      tools lib traceevent: Report better error message on bad function args · 3a3ffa2e
      Steven Rostedt authored
      When Jiri Olsa was writing a function callback for
      scsi_trace_parse_cdb(), he thought that the traceevent library had a
      bug in it because he was getting this error:
      
        Error: expected ')' but read ','
        Error: expected ')' but read ','
        Error: expected ')' but read ','
        Error: expected ')' but read ','
      
      But in truth, he didn't have the write number of arguments for the
      function callback, and the error was the library detecting the
      discrepancy. A better error message would have prevented the confusion:
      
        Error: function 'scsi_trace_parse_cdb()' only expects 2 arguments but event scsi_dispatch_cmd_timeout has more
        Error: function 'scsi_trace_parse_cdb()' only expects 2 arguments but event scsi_dispatch_cmd_start has more
        Error: function 'scsi_trace_parse_cdb()' only expects 2 arguments but event scsi_dispatch_cmd_error has more
        Error: function 'scsi_trace_parse_cdb()' only expects 2 arguments but event scsi_dispatch_cmd_done has more
      
      Or
      
        Error: function 'scsi_trace_parse_cdb()' expects 4 arguments but event scsi_dispatch_cmd_timeout only uses 3
        Error: function 'scsi_trace_parse_cdb()' expects 4 arguments but event scsi_dispatch_cmd_start only uses 3
        Error: function 'scsi_trace_parse_cdb()' expects 4 arguments but event scsi_dispatch_cmd_error only uses 3
        Error: function 'scsi_trace_parse_cdb()' expects 4 arguments but event scsi_dispatch_cmd_done only uses 3

      Several cleanups suggested by Namhyung:
      
        * Remove index field from struct func_stack as it's not needed.
      
        * Rename get_index into add_and_get_index.
      
        * Use '%*X' format string capability instead of the loop

      Jiri Olsa authored
      The pevent_print_func_field function encompasses all the functionality
      used in the hrtimer_start handler. Change the handler to use this
      function.
      
      This also unifies the function field output with the
      hrtimer_expire_entry handler.

      Removing options support as it's not backported yet.
      Currently this plugin supports 2 options:
       'parent' to display parent function
       'indent' to show function call indents
      
      Enabling both of them by default.

      Note:
       - kvm_mmu_zap_page is replaced by kvm_mmu_prepare_zap_page
         in current kernel, keeping it for backward compatibility
       - some of the tracepoints keep the same output even with
         the plugin handling: kvm:kvm_exit, kvm:kvm_emulate_insn
       - the 'kvmmmu:fast_page_fault' is still broken because of
         missing is_writable_pte function and is fixed in another patch
       - ommited following tracepoints from backport because
         the output was buggy

      perf tools: Add trace-event global object for tracepoint interface · 97978b3e
      Jiri Olsa authored
      In order to get the proper plugins processing we need to use full
      trace-event interface when creating tracepoint events. So far we were
      using shortcut to get the parsed format.
      
      Moving current 'event_format__new' function into trace-event object as
      'trace_event__tp_format'.
      
      This function uses properly initialized global trace-event object,
      ensuring proper plugins processing.

      Changing the pevent_parse_format interface to include the pevent handle.
      
      The goal is to always use pevent object when dealing with traceevent
      library. The reason is that we might need additional processing (like
      plugins), which is not possible otherwise.
      
      Patches follow to make this happen completely.

      Backporting plugin support for traceevent lib.
      
      Backported from Steven Rostedt's trace-cmd repo (HEAD 0f2c2fb):
      git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git
      
      It's now possible to use following interface to load plugins
      (shared objects) to enhance pevent object functionality.
      
      The plugin interface/hooks are as follows:
      (taken from event-parse.h comments)
      
      - 'pevent_plugin_loader' (required)
          The function name to initialized the plugin.
      
          int pevent_plugin_loader(struct pevent *pevent)
      
      - 'pevent_plugin_unloader' (optional)
          The function called just before unloading
      
          int pevent_plugin_unloader(void)
      
      - 'pevent_plugin_options'  (optional)
          Plugin options that can be set before loading
      
          struct plugin_option pevent_plugin_options[] = {
             {
                     .name = "option-name",
                     .plugin_alias = "overide-file-name", (optional)
                     .description = "description of option to show users",
             },
             {
                     .name = NULL,
             },
          };
      
          Array must end with .name = NULL;
      
          The plugin_alias (below) can be used to give a shorter
          name to access the variable. Useful if a plugin handles
          more than one event.
      
          NOTE options support is not backported yet.
      
      - 'pevent_plugin_alias' (optional)
          The name to use for finding options (uses filename if not defined)
      
      New traceevent functions are added to search and load
      available plugins:
      
        struct plugin_list*
        traceevent_load_plugins(struct pevent *pevent)
          - loads plusing for 'struct pevent' object and returns
            loaded plugins list
      
        void traceevent_unload_plugins(struct plugin_list *plugin_list);
          - unload plugin list

      The perf_event__preprocess_sample() function is called in
      process_sample_event().  Instead of calling it again in
      perf_evsel__print_ip(), pass through the resultant addr_location.

      perf symbols: Fix random fd closing with no libelf · 779e24e2
      Adrian Hunter authored
      When built without libelf, perf tools was failing to initialize a file
      descriptor, but nevertheless closing it.  That sometimes resulted in the
      output being truncated because the stdout file descriptor got closed.

      perf kvm: Update the 'record' man page entry for new --guest/--host behavior · 8df0b4ad
      Dongsheng Yang authored
      As we have changed the default behavior of 'perf kvm' to --guest
      enabled, the parts of the man page that covers the 'record' subcommand
      are outdated.
      
      This patch updates it to show the correct output with
      --host/--guest/neither/both of them.

      perf kvm: Fix spurious '=' use in man page · 316bd98a
      Dongsheng Yang authored
      As option --host and --guest request no input for it, there should not
      be a '=' after them in the man page sources.
      
      And --output expects a filename as the input, so there should be a '='
      after it.
      
      This patch removes the needless '=' after --guest and --host, and adds a
      '=' after --output in perf-kvm.txt.

      perf kvm: Add more detail about buildid-list in man page · ed086d5b
      Dongsheng Yang authored
      As the buildid is read from /sys/kernel/notes, then if we use perf kvm
      buildid-list with a perf data file captured by perf kvm record with
      --guestkallsyms and --guestmodules, there is no result in output.
      
      This patch add a explanation about it and add a limit of using perf kvm
      buildid-list.

      perf target: Move the checking of which map function to call into function. · 9c105fbc
      Dongsheng Yang authored
      Check for cpu_map__dummy_new() or cpu_map__new() to be called in
      perf_evlist__create_maps() is more complicated.
      
      This patch moves the checking work into target.h, combining two
      conditions and making perf_evlist__create_maps() more readable.
