From: Yang Zhang <[email protected]> Current interrupt coalescing logci which only used by RTC has conflict with Posted Interrupt.
This patch introduces a new mechinism to use eoi to track interrupt: When delivering an interrupt to vcpu, the need_eoi set to number of vcpu that received the interrupt. And decrease it when each vcpu writing eoi. No subsequent RTC interrupt can deliver to vcpu until all vcpus write eoi. Yang Zhang (5): KVM: parse ioapic entry to get destination vcpu KVM: add vcpu info to ioapic_update_eoi() KVM: introduce struct rtc_status KVM: register rtc eoi notifier KVM: use eoi to track RTC interrupt delivery status arch/x86/kvm/lapic.c | 44 +++++++++------ arch/x86/kvm/lapic.h | 4 ++ virt/kvm/ioapic.c | 143 +++++++++++++++++++++++++++++++++++++++++++++++-- virt/kvm/ioapic.h | 12 ++++- 4 files changed, 178 insertions(+), 25 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
