Run Rocky10 on x86_64-v2, x86_64-v1 initiative AltArch
Hello,
RockyLinux is a great project, but unfortunately, newer versions reduce the hardware support, in contrast to Debian, which runs on older hardware as well as on the newest.
I’m proposing to do a rebuild… Answer from tjdoyle on forums.rockylinux.org

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.

It is possible to complete the installation with less memory than the minimum requirements. The exact requirements depend on your environment and installation path. Test various configurations to determine the minimum required RAM for your environment. Installing Red Hat Enterprise Linux using a Kickstart file has the same minimum RAM requirements as a standard installation.

January 3, 2024 - 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.

I'd expect CPUs to provide at least the AVX-512 functionality, even if it's (also) exposed through AVX10. AVX10 changed just enough that I think you can make a CPU with AVX10/512 that's incompatible with v4. Intel's server CPUs look set to continue implementing AVX-512, in addition to AVX10, ...

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.
