This plugin adds fields resolving for following tracepoint events: xen:xen_mc_entry xen:xen_mc_extend_args The diff of 'perf script' output generated by old and new code: (data was generated by 'perf record -e 'xen:*' ls') --- script.xen.old +++ script.xen.new - swapper 0 [002] 136.267492: xen:xen_mc_entry: [FAILED TO PARSE] op=3 nargs=2 args=ARRAY[18, 00, 00, 00, 00, 00, 00, 00, 00, e0, d4, 4b, 04, 88, ff, ff, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00] + swapper 0 [002] 136.267492: xen:xen_mc_entry: op 3(stack_switch) args [18, 0, 0, 0, 0, 0] - perf 1970 [008] 136.273319: xen:xen_mc_extend_args: [FAILED TO PARSE] op=1 args=16 res=1 + perf 1970 [008] 136.273319: xen:xen_mc_extend_args: extending op 1(mmu_update) by 16 bytes res ???
