Now we have a new IOMMU_RESV_DIRECT_RELAXABLE reserved memory region type, let's report USB and GFX RMRRs as relaxable ones. We introduce a new device_rmrr_is_relaxable() helper to check whether the rmrr belongs to the relaxable category. This allows to have a finer reporting at IOMMU API level of reserved memory regions. This will be exploitable by VFIO to define the usable IOVA range and detect potential conflicts between the guest physical address space and host reserved regions.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
