From f594bae08183fb6b57db55387794ece3e1edf6f6 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Mon, 7 Mar 2016 16:44:44 -0300 Subject: perf stat: Document --detailed option I'm surprised this remained undocumented since at least 2011. And it is actually a very useful switch, as Steve and I came to realize recently. Add the text from 2cba3ffb9a9d ("perf stat: Add -d -d and -d -d -d options to show more CPU events") which added the incrementing aspect to -d.
