Hi all, Has anyone experienced weird behavior when assigning HDMI function of GPU along with the GPU itself in Windows guest? In my case, I have:
02:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Pitcairn XT [Radeon HD 7870 GHz Edition] [1002:6818] 02:00.1 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI] Cape Verde/Pitcairn HDMI Audio [Radeon HD 7700/7800 Series] [1002:aab0] and pass these through using -device vfio-pci,host=02:00.0,addr=00.0,multifunction=on \ -device vfio-pci,host=02:00.1,addr=00.1 \ however, in the guest the 1002:aab0 HDMI Audio shows up under system devices as a "High Definition Audio Bus" rather than an HDMI device/controller, and what shows up as the "AMD High Definition Audio Device" itself is something which is 1002:aa01. Where does this 1002:aa01 come from? Is this correct that 1002:aab0 device at 02:00.1 is the "bus"? As a result of this behavior, a completely different device as "Acer DynaVivid Graphics Dock" is showing up on my system as a result of the "High Definition Audio Bus" after installing AMD drivers. None of my devices are Acer, and certainly nothing should be a graphics dock?
