oSSN19 - openSUSE on ARM
- 1. Guillaume GARDET ARM engineer guillaume@opensuse.org openSUSE on ARM What happened since about a year
- 2. Summary ● What is openSUSE on ARM? ● Overview of openSUSE on ARM workflow ● Open Build service – OBS ● OpenQA ● Tumbleweed, Kubic and Leap ● openSUSE wiki ● The TODO list
- 3. What is openSUSE on ARM?
- 4. What is openSUSE on ARM? ● Simply openSUSE running on ARM architectures ● openSUSE runs on : – 32-bit: armv6 (TW only), armv7 – 64-bit: aarch64 (armv8.x) ● ARM SoC covers a wide range of applications: – from small low power embedded systems (Raspberry Pi) – to powerfull servers and HPC (ThunderX2) ● UEFI vs custom bootloader system
- 5. Overview of openSUSE on ARM workflow
- 6. Overview of openSUSE (on ARM) workflow
- 7. Overview of openSUSE on ARM workflow ● openSUSE:Factory:ARM project is a project link to openSUSE:Factory project ● openSUSE:Leap:15.1:ARM project is a project link to openSUSE:Leap:15.1 project – all sources are reused and updated in real-time – a small overlay is available to handle the snapshot version and the content of ISO and FTP trees

- 10. Open Build Service - OBS
- 11. OBS ● More aarch64 build power in OBS (thanks to Marvell/Cavium) – obs-arm-7: ThunderX2 machine: In November 2018 https://news.opensuse.org/2018/11/06/marvell-tuxedo-computers-spo nsor-opensuse-project/ – obs-arm-8/-9: 2 more ThunderX2 machines: In February 2019 ● Which allowed to: – remove snapshoting and follow x86 for both Tumbleweed and Leap 15.1 – enable ARM builds on more devel projects to catch build failures earlier and have package maintainers to fix it before submitting to Factory
- 12. OBS ● ARM containers now published when ARM is released, not when x86 is. ● Configuration of ARM OBS workers have been updated to better fit requirements of packages – less workers with more CPU, RAM and disk
- 13. openQA
- 14. openQA ● How openQA works? – 1 server (shared for all architectures), with a web interface + API: ● hold files (ISO, HDD images, repositories, etc.) ● hold test suites informations (tests scenarios, needles, etc.) ● control test runs ● store test results – X machines: ● Running multiple VM (qemu) to run tests inside ● Each test runs some actions and checks if the results are expected
- 16. openQA ● Mediacheck test: – Boot on ISO and start the Check installation media – Make sure no errors are found
- 17. openQA ● Only for AArch64, no openQA tests for armv6/armv7 targets ● In 2018: Seattle machine - with 6x Cortex-A57 and 32GB RAM: only 2 workers ● Added more tests for TW and Leap 15, but limited by the number of aarch64 workers Image from: https://en.opensuse.org/HCL:Seattle
- 18. openQA ● Fall 2018: a new machine (D05) - with 64x Cortex-A72, 128GB RAM, 480GB SATA SSD: 10 workers ● Added even more tests for TW and Leap 15.1 to get a good coverage, including: upgrades, btrfs tools, virtualization, RAID, multipath, GNU/health, etc. ● Tests and needles sometimes needed to be update to handle aarch64 properly Image from: http://open-estuary.org/d05/
- 19. openQA ● Non arch dependant improvements: – New tests added – A developer mode – Script to use unmerged github PR updates on openqa.o.o: openqa-clone-custom-git-refspec – Support for huge pages with qemu backend – Support to pass generic options to qemu
- 20. openQA ● On 04/04/2019: – On Tumbleweed: 68 tests ● Kubic: 5 tests ● DVD: 47 tests ● NET: 14 tests ● JeOS: 2 tests – On Leap: 59 tests ● DVD: 45 tests ● NET: 12 tests ● JeOS: 2 tests
- 21. openQA ● On 04/04/2019: – On Tumbleweed: 68 tests ● Kubic: 5 tests ● DVD: 47 tests ● NET: 14 tests ● JeOS: 2 tests – On Leap: 59 tests ● DVD: 45 tests ● NET: 12 tests ● JeOS: 2 tests Kubic is only on Tumbleweed LXDE pattern is only available on Tumbleweed DVD + openqa_bootstrap test Tumbleweed create an HDD image of released Tumbleweed and test upgrade to current openQA snapshot
- 24. Tumbleweed ● openSUSE Tumbleweed for AArch64 is now officialy supported and is no more a "best effort port" ● Lots of packages fixed: build time (OBS) and runtime (openQA): Kernel, Firefox, Chromium, Java, etc. ● New packages/builds: LDC compiler, FPC compiler, libgpiod, etc. ● Some feature additions to existing package (including Mesa/libdrm) for a better support
- 25. Tumbleweed ● Switch more armv7 boards to EFI/Grub2 (SabreLite, Chromebook snow) ● Get some boards out from Contrib: in favor to Factory:ARM (udooneo, etc.) ● Lots of kernel support improvements (mainly aarch64) thanks to always up-to-date kernel
- 26. Kubic - https://kubic.opensuse.org/ ● What is Kubic? – A certified Kubernetes distribution and container-related technologies built by the openSUSE community – A tumbleweed flavor ● Built in OBS and tested in openQA along Tumbleweed ● Kubic is officially supported on ARM (aarch64) since January 2019: https://kubic.opensuse.org/blog/2019-01-30-kubiconaarch64/
- 27. Leap 15.1 ● How is Leap built? – Inherit SLE15-SP1 packages for core packages: gcc, kernel, qemu, etc. – Inherit Leap 15.0 packages for other packages – If package maintainers want to, they can push updates from Tumbleweed: Krita, Firefox, etc. ● Packages fixed (builds and runtime)
- 28. Leap 15.1 ● Switch more armv7 boards to EFI/Grub2 (SabreLite, Chromebook snow) ● Ready to use images (JeOS, docker): – Tested in openQA – Always up-to-date images released
- 29. openSUSE wiki
- 30. Wiki - https://en.opensuse.org/Portal:ARM ● ARM pages have been updated on the openSUSE wiki: – Portal:ARM updated – HCL pages updated – New HCL pages: D05, Overdrive 1000, etc. – Page with latest tests of systems updated: https://en.opensuse.org/openSUSE:Supported_ARM_boards
- 31. The TODO list
- 32. The TODO list ● Improve continuously the wiki with: – new information – up-to-date information ● Improve OBS: – enable ARM build on more devel projects – Speed-up (armv7) images build: current bootleneck which slowdown Tumbleweed
- 33. The TODO list ● Improve openQA: – Add more aarch64 tests? – Add armv7 images tests? – Add tests on real hardware (RPi3)? – Increase the number of openQA workers to speed-up tests? ● Monitor continuously build failures and test failures and fix them ASAP
- 34. The TODO list ● Report and/or fix bugs on openSUSE bugzilla ● Need some help to: – Test and get feedback on systems (boards / servers) people use: even if all is fine – Improve graphic stack, including PCI-e gfx card (nvidia, amd, etc.) and also integrated into the SoC (nvidia, adreno, Mali, etc.)
- 35. The TODO list ● Please join us: – IRC: #opensuse-arm on Freenode – ML: opensuse-arm@opensuse.org
