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.

perf tools, tools lib traceevent: Rename "pevent" member of struct tep_event to "tep"

2019-04-01T18:18:10+00:00

The member "pevent" of the struct tep_event is renamed to "tep". This
makes the struct consistent with the chosen naming convention:

  tep (trace event parser), instead of the old pevent.

tools lib traceevent: Rename input arguments of libtraceevent APIs from pevent to tep

2019-04-01T18:18:09+00:00

Input arguments of libtraceevent APIs are renamed from "struct
tep_handle *pevent" to "struct tep_handle *tep". This makes the API
consistent with the chosen naming convention: tep (trace event parser),
instead of the old pevent.

tools tools, tools lib traceevent: Make traceevent APIs more consistent

2019-04-01T18:18:09+00:00

Rename some traceevent APIs for consistency:

tep_pid_is_registered() to tep_is_pid_registered()
tep_file_bigendian() to tep_is_file_bigendian()

  to make the names and return values consistent with other tep_is_... APIs

tep_data_lat_fmt() to tep_data_latency_format()

  to make the name more descriptive

tep_host_bigendian() to tep_is_bigendian()
tep_set_host_bigendian() to tep_set_local_bigendian()
tep_is_host_bigendian() to tep_is_local_bigendian()

  "host" can be confused with VMs, and "local" is about the local
  machine. All tep_is_..._bigendian(struct tep_handle *tep) APIs return
  the saved data in the tep handle, while tep_is_bigendian() returns
  the running machine's endianness.

All tep_is_... functions are modified to return bool value, instead of int.

tools lib traceevent: Rename tep_is_file_bigendian() to tep_file_bigendian()

2019-01-08T16:28:13+00:00

In order to make libtraceevent into a proper library, its API
should be straightforward.

After a discussion with Steven Rostedt, we decided to rename a few APIs,
to have more intuitive names.

This patch renames tep_is_file_bigendian() to tep_file_bigendian().

tools lib traceevent: Fix diverse typos in comments

2018-12-17T17:56:34+00:00

Go over the tools/ files that are maintained in Arnaldo's tree and
fix common typos: half of them were in comments, the other half
in JSON files.

No change in functionality intended.

Committer notes:

This was split from a larger patch as there are code that is,
additionally, maintained outside the kernel tree, so to ease cherry
picking and/or backporting, split this into multiple patches.

tools lib traceevent, perf tools: Rename 'struct tep_event_format' to 'struct tep_event'

2018-12-17T17:56:02+00:00

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts.

This renames 'struct tep_event_format' to 'struct tep_event', which
describes more closely the purpose of the struct.
