HP GEN8 GPU pass through AMD

[comdex]

Hi there, 

 

New to unRAID... i have read all over the web about this issue but havent managed to rectify and fix it... 

As far as I understand its not a problem that unRAID show the console output through HDMI of the Radeon HD6450 however when I try to pass through this GPU to a VM i get the following

 

internal error: qemu unexpectedly closed the monitor: 2017-07-05T20:25:58.673496Z qemu-system-x86_64: -device vfio-pci,host=07:00.0,id=hostdev0,bus=pci.0,addr=0x6: vfio: failed to set iommu for container: Operation not permitted

Please advice 

 

Thanks in advance

OK so the newer hp bios does not play nice with newer linux kernel quite often. Without seeing your full diagnostics, 07:00.1 is probably the audio portion of your GPU causing problems.

 

My entire thread about it is here:

 

The last post in the thread has a bios fix that might be applicable to you.

 

 

If the bios fix isn't applicable, then you'll have to follow the steps outlined in the thread to split the GPU video and it's audio component into separate IOMMU groups, and then only pass through the video part and figure out something else for audio (like usb audio, or an audio card.)

also, don't have unraid use same graphic output as your vm. I guess some do it? But it seems to cause more problems than not. If the server doesn't have onboard graphics, get a cheap nvidia card for 20-30 buck, let unRaid use that, and save yourself a headache.
