tools lib traceevent: Fix output of %llu for 64 bit values read on 32 bit machines

2016-02-24T09:23:22+00:00

commit 32abc2ede536aae52978d6c0a8944eb1df14f460 upstream.

When a long value is read on 32 bit machines for 64 bit output, the
parsing needs to change "%lu" into "%llu", as the value is read
natively.

Unfortunately, if "%llu" is already there, the code will add another "l"
to it and fail to parse it properly.

tools lib traceevent kbuffer: Remove extra update to data pointer in PADDING

2015-05-04T09:50:06+00:00

commit c5e691928bf166ac03430e957038b60adba3cf6c upstream.

When a event PADDING is hit (a deleted event that is still in the ring
buffer), translate_data() sets the length of the padding and also updates
the data pointer which is passed back to the caller.

This is unneeded because the caller also updates the data pointer with
the passed back length. translate_data() should not update the pointer,
only set the length.

tools lib traceevent: Port kbuffer parser routines

2013-07-12T16:52:16+00:00

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

2013-07-12T16:52:14+00:00

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()

2013-07-12T16:52:12+00:00

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

2013-07-12T16:52:11+00:00

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

2013-03-13T20:00:00+00:00

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.
