Subject[v9 0/9] Add VT-d Posted-Interrupts support - IOMMU part
VT-d Posted-Interrupts is an enhancement to CPU side Posted-Interrupt.
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:

This series was part of 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)

* Remove member "irte_pi_entry" in struct intel_ir_data.
* Some changes to the comments.

* Save the irq mode (posted or remapped) of an IRTE in struct irq_2_iommu.
* Use this new mode to decide whether update the hardware when
modifying irte in intel_ir_set_affinity().

* 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".

* Extend 'struct irte' for VT-d Posted-Interrupts, combine remapped
and posted mode into one irte structure.

* Abstract modify_irte() to accept two format of irte.

* Change capability to a int variant flags instead of a function call.
* Add hotplug case for VT-d PI.

Feng Wu (8):
iommu: Add new member capability to struct irq_remap_ops
iommu, x86: Implement irq_set_vcpu_affinity for intel_ir_chip
iommu, x86: Save the mode (posted or remapped) of an IRTE
iommu, x86: No need to migrating irq for VT-d Posted-Interrupts
iommu, x86: Add cap_pi_support() to detect VT-d PI capability
iommu, x86: Setup Posted-Interrupts capability for Intel iommu
iommu, x86: define irq_remapping_cap()
iommu, x86: Properly handler PI for IOMMU hotplug

Thomas Gleixner (1):
iommu: dmar: Extend struct irte for VT-d Posted-Interrupts
