For myself, i found that building = packages on poudriere running in native arm64 servers is way more = efficient compared to qemu on amd64, and now I am running the full build = on Azure instance. I know that we are using some arm64 build servers, = happy to contribute to having armv6/armv7 builds running on them. The standard FreeBSD kernel for arm64 also supports armv7 (if the hardware does) but not armv6. You can look via: # sysctl kern.supported_archs (But checking for the hardware actually supporting armv7 seems to be recent for contributing to the text generated so armv7 may be falsely claimed. armv6 will not be listed.) See: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D256132#c13 for a suggested way of have FreeBSD support both armv7 and armv6 at the same time. (That is comment #13.) But that would have an implementation effort first. There is an existing way to change a #define and build a kernel that supports armv6 instead of armv7. See the earlier comment #11: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D256132#c11 I'll note that I've not done such since lib32 support for armv7 was added. armv6 lib32 was not added so using a non-lib32 build of world might be required. poudriere just requires the jail/chroot sort of support for armv6, not lib32 support. The FreeBSD build servers ( ampere[1-3] ) are not booted with such special kernels (or worlds). But they do build armv7 on arm64. armv7 also used to be built via qemu on amd64 and had the same sorts of problems back then that armv6 still has. If you read my other notes in: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D256132 be aware that some later notes correct my errors in my earlier notes, making for a messy read. =3D=3D=3D Mark Millard marklmi at yahoo.com
