Our fault injection mechanism is mildly primitive, and doesn't really implement the architecture when it comes to reporting the level of a failing S1 PTW (we blindly report a SEA outside of a PTW). Now that we can walk the S1 page tables and look for a particular IPA in the descriptors, it is pretty easy to improve the SEA injection code. Note that we only do it for AArch64 guests, and that 32bit guests are left to their own device (oddly enough, I don't fancy writing a 32bit PTW...).

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 reStructuredText 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.
