I was pointed towards this thread when I had trouble isolating my 1070 for PCI passthrough. Long story short, I tried dumping my vBIOS like instructed in the video, but couldn't do so (the `cat` command printed I/O errors instead). Instead, I resorted to dumping the full vBIOS under Windows and using a hex editor to splice the relevant part of the ROM into a new file, using some of the partial vBIOS files uploaded here as samples. This finally allowed me to pass the GPU to the Windows VM! --- Anyway, I wrote a Python script that should automate this process (you give it a full ROM from techPowerUp or one you dumped using nvflash under Windows), and it should create a patched ROM that you can use to make GPU passthrough work. I passed a few ROMs I downloaded from techPowerUp through the script and compared them to what you guys uploaded here, and so far the Pascal vBIOS files appeared to match, bit by bit. Still, I can't stress it enough that this script is based on guesswork, so it may end up bricking your GPU if you're unlucky. It does a few rudimentary sanity checks, but I would recommend dumping the partial ROM yourself if you can. Still, for those who are pulling your hair out over not being able to do that, this may be a lifesaver. https://github.com/Matoking/NVIDIA-vBIOS-VFIO-Patcher
