lcx pcie passthrough

I'm trying to pass through a GPU device to an LCX container but I can't seem to find the device to pass through to the container. lspci -nnk: ``` 64:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Phoenix3 [1002:1900] (rev c5) Subsystem: Device [2014:8001]...

I have been looking for hours and cannot find anything that is actually helpful. I want to pass a Hauppauge PCIe WinTV-QuadHD into an LXC. I Can find a bunch of gpu to LCX but not complete walk-throughs and even more USB to LXC. Any help with finding a walk-through or advice on how to get it...
