Hi Michal,
Your commit regarding update on _constraints for kernel for 5.3 https://kernel.opensuse.org/cgit/kernel-source/commit/?h=stable&id=52 7cb6696c488826b46b28aa803524a60ece89de is wrong on ARM and leads to wait too long for kernel builds as it can be schedule on 2 workers only on OBS! Moreover, those 2 workers are on a single machine which is slow.
According to kernel:Master values reported by OBS for ARM, 28G of disk space is enough for aarch64 and 15G is enough for armv6/armv7.
28 GB for aarch64 is not very different from x86_64 so unless 35 GB constraint results in observable problems (which doesn't seem to be the case so far), I would prefer keeping it.
As stated in my initial e-mail, it _is_ a big problem with only 2 slow workers being able to build kernels for ARM. Up to 32768 MB it is ok, as a good number of build workers are usable.
As for 32-bit ARM architectures, with builds needing 15 GB at the moment, I would suggest using something like 20 GB to give us some reserve (the buildroot size keeps growing slowly but steadily).
20 G is fine. I can send a patch for the update. Cheers, Guillaume
Michal
