Today the parent domain (s2_domain) is unaware of which DID's are used by and which devices are attached to nested domains (s1_domain) nested on it. This leads to a problem that some operations (flush iotlb/devtlb and enable dirty tracking) on parent domain only apply to DID's and devices directly tracked in the parent domain hence are incomplete. This tracks the nested domains in list in parent domain. With this, operations on parent domain can loop the nested domains and refer to the devices and iommu_array to ensure the operations on parent domain take effect on all the affected devices and iommus.

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.
