r/linux on Reddit: PSA: RHEL 10 and Clones/Forks Require a x86-64-v3 Processor.
February 21, 2024 -
For anyone who uses RHEL or any of its clones (now forks, rather), beware that version 10 already does require a x86-64-v3 capable CPU.
I discovered this by accident while I tried to test CentOS Stream 10 on VirtualBox, which does not expose my processor’s more advanced features to the VMs.
As I tried to boot the installer I got the error: “The CPU does not support x86-64-v3”.
This change will of course be present on all CentOS Stream 10 clones and/or forks like Alma and Rocky 10, all due out in 2025.
I say this because I know there are many folks out there who run CentOS/Alma/Rocky on older hardware…

I discovered this by accident while I tried to test CentOS Stream 10 on VirtualBox, which does not expose my processor’s more advanced features to the VMs. If you have a CPU that supports certain features and VirtualBox isn't exposing it, try libvirt or xen instead. By the way, it's possible that RHEL 10's x86-64-v3 support will be scrapped in favor of a proposed new system in Fedora that makes use of glibc-hwcaps and symlinks to continue to provide a fallback. But it's also possible they will eventually adopt the -v3 baseline and only use hwcaps for -v4. Plenty of RHEL 9 support left and other distros to choose from if that is the case.

Red Hat Evaluating x86-64-v3 Requirement For RHEL 10 - Phoronix
Red Hat Enterprise Linux 9 requires x86-64-v2 while for Red Hat Enterprise Linux 10 they are looking at upping things to x86-64-v3 that would basically mandate Intel and AMD processors with AVX/AVX2 support. This roughly translates to Intel Haswell era processors or AMD Excavator era CPUs and newer.

January 3, 2024 - Even if we cannot show performance improvements for software included in RHEL, it may still make sense to go ahead with the switch. The reason is that if RHEL 10 requires the x86-64-v3 baseline, ISVs will be able to rely on it, too.

r/linux on Reddit: CentOS Stream 10 / RHEL 10 are seemingly going to drop support for older Intel processors.
April 7, 2024 -
This news only concerns those of us who are interested in running RHEL or CentOS Stream on our home labs and we happen to use one of these CPUs.
Today I went to test CentOS Stream 10 which requires x86_64-v3 at minimum, and is based on Fedora 40.
I was surprised to see a warning message about my X86_64-V4-CAPABLE Intel Core i5-11400 CPU being detected as DEPRECATED hardware, and that it would be disabled on a future major release.
I know RHEL 10 is still over a year away but this is just a heads up.
— Again: All Intel Rocket Lake processors are x86_64-v4 capable, which puts them way above the CPU requirements for RHEL 10/CentOS 10.
Edit: After more reading and more careful consideration, I came to the conclusion that this simply does not make sense and must be a bug. The i5-11400 is by no means an ancient CPU. It’s from 2021 and it makes no sense for Red Hat to just deprecate it.

from a RedHat employee who replied to this in the RedHat subreddit - "Hey! Just a note about how deprecations work in RHEL, we declare something 'deprecated' but continue to enable it for the life of a major release and reserve the right to remove functionality in a future major release. Since this CPU supports x86_64-v3, you should be alright but to be clear we are indeed advancing the baseline to v3 for RHEL 10."

You posted this on r/redhat and then immediately posted it here. On a Saturday. About what is effectively a beta of CentOS Stream. I’m actually a bit surprised Brian answered at all, but good on him for doing so. But, you know, maybe next time give a reasonable amount of time for people who might know to answer? Instead of posting to rile people up? I don’t know for certain either, but it’s very likely a mistake if that is a desktop CPU from 2021.

I just checked and out of my six current computers there’s only one (laptop) that has X86-64-v3. ☹ I might have to start considering my options if this actually goes ahead.
