Allow MSHV_ROOT_HVCALL IOCTL on the /dev/mshv fd. This IOCTL would execute a passthrough hypercall targeting the root/parent partition i.e. HV_PARTITION_ID_SELF. This will be useful for the VMM to query things like supported synthetic processor features, supported VMM capabiliites etc. Since hypercalls targeting the host partition could potentially perform privileged operations, allow only a limited set of hypercalls. To begin with, allow only: HVCALL_GET_PARTITION_PROPERTY HVCALL_GET_PARTITION_PROPERTY_EX Signed-off-by: Anirudh Rayabharam (Microsoft) <anirudh@anirudhrb.com> Reviewed-by: Nuno Das Neves <nunodasneves@linux.microsoft.com> Signed-off-by: Wei Liu <wei.liu@kernel.org>
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.
