    For Linux usage, you're most likely going to need a much newer Linux Kernel. Centmin Mod is getting close on EL8 compatibility. But EL8 is only 4.18 Linux Kernel and EL9 compatibility is much further off and then only has 5.14 Linux Kernel. Probably for AMD Ryzen 7000 Zen4 on Linux, you'd need 5.19/6.0 Linux Kernels eventually. Will be interesting to see how ELRepo Linux mainline Kernels fair.

    Zen 4-based EPYC server processors codenamed Genoa and Bergamo are not yet released.
    Ryzen 5 and 7 is consumer based hardware.

    There is no need to use external kernels.
    Red Hat has a policy of backporting hardware support to existing Enterprise Linux products in the full support phase. Provided the software is not in the Maintenance phase. That would mean that EL9 gets Zen 4 support and EL8 depending on whether it is just out of phase then. Or just in it, when the code can be ready. The full support phase is 5 years. EL8 is almost 3.5 years old. EL8 has previously received backport Zen3 support.

    Good to know, though depends. In the past at least for CentOS 7 with 3.10 even in active support phase, it was lagging behind for AMD Ryzen/Zen support the beginning of each generations' launches.

    Of course it's an enterprise product. Stability and quality before quantity.
    New hardware gives quite a bit of test work.
    And for certified hardware, you're even longer. Before you get that certification.

    Officially, (RH)EL only runs on certified hardware.
    Anything beyond that is at your own risk. With no guarantees.

    Well here's to EL8 and EL9 having better compatibility. At least backport this fix A 20 Year Old Chipset Workaround Has Been Hurting Modern AMD Linux Systems - Phoronix :)

    Relatively good news regarding Spectre/RetBleed security mitigaton overhead in Linux Kernels With AMD Zen 4, It's Surprisingly Not Worthwhile Disabling CPU Security Mitigations - Phoronix

    Will be interesting to see how Intel 13th Generation Raptor Lake handles such mitigations being enabled :)
