What:	KVM paravirt mmu host support

When:	January 2011

Why:	The paravirt mmu host support is slower than non-paravirt mmu, both

	on newer and older hardware.  It is already not exposed to the guest,

	and kept only for live migration purposes.

4.64 KVM_NMI



Capability: KVM_CAP_USER_NMI

Architectures: x86

Type: vcpu ioctl

Parameters: none

Returns: 0 on success, -1 on error



Queues an NMI on the thread's vcpu.  Note this is well defined only

when KVM_CREATE_IRQCHIP has not been called, since this is an interface

between the virtual cpu core and virtual local APIC.  After KVM_CREATE_IRQCHIP

has been called, this interface is completely emulated within the kernel.



To use this to emulate the LINT1 input with KVM_CREATE_IRQCHIP, use the

following algorithm:



  - pause the vpcu

  - read the local APIC's state (KVM_GET_LAPIC)

  - check whether changing LINT1 will queue an NMI (see the LVT entry for LINT1)

  - if so, issue KVM_NMI

  - resume the vcpu



Some guests configure the LINT1 NMI input to cause a panic, aiding in

debugging.
