In the nestedv2 case, the L1 may register the L2's VPA with the L0. This allows the L0 to manage the L2's dispatch count, as well as enable possible performance optimisations by seeing if certain resources are not being used by the L2 (such as the PMCs). Use the H_GUEST_SET_STATE call to inform the L0 of the L2's VPA address. This can not be done in the H_GUEST_VCPU_RUN input buffer.

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.
