What are the limitations there? Is it worth it?
Few years ago we transformed the gnutls' upstream CI from baremetal h/w to qemu-user [0] (reasoning was pretty much what you mention, we had x86-64 systems for free, and we had to pay for everything else). This eliminated the need for such dedicated hardware, and in practice the years it was in use I believe it eliminated issues in compatibility with non-x86-64 architectures and also helped catch problems in new code (such as alignment issues). For an upstream test suite it was totally worth it, and I believe it eliminated all issues we were getting with non-x86 hardware support. The only drawback that was noticed is that it could not be used to test some special features of these CPUs, but that's also a problem with dedicated hardware (e.g., when it doesn't support the particular instruction set you'd like to introduce). regards, Nikos [0]. https://gitlab.com/gnutls/gnutls/-/blob/master/.gitlab-ci.yml#L718 _______________________________________________ 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
