OpenBMC introduction and porting guide

    ​​OpenBMC is an Open Source Software project started in an effort to create a secure, scalable, open source firmware code for BMC. Apart from the usual benefits arising from Open Source nature, OpenBMC brings in additional advantages like a.) state-of-the-art build system based on Yocto - an embedded linux distribution - which simplifies the process of building customized Linux, b.) Robust Managebility framework based on (4 pillars - REST, JSON, HTTPS, ODATAv4) RedFish, c.) Superior Modularity with D-bus IPC mechanism which is known for its well defined interfaces, d.) Ability to customize the code, e.) Support for IPMI, etc. In this video, I will show you: 1. OpenBMC introduction 2. Yocto & Systemd concepts 3. Demo of building your first OpenBMC image in toaster environment and running it in QEMU, 4. Short-demo of OpenBMC porting to new platform using JSON files. Porting OpenBMC to new platforms becomes easy with easily customizable JSON files representing the platforms entities like baseboard, PSU, chassis, etc. i.e.) Platform entities are abstracted as JSON files, and sensors properties of each entity is represented as JSON key-value pairs. This can help any one having little or no experience in OpenBMC to easily port it to new platforms in quick time.

This is the continuation of the "Status of AMD platform in coreboot" presented last year on the Open Source Firmware, BMC and Bootloader devroom. The talk will cover the news around the AMD support in Open Source Firmware ecosystem from the past year. You will hear, among others, about: FSF RYF KGPE-D16 platform revival, AMD Ryzen R1000/V1000 series AGESA integration into open source TianoCore EDK2, TrenchBoot new features and updates and current support of AMD Picasso and Cezanne SoCs in ...

During that presentation I will run a quick demo of the OSFCI infrastructure which is developed by HPE to validate and build Open Source Firmware stack on Proliant server. I will introduce an overview at how the code works, and how to get involve, and make scale the platform. This project is available on github. https://github.com/hewlettpackard/osfci

With the advancement of open source firmware projects, we need a reliable quality assurance process to automate the firmware level testing. In this talk I'd like to show how we build up a ecosystem for open-source firmware testing and show by example how we integrated one project into that ecosystem. This talk aims to give a status update what has been show on the OSFC2020, and also encourage people to get involved and participate in open-source firmware testing. All code shown is open-source ...

RISC-V is a relatively new ISA and platform, which has been evolving rapidly. A few Linux distributions already have good support and have compiled most of their packages for it. The boot process has been neglected and only recently did everyone start using the widely used embedded bootloader U-Boot instead of a custom research bootloader. We have ported the EDK2 reference implementation of UEFI to make the boot process more like current desktops and servers. This talk explains how we did that, ...

Utilizing secure boot should be simple. Our current tooling is badly integrated, abstractions leaking and the code bases are not reusable. Functionality is spread between several projects and not one covers all your needs. This amounts to a confusing landscape. sbctl and go-uefi is a tool, and a low-level UEFI library, that attempts to push the secure boot landscape forward.

There is existing work in the public space on how to correctly construct a DRTM launch but not an equivalent amount on how to maintain the integrity of the DRTM launch over the lifecycle of a system. In particular a specific area of concern is how to correctly construct a secure upgrade for the DRTM launch that minimizes the risk of the process being corrupted. There are a few challenges that must be overcome and in this presentation these will be covered along with a novel approach that will ...

Ampere Computing is a relatively new entrant into the server space, recently launching its 80-core ARM64 Altra processor on the Mt. Jade platform. In this talk, I'll cover the status of various open-source projects such as EDK2, LinuxBoot, OpenBMC and OpenOCD on Ampere's processors and platforms. For those interested in learning more about Ampere and our engagement in open-source firmware, this is the talk for you.
