[Qemu-devel] [PATCH-for-4.0 v2 2/2] hw/arm/virt-acpi-build: IORT Update for revision D |
Date: |
Thu, 6 Dec 2018 18:07:33 +0100 |
Let's update the structs according to revision D of the IORT
specification and set the IORT node revision fields.
In IORT smmuv3 node: the new proximity field is not used as
the proximity domain valid flag is not set. The new DeviceId
mapping index is not used either as all the SMMU control
interrupts are GSIV based.
In IORT RC node: the new memory address size limit field is
set to 64 bits.
Signed-off-by: Eric Auger <address@hidden>

v1 -> v2:
- separate patches for SMMUv3 DMA coherency issue and struct
update to revision D.
- revision fields set
