= 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.
Welcome to the architecture page for ARM. This covers both ARMv7 (aka armhfp and arm-32) and aarch64 (aka ARMv8 and arm-64).


The Fedora-ARM project is an initiative to bring Fedora to this processor family.
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 Server, SBCs, IoT and other usecases that are similar to the Fedora Workstation / Server / Cloud that other Fedora architectures support.


= Fedora ARM Quick Start Guide =
The Fedora software stack experience across both the 32 and 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 solely upstream kernels and don't use different kernels for each different ARM device we support.

'''OLD PAGE CONTENTS HERE'''
-- page was renamed from ARM --
 
= Fedora ARM =
 
This is the starting page for the Fedora port to the ARM architecture.
 
 
 
== Goals and Objectives ==
 
The primary goal of this project is to provide support for ARM as a [[TomCallaway/SecondaryArchitectures|  secondary architecture]]  in Fedora.
 
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 ==
 
=== Native Compilation ===
 
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.
 
=== CPU and Architecture Target ===
 
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.
 
=== Installer and Kernel ===
 
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.

To kick off a koji scratch build, run:
The best place to get help with ARM issues is on #fedora-arm on Freenode. 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 channel. You can also email the Fedora ARM mailing list for assistance.
<pre>
koji -c ~/.koji/arm-config build --scratch dist-f13 /path/to/srpm

You can change the dist tag to the dist you want to target.

Introduction

Welcome to the architecture page for ARM. This covers both ARMv7 (aka armhfp and arm-32) and aarch64 (aka ARMv8 and arm-64).

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 Server, SBCs, IoT and other usecases that are similar to the Fedora Workstation / Server / Cloud that other Fedora architectures support.

The Fedora software stack experience across both the 32 and 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 solely upstream kernels and don't use different kernels for each different ARM device we support.

Getting started

The first starting point for ARM is the ARM Installation Guide or AARCH64 F27 Installation Guide

Download

Current stable release

The current stable release for ARMv7 can always be found at the ARM Image landing page

The current stable release for aarch64 can always be found at Alternate Architectures landing page

Current development releases

There are currently two development releases. Fedora 26 is in the stabilisation phase, Fedora rawhide (27) is in the development phase.

Supported Hardware and Devices

We support a wide variety of hardware and devices from numerous Single Board Computers (SBCs) like the Raspberry Pi 2 and 3 through to Chromebooks and SBSA compliant Servers.

Here is list of device pages based on device category or SoC:

We don't directly support devices such as phones and tablets but it's not to say that without the required kernel/bootloader know how that they don't work, it's just not our primary focus.

Scratch an itch

All architectures are now integrated into the standard Fedora process. We don't diverge in any way. So without even realising 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 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 Freenode. 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 channel. You can also email the Fedora ARM mailing list for assistance.
