    perf help: Use HAVE_LIBTRACEEVENT to filter out unsupported commands · 55c41f2e
    Yang Jihong authored
    Commands such as kmem, kwork, lock, sched, trace and timechart depend on
    libtraceevent, these commands need to be isolated using HAVE_LIBTRACEEVENT
    macro when cmdlist generation.
    
    The output of the generate-cmdlist.sh script is as follows:
    
      # ./util/generate-cmdlist.sh
      /* Automatically generated by ./util/generate-cmdlist.sh */
      struct cmdname_help
      {
          char name[16];
          char help[80];
      };
    
      static struct cmdname_help common_cmds[] = {
        {"annotate", "Read perf.data (created by perf record) and display annotated code"},
        {"archive", "Create archive with object files with build-ids found in perf.data file"},
        {"bench", "General framework for benchmark suites"},
        {"buildid-cache", "Manage build-id cache."},
        {"buildid-list", "List the buildids in a perf.data file"},
        {"c2c", "Shared Data C2C/HITM Analyzer."},
        {"config", "Get and set variables in a configuration file."},
        {"daemon", "Run record sessions on background"},
        {"data", "Data file related processing"},
        {"diff", "Read perf.data files and display the differential profile"},
        {"evlist", "List the event names in a perf.data file"},
        {"ftrace", "simple wrapper for kernel's ftrace functionality"},
        {"inject", "Filter to augment the events stream with additional information"},
        {"iostat", "Show I/O performance metrics"},
        {"kallsyms", "Searches running kernel for symbols"},
        {"kvm", "Tool to trace/measure kvm guest os"},
        {"list", "List all symbolic event types"},
        {"mem", "Profile memory accesses"},
        {"record", "Run a command and record its profile into perf.data"},
        {"report", "Read perf.data (created by perf record) and display the profile"},
        {"script", "Read perf.data (created by perf record) and display trace output"},
        {"stat", "Run a command and gather performance counter statistics"},
        {"test", "Runs sanity tests."},
        {"top", "System profiling tool."},
        {"version", "display the version of perf binary"},
      #ifdef HAVE_LIBELF_SUPPORT
        {"probe", "Define new dynamic tracepoints"},
      #endif /* HAVE_LIBELF_SUPPORT */
      #if defined(HAVE_LIBTRACEEVENT) && (defined(HAVE_LIBAUDIT_SUPPORT) || defined(HAVE_SYSCALL_TABLE_SUPPORT))
        {"trace", "strace inspired tool"},
      #endif /* HAVE_LIBTRACEEVENT && (HAVE_LIBAUDIT_SUPPORT || HAVE_SYSCALL_TABLE_SUPPORT) */
      #ifdef HAVE_LIBTRACEEVENT
        {"kmem", "Tool to trace/measure kernel memory properties"},
        {"kwork", "Tool to trace/measure kernel work properties (latencies)"},
        {"lock", "Analyze lock events"},
        {"sched", "Tool to trace/measure scheduler properties (latencies)"},
        {"timechart", "Tool to visualize total system behavior during a workload"},
      #endif /* HAVE_LIBTRACEEVENT */
      };
