      tools lib traceevent: Report better error message on bad function args · 3a3ffa2e
      由 Steven Rostedt 提交于 
      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

      perf trace: Fix summary percentage when processing files · 3160565f
      由 David Ahern 提交于 
      Getting a divide by 0 when events are processed from a file:

   perf trace -i perf.data -s
   ...
   dnsmasq (1684), 10 events, inf%, 0.000 msec

The problem is that the event count is not incremented as events are
processed. With this patch:

   perf trace -i perf.data -s
   ...
   dnsmasq (1684), 10 events, 8.9%, 0.000 msec

      perf trace: Add support for syscalls vs raw_syscalls · 9aca7f17
      由 David Ahern 提交于 
      Older kernels (e.g., RHEL6) do system call tracing via
syscalls:sys_{enter,exit} rather than raw_syscalls. Update perf-trace to
detect lack of raw_syscalls support and try syscalls.

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
     kvm:kvm_nested_vmexit
     kvm:kvm_nested_vmexit_inject

      perf tools: Overload pr_stat traceevent print function · f772abc6
      由 Jiri Olsa 提交于 
      The traceevent lib uses pr_stat to display all standard info. It's
defined as __weak. Overloading it with perf version plugged into perf
output system logic.

Displaying the pr_stat stuff under '-v' option.

      perf tools: Add trace-event global object for tracepoint interface · 97978b3e
      由 Jiri Olsa 提交于 
      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.

      Add trace-event object to keep together 'struct pevent' object with its
loaded plugins with following interface:

int trace_event__init(struct trace_event *t);

  - Initalizes 'struct pevent' object and loads plugins for it

void trace_event__cleanup(struct trace_event *t);

  - Cleanups both 'struct pevent' and plugins

      由 Jiri Olsa 提交于 
      Adding filename__read_str util function to read
text file and return it in the char array.

The interface is:
  int filename__read_str(const char *filename, char **buf, size_t *sizep)

  Returns 0/-1 if the read suceeded/fail respectively.

  buf  - place to store the data pointer
  size - place to store data size

v2 change:
  - better error handling suggested by Namhyung Kim.

      由 Jiri Olsa 提交于 
      Adding 'plugins' target along with the libtraceevent.a, so plugins are
built together with traceevent library.

Adding 'install-traceevent-plugins' Makefile install target, instructing
perf to install plugins into:

  $(HOME)/.traceevent/plugins

  $(DESTDIR)/$(prefix)/$(libdir)/traceevent/plugins

  $ make install

      tools lib traceevent: Change pevent_parse_format to include pevent handle · 71ad9583
      由 Jiri Olsa 提交于 
      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.
