This patchset implements qemu device model for enabling physical LPI support and ITS functionality in GIC as per GICv3 specification. Both flat table and 2 level tables are implemented.The ITS commands for adding/deleting ITS table entries,trigerring LPI interrupts are implemented.Translated LPI interrupt ids are processed by redistributor to determine priority and set pending state appropriately before forwarding the same to cpu interface. The ITS feature support has been added to sbsa-ref platform as well as virt platform,wherein the emulated functionality co-exists with kvm kernel functionality.
