From dd42baf1f64d7257258fa4f20064aee5160df369 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Sun, 21 Feb 2016 23:22:34 +0900 Subject: [PATCH] perf tools: Fix assertion failure on dynamic entry The dynamic entry is created for each field in a tracepoint event. Since they have no fixed hpp format index, it should skip when perf_hpp__reset_width() is called. This caused following assertion failure.. $ perf record -e sched:sched_switch -a sleep 1 $ perf report -s comm,next_pid --stdio perf: ui/hist.c:651: perf_hpp__reset_width: Assertion `!(fmt->idx >= PERF_HPP__MAX_INDEX)' failed.
