Thanks for taking care of this problem.
I'm down to 32MB now, which seems okayish for a few hours of hacking. Next problem I noticed that we have enabled "CMA" in our kernel config for arm (it is disabled on other architectures), which seems to take away quite some memory for unpacking the kiwi initrd. with artificially lowering the memory to Raspberry Pi 1 levels I can run out of memory while unpacking initrd, which is bad. Any objection to disabling that ? I couldn't quite figure out why we want it to be enabled, as usual the git commit messages that enabled it are sparse :( Greetings, Dirk -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

It used to be necessary for Exynos based Chromebooks and Snapdragon based boards among others. The latter should no longer be the case with IOMMU, but I recall on the Chromebooks we can't enable Exynos IOMMU so we still need CMA there.
