Hi
I am trying to port a Haswell laptop and I would want it to have
IOMMU support. My chipset supports VT-d but CPU does not. The
official info from Intel says the PC needs chipset, CPU and BIOS to
support VT-d to use IOMMU. I think this is not true because I saw
some boards in board status have working IOMMU with no VT-d support
in chipset but with coreboot advertising DMAR table to OS and CPU
with VT-d support. Sapphire H61 is a example of this. But other H61
coreboot boards such as P8H61-M
LX that have
CPU without VT-d advertise no IOMMU capability. So what
is really required for full IOMMU ? Do I have chance for full,
working IOMMU on this laptop?
Thanks,
Lud
