'''Fedora 16 for PPC64''' has been released Dec. 23th, 2011. It is available on several mirrors which are listed [https://mirrors.fedoraproject.org/publiclist/Fedora/16/ppc64/ here].
+
== Stable Release ==
  
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).  
+
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].
  
 +
== Supported Architectures ==
  
 +
Only 64bit machines (Power5 or newer) are supported, but we still provide 32bit packages. 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 packages, this is not supported by the Fedora PPC developers anymore. Interested developers might also be able to create their own 32bit boot images for the latest Fedora release with pungi but this is also not supported by the Fedora PPC developers.
  
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.  
+
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]].
  
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.

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.2FCell_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.

+
== preparing for the Fedora 16 PPC release ==
+
We're using the Alpha/Beta/Final Fedora release process for secondary arches from [https://fedoraproject.org/wiki/User:Jlaska/Draft_Fedora_16_Alpha_PowerPC_Release_Criteria James Laska]: [https://fedoraproject.org/wiki/F16AlphaPPC_checklist F16AlphaPPC_checklist] / [https://fedoraproject.org/wiki/F16BetaPPC_checklist F16BetaPPC_checklist]
+
 
+
This is the [https://fedoraproject.org/wiki/F16_PPC_schedule schedule] for the F16 PPC release.
+
 
+
== Fedora rebuild efforts ==
+
There are currently efforts ongoing to recompile all packages and prepare a F-16 release.
+
 
+
This is the current status of the package rebuild:

+
=== 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

Getting Started with Fedora for Power::
Check out our current development efforts and join the Fedora for Power team on IRC in #fedora-ppc[?] on http://freenode.net

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.

Also see the dashboard for constantly updated stats on when the most recent pushes were, number of unsigned packages, etc.

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.

Supported Architectures

Only 64bit machines (Power5 or newer) are supported, but we still provide 32bit packages. 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 packages, this is not supported by the Fedora PPC developers anymore. Interested developers might also be able to create their own 32bit boot images for the latest Fedora release with pungi but this is also not supported by the Fedora PPC developers.

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

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.
