      perf top: Show backtrace when handling a SIGSEGV on --stdio mode · 09f4d78a
      Arnaldo Carvalho de Melo 提交于
      It was just freezing instead of informing about the SEGV, fix it and
      also print a backtrace, just like in the TUI mode and in 'perf trace'.
      
      Tested by provoking a NULL deref when pressing 'z':

      perf top: Allow disabling/enabling events dynamicly · 5d484f99
      Arnaldo Carvalho de Melo 提交于
      Now it is possible to press CTRL+z at anytime and that will disable the
      events being monitored, essentially turning 'top' into 'report', with
      pressing CTRL+z again making it enable the events again, returning to
      the 'top' behaviour, i.e. dynamic + decaying of older samples.
      
      One may want, for instance, play with:
      
          -d, --delay <n>       number of seconds to delay between refreshes
      
      and:
      
          -z, --zero            zero history across updates
      
      Plus CTRL+z to see only the events since last zeroing, etc.
