Subject: [PATCH v6 00/18] Add VT-d Posted-Interrupts support
Date: Tue, 25 Aug 2015 09:57:39 +0800	[thread overview]
Message-ID: <1440467877-5116-1-git-send-email-feng.wu@intel.com> (raw)

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


Feng Wu (18):
  VT-d Posted-intterrupt (PI) design
  Add cmpxchg16b support for x86-64
  iommu: Add iommu_intpost to control VT-d Posted-Interrupts feature
  vt-d: VT-d Posted-Interrupts feature detection
  vmx: Extend struct pi_desc to support VT-d Posted-Interrupts
  vmx: Add some helper functions for Posted-Interrupts
  vmx: Initialize VT-d Posted-Interrupts Descriptor
  vmx: Suppress posting interrupts when 'SN' is set
  VT-d: Remove pointless casts
  vt-d: Extend struct iremap_entry to support VT-d Posted-Interrupts
  vt-d: Add API to update IRTE when VT-d PI is used
  x86: move some APIC related macros to apicdef.h
  Update IRTE according to guest interrupt config changes
  vmx: posted-interrupt handling when vCPU is blocked
  vmx: Properly handle notification event when vCPU is running
  vmx: Add some scheduler hooks for VT-d posted interrupts
  VT-d: Dump the posted format IRTE
  Add a command line parameter for VT-d posted-interrupts
