just wanted to know that if DTrace uses any hardware support for its function.
thanks in advance
No, DTrace doesn't require any hardware support. Just to help clarify,
DTrace is an observability framework that allows you to trace software
events. 'Events' is a pretty generic word in this context, but the cool
thing is that DTrace allows you to observe any kind of event. From core
kernel events (for instance, scheduling or virtual memory events), to
syscalls, library routines, user land code, ... everything.
So it's all in the software, no hardware needed.
Hope that helps.
