tools lib traceevent: Port kbuffer parser routines

2013-07-12T16:52:16Z

kbuffer code is for parsing ftrace ring-buffer binary data and used for trace-cmd. Move the code here in order to be used more widely.

tools lib traceevent: Add page_size field to pevent

2013-07-12T16:52:14Z

The page size of traced system can be different than current system's because the recorded data file might be analyzed in a different machine. In this case we should use original page size of traced system when accessing the data file, so this information needs to be saved.

tools lib traceevent: Add trace_seq_reset()

2013-07-12T16:52:12Z

Sometimes it'd be useful if existing trace_seq can be reused. But currently it's impossible since there's no API to reset the trace_seq. Let's add trace_seq_reset() for this case.

tools lib traceevent: Add const qualifier to string arguments

2013-07-12T16:52:11Z

If pevent_register_event_handler() received a string literal as @sys_name or @event_name parameter, it emitted a warning about const qualifier removal. Since they're not modified in the function we can make it have const qualifier.

libtraceevent: Remove hard coded include to /usr/local/include in Makefile

2013-03-13T20:00:00Z

having /usr/local/include hardcoded into the makefile is not necessary as this is automatically included by GCC. It also infects cross-compile builds with the host systems includes.

tools lib traceevent: Handle dynamic array's element size properly

2013-01-25T15:49:28Z

Fixing the dynamic array format field parsing. Currently the event_read_fields function could segfault while parsing dynamic array other than string type. The reason is the event->pevent does not need to be set and gets dereferenced unconditionaly. Also adding proper initialization of field->elementsize based on the parsed dynamic type.

perf tools: Reinstate 'signed' field flag for tracepoints

2013-01-24T19:40:52Z

For some reason the libtraceevent tracepoint-parsing code is missing the FIELD_IS_SIGNED flag-setting code, which causes problems for the Perl trace event binding at least, since it ends up unable to recognize negative numbers. Things like checking for negative return values therefore fail, causing scripts like rwtop to instead interpret the negative return value as a large positive value, which in turn get added to e.g. read totals with insanely invalid results. So set the FIELD_IS_SIGNED flag for tracepoint events that specify "signed:1".
