I have a system with an i5-2500K CPU and an Asus P8H67M-EVO mobo.  I want to be able to use the firewire on the mobo for changing channels on a cable box.

 

When I go to system devices I see

03:00.0 FireWire (IEEE 1394) [0c00]: VIA Technologies, Inc. VT6315 Series Firewire Controller [1106:3403] (rev 01)

 

So I changed my syslinx entry to the following:

default /syslinux/menu.c32
menu title Lime Technology, Inc.
prompt 0
timeout 50
label unRAID OS
  menu default
  kernel /bzimage
  append vfio-pci.ids=1106:3403 initrd=/bzroot

 

But I still don't see any PCI devices available.  Did I do something wrong or is this perhaps not supported on my hardware - note that my CPU does not support Vt-d?  Would I have better luck with a PCI or PCIe firewire card?

 

Or is the vfio-pci.ids the wrong syntax?  I can't seem to find much documentation on stubbing.  I based what I did on a thread here for a beta version of unRAID 6.2

 

When I do a dmesg |grep -i vfio I get

[    0.000000] Command line: BOOT_IMAGE=/bzimage vfio-pci.ids=1106:3403 initrd=/bzroot
[    0.000000] Kernel command line: BOOT_IMAGE=/bzimage vfio-pci.ids=1106:3403 initrd=/bzroot

[   10.522712] vfio_pci: add [1106:3403[ffff:ffff]] class 0x000000/00000000

So I changed my syslinx entry to the following:

default /syslinux/menu.c32
menu title Lime Technology, Inc.
prompt 0
timeout 50
label unRAID OS
  menu default
  kernel /bzimage
  append vfio-pci.ids=1106:3403 initrd=/bzroot

I know pretty much nothing, but I have been playing around with this a bit today. I think maybe what you want to use is pci-stub.ids=1106:3403. I could be wrong.

 

If you're not sure whether you have VT-d or not, in the Unraid GUI click on Info in the upper right hand corner just below Uptime. IOMMU should say Enabled. If not, you either have to enable it in the bios or you don't have it.

IOMMU shows up as being disabled.  Either my CPU/mobo doesn't support it or it isn't turned on in the BIOS.

 

Anyone know if this is supported.  I am getting a bad feeling that it isn't

Didn't you see the answer to your question on the other thread?

 

I want to pass through the firewire on my mobo to VMs, either Ubuntu or Windows, on my unRAID server.  My CPU is an i5-2500K which does not support Vt-d.  My mobo is an Asus P8H67M-EVO.

 

Here is the output of an lspci -tv:

The Sony USB is the drive holding my unRAID install.

 

Is it possible for me to passthrough the firewire which is on 1c.3?  If so how would I do that?

 

You need vt-d to pass through devices, so it's not possible.

Ok thanks - it is weird that the i5-2500K doesn't have Vt-d but the i5-2500 does.  And the K variants were/are more expensive as they are able to be OC'ed.

 

Maybe I should look at getting a used Sandy Bridge processor that supports Vt-d like an i7-2600 or an i5-2500 non K versions.  If I can get them cheaply on fleabay that is a simple upgrade.
