It might not be perfect, but AFAIK at least one Linux distribution (Sailfish OS) has been using emulated 32-bit ARM on x86_64 hosts since 2013 to build everything without any native build hardware.

Or even using armv7hl "chroot" on aarch64 host ? As we are not supposed to be emulated once the hw support it and the kernel is built with COMPAT (which in the case in Fedora). ___ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org

Which arch should we add to Copr?
Hello, we are now able to build for armhfp and s390x architectures in Copr. However, due to storage issues, we can enable only one of these two right now. Which architecture would you prefer to have?
