Raspberry Pi receives strategic investment from Arm

This page summarizes the projects mentioned and recommended in the original post on news.ycombinator.com

Our great sponsors
  • WorkOS - The modern API for authentication & user identity.
  • Onboard AI - ChatGPT with full context of any GitHub repo.
  • InfluxDB - Power Real-Time Data Analytics at Scale
  • openc910

    OpenXuantie - OpenC910 Core

    For "coming down the pipeline" they're essentially free.

    Today, the c910 is an Apache 2, hardware proven out of order core on GitHub here https://github.com/T-head-Semi/openc910 a little slower than an RPi3's core.

  • rpi-open-firmware

    Open source VPU side bootloader for Raspberry Pi. (by librerpi)

    > Please correct me if I'm wrong.

    My memory told me it was the GPU that needed the blobs. So I asked at DDG

    https://duckduckgo.com/?t=ftsa&q=binary+blobs+and+the+Raspbe...

    Turned up this: https://wiki.debian.org/RaspberryPi and it says...

    > All Raspberry Pi models before the 4 (1A, 1B, 1A+, 1B+, Zero, Zero W, 2, 3, Zero 2 W) boot from their GPU (not from the CPU!), so they require a non-free binary blob to boot

    So the 4 (and I suppose the 5, if it ever actually comes...)

    Goes on to say:

    > Since then, Broadcom publicly released some code, licensed as 3-Clause BSD, to aid the making of an open source GPU driver. The "rpi-open-firmware" effort to replace the VPU firmware blob started in 2016. See more at https://news.ycombinator.com/item?id=11703842 . Unfortunately development of rpi-open-firmware is currently (2021-06) stalled.

    So there you are. Not wrong, are you, but not strictly correct, depending on "...to run properly" definition

  • WorkOS

    The modern API for authentication & user identity. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • duckduckgo-locales

  • riscv-profiles

    RISC-V Architecture Profiles

    >there are a lot of incompatible ISA implementations of RISC-V

    This is common FUD.

    In reality, most chips in the market, including all known application processors, follow the RVA profile[0] spec.

    So do Linux distributions.

  • PSn00bSDK

    The most powerful open source SDK for the PS1 (as far as open source PS1 SDKs go). Not recommended for beginner use.

    The original PlayStation's main SoC (which is incidentally about 30 years old at this point) included a trimmed down JPEG decoder [1] meant to be used for video playback. It still relied on the CPU to handle Huffman decompression [2], but it allowed that otherwise anemic 33 MHz MIPS core to push 320x240 video at 30fps.

  • Onboard AI

    ChatGPT with full context of any GitHub repo. Onboard AI learns any GitHub repo in minutes and lets you chat with it to locate functionality, understand different parts, and generate new code. Use it for free at app.getonboardai.com.
