| |
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.
