From f7e7ee36757f68778700cde1aaed89e1d23e59fd Mon Sep 17 00:00:00 2001 From: "austin_zhang@linux.intel.com" Date: Fri, 5 Feb 2010 09:02:42 -0800 Subject: [PATCH] perf record: Fix existing process callgraph symbol When 'perf record -g' a existing process, even with debuginfo packages, still cannnot get symbol from 'perf report'. try: perf record -g -p `pidof xxx` -f perf report 68.26% :1181 b74870f2 [.] 0x000000b74870f2 | |--32.09%-- 0xb73b5b44 | 0xb7487102 | 0xb748a4e2 | 0xb748633d | 0xb73b41cd | 0xb73b4467 | 0xb747d531 The reason is: for existing process, in __cmd_record(), the pid is 0 rather than the existing process id.
