The Virtual Display feature is to fake a display engine in amdgpu kernel driver, which allows any other kernel modules or user mode components to work as expected even without real display HW. User can get the desktop/primary surface through remote desktop tools instead of displaying HW associated with the GPU. The virtual display feature is designed for following cases: 1)Headless GPU, which has no display engine, while for some reason the X server is required to initialize in this GPU; 2)GPU with head (display engine) but Video BIOS disables display capability for some reason. For example, SR-IOV virtualization enabled Video BIOS often disables display connector. Some S-series Pro-Graphics designed for headless computer also disable display capability in Video BIOS; 3)For whatever reason, end user wants to enable a virtual display (don’t need HW display capability).
