Subject: [PATCH v9 00/17] Add VT-d Posted-Interrupts support
Date: Tue, 3 Nov 2015 16:43:10 +0800 [thread overview]
Message-ID: <1446540207-4806-1-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
v9:
- [PATCH v9 01/17] VT-d Posted-intterrupt (PI) design
* Make the description more generic.
- [PATCH v9 02/17] Add cmpxchg16b support for x86-64
* Make the *ptr operand an input and output.
- [PATCH v9 15/17] vmx: VT-d posted-interrupt core logic handling
* Remove arch_vcpu_block_cancel() and arch_vcpu_wake_prepare().
* Add vmx_pi_state_change() and call it before VM Entry.
