[vfio-users] vga passthrough Zotac GTX 1060 3G

[Jiri Novak]

Hi,

previuosly I've successfully passed radeon cards on the same box. now
I'm trying to pass Zotac GTX 1060 3G (both to new or the old VMs) and
can't get past:
Running option rom at c000:0003 - if I don't specify romfile
Booting from 0000:7c00 - if I specify romfile, the VM doesn't boot though.
no output at all on serial console if I try to boot with -bios
/usr/share/qemu/OVMF.fd

logs with and without romfile in attachements, those would be long

any ideas what to try next?

the qemu commandline (if you have any other hints regarding better
options, I'd appreciate it. especially if I can better map what cpus are
used for which vcpu):
