[vfio-users] How to make use of UPT mode GPU

[Daimon Wang]

Hi,    I've setup an VM with UPT mode, with qxl as the primary graphic device. According to "igd-assign.txt", the pass-throughed GPU is the secondary device and could enable hardware acceleration for the qxl. But what I've got is an normal qxl display, without acceleration.
    I'm playing with an Nvidia K2200 device, and have the nvidia offcial/newest driver installed. I've tried with both Win7_x64/Ubuntu 14 VM, none seems to work.
    On the Ubuntu VM, when I set qxl as the only device in xorg.conf, the nvidia-setting program tells me "There seems no X running on nv device". While if I run nvidia-xconfig, it set the nv as the only device in xorg.conf and I get nothing on qxl output (blank on vt7, text console on vt1).
    On Win7_x64 VM, when both card are enabled, the "dxdiag" shows there's no acceleration enabled. And if I disable the qxl device, the dxdiag output is as expected.

    Is ther any hw/config required to enable the acceleration on qxl?

Regards,Daimon
