Accelerated data processing using FPGA
The FPGA technology is becoming more available in recent years, yet the learning curve stays very steep. In this talk, Marek will explain what the FPGAs are and how they can be used to help with heavy computational tasks.

The beginning of the talk provides a brief introduction of the FPGA technology and the necessary tools. In the rest of the presentation, Marek will talk about methods and their pros and cons of offloading heavy tasks into the FPGA. Finally, Marek will also cover emerging technologies which might make programming the FPGA easiler and less prone to errors, like OpenCL, C2H, Chisel.

Linux Device Model
An introduction to the implementation of the linux device model. How buses, devices, drivers, classes and modules are organized and communicates with each other inside the kernel, the role of kobjects and ksets. How sysfs is organized to give to the user an overview of this organization, and how to understand the contents of sysfs.

RealTime KVM
KVM now supports real-time. This allows for virtualizing workloads with low and deterministic latency requirements. KVM real-time is one of the building blocks needed by NFV (Network Function Virtualization).

This talk will introduce the real-time topic to the public, walk through the kernel and KVM improvements we did upstream and discuss real-time KVM host and guest configuration.

What's up in the Kernel Land
This presentation gives an overview of recent and current developments in the Linux kernel; it will discuss what major changes the recent kernel versions brought, what the next kernel version will bring and what the kernel developers are working on for future releases. In that scope the presentation sometimes will also discuss changes in software close to the kernel; that for example includes Mesa, as its OpenGL hardware drivers work closely with the graphics drivers in the Linux kernel.

Introduction to Linux Kernel Crash Analysis
As a Technical Support Engineer on the Kernel team, one of the top tools I need is kdump and crash, both used to determine the cause of a kernel crash.
In this presentation, I want to give an introduction on how kdump works and how it generates vmcores and how people can use crash to debug vmcores generated by kernel crashes.
I will demo some basic scenarios where kdump is useful and, if time permits, some more advanced debugging techniques.

Patch, compile and boot your first kernel
The structure of kernel source and the process of kernel boot will be explained at the beginning of the workshop. Afterwards, participants of this workshop will have a chance to try to experiment with modifying of upstream kernel source, configuring it, compiling it and boot the resulting kernel on their own laptops.
Estimated length: 50-60minutes.
