Fedora 18 for Power is currently in development. The schedule is following the one for primary as closely as possible [https://fedoraproject.org/wiki/Releases/18/Schedule Fedora 18 schedule]. As usual we have architecture specific blocker tracking bugs open for Alpha, Beta and RC:

Fedora 18 is the latest stable release of Fedora for Power. It was announced on January 22nd, 2013. Please see [https://fedoraproject.org/wiki/Architectures/PowerPC/F18_release_announcement the release announcement] for additional details or download it from your closest [https://mirrors.fedoraproject.org/publiclist/Fedora/18/ppc64/ mirror].

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/
+
 
+
 
+
 
+
 
+
 
+
== Fedora rebuild efforts ==
+
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-f18.txt status of the package rebuild]:
+
 
+
[[File:Ppc-statistics-f18.png]]
+
 
+
 
+
=== Rebuild problems, TODO list ===
+
- 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:
+
* 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. This won't change as the PPC firmware seems to be 32bit only.
+

Scratch builds can be found [http://ppc.koji.fedoraproject.org/scratch/ here], and will be removed from koji automatically after a while.
  
'Real' builds will be pulled into the package repositories and into the install images, unless they got replaced by later versions.

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. 'f18' during f18 branched development and 'f18-updates' after GA) and updates-testing tags of each release, as well as the current rawhide tag.

PowerPC/POWER Special Interest Group

Members

Meetings

  • We don't schedule any IRC meetings, although starting at the Alpha phase of any release we'll try to find some time each day to discuss open issues on our #fedora-ppc[?] channel on IRC .
  • The last 'real' meeting of the Fedora-PPC team took place at the FUDcon 2013 in Lawrence, Kansas.

Current Development

Architectures/PowerPC/CurrentDevelopment tracks our current development efforts. Fedora 19 has not yet branched from Rawhide.

Stable Release

Fedora 18 is the latest stable release of Fedora for Power. It was announced on January 22nd, 2013. Please see the release announcement for additional details or download it from your closest mirror.

Previous Releases

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

Build System & Resources

Koji

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 f17 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. 'f18' during f18 branched development and 'f18-updates' after GA) and updates-testing tags of each release, as well as the current rawhide tag. Please feel free to find dwa or Kick_ on the #fedora-ppc IRC channel if you have questions about the koji-shadow process.

PPC Shell access for debugging

David Woodhouse (dwmw2), Josh Boyer (jwb) or Karsten Hopp (Kick_) may provide you access to a PPC box for build debugging purposes. Just send them an e-mail with an request and a public SSH key.
