Could you please help me understand the details by answering my first question: What is the use case for needing to expose the individual cluster counts?
This is a model specific feature so if this is something needed for just a couple of systems I think we should be less inclined to make changes to resctrl interface. I am starting to be concerned about something similar becoming architectural later and then we need to wrangle this model specific resctrl support (which has then become ABI) again to support whatever that may look like.
Reinette,
Model specific. But present in multiple consecutive generations (Sapphire Rapids, Emerald Rapids, Granite Rapids, Sierra Forest).
Adding Peter Newman for a resctrl user perspective on SNC, rather than me continue to speculate on possible ways this might be used.
Peter: You will need to dig back a few messages on lore.kernel.org to get context.
