[-- Attachment #1 --] Hey group, I am also interested in this space of base system. Has anyone pulled the documentation for what is currently available for GPU drivers for base system Robert ________________________________ From: owner-freebsd-virtualization@FreeBSD.org <owner-freebsd-virtualization@FreeBSD.org> on behalf of Nuno Teixeira <eduardo@freebsd.org> Sent: Thursday, June 26, 2025 4:47:36 PM To: Stephan Althaus <Stephan.Althaus@duedinghausen.eu> Cc: virtualization@freebsd.org <virtualization@freebsd.org> Subject: Re: bhyve: GPU passthrough for Nvidia cards Hello Stephan, A year a go I did try passtrhu a dedicated nvidia GTX 1650 while using integrated intel graphics (laptop Lenovo Legion 5 15IMH05). Windows detected card but nvidia drivers install failed at some point. On this laptop I did setup bios to use integrated graphics so I can passthru dedicated nvidia. Think I will give a new try since I follow main. Are you using laptops for this usecase? Thanks!

You surely mean 'newer' NVidia cards, as my GT1030 works with FreeBSD 14.2 Host and ubuntu guest, NVIdia driver 570, (and Win guest btw) out-of-the-box, no kernel/driver modding...
