In my case, I have:<br> <br> 02:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.<br> [AMD/ATI] Pitcairn XT [Radeon HD 7870 GHz Edition] [1002:6818]<br> 02:00.1 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI]<br> Cape Verde/Pitcairn HDMI Audio [Radeon HD 7700/7800 Series]<br> [1002:aab0]<br> <br> and pass these through using<br> -device vfio-pci,host=02:00.0,addr=00.0,multifunction=on \<br> -device vfio-pci,host=02:00.1,addr=00.1 \<br> <br> however, in the guest the 1002:aab0 HDMI Audio shows up under system<br> devices as a "High Definition Audio Bus" rather than an HDMI<br> device/controller, and what shows up as the "AMD High Definition Audio<br> Device" itself is something which is 1002:aa01. Where does this<br> 1002:aa01 come from? Is this correct that 1002:aab0 device at 02:00.1<br> is the "bus"? As a result of this behavior, a completely different<br> device as "Acer DynaVivid Graphics Dock" is showing up on my system as<br> a result of the "High Definition Audio Bus" after installing AMD<br> drivers. None of my devices are Acer, and certainly nothing should be<br> a graphics dock?<br> <br> Regards,<br> MB<br> <br> </div><div class="elided-text">_______________________________________________<br> vfio-users mailing list<br> <a href="mailto:vfio-users@redhat.com">vfio-users@redhat.com</a><br> <a href="https://www.redhat.com/mailman/listinfo/vfio-users" rel="noreferrer" target="_blank">https://www.redhat.com/mailman/listinfo/vfio-users</a><br> </div></blockquote></div> <br></div><br></body></html>
