Software Tools Bootcamp RISC-V ISA Tutorial — HPCA-21 08 February 2015 Albert Ou UC Berkeley [email protected] Preliminaries To follow along, download these slides at http://riscv.org/tutorial-hpca2015.html 2 Preliminaries . Shell commands are prefixed by a “$” prompt. Due to time constraints, we will not be building everything from source in real-time. - Binaries have been prepared for you in the VM image. - Detailed build steps are documented here for completeness but are not necessary if using the VM. Interactive portions of this tutorial are denoted with: $ echo 'Hello world' . Also as a reminder, these slides are marked with an icon in the upper-right corner: 3 Software Stack . Many possible combinations (and growing) . But here we will focus on the most common workflows for RISC-V software development 4 Agenda 1. riscv-tools infrastructure 2. First Steps 3.

With Yocto/Openembedded
PORTING NEW CODE TO RISC-V WITH YOCTO/OPENEMBEDDED Martin Maas ([email protected]) 1st RISC-V Workshop, January 15, 2015 Monterey, CA WHY WE NEED A LINUX DISTRIBUTION • To build an application for RISC-V, you need to: – Download and build the RISC-V toolchain + Linux – Download, patch and build application + dependencies – Create an image and run it in QEMU or on hardware • Problems with this approach: – Error-prone: Easy to corrupt FS or get a step wrong – Reproducibility: Others can’t easily reuse your work – Rigidity: If a dependency changes, need to do it all over • We need a Linux distribution! – Automatic build process with dependency tracking – Ability to distribute binary packages and SDKs 2 RISCV-POKY: A PORT OF THE YOCTO PROJECT • We ported the Yocto Project – Official Linux Foundation Workgroup, supported by a large number of industry partners – Part I: Collection of hundreds of recipes (scripts that describe how to build packages for different platforms), shared with OpenEmbedded project – Part II: Bitbake, a parallel build system that takes recipes and fetches, patches, cross-compiles and produces packages (RPM/DEB), images, SDKs, etc. • Focus on build process and customizability 3 GETTING STARTED WITH RISCV-POKY • Let’s build a full Linux system including the GCC toolchain, Linux, QEMU + a large set of packages (including bash, ssh, python, perl, apt, wget,…) • Step I: Clone riscv-poky: git clone [email protected]:ucb-bar/riscv-poky.git • Step II: Set up the build system: source oe-init-build-env • Step III: Build an image (may -
Functional Package and Configuration Management with GNU Guix
Functional Package and Configuration Management with GNU Guix David Thompson Wednesday, January 20th, 2016 About me GNU project volunteer GNU Guile user and contributor since 2012 GNU Guix contributor since 2013 Day job: Ruby + JavaScript web development / “DevOps” 2 Overview • Problems with application packaging and deployment • Intro to functional package and configuration management • Towards the future • How you can help 3 User autonomy and control It is becoming increasingly difficult to have control over your own computing: • GNU/Linux package managers not meeting user needs • Self-hosting web applications requires too much time and effort • Growing number of projects recommend installation via curl | sudo bash 1 or otherwise avoid using system package managers • Users unable to verify that a given binary corresponds to the source code 1http://curlpipesh.tumblr.com/ 4 User autonomy and control “Debian and other distributions are going to be that thing you run Docker on, little more.” 2 2“ownCloud and distribution packaging” http://lwn.net/Articles/670566/ 5 User autonomy and control This is very bad for desktop users and system administrators alike. We must regain control! 6 What’s wrong with Apt/Yum/Pacman/etc.? Global state (/usr) that prevents multiple versions of a package from coexisting. Non-atomic installation, removal, upgrade of software. No way to roll back. Nondeterminstic package builds and maintainer-uploaded binaries. (though this is changing!) Reliance on pre-built binaries provided by a single point of trust. Requires superuser privileges. 7 The problem is bigger Proliferation of language-specific package managers and binary bundles that complicate secure system maintenance. -
ROOT Package Management: “Lazy Install” Approach
ROOT package management: “lazy install” approach Oksana Shadura ROOT Monday meeting Outline ● How we can improve artifact management (“lazy-install”) system for ROOT ● How to organise dependency management for ROOT ● Improvements to ROOT CMake build system ● Use cases for installing artifacts in the same ROOT session Goals ● Familiarize ROOT team with our planned work ● Explain key misunderstandings ● Give a technical overview of root-get ● Explain how root-get and cmake can work in synergy Non Goals We are not planning to replace CMake No change to the default build system of ROOT No duplication of functionality We are planning to “fill empty holes” for CMake General overview Manifest - why we need it? ● Easy to write ● Easy to parse, while CMakeLists.txt is impossible to parse ● Collect information from ROOT’s dependencies + from “builtin dependencies” + OS dependencies + external packages to be plugged in ROOT (to be resolved after using DAG) ● It can be easily exported back as a CMakeLists.txt ● It can have extra data elements [not only what is in CMakeLists.txt, but store extra info] ○ Dependencies description (github links, semantic versioning) ■ url: "ssh://[email protected]/Greeter.git", ■ versions: Version(1,0,0)..<Version(2,0,0) Manifest is a “dump” of status of build system (BS), where root-get is just a helper for BS Manifest - Sample Usage scenarios and benefits of manifest files: LLVM/Clang LLVM use CMake as a LLVMBuild utility that organize LLVM in a hierarchy of manifest files of components to be used by build system llvm-build, that is responsible for loading, verifying, and manipulating the project's component data.
