tools lib traceevent: Change to SPDX License format

2020-07-06T12:02:20+00:00

Replaced COPYING with a description of how the SPDX identifiers are
used.  Added a GPL-2.0 and LGPL-2.1 license file in the new LICENSES
directory.  Then removed all the license templates from the source files
and replaced them with the corresponding SPDX identifier.

tools lib traceevent: Add builtin handler for trace_marker_raw

2020-07-06T12:01:54+00:00

When something is written into trace_marker_raw, it goes in as a binary.
But the printk_fmt() of the event that is created (raw_data)'s format
file only prints the first byte of data:

  print fmt: "id:%04x %08x", REC->id, (int)REC->buf[0]

This is not very useful if we want to see the full data output.

Implement the processing of the raw_data event like it is in the kernel.

tools lib traceevent: Move kernel_stack event handler to "function" plugin.

2020-07-06T12:01:48+00:00

The "kernel_stack" event handler does not depend on any trace-cmd
context, it can be used aside from the application. The code is moved to
libtraceevent "function" plugin.

tools lib traceevent: Add offset option for function plugin

2020-07-06T12:01:12+00:00

When the offset option is set for the function plugin enabled, it will
display the offset of the functions along with their names.  This helps
in finding exactly where a function was called by its parent.

  trace-cmd report -O parent -O offset
 [..]
        rcuc/163-1330  [163]   740.653251: function: _raw_spin_lock+0x0  <-- rcu_cpu_kthread+0x4d8

libtraceevent: Move traceevent plugins in its own subdirectory

2019-09-25T12:51:43+00:00

All traceevent plugins code is moved to tools/lib/traceevent/plugins
subdirectory. It makes traceevent implementation in trace-cmd and in
kernel tree consistent. There is no changes in the way libtraceevent and
plugins are compiled and installed.

Committer notes:

Applied fixup provided by Steven, fixing the tools/perf/Makefile.perf
target for the plugin dynamic list file. Problem noticed when cross
building to aarch64 from a Ubuntu 19.04 container.
