[PATCH intel_iommu 0/7] FLTS for VT-d

[CLEMENT MATHIEU--DRIF]

This series is the first of a list that add support for SVM in the Intel IOMMU.

Here, we implement support for first-stage translation in VT-d.
The PASID-based IOTLB invalidation is also added in this series as it is a
requirement of FLTS.

The last patch introduces the 'flts' option to enable the feature from
the command line.
Once enabled, several drivers of the Linux kernel use this feature.

This work is based on the VT-d specification version 4.1 (March 2023)

Here is a link to a GitHub repository where you can find the following elements 
:
    - Qemu with all the patches for SVM
        - ATS
        - PRI
        - PASID based IOTLB invalidation
        - Device IOTLB invalidations
        - First-stage translations
        - Requests with already translated addresses
    - A demo device
    - A simple driver for the demo device
    - A userspace program (for testing and demonstration purposes)
