[PATCH 0/8] acpi_build: Refactor and cleanup AMD IVRS build

Posted by Sairaj Kodilkar 2 weeks, 5 days ago

This series aims to improve redability and maintainibility of the the AMD IVRS
building by introducing macros and packed structs which represents IVRS, IVHDs
headers and IVHD device entries.

The goal is to land a maintainable baseline before adding AMD
hardware-accelerated vIOMMU support in QEMU, where we will require multiple
vIOMMUs attached to different pcie-pxb buses in order to serve set of
passthrough devices.

Please refer to AMD IOMMU spec [1] for more details about IVRS.
