= Introduction =
ARM chips are the most widely-produced processor family in the world; they have historically been used in cell phones and embedded applications, and are increasingly used in tablet devices and low-power-consumption servers.


The Fedora-ARM project is an initiative to bring Fedora to this processor family.

Welcome to the architecture page for ARM. Note Fedora no longer supports ARMv7 (aka armhfp, aarch32, and arm-32), only aarch64 (aka ARMv8 and arm64).

Fedora on ARM supports a wide variety of hardware from large enterprise aarch64 SBSA compliant hardware down to cheap single board computers (SBCs). We're primarily focused on Servers, SBCs, IoT, and other use cases similar to the Fedora Workstation / Server / Cloud that other Fedora architectures support.

== Development ==
The Fedora software stack experience on the 64 bit ARM architecture variants is very similar and, in most cases, identical to what you would find on any other Fedora architecture. We use a single upstream kernel for all devices. Users of hardware that supports both 32-bit and 64-bit (A53/A72/etc) environments must use aarch64 images.

== Getting started ==


<!--
The first starting point for ARM is the [[Architectures/ARM/Installation | ARM Installation Guide]].

= Fedora ARM =


This is the starting page for the Fedora port to the ARM architecture.
* The current stable release for aarch64 can be found at [https://getfedora.org/ Get Fedora]




* Platforms that should work since the F35 timeframe [[ Architectures/ARM/Fedora_Linux_35 | Fedora 35 Hardware Status ]]


== Goals and Objectives ==
=== Current development release ===


The primary goal of this project is to provide support for ARM as a [[TomCallaway/SecondaryArchitectures|  secondary architecture]]  in Fedora.
The development release is Fedora Rawhide:


A secondary goal is to enable derivative distributions based on the Fedora package collection and repository that are more suitably optimized for embedded and mobile use-cases.

== Technical Approach ==
== Supported Hardware and Devices ==


=== Native Compilation ===
We support a wide variety of hardware and devices from numerous Single Board Computers (SBCs) like the Raspberry Pi 3 and 4 to Chromebooks and SBSA compliant servers.


Fedora policy requires that packages be natively compiled. We use a cluster of ARM hardware and QEMU virtual machines to build the packages natively for ARM.

The baseline ARM CPU architecture that we have chosen to support is ARMv5TE, Little Endian, Soft-Float, EABI. We believe that this provides a nice baseline and that the pre-built packages and root file system images. You should be able to use this on many of the modern ARM CPUs, including XScale, ARM926 and ARM-11, etc.


Although we do not provide such binaries, the sources also lend themselves for building for pre-ARMv5TE hardware. The same is true for big-endian CPUs.
We don't directly support devices such as phones and tablets, but it's not to say that without the required kernel/bootloader they don't work; it's just not our primary focus.


=== Installer and Kernel ===
= Supported Hardware Addons =
* [[Architectures/ARM/i2c|i2c and devices attached to i2c]]
* [[Architectures/ARM/gpio|Using the GPIO]]


We currently do not plan to provide an installer, ISO images, or a kernel. Unlike in the x86 world, different ARM CPU families require different kernel images. Likewise, it is not entirely clear whether it makes sense to provide an installer or ISO images.

Introduction

Welcome to the architecture page for ARM. Note Fedora no longer supports ARMv7 (aka armhfp, aarch32, and arm-32), only aarch64 (aka ARMv8 and arm64).

Fedora on ARM supports a wide variety of hardware from large enterprise aarch64 SBSA compliant hardware down to cheap single board computers (SBCs). We're primarily focused on Servers, SBCs, IoT, and other use cases similar to the Fedora Workstation / Server / Cloud that other Fedora architectures support.

The Fedora software stack experience on the 64 bit ARM architecture variants is very similar and, in most cases, identical to what you would find on any other Fedora architecture. We use a single upstream kernel for all devices. Users of hardware that supports both 32-bit and 64-bit (A53/A72/etc) environments must use aarch64 images.

Getting started

The first starting point for ARM is the ARM Installation Guide.

Supported Hardware and Devices

Scratch an itch

All architectures are now integrated into the standard Fedora process. We don't diverge in any way. So without even realizing everyone is already involved. To get involved in something more specific whether that's support for particular pieces of hardware or hardware feature, a particular piece of software, to help test or to scratch an itch a good spot to start is the mailing list or IRC channel.

Bug Reporting

Bugs should be reported against their prospective packages as per the standard Fedora process. Add a blocker of "ARMTracker" which will link to our ARM architecture tracker bug. If the bug is on a pre-release version of Fedora and you feel it's release affecting it might be considered a Blocker Bug or Freeze Exception in which case it should be reported in the QA Blocker bug app.

Getting help with ARM build issues

The best place to get help with ARM issues is on #fedora-arm on Libera. The Fedora users and developers from around the world will assist when they are available but due to the many time zones, your question may not be answered right away so its best to remain in the channel. You can also email the Fedora ARM mailing list for assistance.
