Hi, I noticed that commit 50a2c6e55fa2ce5a2916a2c206bad2c6b0e06df1 broke KVM/ARM, because the realize function (arm_cpu_realizefn()) now calls cpu_reset() before qemu_init_vcpu(), which causes kvm_arm_reset_cpu() to segfault because it dereferences cpu->cpreg_reset_values, which is not allocated before kvm_arch_init_vcpu(). Simply changing the order of the reset/init calls (see the tiny patch below) seems to fix it, but I'm not completely sure this is a clean and correct fix: diff --git a/target-arm/cpu.c b/target-arm/cpu.c index 6c6f2b3..794dcb9 100644 --- a/target-arm/cpu.c +++ b/target-arm/cpu.c @@ -370,8 +370,8 @@ static void arm_cpu_realizefn(DeviceState *dev, Error **errp) init_cpreg_list(cpu); - cpu_reset(cs); qemu_init_vcpu(cs); + cpu_reset(cs); acc->parent_realize(dev, errp); } Please adivce :) Thanks, -Christoffer -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
