Detect the Bhyve hypervisor and enable 15-bit MSI support if available. Detecting Bhyve used to be a purely cosmetic issue of the kernel printing 'Hypervisor detected: Bhyve' at boot time. But FreeBSD 15.0 will support¹ the 15-bit MSI enlightenment to support more than 255 vCPUs (http://david.woodhou.se/ExtDestId.pdf) which means there's now actually some functional reason to do so. ¹ https://github.com/freebsd/freebsd-src/commit/313a68ea20b4 [ bp: Massage, move tail comment ontop. ] Signed-off-by: David Woodhouse <dwmw@amazon.co.uk> Signed-off-by: Borislav Petkov (AMD) <bp@alien8.de> Acked-by: Ahmed S.

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.
