This is in proxmox?

How can I tell if my mobo even supports it?

  This may also help, my HBA is there:

    You should be good to go. Make sure vfio is loaded in the modules-load.d
    
    vfio vfio_iommu_type1 vfio_pci vfio_virqfd
    
    Make sure the module options are set correctly and the kernel module is blacklisted in /etc/modprobe.d/vfio.conf
    
    options vfio-pci ids=1000:0097 blacklist MODULE_NAME
    
    Make sure.IOMMU is enabled in your kernel command line (ex via grub): intel_iommu=on IOMMU=pt

  sorry this took so long… you know, life. trying that command altogether, I get this response: -bash: acpidump: command not found
  
  trying just egrep “DMAR|IVRS” (in case they are two commands) seems to hang the terminal session.
  
  I tried following a guide to enable PICe passthrough and get this. One important thing, there is no discrete GPU at the moment, I’m trying to pass through an HBA…
