The sclp interrupt is kind of special. The ultravisor polices that we do not inject an sclp interrupt with payload if no sccb is outstanding. On the other hand we have "asynchronous" event interrupts, e.g. for console input. We separate both variants into sclp interrupt and sclp event interrupt. The sclp interrupt is masked until a previous servc instruction has finished (sie exit 108).

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.
