[SOLVED] Enable IOMMU on x79 Mobo

I trying to enable GPU pass through to my VM.   I am unable to enable IOMMU.   Is this a config issue or is due to the motherboard?

 

Here my system info from GUI:

M/B: X79 Version To be filled by O.E.M. - s/n: To be filled by O.E.M.

BIOS: American Megatrends Inc. Version 4.6.5. Dated: 06/10/2019

CPU: Intel® Xeon® CPU E5-2650 v2 @ 2.60GHz

HVM: Enabled

IOMMU: Disabled

 

From command line:

root@Tower:~# dmesg | grep -ie iommu
[   14.443752] AMD IOMMUv2 driver by Joerg Roedel <[email protected]>
[   14.443940] AMD IOMMUv2 functionality not available on this system

 

I didn't see anything in BIOS that had anything to do with IOMMU.  I've made sure that Intel Virtualization (VT-d) is enable.   Does this motherboard x79 support IOMMU or is there BIOS that I may have missed?

 

Attached is my hardware profile.

 

Thanks

 

NV - I have found the answer:

 

In AMI Bios go to 'Chipset' ->North Bridge->'Intel (R) VT for Directed I/O Configuration'->Intel(R) VT-d (enable)
