Hi everybody,
This patchset is intended to provide a start for implementing the
emulation of the AMD IOMMU. For those who aren't aware yet, I intend
to participate as a student in GSoC 2010.
The patches are meant to be applied on top of qemu-kvm.
In short, this demonstrates a mechanism of inserting ACPI tables without
modifying SeaBIOS or other BIOS implementations. I also have a SeaBIOS
equivalent, but I think this approach is better, at least at the moment.
To test, simply boot a Linux kernel inside KVM and look in dmesg for the
IVRS table.
I wouldn't merge this patchset yet, at least stuff after the first patch,
until it accumulates more work. I also didn't test loading ACPI tables from
the command line after these modifications.
I'd appreciate comments on these patches.
Cheers,
Eduard
