Hello,
This series introduces AMD IO MMU emulation to qemu. It's the third version.
Changes since v2.
-Coding style; fixed all errors reported by scripts/checkpatch.pl as
suggested by Micheal
-Implemented read/only and write 1/clear registers to IO MMU MMIO
-Cleaned up dead code
-Introduced a switch that controls IO MMU emulation and what type is emulated
i.e
q35,iommu=amd|intel
as suggested by Marcel
-Tested with audio device passthrough (ac97 with sound driver alsa)
-Reserved memory for IO MMU MMIO via ACPI (I need someone to check this)
I was supposed to implement interrupts related to w1/c registers but I decided
to reserve everything to do with interrupts for later
Testing procedure outlined here
