Presentation slides.

This presentation (available as PDF) introduces LTTng 2.0, detailing its new features. Amongst these, the most welcome are be the ability to use it on vanilla and distribution kernels, as well as the ability to hook on Tracepoints, Kprobes, Ftrace function tracing and Perf PMU counters. The new integrated command line interface for both the kernel and user-space tracers (LTTng and UST) will be presented. The new Common Trace Format (CTF) natively produced by LTTng 2.0 will be described.

The projects CTF and BabelTrace now have their web page on the efficios website.

The Common Trace Format (CTF) is proposed as a trace format that suits the needs of the embedded, telecom, high-performance and kernel communities. BabelTrace is a trace converter between CTF and other trace formats (work in progress).

The project Generic Ring Buffer Library has its own web page on the efficios website.

The Generic Ring Buffer library presents a high-level kernel-level interface that allows programmers to easily create and use a ring buffer instance. It also provides a more advanced client configuration API for clients with more elaborate needs (e.g. tracers).

EfficiOS Inc. is proud to be the first member of the Multicore Association to benefit from their new guest membership program. Working in collaboration with the MCA is promising very interesting results in terms of trace format standard and open source reference implementation.
