== 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/
 
 
We're doing composes of the F-16 packages and create bootable DVD isos.
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.


'''UPDATE''' Latest ISO from 20110920 is installable from previously installed system using network installation source. Some workarounds are needed to finish it:
Fedora 40 is the latest stable release of Fedora for Power. It was announced on April, 2024. Please see [https://fedoramagazine.org/announcing-fedora-40/// the release announcement] for additional details or '''Download directly from [https://alt.fedoraproject.org/alt/ here].'''
# Create one spare partition to hold the LiveOS folder from the ISO, create ext4 filesystem on it, mount it,
# copy LiveOS folder from the ISO to this partition,
# put the vmlinuz and initrd.img from  ppc/ppc64 folder on ISO to /boot,
# edit /boot/etc/yaboot.conf, add following lines, replace DEVICE with the partition holding the LiveOS folder:
image=/vmlinuz
label=Fedora
initrd=/initrd.img
read-only
append="root=live:/dev/DEVICE vnc serial"
# Reboot the system and watch the console,
# after unsuccessful network configuration hit <code>^Z</code>,
# run <code>dhclient</code>,
# get the PID of NetworkManager using <code>ps aux</code>, terminate it,
# hit <code>^D</code> to continue with the installation,
# connect to vnc, proceed to partitioning,
# choose custom layout, do not remove the partition with LiveOS folder,
# input the path to installation repository,
# finish the installation.
After these steps it should boot to newly installed system. I didn't use LVM for the installation and installed only minimal package set.


'''UPDATE''' Latest ISO from 20110929 is installable from DVD, although you might have to add the parameter 'serial' as a kernel parameter at the yaboot prompt. Don't choose to install  'Graphical Desktop' with this iso as there's a missing dependency that'll cause your installation to abort.
Fedora for Power uses now primary architectures GPG keys. Check [https://fedoraproject.org/keys The official Fedora GPG key list] for a list of primary/secondary keys per releases.
There are also 20110930 images for PPC (32bit). Those are completely untested and any bugreports need to be ignored atm as we're concentrating on getting 64bit done (unless there's a patch attached that fixes the issue, see below).


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 ==
== Supported Architectures ==
We're using the Alpha 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]


Only 64bit machines (little endian Power8 or newer) are supported now; 


== Fedora rebuild efforts ==
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-16 release.  


This is the current status of the package rebuild:
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.

=== Rebuild problems, TODO list ===
Fedora 28 is last release for ppc64 (BE)
- 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>
Due the limited resource and clear preference of the ppc64le architecture in any new developments, it was decided that ppc64 architecture will transfer into a maintenance mode where the new features (eg. Atomic Host compose) we plan for ppc64le won't be added, see  [https://lists.fedoraproject.org/archives/list/ppc@lists.fedoraproject.org/message/C23EQYITA4DQWM7CQF6LJC5ABXY2XIEM/ email] for details.


- 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

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

Stable Release, GPG keys

Fedora 40 is the latest stable release of Fedora for Power. It was announced on April, 2024. Please see the release announcement for additional details or Download directly from here.

Fedora for Power uses now primary architectures GPG keys. Check The official Fedora GPG key list for a list of primary/secondary keys per releases.

Release Notes

Supported Architectures

Only 64bit machines (little endian Power8 or newer) are supported now;

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

Fedora 28 is last release for ppc64 (BE) Due the limited resource and clear preference of the ppc64le architecture in any new developments, it was decided that ppc64 architecture will transfer into a maintenance mode where the new features (eg. Atomic Host compose) we plan for ppc64le won't be added, see email for details.

Previous Releases

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

Build System & Resources

Koji

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.
