Adopt the following functions from tools/perf: perf_evlist__enable() perf_evlist__disable() Signed-off-by:

Jiri Olsa authored
Add the following functions: perf_evlist__open() perf_evlist__close() It's a simplified version of perf's evlist__open() without the sampling id index calculations. We can try to merge it in the future when we need it in some new libperf user. Also adopt some helper evlist traversing macros. In the future we can remove them from util/evlist.h, but that requires also some other changes. Signed-off-by:

Move the following functions: evsel__enable() evsel__disable() evsel__apply_filter() to libperf with the following names: perf_evsel__enable() perf_evsel__disable() perf_evsel__apply_filter() Export only perf_evsel__enable()/disable(), keeping the perf_evsel__apply_filter() one private for the moment.

Add a perf_evsel__open() function to libperf. It's a simplified version of evsel__open() without the fallback mechanism. We can try to merge it in the future to libperf, but it has many details, lets start simple, requiring the latest kernel, perf should continue using its evsel__open() version, continuing to support running on older kernels when possible.

And this even fixes the build in some systems where things are used somewhere down the include path from perf_event.h without defining __always_inline. Signed-off-by: -

Add perf_thread_map struct to libperf. It's added as a declaration into into: include/perf/threadmap.h which will be included by users. The perf_thread_map struct definition is added into: include/internal/threadmap.h which is not to be included by users, but shared within perf and libperf. We tried the total separation of the perf_thread_map struct in libperf, but it lead to complications and much bigger changes in perf code, so we decided to share the declaration. Signed-off-by:
