Hey all,
Earlier this week, I was helping with processing features for openSUSE
Leap 15.4[1] and I discovered that they're planning on introducing
x86_64-v2 to openSUSE soon. The reference for this change was that
RHEL 9 is going to use x86_64-v2[2]. Additionally, other distributions
have been considering bumping up to v2 or v3[3][4].
Some cursory examination of the new x86_64 sublevels seem to indicate
that x86_64-v2 goes back to roughly 2007~2008, merely cutting off the
first couple of generations of x86_64 CPUs from Intel and AMD. I
personally don't have any computers that don't have support for
x86_64-v2 anymore.
Yes, you loose primarily Intel Conroe and Penryn generations and
AMD Opteron Gen 1 -> Gen 3. I doubt this is a significant portion
of Fedora installs.
Slight tangent but I find Fedora's approach to hardware somewhat
at odds with our approach to software.
On the one hand we portray our project as a place for cutting
edge Linux software & innovation.
On the other hand we hold back our software by trying to keep
supporting long obsolete hardware.
There is of course always a balance between bumping min hardware
specs and the impact on maintainers & users, but I'm not convinced
that we have the balance right in targeting our x86_64 baseline at
the very first generation of 64-bit CPUs from 15 years ago. I can't
imagine such old CPUs makes up a significant portion of our users.
Regards,
Daniel
