It seems that qemu says guest that it support tsc_deadline when it is not supported in reality. See patch defcf51fa93929bd5d3ce5b91f8e6a106dae5e46, it always say 'yes'. diff --git a/target-i386/kvm.c b/target-i386/kvm.c index 41d09e5..8a56272 100644 --- a/target-i386/kvm.c +++ b/target-i386/kvm.c @@ -217,14 +217,6 @@ uint32_t kvm_arch_get_supported_cpuid(KVMState *s, uint32_t function, * GET_SUPPORTED_CPUID */ ret |= CPUID_EXT_HYPERVISOR; - /* tsc-deadline flag is not returned by GET_SUPPORTED_CPUID, but it - * can be enabled if the kernel has KVM_CAP_TSC_DEADLINE_TIMER, - * and the irqchip is in the kernel. - */ - if (kvm_irqchip_in_kernel() && - kvm_check_extension(s, KVM_CAP_TSC_DEADLINE_TIMER)) { - ret |= CPUID_EXT_TSC_DEADLINE_TIMER; - } /* x2apic is reported by GET_SUPPORTED_CPUID, but it can't be enabled * without the in-kernel irqchip -- You are receiving this mail because: You are on the CC list for the bug.
