SAN19-410 CoreSight: New Features and Ongoing Development

This presentation will start by going over the latest features that have been added to the CoreSight subsystem in the last 6
months.

From there we will provide a brief recap of the hardware capabilities of the CoreSight Embedded Cross Trigger infrastructure and introduce the newly created Cross Trigger Interface (CTI) driver and programming API. We will also provide some use cases and programming examples.

Lastly we will present an outline of the proposed CoreSight Complex Configuration framework, a set of tools and driver updates to allow users to extract the full capabilities out of CoreSight infrastructure with a simple client interface.

SAN19-416 Transforming kernel developer workflows with CI/CD

26 million lines of code. 750,000 commits. 61,000 files. "Continuous integration and deployment of the Linux kernel is impossible", they said. We believe it's definitely within reach.

The Continuous Kernel Integration (CKI) project wants to fundamentally change the kernel developer workflow by adding continuous integration and continuous deployment (CI/CD). In this talk, the audience will embark on a journey of triumph and tragedy through the experiences of a small team at Red Hat.

Major Hayden, principal software engineer at Red Hat, will explain how kernels are built and tested within the CKI infrastructure and what testing is already in place today. He will take a deep dive into the infrastructure components (including Gitlab, Jenkins, and containers) and the optimizations that allow for rapid testing of the Linux kernel. Members of the audience will also learn how they can get involved in the project.

SAN19-424 Event Tracing and Pstore with a pinch of Dynamic debug

Event tracing is one of the powerful debug feature available in Linux Kernel as part of Ftrace. Pstore or Persistent Storage on the other hand is a boon to find the cause for the kernel's dying breath as rightly said by someone and is widely used in production environments. When these two features are combined with a pinch of Dynamic debug, we form a full recipe for debugging problems in Linux Kernel.

This presentation talks about integrating event tracing with pstore to identify and root cause problems by analyzing the last few events before the Kernel says goodbye. In addition to this, we add dynamic debug support to filter out unwanted logs and limit trace to only specific files or directories which help in narrowing down problems to specific subsystems and currently is not supported by Ftrace.
