From 3cd60e31185343d4132ca7cf3c9becb903b3ec1b Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Wed, 4 Jun 2014 16:47:55 +0530 Subject: KVM: PPC: BOOK3S: PR: Fix PURR and SPURR emulation We use time base for PURR and SPURR emulation with PR KVM since we are emulating a single threaded core. When using time base we need to make sure that we don't accumulate time spent in the host in PURR and SPURR value. Also we don't need to emulate mtspr because both the registers are hypervisor resource.
