I'm not hitting any issues. AMD's APU is a new kind of processing device, which integrates a CPU and a GPU on the same die. I want to know whether Xen has supported the virtualization of the APU processors? If yes, I can run something applications in the Xen PV VMs to use this kind of new CPU device. Something information about the AMD' APU: http://en.wikipedia.org/wiki/Accelerated_processing_unit http://blog.netflowdevelopments.com/2012/05/03/what-is-an-apu/ http://www.amd.com/us/products/technologies/fusion/Pages/fusion.aspx Best Regards, Bei Guan 2012/9/11 Konrad Rzeszutek Wilk <konrad@kernel.org> > On Mon, Sep 10, 2012 at 08:48:41PM +0800, Bei Guan wrote: > > Hi, > > > > Is there any news or plan about Xen support the latest AMD hardware APU > > (Accelerated Processing Unit)?

AFAIK at this point AMD APUs are simply CPU + GPU. Even though they're in the same die, they're basically different devices. So for the GPU part, treat it like any other GPU. Which means you could PROBABLY passthru it to ONE domU, but that's it. AMD's plan for the future is make a chip which can function as CPU or GPU as needed, but that hasn't happened yet. -- Fajar ^ permalink raw reply [flat|nested] 6+ messages in thread

However, the GPU is exclusively used by a VM in this way. It cannot be shared among several VMs. I noticed that there are several projects implementing the virtualization of GPU devices on Xen, such as vCUDA (Hunan University, CN, 2009) and GViM (Georgia IT). But, is there any plan with Xen support the GPU virtualization in the Xen official code?

(Xen already has spice support in Xen 4.2, and making QXL working is possible when xen-unstable switches to using the most recent Qemu upstream branch during the Xen 4.3 development cycle) Hopefully those links help.. -- Pasi > Best Regards, > Bei Guan > ^ permalink raw reply [flat|nested] 6+ messages in thread
