====== Future of tracing (wish list edition) ======

Saturday, October 21, 2017 • 14:30 - 15:20

----

===== Abstract =====
Tracing has been an important part of development of Real Time for
Linux. Ftrace, the official tracer inside the Linux kernel came from
the PREEMPT_RT patch. A lot of advancements in tracing have happened
since ftrace was first introduced in 2.6.30 back in 2009, but more can
be accomplished. This session will be more about future development
than discussing what it currently does. Some near term development
include Tom Zanussi's histogram work. Adding tracepoints to irq/preempt
disabling, perhaps even make irq/preempt latency tracing near-zero
overhead to keep enabled in production systems. This will be discussion
oriented, so bring with you what you want to see happen in ftrace, and
ways it can improve.

===== Audience =====

The audience is anyone that is interested in the workings of the Linux
kernel. If you like to see how your processes are scheduled, how page
faults affect your applications, what interrupts are causing latencies
etc. Then you may like to take part in this talk/discussion.
