From add07ccd9222ba0944df2a6d39c6e38de90cd0c5 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Tue, 30 Jun 2020 16:39:34 +0300 Subject: perf intel-pt: Fix displaying PEBS-via-PT with registers After recording PEBS-via-PT, perf script will not accept 'iregs' field e.g. # perf record -c 10000 -e '{intel_pt/branch=0/,branch-loads/aux-output/ppp}' -I -- ls -l ... [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.062 MB perf.data ] # ./perf script --itrace=eop -F+iregs Samples for 'dummy:u' event do not have IREGS attribute set. Cannot print 'iregs' field. Fix by using allow_user_set, which is true when recording AUX area data.
