tools lib traceevent: Update FSF postal address to be URL's.

2013-01-24T19:40:17+00:00

The FSF now prefers to use URL's in copyright headers rather than
their postal address. This change updates the address to be
 per http://www.gnu.org/licenses/gpl-howto.html

tools lib traceevent: Carve out events format parsing routine

2012-09-24T15:26:31+00:00

The pevent_parse_event() routine will parse a events/sys/tp/format file
and add an event_format instance to the pevent struct.

This patch introduces a pevent_parse_format() routine with just the bits
needed to parse the event/sys/tp/format file and just return the
event_format instance, useful for when all we want is to parse the
format file, without requiring the pevent struct.

perf tools: Use __maybe_used for unused variables

2012-09-11T15:19:15+00:00

perf defines both __used and __unused variables to use for marking
unused variables. The variable __used is defined to
__attribute__((__unused__)), which contradicts the kernel definition to
__attribute__((__used__)) for new gcc versions. On Android, __used is
also defined in system headers and this leads to warnings like: warning:
'__used__' attribute ignored

__unused is not defined in the kernel and is not a standard definition.
If __unused is included everywhere instead of __used, this leads to
conflicts with glibc headers, since glibc has a variables with this name
in its headers.

The best approach is to use __maybe_unused, the definition used in the
kernel for __attribute__((unused)). In this way there is only one
definition in perf sources (instead of 2 definitions that point to the
same thing: __used and __unused) and it works on both Linux and Android.
This patch simply replaces all instances of __used and __unused with
__maybe_unused.

tools lib traceevent: Get rid of die() from pevent_register_print_function

2012-09-07T15:15:31+00:00

If memory allocation for handler fails or argument type is not match,
return gracefully instead of calling die().  Also add an new error code
for the later case.

tools lib traceevent: Introduce pevent_strerror

2012-08-22T19:03:39+00:00

The pevent_strerror() sets @buf to a string that describes the
(libtraceevent-specific) error condition that is passed via @errnum.

This is similar to strerror_r() and does same thing if @errnum has a
standard errno value.

To sync error string with its code, define PEVENT_ERRORS with _PE()
macro and use it as suggested by Steven.

tools lib traceevent: Introduce pevent_errno

2012-08-22T19:02:59+00:00

Define and use error numbers for pevent_parse_event() and get rid of
die() and do_warning() calls. If the function returns non-zero value,
the caller can check the return code and do appropriate things.

I chose the error numbers to be negative not to clash with standard
errno, and as usual, 0 for success.

tools lib traceevent: Add support for __print_hex()

2012-06-29T16:28:12+00:00

Since the __print_hex() function is used in print fmt now, add
corresponding parser routines. This makes the output of perf script on
the kvm_emulate_insn event not to fail any more.

 before:
      kvm_emulate_insn:     [FAILED TO PARSE] rip=3238197797 ...

 after:
      kvm_emulate_insn:     0:c102fa25:89 10 (prot32)

parse-events: Rename struct record to struct pevent_record

2012-04-25T11:35:48+00:00

As libtraceevent will be a library, having struct record is far
too generic of a name to use. Renaming it to be consistent with the
rest of the functions will be a better long term solution.

perf/events: Add flag to produce nsec output

2012-04-25T11:35:18+00:00

libtraceevent library prints out in usecs but perf wants to print out
in nsecs. Add a flag that lets the user decide to print out in usec
or nsec times.
