These systems would still benefit from a 32-bit kernel. For reference, the last CPU I used that didn’t have SSE2 support was an Athlon XP - introduced to compete with the P4 but actually had the instruction set of a PIII more or less. I remember this because I tried to run OpenSolaris on it. Which even about 15 years ago, required SSE2 How about instead of proposing to drop support for anything not using x86-64 this was pushed as a proposal to stop supporting anything that doesn’t do SSE2 (which seems to be the actual proposal) - does it sound any different now? To me, it does - because I’d suspect P4 and some Atom chips covers quite a range of hardware that people still use. Whether it’s worth running such a P4 machine nowadays is another question of course, given how power hungry they are for not much compute power... To me? It’s perhaps worth dropping non-SSE2 support but i wouldn’t stop building kernels for 32-bit Michael _______________________________________________ > devel mailing list -- devel@lists.fedoraproject.org > To unsubscribe send an email to devel-le...@lists.fedoraproject.org > Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html > List Guidelines: > https://fedoraproject.org/wiki/Mailing_list_guidelines> List Archives: > https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/message/ZZ65EEUBDU7YHBUYKQ2X5IYX7KSSTDID/> > Email had 1 attachment: > + signature.asc > 1k (application/pgp-signature)
