux. It gathers information about applications and important system events to help diagnose application, library and operating system misuses.
We contribute to and maintain parts of the Linux kernel,
namely the tracepoint instrumentation API, the
membarrier(2)
system call, and we actively work on the rseq(2)
(Restartable
Sequences) system call.
Common Trace Format
The Common Trace Format (CTF) is proposed as a trace format that suits the needs of the embedded, telecom, high performance, and kernel communities.
barectf (from bare metal and CTF) is a generator of tracers (ANSI C) which produce Common Trace Format data streams.
Babeltrace is a trace reader and converter engine. It is a reference implementation of the Common Trace Format (CTF).
Userspace RCU
The Userspace RCU library (liburcu) is a highly scalable LGPL synchronization library providing very low overhead and linearly scalable read-side synchronization, as well as efficient data structures based on RCU and lock-free algorithms.
