Subject: [PATCH 1/6] qemu,kvm:  Enable NMI support for user space irqchip
Date: Thu, 09 Dec 2010 14:58:52 +0800	[thread overview]
Message-ID: <4D007E2C.4070308@cn.fujitsu.com> (raw)


Make use of the new KVM_NMI IOCTL to send NMIs into the KVM guest if the
user space APIC emulation or some other source raised them.
