self nomination

Hi,

I would like to nominate myself for kernel summit this year.

I hack on various core subsystems mainly in the name of performance and am particularly interested in the following topics/discussions:

- C++11 atomics/kernel memory model.
- Upstreaming PREEMPT_RT.
- Regression tracking.
- (and to a lesser degree unit testing)

In addition, I'm wondering if there's any interest in a performance session (getting to know some of the bottlenecks that are currently making folks cry), like Chris Mason has been doing in past kernel summits for fb specific workloads.

Thanks,
Davidlohr

Hi!

I'd be interested in that session. But we need to find enough content. We can certainly talk about our experiences with updating kernel for SLE12 SP2 (to 4.4) but I don't think it would fill the whole session. So it would be good if other "vendors" shared their experiences as well.

I would be interested in these topics, too.

I guess I should nominate myself, in case either Johannes's MM topic comes up, or the above topics.

Yes, we need a performance related session. I posted a proposal but not very responsive.

I can talk about tracing and tools/perf, especially the progress of BPF. We can discuss something about performance profiling based on these tracing result.

Thank you.

Fair enough, although I was referring to something a little more tangible, such as specific pressure points and bottlenecks in (hopefully) real workloads/systems. In the past this has worked well, and some issues that have been brought to our attention have been addressed.

Like others already said, this obviously requires enough interest and content; so other performance related topics could fit as well.

Thanks,
Davidlohr
