Stefan Agner 8e1016dcaf Initial Raspberry Pi 5 support (#2914)
* Add initial Raspberry Pi 5 buildroot config

* Add machine-id support via cmdline.txt

* Add new entry if entry is missing

* Don't overwrite cmdline.txt when adding machine-id

Use sed to append the new cmdline parameter to the first line.

* Skeleton script for RAUC custom bootloader interface

* Deploy kernel/device-tree into a RAUC slot specific directory

This allows us to use the os_prefix feature to switch between slot A and
B. Compared to the boot_partition option, this option allows to use a
shared config.txt and cmdline.txt, which makes it more like how HAOS
currently works on other Raspberry Pis.

* Deploy new kernel/device-tree to correct slot on installation

* Increase boot size to 128MB

This makes sure we can store up to three kernels (slot A, B and an
temporary one while installing the OTA update).

* Initial tryboot implementation using os_prefix

* Make sure to delete the old slot completely

* Add Busybox xargs for tryboot bootloader script

* Compare tryboot bootloader file silently

* Revert "Increase boot size to 128MB"

This reverts commit 7f2c69b58f02f500d6aeee4f0a419046899b5e38.

* Use compressed kernel

* Address shellcheck

* Address shellcheck issue in rauc-hook

* Fix shellcheck for rpi-tryboot.sh

* Do not follow source - it gets checked separately

* Correctly set the slot to boot

* Apply suggestions from code review

* Drop serial console from default cmdline.txt

* Resync rpi5_64_defconfig with rpi4_64_defconfig

* Improve machine-id match

Only match actual hexadecimal characters.

* Deploy firmware overlays to OS prefix directory

* Add Raspberry Pi 5 to documentation

* Bump buildroot

* buildroot fd1dc86f40...f13ad03408 (1):
  > linux: add in-tree device tree overlay support

* Install device tree overlays from Kernel sources

* Drop RPi RF modules for now

No Raspberry Pi 5 specific device tree overlays are  available, drop RPi
RF mod for now.

* Use Raspberry 5 specific identifiers for Supervisor/OS Agent

* Bump buildroot

* buildroot f13ad03408...07e08e01b2 (1):
  > linux: fix add in-tree device tree overlay support

* Revert "Drop RPi RF modules for now"

This reverts commit 46fc1701e4.

Home Assistant Operating System

Home Assistant Operating System (formerly HassOS) is a Linux based operating system optimized to host Home Assistant and its Add-ons.

Home Assistant Operating System uses Docker as its container engine. By default it deploys the Home Assistant Supervisor as a container. Home Assistant Supervisor in turn uses the Docker container engine to control Home Assistant Core and Add-Ons in separate containers. Home Assistant Operating System is not based on a regular Linux distribution like Ubuntu. It is built using Buildroot and it is optimized to run Home Assistant. It targets single board compute (SBC) devices like the Raspberry Pi or ODROID but also supports x86-64 systems with UEFI.

Features

  • Lightweight and memory-efficient
  • Minimized I/O
  • Over The Air (OTA) updates
  • Offline updates
  • Modular using Docker container engine

Supported hardware

  • Raspberry Pi
  • Hardkernel ODROID
  • Asus Tinker Board
  • Generic x86-64 (e.g. Intel NUC)
  • Virtual appliances

See the full list and specific models here

Getting Started

If you just want to use Home Assistant the official getting started guide and installation instructions take you through how to download Home Assistant Operating System and get it running on your machine.

If you're interested in finding out more about Home Assistant Operating System and how it works read on...

Development

If you don't have experience with embedded systems, Buildroot or the build process for Linux distributions it is recommended to read up on these topics first (e.g. Bootlin has excellent resources).

The Home Assistant Operating System documentation can be found on the Home Assistant Developer Docs website.

Components

  • Bootloader:
    • Barebox for devices that support UEFI
    • U-Boot for devices that don't support UEFI
  • Operating System:
  • File Systems:
    • SquashFS for read-only file systems (using LZ4 compression)
    • ZRAM for /tmp, /var and swap (using LZ4 compression)
  • Container Platform:
    • Docker Engine for running Home Assistant components in containers
  • Updates:
    • RAUC for Over The Air (OTA) and USB updates
  • Security:

Development builds

The Development build GitHub Action Workflow is a manually triggered workflow which creates Home Assistant OS development builds. The development builds are available at https://os-artifacts.home-assistant.io/index.html.
