Supporting per device MSI domains on ARM64, RISC-V and the zoo of interrupt mechanisms needs a bit more information than what the initial x86 implementation provides. Add the following fields: - required_flags: The flags which a parent domain requires to be set - bus_select_token: The bus token of the parent domain for select() - bus_select_mask: A bitmask of supported child domain bus types This allows to provide library functions which can be shared between various interrupt chip implementations and avoids replicating mostly similar code all over the place.

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.
