2021-06-01T13:03:17+00:00

This is preparation for allowing a script to set the itrace options for the session if they have not already been set. Signed-off-by: Adrian Hunter Cc: Andi Kleen Cc: Jiri Olsa Link: https://lore.kernel.org/r/20210530192308.7382-5-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo

perf scripting: Add scripting_context__update()

2021-06-01T13:03:02+00:00

Move scripting_context update to a separate function and add the arguments of ->process_event() to it. This prepares the way for adding more methods to the perf_trace_context module, by providing the context information that they will need.

perf tools: Remove perf.h from source files not needing it

2019-08-29T20:38:32+00:00

With the movement of lots of stuff out of perf.h to other headers we ended up not needing it in lots of places, remove it from those places.

perf evsel: Rename struct perf_evsel to struct evsel

2019-07-29T21:34:42+00:00

Rename struct perf_evsel to struct evsel, so we don't have a name clash when we add struct perf_evsel in libperf. Committer notes: Added fixes for arm64, provided by Jiri.

tools lib traceevent, perf tools: Rename struct pevent to struct tep_handle

2018-08-10T18:29:35+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. That prefix will be "tep_" and not "pevent_". This changes the struct pevent to struct tep_handle.

perf script: Use HAVE_LIBXXX_SUPPORT to replace NO_LIBXXX

2018-04-12T13:33:29+00:00

In Makefile.config, we define the conditional compilation variables HAVE_LIBPERL_SUPPORT and HAVE_LIBPYTHON_SUPPORT. To make the C code more consistent, this patch replaces NO_LIBPERL/NO_LIBPYTHON in C code with HAVE_LIBPERL_SUPPORT/ HAVE_LIBPYTHON_SUPPORT.
