NumaChip kernel config option

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.

Indeed, I meant CONFIG_X86_NUMACHIP. I'll see what can be done upstream
with RHEL7.x or so in the medium term.

That would certainly help. Let me know if a Bugzilla entry or otherwise
is needed to request it.

I suspect CONFIG_X86_NUMACHIP is what the OP meant ... (and enabled in Ubuntu).
