[elrepo] AMD EPYC Support

[nick at ramnode.com]

Thanks Dave. What do you think about trying kernel-ml on CentOS 6? We’re trying to do a direct swap of Intel for AMD without disrupting the existing systems (CentOS 6/kernel-lt el6 running KVM). Hoping to keep changes down to just reconfiguring networking.

 

Regards,

Nick

As hardware support is accomplished primarily through the kernel, and you've likely replaced it with an elrepo kernel the Redhat documentation would not apply.  Additionally since Epyc is such a new processor you might have better luck running the kernel-ml instead of the kernel-lt as large driver backports are typically not accepted according to the linux-stable rules.

 

If I were you and intent on running an Epyc machine I'd move up to cent 7 + the kernel-ml, or move to Ubuntu Bionic which has a 4.15 kernel where they may have attempted to backport some of the Epyc enablement.

 

Good luck,

Dave.

Hello,

 

Has anyone tried running kernel-lt 4.4 (el6) on AMD EPYC processors? RedHat documentation seems to indicate that RHEL/CentOS 6 is not supported on the EPYC lineup, but AMD’s documentation is unclear.

 

Regards,

Nick
