Hi
It does not seem possible to use set-output between
task contexts of different types (e.g. a software event
to a hardware event)
If you look at perf_event_set_output():
/*
* If its not a per-cpu rb, it must be the same task.
*/
if (output_event->cpu == -1 && output_event->ctx != event->ctx)
goto out;
ctx (perf_event_context) won't be the same for events
of different types. Is this restriction necessary?
Regards
Adrian
