Subject: [PATCH 17/19] perf, c2c: Dump rbtree for debugging
Date: Fri, 28 Feb 2014 12:43:06 -0500 [thread overview]
Message-ID: <1393609388-40489-18-git-send-email-dzickus@redhat.com> (raw)
In-Reply-To: <1393609388-40489-1-git-send-email-dzickus@redhat.com>
Sometimes you want to verify the rbtree sorting on a unique id
is working correctly. This allows you to dump it.
Sample output:
Idx Hit Maj Min Ino InoGen Pid Daddr Iaddr Data Src (string) cpumode
0 0 0 0 0 0 22 ffffffff813044cf 48080184 [STORE,L1,MISS,SNP NA] 1
