From: Gleb Natapov Date: Sun, 9 Aug 2009 12:17:40 +0000 (+0300) Subject: KVM: Update cr8 intercept when APIC TPR is changed by userspace X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cb142eb743d02d48165c9d941b601d731cc4a003;p=linux-beck.git KVM: Update cr8 intercept when APIC TPR is changed by userspace Since on vcpu entry we do it only if apic is enabled we should do it when TPR is changed while apic is disabled. This happens when windows resets HW without setting TPR to zero.
