I found a budget gaming notebook that has a
Mobile Intel HM175 chipset and a Intel Core i5 (7th Gen) 7300HQ CPU. Both the CPU and the chipset seem to support Intel® Virtualization Technology for Directed I/O (VT-d).
Can I expect this notebook to support IOMMU properly? Or is there a chance that the manufacturer didn’t add the feature to the UEFI or something like that?
No, the manufacturer has to enable it in the bios so there no guarantees that it’ll work and in most cases it is likely that it isn’t supported.
@Dje4321 tried to get this working on her laptop which both had a cpu and chipset that supported VT-d but the bios by Lenovo had it disabled and no switch to turn it on.
The thread about it is here if you want to read:
So ive been trying todo PCIe passthrough on my laptop but ran into some issues. Virtual Machine Manager complains about the host not supporting pcie passthrough even though i do have support for it. My cpu has VT-d and VT-x support and i dont have any issues with my iommu groups
