I am working on a university project on Nvidia or any GPU Pass-through in KVM. I have a question related to framebuffer. I was reading few documents on XEN VGA pass-through, the document says the first step for pass-through is mapping the framebuffers in the VM at specific address, specifically speaking 0xA0000 till 0xC0000. I am not sure how the new framebuffer interface /dev/fbn works. Would I need to map the host framebuffer at specific address in the Guest VM? Or should it be done differently with the help of /dev/fbn interface? Please share your thoughts. Any pointers will be helpful. Please add in CC as I am not subscribed to this mailing list. Thanks and Regards, Prasad
