Fedora for mipsel and Creator CI20 image
by Michal Toman 28 Jul '15

28 Jul '15

Greetings, I do finally have a working Fedora image for the Creator CI20 [1]. It boots into headless - you can either use serial console or SSH to connect - and has a working DNF to install packages. Mock should also be fully functional. I have started stage4 rebuilding a few days ago and will keep the repos [2] up to date. Issues are listed on the wiki [3], any help on any of them would be appreciated (top priority now being kernel packaging and java bootstrap). There is also a short blog post by IMG [4] promoting Fedora on Creator CI20. Give it a try, any feedback is welcome.

Reviving Fedora MIPS
by Michal Toman 28 Jul '15

28 Jul '15

Greetings everyone, you might know me from my former work on ABRT, or later Power and s390. For the last few months however, I have been collaborating with Imagination Technologies to bring back Fedora for MIPS. A brief history - some effort to bootstrap Fedora for MIPS has been done around Fedora 11/12/13, but died afterwards because of lack of interest. Even though the RPMs were labelled with mips64el architecture, they were using the hybrid n32 ABI with 32-bit pointers and 64-bit data, rather than the full 64-bit n64 ABI. Since we decided to go with n64 rather than n32, we have tried to bootstrap the distribution from scratch (well, almost) to see how much problems we will run into. I need to say that I was very surprised that a majority of packages build fine with no or just minor tweaks to specfiles and very few packages do require actual code patching. Anyway, we have now arrived into a state where Fedora mips64el userspace can be booted and played with. I have created a QEMU image [1] and all the packages and repositories are available from mipsfedora.imgtec.com [2]. I have also created some wiki pages [3] briefly describing what we are doing and will continue to expand them in the following days to be more detailed. Apart from mips64el, we have lately started working on 32-bit mipsel, to be ran on the Creator CI20 Borad [4]. This is basically 3 months behind mips64el so there are no significant results yet, but hopefully will be soon. Future plans are, naturally, to turn MIPS into a fully-fledged secondary architecture, deploy koji-shadow, compose releases and do everything other secondary archs do. Build hardware is likely to be donated by Imagination Technologies. Any help would be appreciated, especially in the area of kernel, u-boot and some specific languages - haskell, erlang, ocaml etc. I have already been playing with some of those and there is a list of issues on the wiki. Hopefully you will like Fedora MIPS back Regards, Michal [1] http://mipsfedora.imgtec.com/development/22/mips64el/images/20150601/ [2] http://mipsfedora.imgtec.com/development/22/mips64el/ [3] https://fedoraproject.org/wiki/Architectures/MIPS/2015Bootstrap [4] http://community.imgtec.com/platforms/creator-ci20/
