== Current PPC Fedora release ==
 
'''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].  


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).
== Current Development ==


[[Architectures/PowerPC/CurrentDevelopment]] tracks our current development efforts.


Also see the [http://ppc.koji.fedoraproject.org/koji/serverstatus dashboard] for constantly updated stats on when the most recent pushes were, number of unsigned packages, most important build failures, etc.


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.
== Stable Release, GPG keys ==


Fedora 23 is the latest stable release of Fedora for Power. It was announced on November 3, 2015. Please see [https://lists.fedoraproject.org/pipermail/announce/2015-November/003294.html the release announcement] for additional details or download it from your closest [https://admin.fedoraproject.org/mirrormanager/mirrors/Fedora/23/ppc64 mirror].


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.


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.
=== Release Notes ===
* [[Architectures/PowerPC/24|Fedora 24]]


== Supported Architectures ==


On the mirrors are also install media and packages for [https://mirrors.fedoraproject.org/publiclist/Fedora/16/ppc PPC (32bit)]
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.  
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.
Fedora 18 and newer also includes several optimized packages for Power7 machines. These will be installed automatically if a Power7 processor is detected.


== preparing for the Fedora 17 PPC release ==
== Previous Releases ==
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/F17AlphaPPC_checklist F17AlphaPPC_checklist] / [https://fedoraproject.org/wiki/F17BetaPPC_checklist F17BetaPPC_checklist]


This is the [https://fedoraproject.org/wiki/F17_PPC_schedule schedule] for the F17 PPC release.

== Fedora rebuild efforts ==
== Build System & Resources ==
There are currently efforts ongoing to recompile all packages and prepare a F-17 release.


This is the current status of the package rebuild:
===Koji===  
 
All official Fedora PowerPC packages are built by the koji build system at the
[[File:Ppc-statistics.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.
 
- segmentation fault of alt-ergo.opt during build [https://bugzilla.redhat.com/show_bug.cgi?id=704236 bugzilla #704236]

== Building packages on the PowerPC koji build system ==
 
Everyone with a [http://fedoraproject.org/wiki/Join_the_package_collection_maintainers#Get_a_Fedora_Account Fedora account] can do at least scratch builds of packages on the PowerPC koji build system, [http://fedoraproject.org/wiki/Join_the_package_collection_maintainers package maintainers] who can check changes into the git repositories can build updated packages that will later on end up in the distribution.
 
=== Doing scratch builds ===
 
After running fedora-packager-setup from the fedora-packager rpm
  ppc-koji build --scratch f17 yourpkg.src.rpm
These builds will be removed from koji automatically after a while.
 
=== 'real' builds ===
 
'Real' builds will be pulled into the package repositories and into the install images, unless they got replaced by later versions.
After running fedora-packager-setup from the fedora-packager rpm
ppc-koji build f17 "$(fedpkg giturl)"
or
fedpkg build --target=f17
(this works only when you have a symlink from ~/.koji/ppc-config to ~/.koji/config)
(currently broken: [https://bugzilla.redhat.com/show_bug.cgi?id=785776 bugzilla 787776] )


== PPC Shell access for debugging ==
Scratch builds can be found [http://ppc.koji.fedoraproject.org/scratch/ here], and will be removed from koji automatically after a while.

== Documentation ==
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 [[user:dwa|dwa]] or [[user:karsten|Kick_]] on the #fedora-ppc IRC channel if you have questions about the koji-shadow process.

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, most important build failures, etc.

Stable Release, GPG keys

Fedora 23 is the latest stable release of Fedora for Power. It was announced on November 3, 2015. Please see the release announcement for additional details or download it from your closest mirror.

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

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 dwa or Kick_ on the #fedora-ppc IRC channel if you have questions about the koji-shadow process.

PPC Shell access for debugging

Brent Baude (rangerpb) 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.
