With VT-d Posted-Interrupts enabled, external interrupts from direct-assigned devices can be delivered to guests without VMM intervention when guest is running in non-root mode. You can find the VT-d Posted-Interrtups Spec. in the following URL: http://www.intel.com/content/www/us/en/intelligent-systems/intel-technology/vt-directed-io-spec.html This series was part of http://thread.gmane.org/gmane.linux.kernel.iommu/7708. To make things clear, send out IOMMU part here. This patch-set is based on the lastest x86/apic branch of tip tree. Divide the whole series which contain multiple components into three parts: - Prerequisite changes to irq subsystem (already merged in tip tree x86/apic branch) - IOMMU part (in this series) - KVM and VFIO parts (will send out this part once the first two parts are accepted) v6->v7: * Add an static inline helper function set_irq_posting_cap() to set the PI capability. * Add some comments for the new member "ir_data->irte_pi_entry". v5->v6: * Extend 'struct irte' for VT-d Posted-Interrupts, combine remapped and posted mode into one irte structure. v4->v5: * Abstract modify_irte() to accept two format of irte. v3->v4: * Change capability to a int variant flags instead of a function call. * Add hotplug case for VT-d PI.
