Hi Everyone!

 

I've got a bit of an odd configuration.. I have this weird industrial motherboard (ASRock IMB-770) that is highly configurable (for POS systems or something.) It's got the intel Q77 Chipset and an i7-3770S, and most notably, 4 plain ol' 33MHz PCI slots. My goal with this particular machine is to do retro gaming and run older software and pass through an older PCI GPU, sound card, and usb controller so that there is full windows 98/2000/XP compatibility.

 

Unfortunately, I am having issues getting the video card to attach. I've tried all 4 pci slots, iommu and VT is enabled, allow_unsafe_interrupts is set to 1, etc.

All QEMU returns is 'internal error: qemu unexpectedly closed the monitor'

3236: error : qemuMonitorIORead:586 : Unable to read from monitor: Connection reset by peer
3236: error : qemuProcessReportLogError:1807 : internal error: qemu unexpectedly closed the monitor

 

The PCI bridge and video card are in their own IOMMU group, do I need to somehow pass through the PCI bridge as well?

IOMMU group 10
	[8086:244e] 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev a4)
	[1002:4755] 03:04.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Mach64 GTB [3D Rage II+ DVD] (rev 9a)

 

Do any of you more experienced vfio vets have any suggestions? I hope we can make this thing work.

 

Thanks!!

more specific title

I think you need a video card with UEFI BIOS to do a pass through.

That would be a total bummer if so.. In the BIOS, I can select Integrated, PCIe, or PCI as a video device. The system will post and boot successfully to unraid using any of the 3 cards- a GeForce 210, ATI Mach64, or the i7's integrated... Does this shed any more light or clues to the situation? If the PCI card initializes through the bios successfully, does that mean that it still needs to be UEFI for vfio to send it a reset and map it to the VM?

 

I also had diffuculty with other PCI devices until I added them to the boot parameters making the vfio-pci driver attach. (append vfio-pci.ids=blah blah)

 

Another clue might be that it isn't assigned a subsystem (or doesn't have one?)... does that point to a non-uefi problem as well or a different issue?

Sorry, I'm still new to all this unraid stuff. (My main Xeon unraid rig works perfectly but then again I'm not trying to do all this PCI weirdness with it!)

 

Also, here are my IOMMU groups, if it may help:
