get to the point where F-14 is bootable and installable with pungi images

Accomplished

set up externally/publically available koji instance
s390x koji instance

History

FUDcon 2008 was an excellent event. During the conference, a session on secondary arches was presented and there was an excellent effort made to reach out to new arches.

After several months of bootstrapping as of June 2009 we've reached a state where we have most packages built from current Fedora rawhide CVS. There are still around ~500 failures, most of which are related to java and ocaml dependencies (ocaml is not available on s390x).

News of September 2010: We're now getting really close to Rawhide and we have a working install tree available thats basically based on current Fedora 14. Previously we only provided a hercules images as well as a tarball from a root FS as installs weren't possible. We still provide those, but now you can do your own installs again, too!

For those interested in trying it out you access everything needed from here:

http://secondary.fedoraproject.org/pub/alt/spins/S390/

You will find several files there:

README
- Very brief howto get everything up and running, either for running preinstalled hercules images or how to do a complete install yourself
fedora-14-s390x.img.bz2
- Hercules Fedora 14 s390x DASD image bzip2 compressed. WARNING! This file is 8GB uncompressed (only 350MB compressed), so make sure you have the room for it.
f11-s390x.img
- Hercules Fedora 11 s390x DASD image
f11-s390x.tar.bz2
- tarball of the whole tree. Can be unpacked on a real machine (confirmed it works!)
anaconda-ks.cfg
- Sample kickstart file that installs a very basic system on a dasd image. WARNING! Wipes out the whole partition table, so use with care
hercules.cnf
- hercules emulator config file
hercules.init
- Small script to start up hercules with some iptables rules for NAT (might require you to modify your personal rules in order to work properly)
generic.prm
- Kernel command line parameter file, needed for installation

Supported hardware

IBM system Z models z9 or newer
Hercules emulator version 3.07 or SVN revision >= 6605

Tips

Notes for application developers and package maintainers

some hardware that's usual on other platforms is missing, like
- USB
- FireWire
- InfiniBand

memory ordering is big-endian

Please make sure to build into the correct target, don't mix dist-f14 and dist-f14-updates

To test a build for your specific package for s390x do this:

After running fedora-packager-setup from the fedora-packager rpm

s390-koji build --scratch dist-f14 yourpkg.src.rpm

To build a package which should end up in the F-14 tree, the package needs to be commited in dist-git and then be built with:

s390-koji build dist-f14 "$(fedpkg giturl)"
