Subject: [v6 0/8] 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:
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)
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.
Feng Wu (7):
iommu: Add new member capability to struct irq_remap_ops
iommu, x86: Implement irq_set_vcpu_affinity for intel_ir_chip
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
