productive. I found out about GPU passthrough a couple years ago. I decided to try it on my new laptop, which I just got on Monday. Following Arch and Gentoo's guides (I run Gentoo) I have it working, except for one thing: Windows does not recognize the GPU as an NVIDIA RTX 3060M. The PCI

Hi, I did run in a similar issue a few weeks ago. I don't have a solution, but maybe some of my experience is helpful. After updating Windows 10 to build 1909 I got the error 43 for my passed-through GPU. It doesn't change with build 2004. I did changed the graphic card - no change. For test

Hi, hoping someone can help with this. I ran into several snags trying to setup GPU passthrough on my box. It is the only GPU, thus primary. efifb claims mem region on the GPU so it has to be blacklisted completely, even disabling it with video=efifb:off is not enough, the console would no

Hi all, I'm wondering if there is a possibility to pass through a big GPU like the NVIDIA Tesla K80 (with 24 GB ram). AFAIK, there is a problem with mapping that lot of memory which would need 64 bit MMIO (or "above 4G mapping" feature, like some firmware are calling it). So after some searc
