From 1a171608ee8d40d22d604303e42f033c69151123 Mon Sep 17 00:00:00 2001 From: Tony Luck Date: Fri, 28 Jun 2024 14:56:05 -0700 Subject: x86/resctrl: Add node-scope to the options for feature scope Currently supported resctrl features are all domain scoped the same as the scope of the L2 or L3 caches. Add RESCTRL_L3_NODE as a new option for features that are scoped at the same granularity as NUMA nodes. This is needed for Intel's Sub-NUMA Cluster (SNC) feature where monitoring features are divided between nodes that share an L3 cache.
