Message-Id: <1403101279-23759-1-git-send-email-namit@cs.technion.ac.il> Date: Wed, 18 Jun 2014 17:21:19 +0300 From: Nadav Amit <namit@...technion.ac.il> To: pbonzini@...hat.com Cc: gleb@...nel.org, tglx@...utronix.de, mingo@...hat.com, hpa@...or.com, x86@...nel.org, linux-kernel@...r.kernel.org, kvm@...r.kernel.org, Nadav Amit <namit@...technion.ac.il> Subject: [PATCH] KVM: x86: Increase the number of fixed MTRR regs to 10 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.
