There are two scripts involved. The staging plugin and the totest manager. It used to be a link but we had tons of merge conflicts all the time, which is why we removed the link at some point. Looking at PowerPC I guess some of those conflicts could be avoided by splitting more things out of openSUSE.product and include architecture specific files instead. it would be nicer to maintain the ARM related things in openSUSE:Factory but SR's don't get accepted and bribing by email to get one liner fixes committed in less than a week of roundtrip is also not always the best thing to spend time on. One of the reasons why it took so long to get a testable aarch64 into openQA... The separate project is fine as long as it only contains the products most of the time.

We're building with native hardware since ~ 12 hours on Factory after some hickups (and still sorting out the fallout of that). So that problem should be solved hopefully. The tree is about to be ready to be published (if only the OBS scheduler would actually notice it). Maybe its the "watching a pot with water never boilds" phenomenon but whenever I check it, there are 10-20 min pauses where the OBS scheduler just does nothing at all, including not noticing that it could publish the tree. > Meanwhile maybe an installation DVD could help.

Host kernel is 4.0.0-rc5, guest kernel is 3.19.3 usually (for Factory). Any other ideas? it seems to me that something is causing the cpu's 4-8 on the host to stall quite frequently, but I haven't been able to identify it yet.

[opensuse-arm] aarch64 in openQA
Hi, As you may have noticed openqa.opensuse.org has some aarch64 jobs. It was quite some effort to get there but it's far from done yet. 1. Build Power At the moment there's one openQA worker running on a PPC64 host (power8). That host is fast enough to run the emulation reasonably well. To do serious tests we need real hardware with kvm though. Not just for openQA but also for OBS. The image in openQA is just the NET iso that installs from a static ftp repo from two weeks ago. The ftp tree wasn't published since then as it never finished building. Factory is moving too fast, aarch64 can't catch up. Meanwhile maybe an installation DVD could help. The limited set of packages on the DVD probably has a chance to finish in time. 2. Project Setup To get a real Tumbleweed for aarch64 the OBS setup needs to be changed: - openSUSE:Factory:ARM/_product need to become a link to openSUSE:Factory/_product. That way arm inherits the Tumbleweed version number. - openSUSE:Factory:ARM:ToTest needs to be created to hold the snapshots that go into openQA 3. Scripts The magic factory scripts (totest manager, pattern generator) need to be adjusted. Dinar did most of the heavy lifting for ppc so the scripts are now able to handle another architecture. The spots needed for aarch64 should be easy to find by searching for ppc. cu Ludwig -- (o_ Ludwig Nussel //\ V_/_ http://www.suse.de/ SUSE Linux GmbH, GF: Felix Imendörffer, Jane Smithard, Jennifer Guild, Dilip Upmanyu, Graham Norton, HRB 21284 (AG Nürnberg) Maxfeldstraße 5; 90409 Nürnberg; Germany -- To unsubscribe, e-mail: opensuse-arm+unsubscr...@opensuse.org To contact the owner, e-mail: opensuse-arm+ow...@opensuse.org

I studied on the BOOT disk the file boot.script and found in the value for bootargs the parameter disk=/dev/disk/by-id/mmc-0_0x1537043d . I have the feeling there should be -part? appended, where ? should be 2 or 3. Both root= and resume= have -part3. respectively -part4 appended. -- fr.gr. member openSUSE Freek de Kruijf -- To unsubscribe, e-mail: opensuse-arm+unsubscr...@opensuse.org To contact the owner, e-mail: opensuse-arm+ow...@opensuse.org
