sigma and IOMMU groups

[qix67]

Hi,

I have a question relative to virtualization on sigma.

i5-1340P supports vt-d however it is only usable if IOMMU groups are properly defined which is rarely the case. Most of the time, most if not all peripherals/component are in the same group making vt-d useless.

Can you tell me how are defined IOMMU groups on sigma ? If you don't have the informations, this can be done with this script
iommu_script.zip

Thanks.
