== Latest PPC Fedora release ==
== Stable Release, GPG keys ==  


Latest Fedora release for PPC is currently Fedora 12 and can be found from http://download.fedoraproject.org/pub/fedora/linux/releases/12/Fedora/ppc/iso/
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].


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.


We're doing composes of the F-16 packages and create bootable DVD isos.
=== Release Notes ===
Repositories with the latest packages can be found on [http://ppc.koji.fedoraproject.org/mash/16/ our koji hub], the DVD images are currently available in a [http://ppc.koji.fedoraproject.org/scratch/karsten/iso/ temporary location]. Don't expect to be able to install with these DVD isos yet or with the bootimages from the mash directories, it might or it might not work on your machine due to the new combined initrd which is to large for some PowerPC firmwares. The images are known to work on the new Power7 machines and on a PowerMac G5 with 8Gb RAM. There's a [http://sharkcz.livejournal.com/8649.html workaround] for that, but it requires to have a system with an older RHEL or Fedora installation.


'''UPDATE''' The ISOs from 20110809 and newer have been built with a branch called treebuilder of our [https://fedorahosted.org/lorax/ lorax] tool. We're now back to a small initrd and a second stage ramdisk. [https://fedoraproject.org/wiki/User:Wwoods/Building_images_with_treebuilder Will Woods treebuilder] page contains more information about his enhancements, but make sure to read the [https://fedoraproject.org/wiki/User_talk:Wwoods/Building_images_with_treebuilder discussion] of known issues and workarounds, too.

If you want to help out with testing, please report any problems on [https://fedoraproject.org/wiki/Architectures/PowerPC#PowerPC.2FPOWER.2FCell_Special_Interest_Group IRC] or in [http://bugzilla.redhat.com bugzilla] (make sure to set the architecture to 'powerpc'). Especially feedback about installations on older hardware such as 32bit PowerMac G4 is appreciated.
== Supported Architectures ==


== Fedora rebuild efforts ==
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.  
There are currently efforts ongoing to recompile all packages and prepare a F-15 release or if we find out that we are too far behind the primary archs to have a F-16 release. This is the current status of the package rebuild:
[[File:Ppc-statistics.png]]


=== Rebuild problems, TODO list ===
Fedora 18 through Fedora 23 also includes several optimized packages for Power7 machines. These will be installed automatically if a Power7 processor is detected.  The focus for Fedora 24 and newer is on Power8 or newer hardware and the optimizations for these CPU types are handled through a different mechanism.
- The most urgent problem at the moment is to get the latest version installable (maybe even with some workarounds for problems) so that the installer and bootloader teams can pick up the work. <br>


- The Haskell Compiler (ghc) is available on PPC64. Jens Petersen & Jiri Skala work on bumping haskell-platform packages for PPC64. Unfortunately upstream don't support GHCi & NGC for PPC64. Therefore following packages aren't available for PPC64:
Fedora 25 able to be installed also on Mac G5 machine as per https://github.com/masterzorag/G5_ppc64-linux
* ghc-template-haskel
* ghc-ForSyDe
* ghc-QuickCheck
* ghc-hamlet
* ghc-parameterized-data
* ghc-type-level
* haskell-platform packages.


- yaboot only available on PPC which means we currently need some hacks for 64bit boot images

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 through Fedora 23 also includes several optimized packages for Power7 machines. These will be installed automatically if a Power7 processor is detected. The focus for Fedora 24 and newer is on Power8 or newer hardware and the optimizations for these CPU types are handled through a different mechanism.

Fedora 25 able to be installed also on Mac G5 machine as per https://github.com/masterzorag/G5_ppc64-linux

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.
