configuration/OS/software for Xeon CPU MAX server?

[CFR]

It looks like I'm going to be getting access to a Xeon CPU MAX server to experiment with (mostly to evaluate enabling applications for HBM).  Given it's fairly new and the HBM is not a common feature I started wondering what, if any, things I should be looking for in terms of software (primarily OS) install.  The server vendor just has the CPU MAX listed as one of many CPU options and say "RedHat 8.6/9.0".  Intel has https://www.intel.com/content/www/us/en/content-details/787743/intel-xeon-cpu-max-series-configuration-and-tuning-guide.html which recommends the "latest stable kernel (currently 5.15)" but further sections list a few features that require newer (5.16, 6.1, etc...) kernels.

My sysadmins are going to want to put RedHat 9 on it, and as best as I can tell that means a 5.14 kernel.  About the only thing I was able to find regarding RedHat supporting "CPU MAX" processors was: https://catalog.redhat.com/hardware/components/detail/234257

So, does anyone have experience with such a system and some suggestions on how to set it up?

Thanks.  I'm not really sure this is specifically a question for Intel, but as this is supposed to be an "community" forum I'm hoping may some other user's might have some related experience.  I'll take all the help I can get.

Hello CFR,

Greetings for the day!

Please note that HBM allows kernel 5.16 access without additional DAX commands, enabling visibility of HBM nodes post-boot. However, this action reserves a small portion of HBM memory from each NUMA node for metadata storage.

For more details please find the attached link:

For optimal utilization of HBM in Red Hat Enterprise Linux, considering the specific features of CPU MAX, We recommend reaching out to the Red Hat community or support.

Best regards,

I haven't found any authoritative documents on OS support (especially RedHat 9) but I did stumble across the following which looks useful...
