FOSDEM 2019 Open Source Developers Meeting Schedule

FOSDEM – which stands for Free and Open Source Software Developers’ European Meeting – is a free-to-participate event where developers meet on the first week-end of February to discuss open source software & hardware projects.

FOSDEM 2019 will take place on February 2 & 3, and the schedule has already been published with 671 speakers scheduled to speak in 711 events themselves sorted in 62 tracks. Like every year, I’ll create a virtual schedule based on some of the sessions most relevant to this blog in tracks such as  open hardware, open media, RISC-V, and hardware enablement tracks.

February 2

• 10:30 – 10:55 – VkRunner: a Vulkan shader test tool by Neil Roberts

A presentation of VkRunner which is a tool to help test the compiler in your Vulkan driver using simple high-level scripts.

Perhaps the largest part of developing a modern graphics driver revolves around getting the compiler to generate the correct code. In order to achieve this, extensive testing is essential. For OpenGL we have Piglit and its convenient shader_runner script format. On Vulkan, writing the boilerplate needed to test a simple shader is a lot more work. This is where VkRunner steps in to implement all of the boilerplate once and provide a very high-level scripting language to make it easy to write a test. The scripts contain the required shaders, any data they need to run and simple commands to draw or compute and probe the results.

• 11:00 – 11:25 – The final release of Kodi v18 by Martijn Kaijser

Kodi v18 has been in development for over two and finally it is released. During this presentation we go through the most important parts that were added or changed and what this actually means for the future.During past two years developers in and outside of the Kodi Team have been steadily refactoring and working on new features that will be included in Kodi v18. Although we initially thought about doing a RERO release it ended up being quite the opposite. In this presentation we will go through the most important parts that are actually included and why it took so long to come to a final release. Additionally we will briefly cover some parts that we already know will go into v19 at the moment we branched of the current v18 release.

• 11:30 – 12:30 – Porting Debian to the RISC-V architecture by K. Merker

The talk tells the story of how the Debian GNU/Linux port for the RISC-V architecture came to life and describes the steps and challenges involved in adding support for a completely new architecture to one of the major Linux distributions. It provides an overview of the current state of the port and gives an outlook on further developments.

• 12:35 – 12:55 – Embedded FreeBSD on a five-core RISC-V processor using LLVM by Jeremy Bennett

In this talk we describe our experience of bringing up embedded FreeBSD for a heterogeneous 32/64-bit RISC-V system using LLVM, which was more difficult than you might expect. We look at the practical engineering steps needed to bring up an embedded operating system where many of the key components are not fully mature. The result is a reference embedded FreeBSD implementation for RISC-V, freely available to the community.

In this talk we’ll go through the steps needed to bring up a functioning embedded FreeBSD system on multi-core heterogeneous RISC-V system. Our target hardware was not available at the start of the project, so we used the generally available HiFive Freedom Unleashed board. The result is a reference embedded FreeBSD implementation for RISC-V, freely available to the community.

• 13:00 – 13:20 – Writing Network Drivers in High-Level Languages by Paul Emmerich

Drivers are usually written in C for historical reasons, this can be bad if you want your driver to be safe and secure. We show that it is possible to write low-level drivers for PCIe devices in modern high-level languages. We are working on super-fast user space network drivers for the Intel 82599ES (ixgbe) 10 Gbit/s NIC in Rust, C#, go, OCaml, Haskell, Python, Swift, and a few more languages (WIP). All of our drivers are written from scratch and require no additional kernel code.

Check out the GitHub page with links to all implementations, performance measurements, and publications for further reading.

• 13:30 – 14:00 – The New Internet, let’s talk about IPFS by Paula

Step by step, internet as we know it is currently being limited, censored and monitored. To prevent and fight against this, there are associations, activists and such… and one of the proposals is… IPFS protocol. IPFS is, as the official website describes “peer-to-peer hypermedia protocol to make the web faster, safer, and more open”. It wants to offer a distributed alternative protocol, making it more resilient which is handy in case of developing countries, for example.

• 14:00 – 14:25 – Making Open Source Hardware for Retrogaming on Raspberry Pi by Leon Anavi

In this presentation you will learn how to use cutting edge free and open source technologies such as KiCAD and OpenSCAD to create a gamepad as a Raspberry Pi HAT (Hardware Attached on Top) with device-tree fragment for mapping the keys saved in an EEPROM connected via I2C. Exact steps for setting it up and playing retro games in emulators on RetroPie and Raspbian will be provided. Furthermore we will discuss the benefits of the open source hardware and the certification program of Open Source Hardware Association (OSHWA).

• 14:45 – 15:15 – FreeRTOS on RISC-V by Richard Barry

The open source (now MIT licensed) FreeRTOS kernel has been helping embedded developers manage the complexity of their microcontroller designs for 15 years – during which time FreeRTOS has gained a reputation for reliability, ease of use, and responsive support. FreeRTOS now runs on RISC-V!

In this talk you will see how easy it it to execute the FreeRTOS kernel in open source RISC-V emulators and on physical RISC-V microcontrollers, as well as learn how to port the FreeRTOS kernel to new RISC-V implementations.

Thanks to sndio, this NAS is connected to a Cambridge Audio DAC and an HIFI audio system.

• 17:00 – 17:50 – The TPM2 software community by Philip Tricca

Security is and has been a hot topic in recent history. Software and hardware systems are increasingly complex, vulnerabilities increasingly publicized and attack methodologies increasingly sophisticated. This trend began long ago as did efforts to design and implement foundational technologies to curtail it. The trusted platform module (TPM) is one such technology. It was specifically designed to thwart attacks that aim to steal or misuse sensitive cryptographic keys. Despite its obvious benefits, TPM adoption on OSS platforms was historically minimal.

The next iteration of TPM implementations (TPM2) is quickly reaching critical mass in consumer computing platforms. Aiming to capitalize on the availability of TPM2 hardware, the tpm2-software organization on Github has coalesced as a community around the implementation of the TCG standard APIs, and their integration into common software tool and infrastructure.

This talk will start with an overview of the tpm2-software community, it’s history, it’s current direction and how new users can get involved. The talk will then shift to discuss the technical details of the TPM2 software stack (TSS2) infrastructure and programming APIs and our current efforts to improve the security properties of OSS through their adoption. Finally, we’ll conclude by presenting a use case driving the implementation of a new TPM2 Command Transmission Interface (TCTI) module enabling use of the TPM2 from with the SGX trusted execution environment.

• 18:00 – 18:30 – Buildroot for RISC-V by Mark Corbin

Buildroot is an embedded Linux build system that generates complete system images from source for a wide range of boards and processors. I have recently added support for 64-bit RISC-V to the official Buildroot distribution which make it a viable alternative to other build systems for RISC-V such as Yocto.During this presentation I will give a brief overview of Buildroot and how it compares to Yocto for those in the audience who are unfamiliar with these systems. In the main part of the talk I will look at the issues relating to the implementation of RISC-V support, based on my experiences. This will include a look at the status of the RISC-V software ecosystem with regard to the selection of a suitable toolchain, C library, kernel and bootloader. I will then run through how to configure and build a minimal system for booting under QEMU. Finally I will consider any further work required to improve Buildroot for RISC-V including the status of 32-bit support.

• 12:00 – 12:25 – Fritzing – the past, the present and the future by Patrick Franken

Making electronics accessible to the broad public was mainly made possible by Arduino, the Raspberry PI and last but not least Fritzing. Back in 2009 it was a pain to get from a loose wiring on a breadboard to a PCB. Fritzing came up first with a unique breadboard view and a simple to use PCB layout. Fast forward 10 years Fritzing is still widely used by over 200.000 users but struggles to find a sustainable way to fund its development.

This talk will give a rough introduction to Fritzing including its strength and weaknesses and introduce a roadmap for its further development.

• 16:30 – 17:00 – FST-01SZ (Flying Stone Tiny 01 revision ShenZhen) by Yutaka Niibe

Gnuk Token is a security hardware USB token for GnuPG, which supports OpenPGP card protocol. The important feature is it avoids special thing like hardware accelerator or tool (which comes with NDA). Development environment, Tools, Firmware, and hardware design are all free, as they should be.

FST-01 was designed and used as a reference hardware implementation for Gnuk. In 2011, FST-01 was designed as free hardware design with KiCAD, so that people can use Gnuk Token for their computing, having the nature of reproducible by other parties. In 2016, we had a revision called FST-01G, following update of KiCAD. FST-01 and FST-01G were mass produced and sold more than 1200 pieces (2012-2018). In 2018, it has major update, now called FST-01SZ, using Chinese chip (GD32F103TB) and Chinese connector for USB, following another update of KiCAD. In this short talk, I will show my experience of FST-01/FST-01G/FST-01SZ, focusing new revision.

As usual FOSDEM 2019 will be free to attend, and no advanced registration is needed, you can just show up anytime during the event taking place at the ULB Solbosch Campus, Brussels, Belgium.
