[Xen-devel] [PATCH v10 0/7] Add VT-d Posted-Interrupts support

[Feng Wu <feng.wu@xxxxxxxxx>]

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 (17):
 r   VT-d Posted-intterrupt (PI) design
 ra  vmx: Suppress posting interrupts when 'SN' is set
 r   vt-d: Add API to update IRTE when VT-d PI is used
  a  Update IRTE according to guest interrupt config changes
  a  vmx: Properly handle notification event when vCPU is running
     vmx: VT-d posted-interrupt core logic handling
 ra  Add a command line parameter for VT-d posted-interrupts
 
 r = has been 'Reviewed-by'
 a = has been 'Acked-by'
