From b33ac88b4c23330043acad930517282eb486db1d Mon Sep 17 00:00:00 2001 From: Kevin Pedretti Date: Sun, 21 Oct 2007 08:54:53 +0200 Subject: [PATCH] KVM: Fix local apic timer divide by zero kvm_lapic_reset() was initializing apic->timer.divide_count to 0, which could potentially lead to a divide by zero error in apic_get_tmcct(). Any guest that reads the APIC's CCR (current count) register before setting DCR (divide configuration) would trigger a divide by zero exception in the host kernel, leading to a host-OS crash. This patch results in apic->timer.divide_count being initialized to 2 at reset, eliminating the bug (DCR=0 at reset, meaning divide by 2).
