From 98af74599ea0757098a5776ea29e581b661dcf6f Mon Sep 17 00:00:00 2001 From: Len Brown Date: Sat, 21 Jan 2017 01:15:09 -0500 Subject: [PATCH] x86 msr_index.h: Define MSR_MISC_FEATURE_CONTROL This non-architectural MSR has disable bits for various prefetchers on modern processors. While these bits are generally touched only by the BIOS, say, via BIOS SETUP, it is useful to dump them when examining options that can alter performance.
