[PATCH 0/2] Memory and PCI definitions for emulated ATS

2025-06-19 Thread CLEMENT MATHIEU--DRIF
This short series adds the 'address type' bit (concept from PCIe) to the memory attributes and extends the IOMMUAccessFlags enum. This will be required to implement ATS support for the virtual IOMMUs. Address type: Field present in the PCIe R/W requests, it allows devices to tell the IOMMU if the
