Need some help with GPU Passtrough AMD HD 6000

[sebo]

Hi,

 

im new to Unraid and first i have to say im very happy with it, but im actually tryin to Passtrough a Graphics Card to a Windows 10 VM, here my Info Page :

 

Model: HP Microserver Gen8

M/B: -

CPU: Intel® Xeon® CPU E31220L @ 2.20GHz

HVM: Enabled

IOMMU: Enabled

Cache: 64 kB, 512 kB, 3072 kB

Memory: 12288 MB (max. installable capacity 16 GB)

Network: eth0: 1000Mb/s - Full Duplex

eth1: 1000Mb/s - Full Duplex

Kernel: Linux 4.1.18-unRAID x86_64

but gettin the following errors :

 

2016-05-29T19:13:53.376163Z qemu-system-x86_64: -device vfio-pci,host=07:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on: vfio: failed to set iommu for container: Operation not permitted

Please help

[sebo]

PS ive already tried to replace the qemu.conf file from the hotfix ....

[sebo]

ive also tried to modify the syslinux.cfg to

 

append vfio_iommu_type1.allow_unsafe_interrupts=1 initrd=/bzroot

[SpaceInvaderOne]

i had a gen8 microserver and i had the exact same problem with the exact same error displayed.

 

The error was due to "Device is ineligible for IOMMU domain attach due to platform RMRR requirement"

Basically the hp bios is reserving a part of the memory(Reserved Memory Region Reporting

structure) and as such the passthrough fails as the iommu group cant be set.

 

I found no solution im afraid, but that was last year. I would advise updating mb to lastest bios ( or even try older ones) and see if that helps.

[sebo]

Thank you for these information, im afraid this is the latest bios version, but i will try older ones and report how its working.
