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:

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
