Babu, My original patch series added an "snc_ways" file to the info/ directory to make this visible. But I was talked out of it because of a lack of clear user mode use case that needs it. https://lore.kernel.org/all/f0841866-315b-4727-0a6c-ec60d22ca29c@xxxxxxx/ Users can figure out whether SNC is enabled by looking at topology files for nodes and L3 caches in /sys. The open question is whether we should provide a simple short cut to that information, or make them walk two miles uphill in the snow to figure it out. -Tony
