Subject: Device is ineligible for IOMMU domain attach due to platform RMRR requirement
Date: Fri, 06 Mar 2015 00:20:43 -0500	[thread overview]
Message-ID: <54F9392B.3060102@hp.com> (raw)

I am attempting on ubuntu 14.04 to configure PCI passthrough of a NVidia 
K40 GPU card that is plugged into a HP DL580 rack mounted server.
I have done all of the pre-work I normally have done in the past with 
pci-stub, vfio and etc but when I try an execute a qemu-system-x86_64 
command that works on a similar version of debian, I get the following 
error in the dmesg:

Device is ineligible for IOMMU domain attach due to platform RMRR 
requirement. Contact your platform vendor.

I have read through the patch description from Alex at:

http://lists.linuxfoundation.org/pipermail/iommu/2014-June/008816.html

and I have read the IOMMU documentation at:

https://www.kernel.org/doc/Documentation/Intel-IOMMU.txt

but I am still not really understanding if or what the fix is for this.

The ubuntu 14.04 system where I am getting this error is running 
3.16.0-30-generic
The debian system where I can do similar PCI passthrough of a NVidia K2 
GPU device is running a 3.14.29-4 kernel.

Can anyone provide any insight into an fix or workaround for this?

Thanks in advance.
