Fedora 17 for Power was announced on June 14th, 2012. Please see [https://fedoraproject.org/wiki/Fedora_17_PPC_release_notes the release notes] for additional details or download it from your closest [https://mirrors.fedoraproject.org/publiclist/Fedora/17/ppc64/ mirror]. It has been most extensively tested on IBM Power systems, but is also known to work on Apple Mac G5 systems.
 
== Fedora 16 ==
 
'''Fedora 16 for PPC64''' was released Dec. 23th, 2011. It is available on several mirrors which are listed [https://mirrors.fedoraproject.org/publiclist/Fedora/16/ppc64/ here].
 
It is known to work on the new Power7 machines and on PowerMac G5 with > 1Gb RAM. Installations on machines with less RAM might work, but that is untested yet (feedback welcome).
 
 
 
A fresh installation for F16 if you're currently using a pre-release is highly recommended so that you can verify that all reported and closed as fixed bugs have really been addressed in the final F16 release.
 
 
 
If the installation fails, here is a [http://sharkcz.livejournal.com/8649.html HOWTO] for an install that requires you to have a system with an older RHEL or Fedora installation and that doesn't use the usual anaconda installer.
 
 
On the mirrors are also install media and packages for [https://mirrors.fedoraproject.org/publiclist/Fedora/16/ppc PPC (32bit)]
Those are completely untested and any bugreports without patches attached that fix the issue will most likely be deferred atm as we're concentrating on 64bit as that's the only hardware that the developers currently have. We have to rely on the community to provide fixes for 32bit problems.
 
If you want to help out with testing, please report any problems on [https://fedoraproject.org/wiki/Architectures/PowerPC#PowerPC.2FPOWER_Special_Interest_Group IRC] or in [http://bugzilla.redhat.com bugzilla] (make sure to set the architecture to 'powerpc'). Feedback about installations on older hardware such as 32bit PowerMac G4 is appreciated, but as we're focusing on 64bit machines it might take some time to fix 32bit issues unless patches are attached to the bugreports.
 
 
== Previous Fedora for Power releases ==
 
The last Fedora release for PPC before F16 was Fedora 12 and can be found at http://download.fedoraproject.org/pub/fedora/linux/releases/12/Fedora/ppc/iso/
 
 
 


== Stable Release, GPG keys ==


== Fedora rebuild efforts ==
Fedora 25 is the latest stable release of Fedora for Power. It was announced on November 22, 2016. Please see [https://lists.fedoraproject.org/archives/list/announce@lists.fedoraproject.org/thread/FG5BBVWKJBRZUDGN7RXPFVLHLWELWF3P/ the release announcement] for additional details or download it directly from [https://alt.fedoraproject.org/alt/ here].
There are currently efforts ongoing to recompile all packages and prepare a F-17 release.  


This is the current [http://ppc.koji.fedoraproject.org/compare-f17.txt status of the package rebuild]:
Fedora for Power uses different GPG keys than the primary architectures. Check [https://fedoraproject.org/keys The official Fedora GPG key list] for a list of secondary arch keys.

The build of F18 packages has also been started and has made some [http://ppc.koji.fedoraproject.org/compare-f18.txt good progress]:
== Supported Architectures ==


[[File:Ppc-statistics-f18.png]]
Only 64bit machines (big endian Power5 or newer and little endian Power8 or newer) are supported, 32bit packages are not available anymore in F22 or newer. The last Fedora release with 32bit boot images was Fedora 17. Although it might be possible to install a 32bit F17 release and then update with the latest F21 packages, this is not supported by the Fedora PPC developers anymore.  


Fedora 18 and newer also includes several optimized packages for Power7 machines. These will be installed automatically if a Power7 processor is detected.

Stable Release, GPG keys

Fedora 25 is the latest stable release of Fedora for Power. It was announced on November 22, 2016. Please see the release announcement for additional details or download it directly from here.

Fedora for Power uses different GPG keys than the primary architectures. Check The official Fedora GPG key list for a list of secondary arch keys.

Release Notes

Supported Architectures

Only 64bit machines (big endian Power5 or newer and little endian Power8 or newer) are supported, 32bit packages are not available anymore in F22 or newer. The last Fedora release with 32bit boot images was Fedora 17. Although it might be possible to install a 32bit F17 release and then update with the latest F21 packages, this is not supported by the Fedora PPC developers anymore.

Fedora 18 and newer also includes several optimized packages for Power7 machines. These will be installed automatically if a Power7 processor is detected.

Previous Releases

You can find information about previous Fedora for Power releases at Architectures/PowerPC/PreviousReleases.

Build System & Resources

Koji

F25 or previous releases

Till F25, all official Fedora PowerPC packages are built by the koji build system at the PowerPC koji hub Everyone with a Fedora account can do scratch builds of packages on the PowerPC koji build system. After running fedora-packager-setup from the fedora-packager rpm

ppc-koji build --scratch f20 yourpkg.src.rpm

Scratch builds can be found here, and will be removed from koji automatically after a while.

For a build to end up in the final Fedora for Power distribution, that NVR must have been built on the primary Fedora koji and then pushed as an update for that release. koji-shadow is used by Fedora for Power to track both the stable (e.g. 'f20' during f20 branched development and 'f20-updates' after GA) and updates-testing tags of each release, as well as the current rawhide tag. Please feel free to find Dan Horák on the #fedora-ppc IRC channel if you have questions about the koji-shadow process.

Rawhide

On October 29, 2016 announcement was made to merge ppc64(le) koji builds of packages with primary koji.

To make a scratch build of package for ppc64 and ppc64le in Fedora rawhide, run:

  koji build --scratch --arch-override=ppc64,ppc64le rawhide yourpkg.src.rpm

PPC Shell access for debugging

Dan Horák (sharkcz) can provide you access to a PPC box for build debugging purposes. Just send him an e-mail with a request and a public SSH key. fedora-infra team is also working on providing easier access to a PowerPC VM for debugging build issues. Once we have it ready, we will update this section.
