Subject: [v4 00/17] Add VT-d Posted-Interrupts support
Date: Thu, 23 Jul 2015 19:35:36 +0800 [thread overview]
Message-ID: <1437651353-5275-1-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
This patch set follow the following design:

Feng Wu (17):
VT-d Posted-intterrupt (PI) design
Add helper macro for X86_FEATURE_CX16 feature detection
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: Extend struct iremap_entry to support VT-d Posted-Interrupts
vt-d: Add API to update IRTE when VT-d PI is used
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
arm: add a dummy arch hooks for scheduler
vmx: Add some scheduler hooks for VT-d posted interrupts
VT-d: Dump the posted format IRTE
