  intel_iommu: Add support for PCI MSI remap

This patch enables interrupt remapping for PCI devices.

To play the trick, one memory region "iommu_ir" is added as child region
of the original iommu memory region, covering range 0xfeeXXXXX (which is
the address range for APIC). All the writes to this range will be taken
as MSI, and translation is carried out only when IR is enabled.

Idea suggested by Paolo Bonzini.

it will be system memory address space. When IR is enabled, it will be
IOMMU address space.

Currently, only emulated IOAPIC is supported.

  intel_iommu: add support for split irqchip

In split irqchip mode, IOAPIC is working in user space, only update
kernel irq routes when entry changed. When IR is enabled, we directly
update the kernel with translated messages. It works just like a kernel
cache for the remapping entries.

Since KVM irqfd is using kernel gsi routes to deliver interrupts, as
long as we can support split irqchip, we will support irqfd as
well. Also, since kernel gsi routes will cache translated interrupts,
irqfd delivery will not suffer from any performance impact due to IR.

And, since we supported irqfd, vhost devices will be able to work
seamlessly with IR now. Logically this should contain both vhost-net and
vhost-user case.

  x86-iommu: introduce IEC notifiers

This patch introduces x86 IOMMU IEC (Interrupt Entry Cache)
invalidation notifier list. When vIOMMU receives IEC invalidate
request, all the registered units will be notified with specific
invalidation requests.

Intel IOMMU is the first provider that generates such a event.

  ioapic: register IOMMU IEC notifier for ioapic

Let IOAPIC the first consumer of x86 IOMMU IEC invalidation
notifiers. This is only used for split irqchip case, when vIOMMU
receives IR invalidation requests, IOAPIC will be notified to update
kernel irq routes. For simplicity, we just update all IOAPIC routes,
even if the invalidated entries are not IOAPIC ones.

Since now we are creating IOMMUs using "-device" parameter, IOMMU
device will be created after IOAPIC.  We need to do the registration
after machine done by leveraging machine_done notifier.

  intel_iommu: Add support for Extended Interrupt Mode

As neither QEMU nor KVM support more than 255 CPUs so far, this is
simple: we only need to switch the destination ID translation in
vtd_remap_irq_get if EIME is set.

Once CFI support is there, it will have to take EIM into account as
well. So far, nothing to do for this.

This patch allows to use x2APIC in split irqchip mode of KVM.

  kvm-irqchip: simplify kvm_irqchip_add_msi_route

Changing the original MSIMessage parameter in kvm_irqchip_add_msi_route
into the vector number. Vector index provides more information than the
MSIMessage, we can retrieve the MSIMessage using the vector easily. This
will avoid fetching MSIMessage every time before adding MSI routes.

Meanwhile, the vector info will be used in the coming patches to further
enable gsi route update notifications.

  kvm-irqchip: i386: add hook for add/remove virq

Adding two hooks to be notified when adding/removing msi routes. There
are two kinds of MSI routes:

- in kvm_irqchip_add_irq_route(): before assigning IRQFD. Used by
  vhost, vfio, etc.

- in kvm_irqchip_send_msi(): when sending direct MSI message, if
  direct MSI not allowed, we will first create one MSI route entry
  in the kernel, then trigger it.

This patch only hooks the first one (irqfd case). We do not need to
take care for the 2nd one, since it's only used by QEMU userspace
(kvm-apic) and the messages will always do in-time translation when
triggered. While we need to note them down for the 1st one, so that we
can notify the kernel when cache invalidation happens.

Also, we do not hook IOAPIC msi routes (we have explicit notifier for
IOAPIC to keep its cache updated). We only need to care about irqfd
users.

Since both vfio and vhost are possible gsi route consumers, this patch
will go one step further to keep them safe in split irqchip mode and
when irqfd is enabled.
