Subject: [Qemu-devel] [PATCH] Add VT-d Posted-Interrupts support in QEMU
Date: Mon, 10 Nov 2014 14:31:16 +0800 [thread overview]
Message-ID: <1415601077-27890-1-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.
This patch is used together with the patches in KVM side.
You can find the VT-d Posted-Interrtups Spec. in the following URL:
