Status of OpenPOWER support in coreboot
The presentation describes efforts of porting OpenPOWER architecture firmware to open source firmware framework - coreboot. Although OpenPOWER firmware has been open-sourced some time ago, it may still benefit by implementing the support in coreboot. The differences and benefits of the OpenPOWER firmware and coreboot will be mentioned as well as current progress of work and challenges faced during development.
The IBM POWERPC architecture exists since early 90. Many may also know that the POWER processors were used in Apple Macintosh between 1994-2006. Today the IBM goes forward with their POWER processors releasing newer and newer processor
families like POWER9 and even POWER10 recently. Modern POWER architecture features very high computing performance with multi-core processors which makes them ideal for servers and computing clusters. They also are great as a workstation, for example Raptor Computing Systems Talos II (POWER9), which is the reference platform used during the coreboot port. A huge advantage of OpenPOWER architecture is its openness. Compared to modern x86 architecture which is full of binary blobs, POWER can easily rival with x86 domination and dethrone it from the most common used processors architecture in modern computers. Although the OpenPOWER firmware and documentation is open-source the development of coreboot for POWER9 is very challenging and full of unknowns. In this presentation you will hear about the current progress of the work on coreboot POWER9 support, what problems we face and how much effort it takes to enable new architecture in coreboot.

This will be an introduction to the OpenPOWER DevRoom, it will briefly explain the OpenPOWER Foundation, the changes we're making and how we want to interact more with the open source communities, for both hardware and software. And introduce the DevRoom for the day.

Microwatt is an open-source POWER CPU implementation which can run on cheap FPGAs, bringing new level of accessibility to POWER. In the last year, we have added to Microwatt features such as a memory management unit, privilege modes, interrupts, a floating-point unit, an interrupt controller and a level-2 cache, so that now it can boot Linux. This presentation will outline these new additions to Microwatt and talk about some interesting applications for Microwatt.

The LibreSOC Project is a hybrid 3D CPU, GPU and VPU, designed for use in mass-volume products such as smartphones netbooks tablets and Industrial SBC IoT. As such, user trust and reduced product development costs are both equally important. Both these goal are achieved by providing full source right to the bedrock (Hardware HDL, bootloader, drivers, everything) and deploying strict transparent "Libre" development criteria. The project has EUR 350,000 funding from NLnet under their PET Programme ...

The game has changed, FOSS OS and software is everywhere running on every CPU architectures and devices. Even mass consumer computer manufactures are producing with "new" CPU architectures. In 2020 thanks to the Open Power ISA have opened Power Architecture new Chips. It's the right time to have (back) Power Architecture for Open Source Hardware lovers, in educations, makers, hobbyists, consumers and gaming electronics. We will see concretes present projects and future options.

Void's POWER architecture port has been progressing steadily since the last OpenPOWER Summit EU talk in 2019. Recently we introduced a completely new 32-bit little endian port, which will be a big part of this talk's focus, and is a first among Linux distributions. I will not stay there though - we have more to cover, including stuff like Chromium and Electron applications in repos, faster POWER crypto in LibreSSL, reworked crosstoolchains, stable support for newest AMD GPUs, and our big endian ...

The LibreSOC hybrid 3D CPU-VPU-GPU is intended to provide a significant reduction in both hardware complexity, software (driver) complexity and systems integration primarily initially for embedded and mobile environments. Larrabee or more specifically Nyuzi showed that a software-only "Traditional Vector Processor" architecture makes for a fantastic High Performance Compute Engine that, unfortunately, also turns out to have only 25% the performance/watt of current competitive embedded mobile ...
