PCI Passthrough device
0000:03:00.0 ‘VGA compatible controller’: Navi 10 [Radeon RX 5600 OEM/5600 XT / 5700/5700 XT] (Reference RX 5700 XT) by ‘Advanced Micro Devices, Inc. [AMD/ATI
After booting into windows and installing the virt io drivers My resolution was able to be changed. however stuck at 1hz. I decided to try install amd drivers first with the auto detect installer and then with the actual rx5700 windows 10 driver package. The auto detect installer could not auto detect the gpu and failed, the actual driver package did “install” but then could not be detected when I tried to launch the driver software. It gave me an error relating to windows driver being taken over and recommend me to change that in an option menu, which i did. To no avail I am still stuck with no working driver beyond basic 1hz display. Any more information I could provide please let me know.
Is iommu enabled on your motherboard? Also which motherboard?
Output of the following on Truenas shell?
dmesg | grep IOMMU

Whats the output of the script postet here:
Whats the output of:
#!/bin/bash
for d in /sys/kernel/iommu_groups/*/devices/*; do
n=${d#*/iommu_groups/*}; n=${n%%/*}
printf 'IOMMU Group %s ' "$n"
lspci -nns "${d##*/}"
done
This lists all your pci devices by IOMMU group.
Save this script as iommu.shbash iommu.sh
[ 0.010478] DMAR: IOMMU enabled#0 (2 banks, 4 counters/bank).

That is a good start! Did you try isolating the GPU? System Settings > Advanced > Isolated GPU Device(s) > Configure
Maybe Truenas is loving that GPU a bit too much to let it passthrough to the VM. Another thing I’ve seen when messing around with passthrough is some devices DEMAND at least a dummy HDMI/Display port header present; not telling you to buy anything, but try plugging a monitor into it for fun at the very least.
The GPU is isolated for sure

I will try plugging a tv into the hdmi port and see what gives.
i am getting a syntax error when trying to run it. how many lines is it supposed to be on? What does the spacing look like?
same results without isolation?

I have tried plugging in a HDMI cable. No difference. I will try to uncheck the isolation just for kicks tonight and report back.
Do you have any suggestions?
