[Qemu-arm] [RFC v4 4/5] hw/arm/virt: Add 2.10 machine type |
Date: |
Sat, 13 May 2017 19:43:18 +0200 |
The new machine type allows smmuv3 instantiation. A new option
is introduced to turn the feature on/off (off by default).
Signed-off-by: Eric Auger <address@hidden>

Another alternative would be to use the -device option as
done on x86. As the smmu is a sysbus device, we would need to
use the platform bus framework. This would work fine
for the dt generation. However the feasibility needs to be
studied for ACPI table generation.
