Nope, you're not. Doing that we erode your patchset a bit, reducing its
One related experience I'm doing now is to have a perf.so python
binding, the setup.py file for it with the list of files needed for this
specific binding is at:
A simple tool using the resulting binding is a thread
fork/comm/exit/sample watcher, available at:
In this process I'm moving functions around so as to reduce the number
of tools/perf/util.c files to link into this perf.so python binding,
untangling things as much as possible.
The binding proper is:
I'm digressing, but twatch is an example of a simple "daemon" consuming
perf events where performance is not much of a problem.
And provides a prototyping ground when starting to design perf events
consuming daemons :-)
