[v2,0/9] Build trace-cruncher as Python pakage

Message

Yordan Karadzhov June 11, 2021, 11:39 a.m. UTC

This patch-set restructures the project and makes it build as a native
Python package. Although it looks like a complete rewrite, this is
essentially just a switching from using Cython to using directly the C API
of Python. Cython is still being used but only for the implementation
of the NumPy data wrapper. The functionalities that are wrapping Ftrace
are extended substantially. This is possible due to switching to use of
the recently released libraries: libtraceevent and libtracefs. 

Changes in v2:
 - Addressing the comments made by Steven in his review.

 - Start using the libtracefs APIs for enable/disable events.

 - Add functionalities for enable/disable event filters.
