Fedora 17
Fedora 17 for Power was announced on June 14th, 2012. Please see the release notes for additional details.
Fedora 16
Fedora 16 for PPC64 was released Dec. 23th, 2011. It is available on several mirrors which are listed 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 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 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 IRC or in 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 status of the package rebuild:
The build of F18 packages has also been started and has made some good progress:
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.
- 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 bugzilla #704236
The PowerPC koji build system
All official Fedora PowerPC packages will be built by the koji build system at the PowerPC koji hub
All non-scratch packages that haven't been deleted by the garbage-collector are available at the package storage, scratch builds can be found for a few days at the scratch repository
Building packages on the PowerPC koji build system
Everyone with a Fedora account can do at least scratch builds of packages on the PowerPC koji build system, 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: bugzilla 787776 )
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.
