Category: qemu Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Aron Griffis (agriffis) Assigned to: Nobody/Anonymous (nobody) Summary: segfault using -cpu pentium3 on coreduo Initial Comment: qemu-0.11.0-rc1 and qemu-kvm-HEAD segfault with -cpu pentium3 on ProLiant DL380 G5 (dual-socket dual-core Intel Xeon 5160). This is a regression from qemu-0.10.6 which does not have the problem. Using -cpu coreduo avoids the segfault. -cpu athlon works too. I bisected to find that the problem is introduced by 0ed8cfc05bb012e52b92771bb13bef0e2e80c828 and can be worked around by the following patch to HEAD which effectively reverts that commit: --- a/hw/pc.c +++ b/hw/pc.c @@ -1096,11 +1096,11 @@ CPUState *pc_new_cpu(const char *cpu_model) } if ((env->cpuid_features & CPUID_APIC) || smp_cpus > 1) { env->cpuid_apic_id = env->cpu_index; - /* APIC reset callback resets cpu */ - apic_init(env); } else { qemu_register_reset((QEMUResetHandler*)cpu_reset, env); } + /* APIC reset callback resets cpu */ + apic_init(env); /* kvm needs this to run after the apic is initialized. Otherwise, * it can access invalid state and crash. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=893831&aid=2835276&group_id=180599 -- 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
