[Qemu-devel] [RFC PATCH 0/6] vITS support

[Pavel Fedin]

This series introduces support for in-kernel GICv3 ITS emulation.
It is based on kernel API which is not released yet, therefore i post it
as an RFC. However, if respective maintainers think this is appropriate,
infrastructure-related parts of this set (patch N1 and parts of patch N4)
can be applied right now, in order to simplify future addition.

Kernel patches which implement this functionality are:
- [PATCH v2 00/15] KVM: arm64: GICv3 ITS emulation
  http://www.spinics.net/lists/arm-kernel/msg430724.html
- [PATCH v3 0/7] KVM: arm/arm64: gsi routing support
  http://www.spinics.net/lists/kvm/msg119567.html

Pavel Fedin (6):
  kvm: Make KVM_CAP_SIGNAL_MSI globally available
  hw/intc: Implement ITS base class
  Add vGICv3 ITS definitions
  kvm: Implement passing device ID to MSI routing functions
  kvm_arm: Implement support for ITS emulation by KVM
  arm/virt: Add ITS to the virt board
