Subject: Reading perf counters at ftrace trace boundaries
Date: Sun, 11 Aug 2013 21:03:09 -0300 [thread overview]
Message-ID: <5208263D.2080205@opersys.com> (raw)
Wondering if there's a way for reading perf counters in the kernel. I'd
like to read/record perf counters on ftrace function tracing
entries/exits to provide a rundown of the value of various counters on
function call boundaries.
[ Steven: apologies for sending you a duplicate here of what I somewhat
already sent privately. ]
