While in the past MIPS boards were either low-end PIC32 or found in routers running OpenWRT at most, Imagination themselves have recently released the Creator CI20 board (Ingenic, MIPS32) running Debian. And the Shield Pro (previously iGuardian) kickstarter project (Octeon-III, MIPS64) promises to become a playground for testing KVM hardware virtualization.
Porting openSUSE to MIPS will involve setting up an OBS instance linked to Factory (update: done) and cross-compiling a set of packages for an initial bootstrap (update: in progress). Maybe this can be scripted to some degree, as there will be some overlap with the ARM ILP32 port project.
For lack of hardware, qemu-linux-user would need to be used for building in OBS, as done initially for the AArch64 port.
Looking for hackers with the skills:

Does this mean that ultimately I could run openSUSE on this thing?

For now I'm working on cross-compiling userspace binaries and bootstrapping core packages like rpm. mipsel with current default options should run on a wide range of devices; mips64 I'm building in parallel, which will be less widely supported. Bootloader and kernel support for individual devices I have not yet looked into at all - we may need to employ a similar scheme as for ARM, with devel:MIPS:Factory:Contrib:Foo projects for vendor kernels or U-Boot forks.

Linux on Cavium CN23XX cards by tsbogend
Before Cavium switched to ARM64 CPUs they developed quite powerful MIPS based SOCs. The current upstream Linux kernel already supports some Octeon SOCs, but not the latest versions. Goal of this Hack Week project is to use the latest Cavium SDK to update the Linux kernel code to let it running on CN23XX network cards.
Bootstrap openSUSE on LoongArch by glaubitz
Description
LoongArch is a new architecture from China which has its roots in the MIPS architecture. It has been created by Loongson and is already supported by Debian Ports, Gentoo and Loongnix.
Upstream support for LoongArch is already quite complete which includes LLVM, Rust, Golang, GRUB, QEMU, LibreOffice and many more. In Debian Ports, where the port is called "loong64", more than 95% of the whole Debian archive have been successfully built for LoongArch.
QEMU support is rather complete and stable such that packages can be built in emulated environments. Hardware can also be requested by Loongson on request for free. Access to real hardware is also provided through the GCC Compile Farm.
Goals
The initial goal should be to add LoongArch to OBS and build a minimal set of packages.
Resources
- Introduction to LoongArch: https://docs.kernel.org/arch/loongarch/introduction.html
- LoongArch community on Github: https://github.com/loongarchlinux
- Debian Ports repository for loong64: http://ftp.ports.debian.org/debian-ports/pool-loong64/main/
- Gentoo stage3 for loong: https://www.gentoo.org/downloads/#loong
Results
- An initial set of packages for openSUSE loongarch64 has been successfully bootstrapped
- An OBS project has been set up to build packages for openSUSE loongarch64 with more than 3000 packages being built already
- A work-in-progress guide on how to bootstrap a new openSUSE port from Debian has been created
- A work-in-progress guide on how to add a new target to the openSUSE toolchain has been created
Acknowledgements
- Thanks to Adrian Schröter and Rüdiger Oertl for the help with setting up the FTP space and OBS project
- Thanks to Dirk Müller for the input on how to get started with a new port
- Thanks to Richard Biener for quickly accepting my submit requests to add loongarch64 support to the toolchain
Switch software-o-o to parse repomd data by hennevogel
Currently software.opensuse.org search is using the OBS binary search for everything, even for packages inside the openSUSE distributions. Let's switch this to use repomd data from download.opensuse.org
Learn obs/ibs sync tool by xlai
Description
Once images/repo are built from IBS/OBS, there is a tool to sync the image from IBS/OBS to openqa asset directory and trigger openqa jobs accordingly.
Goals
Check how the tool is implemented, and be capable to add/modify our needed images/repo in future by ourselves.

Git CI to automate the creation of product definition by gyribeiro
Description
Automate the creation of product definition
Goals
Create a Git CI that will:
- automatically be triggered once a change (commit) in package list is done.
- run tool responsible to update product definition based on the changes in package list
- test the updated product definition in OBS
- submit a pull request updating the product definition in the repository
NOTE: this Git CI may also be triggered manually

Research openqa-trigger-from-obs and openqa-trigger-from-ibs-plugin by qwang
Description
openqa-trigger-from-obs project is a framework that OSD is using it to automatically sync the defined images and repositories from OBS/IBS to its assets for testing. This framework very likely will be used for the synchronize to each location's openqa include openqa.qa2.suse.asia Beijing local procy scc scc-proxy.suse.asia(although it's not a MUST to our testing) it's now rewriting requests to openqa.qa2.suse.asia instead of openqa.suse.de, the assets/repo should be consistent the format Beijing local openQA is maintaining an own script but still need many manually activities when new build comes, and not consistent to OSD, that will request many test code change due to CC network change
Goals
Research this framework in case it will be re-used for Beijing local openQA, and will need to be setup and maintained by ourselves
