Hi Tom, Steven,
I'm currently doing some tests with the event triggers
(git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace.git
for-next).
At the moment I can't use event triggers with probes dynamically

/sys/kernel/debug/tracing/kprobe_events)

This patch implements a new tracing mechanism based on kprobes and using GPIO.
Debugging with GPIO is very common in the embedded world. At least for those of
us
fortunate enough to have an oscilloscope or a logic analyzer on their bench...
This is especially true if the issue results of a hardwar
