From 9880ce4a69ba5c66a5ffdd711fe446bd0226bd8c Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Thu, 18 Aug 2016 17:59:07 +0900 Subject: [PATCH] perf probe: Use hexadecimal type by default if possible Use hexadecimal type by default if it is available on current running kernel. This keeps the default behavior of perf probe after changing the output format of 'u8/16/32/64' to unsigned decimal number.
