Since CentOS is heavily used on Numascale systems, it would be a great enabler to have CONFIG_NUMACHIP enabled in CentOS kernels.
It has been enabled for some time in Ubuntu server kernels.
What else is needed to request this?
Many thanks, Daniel
This can not happen on the main CentOS distro kernels unless that option is on in RHEL as we rebuild our kernel to have the same options as that kernel.
However, we have a CentOS Plus kernel where optional things are turned on.
That option (CONFIG_NUMACHIP) is not in the CentOS-6 kernel ... But ... CONFIG_NUMA is on in the CentOS-6 plus kernel.
In the CentOS-7 kernel-plus config, CONFIG_X86_NUMACHIP is off and CONFIG_NUMACHIP does not exist. So, I would say that this is not possible without patches. If you, or someone else, is doing this on CentOS and is making special kernels, this is the place for a discussion and possible kernel for this option.
