From 54cf776a9c5c2e6a91de31954bba4d3bad6c657c Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Fri, 20 Feb 2015 23:17:01 +0100 Subject: [PATCH] perf data: Add a 'perf' prefix to the generic fields Some of the tracers bring their own id or pid fields and we can end up having two of them. This patch adds a "perf_" prefix to the 'generic' fields so we avoid a clash of the member names. The change is visible in the babeltrace output: Before: $ babeltrace ./ctf-data/ [03:19:13.962131936] (+0.000001935) cycles: { }, { ip = 0xFFFFFFFF8105443A, tid = 20714, pid = 20714, period = 8 } [03:19:13.962133732] (+0.000001796) cycles: { }, { ip = 0xFFFFFFFF8105443A, tid = 20714, pid = 20714, period = 114 } ... Now: $ babeltrace ./ctf-data/ [03:19:13.962131936] (+0.000001935) cycles: { }, { perf_ip = 0xFFFFFFFF8105443A, perf_tid = 20714, perf_pid = 20714, perf_period = 8 } [03:19:13.962133732] (+0.000001796) cycles: { }, { perf_ip = 0xFFFFFFFF8105443A, perf_tid = 20714, perf_pid = 20714, perf_period = 114 } ...
