4 IGD has two different modes for assignment using vfio-pci:
6 1) Universal Pass-Through (UPT) mode:
8 In this mode the IGD device is added as a *secondary* (ie. non-primary)
10 This mode *requires* guest driver support to remove the external
12 drivers only support this mode for Broadwell and newer IGD, according to
13 Intel. Additionally, this mode by default, and as officially supported
15 this mode either to provide hardware acceleration to the emulated graphics
16 or to use this mode in combination with guest-based remote access software,
17 for example VNC (see below for optional output support). This mode
