Subject: [PATCH] x86/intel_rdt: Classify /proc/cpuinfo flag bits and add missing bits in documentation
Date: Fri, 8 Dec 2017 16:25:02 -0800 [thread overview]
Message-ID: <1512779102-45295-1-git-send-email-fenghua.yu@intel.com> (raw)
From: Fenghua Yu <fenghua.yu@intel.com>
With more flag bits in /proc/cpuinfo for RDT, it's better to classify the
bits for readability.
Some previously missing bits are added as well.

This feature is enabled by the CONFIG_INTEL_RDT Kconfig and the
-X86 /proc/cpuinfo flag bits "rdt", "cqm", "cat_l3" and "cdp_l3".
+X86 /proc/cpuinfo flag bits:
+RDT (Resource Director Technology) Allocation - "rdt_a"
+CAT (Cache Allocation Technology) - "cat_l3", "cdp_l3", "cat_l2"
+CQM (Cache QoS Monitoring) - "cqm_llc", "cqm_occup_llc"
+MBM (Memory Bandwidth Monitoring) - "cqm_mbm_total", "cqm_mbm_local"
+MBA (Memory Bandwidth Allocation) - "mba"
