I'm using above script on boot to rebind a mpt3sas controller to vfio-pci so it can be passed through to a VM, works great.. would be nice if UI had similar functionality, where you could select devices to rebind to vfio-pci based upon address so they can be reclaimed from kernel modules that might grab em and prevent em from being passed through.. In my case I have 2 identical cards, one for UnRaid, one for a VM (FreeNAS) so blacklisting mpt3sas would not be desired.

 

I'd expect it to work for PCIe SSD's too since I didnt see any of them available to be passed through.. tho im not needing em, yet.

You don't need the script for it. Simply add xen-pciback.hide=(pci number)(next PCI number) in the syslinux.cfg. 

ah I did not find that option, everything I found was trying to use PCI ID's and that was not gonna work since they were both the same.

 

# lspci -nn |grep SAS

Thank you, I dont like this script solution im using now.. felt like a big hack waiting to break on update.. I still feel it would be a useful UI feature, I'm happy editing boot options to get devices to passthrough, but I get a feeling a large part of the unraid audience are more windows users (or at least SMB gets more love than NFS)

We integrated this script in 6.7.0-rc1, check it out!
