We need input from architecture maintainers about the best way to proceed to guarantee core serialization instructions within the membarrier system call (and possibly within the scheduler).

Open discussion with Real-Time Linux users, developers, and the stable RT maintainer.

user stack trace to name resolution is hard. Thankfully kernel can help

Discuss about using CTF to do BPF introspection

Presentation of upcoming Common Trace Format (CTF) 2.0, discussion of use-cases. (slides)

Talk about ways to make using BPF less awful for non-kernel hackers.

Describes current efforts to replace the out-of-tree Android xt_qtaguid kernel code with an upstream solution based on eBPF cgroup filters. (slides)

Kernel-assisted trace re-construction for JITed code

Syncless technique for tracing virtual machine on any layer (nested too) (slides)

Get LKMM installed and make use of it! (slides)

Quick overview of Linux kernel memory model: How to install and use (slides)

lessons from using kprobe text based api and proposed extensions

Quick discussion of future BPF analysis tools

Check for power/perf regressions.

Reworking the IPI logic to implement the RT (and deadline) scheduler for push/pull logic

The Linux scheduler has become fairly complex and is not always able to preserve work-conservation. We present Ipanema, a DSL to write simple and safe schedulers with proven properties. (slides)

Briefing the preliminary dyninst based study, and then discussions.

Improving event tracing, post-processing tools and scheduler models. (slides)

Correlate traces from ebpf, perf and LTTng of large systems using the Trace Compass tool

Talk about how we want to deal with trace points as a user space interface

overview and discussion of uftrace tracing both user and kernel space

Simulate workloads with rt-app

Discuss the various ways BPF can be used to categorize workloads and use it to build generic workload simulators.

Discussion on which workloads to use (or what is recommended etc) for the evaluation of CPU PM changes in the kernel.

The purpose of this talk is to describe status quo of the Live Kernel Patching implementation and identify future steps needed to improve the implementation (slides)

This talk will discuss new performance analysis capabilities and tools using enhanced BPF, including scheduler, FS, and TCP analysis, beginning a new generation of advanced tools and visualizations. (slides)

Discuss features and design of a fair, sleepable range reader/writer lock for the linux kernel. (slides)

Discussion about the open issues of the deadline scheduler. (slides)

What factors might interfere with the kernel development community's future growth? (slides)

A new interface for a new bread of User-mode filesystems that require extremely Low-Latency, synchronous, NUMA aware, DAX capable FileSystems. (slides)
