From 16f225f355b19890d4e09b345c3fd85496fa4c66 Mon Sep 17 00:00:00 2001 From: Nadav Amit Date: Wed, 18 Jun 2014 17:21:19 +0300 Subject: KVM: x86: Increase the number of fixed MTRR regs to 10 commit 682367c494869008eb89ef733f196e99415ae862 upstream. Recent Intel CPUs have 10 variable range MTRRs. Since operating systems sometime make assumptions on CPUs while they ignore capability MSRs, it is better for KVM to be consistent with recent CPUs. Reporting more MTRRs than actually supported has no functional implications.
